2.If either LED is green and the other is OFF the power supply is probably not plugged in. If it is red, the supply is either plugged in and not switched on or it is faulty. It may be necessary to interrogate the system for further status using the CLI.

Chassis Cooling

The hot-swappable chassis fan tray (WS-X4992) provides cooling air for the internal chassis components. The fans draw air in from the right side of the chassis and exhaust the heated air through perforations on the right side of the chassis.

Caution When the fan tray is removed, internal circuitry is exposed that should not be touched by tools or fingers. The system should not operate without a fan tray for longer than is necessary to replace a faulty fan tray with a new fan tray.

Figure 1-4 shows the direction of airflow through the switch.

Figure 1-4 Catalyst 4900M Chassis Airflow

There are five fans in the fan tray. If an individual fan fails, the other fans continue to run. Sensors monitor the internal air temperatures. The number of fans in operation and their speed varies according to the internal temperature for the quietest operation possible. If the air temperature exceeds a desired threshold, the environmental monitor displays warning messages.

Note Individual fans in the fan tray cannot be replaced; the entire fan tray must be replaced.

Power Supplies

Note For complete power specifications for the Catalyst 4900M switch, see , “Specifications.”

The Catalyst 4900M switch has two redundant internal 1000 W AC-input or 1000 W DC-input power supplies.

The internal power supplies have individual power cords and status LEDs (PS1 and PS2 on the front panel). There are also LEDs on the power supplies that show status for the input (Input OK) and output (Output OK) currents. A power cord is used to connect the power supplies to the site AC source. There is a power switch on the AC-input power supplies; AC power is present when a power cord is plugged into a power supply and the switch is set to the On position. DC-input power supplies attach to source DC using customer-supplied cables.

The switch starts with only one power supply plugged in, but redundant failover and load sharing is not available in this configuration. Cisco recommends that you always connect both power supplies to separate AC or DC circuits for optimal power reliability.

For safety reasons, the AC power supply must be switched off and unplugged before it is removed from a chassis or inserted into a chassis. DC supplies should have power shut off from the source before they are removed.

If only one power supply is used, you must use the supplied blank faceplate to cover the empty power bay. The blank power supply cover maintains EMI shielding and proper air flow through the chassis.

Environmental Monitoring of the Power Supplies

Using the environmental monitoring and reporting functions, you can maintain normal system operation by resolving adverse environmental conditions prior to loss of operation.

Each power supply monitors its own temperature and output voltages. The Catalyst 4900M switch senses the operating condition of the power supply and reports status through software.

Power Management for the Catalyst 4900M Switch

You can select either AC-input or DC-input power supplies for your switch. The Catalyst 4900M switch supports the following power supplies:

- 1000 W AC-input

- 1000 W DC-input

A redundant power supply can be identified and diagnosed by a running system regardless of its input status. The AC-input and DC-input supplies are interchangeable.

Power Management Modes

The Catalyst 4900M switch supports the redundant power management mode. In this mode, if both power supplies are operating normally, each provides from 20/80 to 45/55 percent of the total system power requirements at all times. If one power supply fails, the other unit increases power to 100 percent of the total power requirement.

Catalyst 4900M Half-Card Modules

The Catalyst 4900M switch chassis has two half-card slots available allowing two half-card modules to be installed. The following half-card modules are available:

- WS-X4920-GB-RJ45 Half-Card Ethernet Module

- WS-X4904-10GE Half-Card Ethernet Module

- WS-X4908-10GE Half-Card Ethernet Module

Note TwinGig converter modules may be installed in place of X2 transceiver modules if you need 1-GB SFP transceiver connections. When you insert the TwinGig into one port, its neighbor port automatically converts to 1 GE interfaces whether it has a TwinGig installed or not, so you must position your TwinGig converters next to each other. The neighboring port to a TwinGig port cannot support an X2. Installation documentation for Cisco TwinGig converter modules can be found at: http://www.cisco.com/en/US/docs/switches/lan/catalyst3750e_3560e/hardware/install/notes/1757202.html

Note When using TwinGig converters and X2 transceivers on this module, keep them grouped in pairs as follows: ports 1–2, ports 3–4, ports 5–6 and ports 7–8. Inserting a TwinGig converter or X2 transceiver in any port will affect the capability of its neighbor port, and both will be set to handle the same type automatically. Mixing within a port group does not work. As an example, you would not be able to have an X2 transceiver in port 1 and a TwinGig converter in port 2.

Site Planning

This chapter describes how to prepare your site for installation of the Catalyst 4900M switch and contains these sections:

- Site Environmental Requirements

- Site Power Requirements

- Grounding Requirements

- Safety Overview

- Site Planning Checklist

Note A site planning checklist is provided on page 2-8 to help ensure that you complete all site planning activities before you install the switch.

Site Environmental Requirements

Planning a proper location for the switch and layout for your equipment rack or wiring closet is essential for successful system operation. You should install the switch in an enclosed, secure area, ensuring that only qualified personnel have access to the switch and control of the environment. Equipment that is placed too closely together or that is inadequately ventilated can cause system overtemperature conditions. In addition, poor equipment placement can make chassis panels inaccessible and difficult to maintain.

The switch operates as a standalone system mounted in a rack in a secure wiring closet. It requires a dry, clean, well-ventilated, and air-conditioned environment. To ensure normal operation, maintain ambient airflow. If the airflow is blocked or restricted, or if the intake air is too warm, an overtemperature condition can occur. The switch environmental monitor can then shut down the system to protect the system components.

F). It is essential to keep the area around the chassis as free from dust and foreign conductive material (such as metal flakes from nearby construction activity) as is possible.

Multiple switches can be rack-mounted with little or no clearance above and below the chassis. However, when mounting a switch in a rack with other equipment, or when placing it on the floor near other equipment, ensure that the exhaust from other equipment does not blow into the intake vents of the chassis.

Cooling air is drawn in through the right side and exhausted through the left side of the chassis. Keep the sides and rear clear of obstructions, including dust and foreign conductive material, and away from the exhaust ports of other equipment.

are those within which the switch will continue to operate; however, a measurement that approaches the minimum or maximum of a range indicates a potential problem. You can maintain normal operation by anticipating and correcting environmental anomalies before they exceed the maximum operating range. Specificationslists the operating and nonoperating environmental site requirements for the switches. To maintain normal operation and ensure high system availability, maintain an ambient temperature and EMI-free and continuous power at your site. The environmental ranges listed in

Site Power Requirements

This section describes the installation site power requirements for the Catalyst 4900M switch. Verify your site power before you install the switch.

This section consists of the following sections:

- Preinstallation Requirements

- Warnings and Cautions

- EMI Recommendations

- Power Requirements and Heat Dissipation

Preinstallation Requirements

Follow these requirements when preparing your site for the Catalyst 4900M switch installation:

- Connect each switch to separate wiring on a dedicated circuit; provide each switch with its own branch circuit connection with sufficient overcurrent protection and direct grounding to the branch circuit.

- To prevent a loss of input power, be sure the total maximum load on each AC circuit is within the current ratings of the wiring and breakers.

Warnings and Cautions

Follow these precautions when preparing your site for the Catalyst 4900M switch installation:

Caution The total maximum load on each AC or DC -input power circuit must be within the rating of the wiring and breaker. An overload of input power can result if this requirement is not met.

Warning Read the installation instructions before connecting the system to the power source. Statement 1004

Warning Installation of the equipment must comply with local and national electrical codes. Statement 1074

Warning Ultimate disposal of this product should be handled according to all national laws and regulations. Statement 1040

EMI Recommendations

Follow these guidelines when setting up the site wiring. When planning the location of the new system, consider electromagnetic interface (EMI), the distance limitations for signaling, and connector compatibility.

When wires are run for any significant distance in an electromagnetic field, radio frequency interference (RFI) can occur between the field and the signals on the wires.

- Bad plant wiring can result in radio frequency interference.

- Strong EMI, especially when caused by lightning or radio transmitters, can destroy the signal drivers and receivers in the switch and can create an electrical hazard by conducting power surges through lines and into equipment.

Note To predict and remedy strong EMI, you might need to consult RFI experts.

This rack-mount kit is not suitable for racks with obstructions (such as a power strip) that could impair access to the switch, four-post rack enclosures that exceed 32.5 inches (82.5 cm) in depth, or for two-post equipment racks.

An optional rack-mounting kit (C4900M-BKTS-KIT=) is available for installing the chassis in two-post telco racks and in four-post equipment racks that exceed 32.5 inches (82.5 cm) in depth.

Caution Before installing the chassis in a rack, read the “Site Environmental Requirements” section to become familiar with the proper site and environmental conditions. Failure to read and follow these guidelines could lead to an unsuccessful installation and possible damage to the system and components.

Caution This unit is meant to be rack-mounted, and is not intended to bear more than its own weight. Do not stack more than two on a table top, the added weight may damage the bottom chassis.

Warning

To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:

- This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

- When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.

- If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack. Statement 1006

Rack-Mounting Guidelines

Before rack-mounting the switch, ensure the following:

- The equipment rack is the proper size.

– The width of the rack, between the two front mounting strips or rails, must be 17.75 inches (45.09 cm).

– The depth of the rack, between the front and rear mounting strips, must be at least 19.25 inches (48.9 cm) but not more than 32.5 inches (82.5 cm).

Note If your four-post rack enclosure exceeds 32.5 inches (82.5 cm) in depth, or you are installing the chassis in a two-post equipment rack, you must order and use the optional rack-mount kit (C4900M-BKTS-KIT=).

– The rack must have sufficient vertical clearance to insert the chassis. The chassis height is 2 U (3.5 inches (8.9 cm)).

- The equipment rack is stable and in no danger of falling over.

– We recommend that you bolt the rack to the floor.

– Mount the unit at the bottom of the rack if it is the only unit in the rack.

– Install heavier equipment in the lower half of the rack to maintain a low center of gravity and prevent the rack from becoming top-heavy and tipping over.

– Install the stabilizers before mounting or servicing the switch in the rack (if the rack is provided with stabilizing devices).

- The equipment rack is properly ventilated.

– Install the chassis in an enclosed rack only if it has adequate ventilation or an exhaust fan; use an open rack whenever possible.

C). Note that if the switch is installed in a closed or multiunit rack assembly, the ambient operating temperature of the rack environment might be higher than the ambient room temperature.

– Note that a ventilation system in a closed rack that is too powerful might also prevent cooling by creating negative pressure around the chassis and redirecting the air away from the chassis intake vent. If necessary, operate the chassis with the rack open.

– To prevent airflow restriction, allow at least 3 inches (7.6 cm) of clearance around the ventilation openings on the sides of the chassis.

– Use baffles correctly to assist in cooling the chassis.

– Note that equipment near the bottom of a rack may generate excessive heat that is drawn upward and into the intake ports of equipment above, leading to overtemperature conditions in the chassis at or near the top of the rack.

– Consider the equipment and cabling that is already installed in the rack. Ensure that cables from other equipment will not obstruct the airflow through the chassis or impair access to the power supplies or switching modules. Route cables away from field-replaceable components to avoid disconnecting cables unnecessarily for equipment maintenance or upgrades.

– Allow at least 3 to 4 feet (91.4 to 121.9 cm) of clearance behind the rack for maintenance and removal of switch assemblies. If the rack is mobile, you can push it back within 1 foot (30.45 cm) of a wall or cabinet for normal operation and pull it out when necessary for maintenance.

Lifting the Chassis Safely

The chassis is not intended to be moved frequently. Before you install the switch, ensure that your site is properly prepared so that you can avoid moving the chassis later to accommodate power sources and network connections.

Whenever you lift a chassis or any heavy object, follow these guidelines:

- Ensure that your footing is solid, and balance the weight of the chassis between your feet.

- Lift the chassis slowly; never move suddenly or twist your body as you lift.

- Keep your back straight and lift with your legs, not your back. If you must bend down to lift the chassis, bend at the knees, not at the waist, to reduce the strain on your lower back muscles.

- Always disconnect all external cables before lifting or moving the chassis.

Required Installation Tools

The following tools and equipment are required to install the chassis:

- Number 1, number 2 Phillips, and 3/16-inch flat-blade screwdriver

- Antistatic mat or antistatic foam

- Your own ESD grounding strap or the disposable ESD strap included with the system

The following tools and equipment are required to install the chassis in a rack:

- Rack-mount kit

- Tape measure and level

Rack-Mounting the Catalyst 4900M Switch

Follow these steps to install the Catalyst 4900M switch in a four-post rack.

Step 1 Prepare for installation:

a. Place the chassis on the floor or on a sturdy table as close as possible to the rack. Leave enough clearance to allow you to move around the chassis.

b. Use a tape measure to measure the depth of the rack. Measure from the outside of the front mounting posts to the outside of the rear mounting strip. The four-post rack depth must be at least 19.25 inches (48.9 cm) but not more than 32.5 inches (82.5 cm). If the 4-post rack depth is greater than 32.5 inches (82.5 cm), order and use the optional rack-mount kit (C4900M-BKTS-KIT=).

c. Measure the space between the inner edges of the left front and right front mounting posts to ensure that it is 17.75 inches (45.09 cm) wide. (The chassis is 17.5 inches [44.5 cm] wide and must fit between the mounting posts.)

Configurable Modules

All Catalyst 4900M modules support hot swapping, which lets you install, remove, replace, and rearrange switching modules without turning off the system power. When the system detects that a switching module has been installed or removed, it runs diagnostic and discovery tests automatically, acknowledges the presence or absence of the module, and resumes system operation with no operator intervention.

This section describes the following topics:

- Required Tools

- Removing Switching Modules

- Installing Switching Modules

Required Tools

You will need these tools to install switching modules in the Catalyst 4900M series switches:

- Number 1 and number 2 Phillips screwdrivers for the captive installation screws

Removing and Replacing the Power Supply

This section describes how to remove and install the AC and DC-input power supplies. This information is presented in the following sections:

- Required Tools

- Removing a Power Supply

- Installing a Power Supply

Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034

Locate your power supply and notice the location of the captive installation screws.

Note The power supplies are hot-swappable, so in redundant mode you will not need to power down the switch to replace most power supplies. In combined mode some slots may lose power during power supply replacement.

Required Tools

You will need a flathead or Phillips screwdriver or 5/16” nut driver or socket to perform these procedures.

Removing a Power Supply

Follow these steps to remove a power supply:

Step 1 Set the power switch to the off (O) position.

Caution For DC installations, the DC power source or panel breaker should be powered down before disconnecting input power cables from the 1000W DC power supply.

Step 2 Disconnect the power cord or cords from the power supply being removed.

Step 3 Loosen the captive screws.

Caution Use both hands to remove a power supply.

Step 4 Grasp the power supply handles and pull the power supply out an inch to unseat the backplane connections. Place one hand underneath to support the bottom of the power supply.

Step 5 Pull the power supply out of the bay and set it aside.

Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement 1029

Step 6 If the power supply bay is to remain empty, install a blank power supply filler plate over the opening. Secure the filler plate with the two mounting screws and tighten them with a screwdriver.

Installing a Power Supply

Warning The plug-socket combination must be accessible at all times, because it serves as the main disconnecting device. Statement 1019

Removing and Replacing the Fan Assembly

This section describes how to remove and install the fan assembly.

Required Tools

You will need a Phillips screwdriver for the following two procedures.

Removing the Fan Assembly

Warning When removing the fan tray, keep your hands and fingers away from the spinning fan blades. Let the fan blades completely stop before you remove the fan tray. Statement 258

Caution Never operate the system for an extended period if the fan assembly is removed or if it is not functioning properly. An over-temperature condition can cause severe equipment damage.

To remove the existing fan assembly, perform the following steps:

Step 1 Loosen the two captive installation screws on the fan assembly by turning them counterclockwise.

Step 2 Grasp the fan assembly with both hands and pull it outward; gently move it side to side if necessary to unseat it from the backplane. Slide it out of the chassis and place it in a safe place.

Installing the Fan Assembly

To install the new fan assembly, perform the following steps:

Step 1 Hold the fan assembly with the captive screws on the left.

Step 2 Place the fan assembly into the fan assembly bay so it rests on the chassis, and then lift the fan assembly up slightly, aligning the top and bottom guides.

Step 3 Slide the fan assembly into the chassis until the two captive installation screws make contact with the chassis.

Step 4 Using a screwdriver, tighten the two captive installation screws by turning them clockwise.

Verifying the Installation

Note To check the operation of the fans, you need to power up the chassis.

To verify that the new fan assembly was installed correctly, perform the following steps:

Step 1 Listen for the fans; you should immediately hear them operating. If you do not hear them, ensure that the fan assembly is inserted completely in the chassis and that the faceplate is flush with the switch back panel.

Step 2 The fan tray LED should be lit green.

Step 3 If after several attempts the fans do not operate, or if you experience trouble with the installation (for instance, if the captive installation screws do not align with the chassis holes), contact the Cisco TAC for assistance.

Troubleshooting the Installation

This chapter describes how to troubleshoot the Catalyst 4900M switch hardware installation and contains these sections:

- Getting Started

- Problem Solving to the System Component Level

- Identifying Startup Problems

- Troubleshooting the Power Supply

- Contacting Customer Service

If your system has problems starting up, use the information in this chapter to help isolate the cause. Problems with the initial startup are often caused by poor or improper connections. Although temperature conditions above the maximum acceptable level rarely occur at initial startup, environmental monitoring functions are included because they also monitor DC-line voltages.

Note For configuration questions or problems, refer to the software configuration guide or the command reference publication to configure or enable the interfaces.

Getting Started

When the initial system boot is complete, verify the following:

- Power supplies are supplying power to the system.

- The system fan assembly is operating.

- System software boots successfully.

If all of these conditions are met and the hardware installation is complete, refer to the software configuration guide and the command reference publications to troubleshoot the software. However, if any of these conditions are not met, use the procedures in this chapter to isolate and, if possible, resolve the problem.

Problem Solving to the System Component Level

. Because a startup problem can usually be attributed to a single component, it is more efficient to isolate the problem to a subsystem rather than troubleshoot each separate component in the system.

The switch consists of the following subsystems:

- Power supply—Includes the power supply and power supply cooling. (See the “Troubleshooting the Power Supply” section.)

- Fan assembly system—The chassis fan assembly should operate whenever system power is on. Usually, it continues to operate even when the environmental monitor shuts down the system because of an overtemperature or overvoltage condition. (It will shut down for a power supply shutdown.) You should be able to hear the fan assembly to determine whether or not it is operating. If the FAN LED is orange and you determine that the fan assembly is not operating, you should immediately contact a customer service representative. There are no installation adjustments that you can make if the fan assembly does not function properly at the initial startup.

Identifying Startup Problems

When you connect the power cords to the Catalyst 4900M switch, follow these steps:

Step 1 Flip the power switches to the on position (AC powered systems only).

Step 2 Verify that power is available to the power supplied from the site AC or DC source. Flip breakers and fuses if necessary.

Step 3 Listen for the system fan assembly. If you do not immediately hear the system fan assembly begin to operate, see “Troubleshooting the Power Supply” section.

Step 4 If you determine that the power supplies are functioning normally and that the fan assembly is faulty, contact a customer service representative. If the system fan assembly does not function properly at initial startup, there are no installation adjustments that you can make.

LED Readings

LEDs indicate all system states in the startup sequence. By checking the LEDs, you can determine when and where the system failed in the startup sequence. To check the LEDs, follow these steps:

.

Table 1-1 Power Supply LED Meanings

LED

Meaning

This LED should turn green immediately when power is applied to the supply and the power switch is set to ON.

Green—AC input voltage is greater than 80.5 VAC ±4.5 VAC.

Red—In a dual power supply configuration (alternate unit powered) the AC input is less than 73 VAC ±3 VAC, or the power supply is turned off.

Off—In a single supply configuration, signals that AC input voltage is less than 73 VAC ±3 VAC, or the power supply is turned off.

This LED should turn green immediately when power is applied to the supply.

Green—DC input voltage is greater than –38.25 VDC ±2.25 VDC.

Red—In a dual power supply configuration (alternate unit powered) the DC input is less than 33 VDC ±3 VDC, or the power supply is turned off.

Off—In a single supply configuration, the LED shall be off to signal that DC input is less than 33 VDC ±3 VDC, or the power supply is turned off.

OUTPUT OK

Green—DC output voltages are within the normal operating range.

Red—Output voltages below the minimum or above the maximum will create an output fail alarm and cause the LED to illuminate red.

Step 2 Verify that the LEDs on the front panel are lit:

- The STATUS LED flashes yellow during diagnostic boot tests. It is green when the switch is operational (online). If the system software is unable to start up, this LED stays orange.

- The port LEDs (1-48) are green when the module is operational (online). If no signal is detected, the LINK LED is off. The port LED remains yellow if the port is disabled. The port LED flashes yellow if the port tested faulty at startup.

Step 3 If a STATUS LED is red, contact a customer service representative for instructions.

Step 4 If the boot information and system banner are not displayed, verify that the terminal is set correctly and that it is connected properly to the console port.

Troubleshooting the Power Supply

To help isolate a power subsystem problem, perform the following steps:

Step 1 Verify that the power supply is plugged in and that the on/off switch is set to ON (if the power supply is an AC supply).

Step 2 Look at the power supply LED (PS1 or PS2). If the LED is off or if the LED is red, unplug the power cord, and then plug the power cord in. Be sure the on/off switch is OFF before removing the power cord from the power supply.

Step 3 If the LED remains off, there might be a problem with the AC or DC source or the power cable.

Step 4 Connect the power cord to another power source if one is available.

Step 5 If the LED then lights, the problem is the first power source.

Step 6 If the LED fails to light after you connect the power supply to a new power source, replace the power cord.

Step 7 If the LED still fails to light when the switch is connected to a different power source with a new power cord, the power supply is probably faulty.

If you are unable to resolve the problem, contact a customer service representative for instructions.

Statement 1072—Shock Hazard from Interconnections

Warning

Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if interconnections are made using uninsulated exposed metal contacts, conductors, or terminals. Avoid using such interconnection methods, unless the exposed metal parts are located within a restricted access location and users and service people who are authorized within the restricted access location are made aware of the hazard. A restricted access area can be accessed only through the use of a special tool, lock and key or other means of security.

Voltages kunnen elektrische schokken veroorzaken in PoE (Power over Ethernet)-circuits als er verbindingen worden gemaakt met blootliggende metalen contactpunten, geleiders of aansluitingspunten die niet zijn geïsoleerd. Gebruik dit type verbinding niet tenzij de blootliggende metalen onderdelen zich bevinden op een locatie met beperkte toegang en de gebruikers en onderhoudstechnici die toegang tot deze locatie hebben, op het gevaar worden gewezen. De locatie met beperkte toegang kan alleen worden geopend met speciaal gereedschap, slot en sleutel of een andere beveiligingsmethode.

Sisäisissä Ethernet (PoE) -virtapiireissä voi olla sähköiskun vaaran aiheuttavia jännitteitä, jos kytkentöihin käytetään eristämättömiä paljaita metalliliittimiä tai -johtimia. Vältä tällaisia kytkentöjä, elleivät paljaat metalliosat ole rajatussa paikassa. Ilmoita valtuutetuille käyttäjille ja huoltohenkilöille vaarasta. Rajattuun alueeseen pääsee käsiksi ainoastaan erityistyökalua, lukkoa ja avainta tai muuta turvallista menetelmää käyttämällä.

Les tensions existant sur les alimentations utilisant la technologie PoE (Power over Ethernet) peuvent constituer un risque d'électrocution si les interconnexions sont effectuées en utilisant des terminaux, conducteurs ou contacts métalliques exposés non isolés. Évitez d'utiliser de telles méthodes d'interconnexion à moins que les pièces métalliques exposées ne se trouvent dans un emplacement d'accès restreint et que les utilisateurs et les responsables du service autorisés dans cet emplacement d'accès restreint ne soient conscients du danger. Une zone d'accès restreint peut être accédée uniquement à l'aide d'une clé, d'un outil et d'un verrou spécial, ou d'autres moyens de sécurité.

Bei Power-over-Ethernet-(PoE-)Schaltkreisen besteht u.U. Stromschlaggefahr, wenn Verbindungen unter Verwendung nicht isolierter, freiliegender Metallkontakte, Leiter oder Anschlussklemmen hergestellt werden. Vermeiden Sie das Herstellen solcher Verbindungen, es sei denn, die freiliegenden Metallteile befinden sich an Orten mit beschränktem Zugang, und Personen, die Zugang dazu haben, sind ausdrücklich über diese Gefahr informiert worden. Ein Ort mit beschränktem Zugang ist nur mit Hilfe eines speziellen Werkzeugs, Schloss und Schlüssels oder anderen Sicherheitseinrichtungen zugänglich.

Nei circuiti con alimentazione via Ethernet (PoE) possono verificarsi pericoli di scosse elettriche se si creano connessioni con contatti metallici, conduttori o terminali scoperti. Evitare di utilizzare i metodi di connessione sopraelencati a meno che le parti metalliche esposte non si trovino in una zona riservata e gli utenti e il personale di assistenza, che sono autorizzati ad accedere nella suddetta zona, siano stati messi al corrente del pericolo. È possibile accedere alla zona riservata solamente utilizzando gli appositi elementi di sicurezza.

I strømkretser med PoE (Power over Ethernet) kan det være spenninger som kan utgjøre støtfare hvis det blir foretatt sammenkoblinger med uisolerte, eksponerte kontakter, ledere eller terminaler av metall. Unngå å bruke slike sammenkoblingsmetoder med mindre de eksponerte metalldelene er i et område med begrenset tilgang, og brukere og servicepersonell som har tilgang til det begrensede området, blir gjort oppmerksom på faren. Et område med begrenset tilgang kan bare åpnes ved hjelp av spesialverktøy, nøkkel eller andre sikkerhetstiltak.

Pode haver voltagens que representam perigo de choque em circuitos PoE (Power over Ethernet) se as interconexões forem feitas utilizando-se terminais, condutores ou contatos de metal exposto e sem isolamento. Evite utilizar tais métodos de interconexão a não ser que as partes de metal expostas estejam em um local de acesso restrito e os usuários e o pessoal de serviço com acesso autorizado a este local restrito estejam cientes do perigo. Uma área de acesso restrito só pode ser acessada com o uso de uma ferramenta, fechadura e chave especial ou de outros meios de segurança.

Puede haber voltajes con riesgo de shock en circuitos de alimentación sobre el cableado Ethernet (PoE), si para las interconexiones se utilizan contactos, conductores o terminales metálicos descubiertos. Evite tales métodos de interconexión, a menos que las partes metálicas descubiertas se encuentren en un lugar de acceso restringido y tanto los usuarios como el personal de servicios en dicho lugar sean conscientes de la existencia de tal riesgo. Sólo se puede tener acceso a una zona de acceso restringido mediante el uso de una herramienta especial, un candado y una llave u otros medios de seguridad.
