Safety Overview
Throughout this publication, safety warnings appear in procedures that can harm you if performed incorrectly. A warning symbol precedes each warning statement.
Metro Supervisor Engine
This section describes the Catalyst 4500 E-Series Metro Supervisor Engine 6-E (ME-X45-SUP6-E). See Figure 1. This supervisor engine provides switching control for all network interfaces, and provides 10-Gigabit Ethernet interfaces for uplinks. It works in combination with the ME-X4624-SFP-E 24-port Hierarchal-QoS Gigabit Ethernet switching module to provide Hierarchical Quality of Service, as well as working with other E-series switching modules and Catalyst 4500 series classic switching modules. Software features include split horizon, VLAN translation, CFM, and RPR redundancy Address Flexible Ethernet Service, VLAN and MAC address scaling, and Ethernet Manageability over an IEEE Bridging infrastructure.
The Metro Supervisor Engine is supported in the Catalyst 4503, 4506, 4507R, 4510R, 4503-E, 4506-E, 4507R-E, and 4510R-E switches. On the Catalyst 4503, 4503-E, 4506, and 4506-E switches, you can install the Metro Supervisor Engine only in slot 1. On the Catalyst 4507R or 4510R switch, you install the primary supervisor engine in slot 1, and you can install an optional redundant supervisor engine in slot 2. On the Catalyst 4507R-E switch, you install the primary supervisor engine in slot 3, and you can install an optional redundant supervisor engine in slot 4. On the Catalyst 4510R-E switch, you install the primary supervisor engine in slot 5, and you can install an optional redundant supervisor engine in slot 6. The supervisors in a redundant system must be of the same type.
The supervisor engine is hot swappable, but packets are not forwarded when the last supervisor engine has been removed from the switch. When a supervisor engine is reinserted into the switch, the supervisor reboots.

Fan Tray
The Metro Supervisor Engine requires an upgraded fan tray in the Catalyst 4503, 4506, 4507R, and 4510R. Existing fan trays in those systems do not provide sufficient cooling for this supervisor engine and lead to system shutdowns until the supervisor engine cools or the fan tray is replaced. The fan tray in Catalyst 4503-E, 4506-E, 4507R-E, and 4510R-E switches does not require an upgrade.

10-Gigabit Ethernet Uplink Ports
The 10-Gigabit Ethernet uplink ports operate in full-duplex mode only. These ports use the hot-swappable X2 optical transceivers. The X2s have SC connectors to interface with multimode fiber (MMF) and single-mode fiber (SMF) cable. For further information on X2s, see the "X2 Handling Guidelines and Installation" section.
When two Metro Supervisor Engines are present in a Catalyst 4507R, Catalyst 4507R-E, Catalyst 4510R or Catalyst 4510R-E switch, one X2 uplink is active on both the primary (active) and secondary (standby) supervisor engines by default, or two uplinks are active in a nonredundant configuration.
Gigabit Ethernet SFP Uplink Ports
If you want to use SFPs instead of X2s as your uplink transceivers, you can use Cisco TwinGig converter modules in the X2 slots. 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
Ethernet Management Port
The Ethernet management port is used (in ROMMON mode only) to recover a switch software image that has been corrupted or destroyed due to a network catastrophe. This port is not active while the switch is operating normally.
Console Port
The Catalyst 4500 E-Series Metro Supervisor Engine 6-E console port has an EIA/TIA-232 RJ-45 connector. The console port allows you to perform the following functions:
•Configure the switch from the CLI
•Monitor network statistics and errors
•Configure SNMP agent parameters
Note EIA/TIA-232 was known as recommended standard RS-232 before its acceptance as a standard by the Electronic Industries Alliance (EIA) and Telecommunications Industry Association (TIA).
Reset Button
The Reset button restarts the switch.
Note Use a paper clip or other small, pointed object to press the Reset button.
Compact Flash Port

ME-X4624-SFP-E
The Metro supervisor engine works with the ME-X4624-SFP-E 24-port Hierarchal-QoS Gigabit Ethernet switching module.This switching module performs Level 3 policing on traffic before forwarding packets to the supervisor engine, and therefore is integral to the Metro Ethernet functionality of the switch. The 24-port H-QoS Gigabit Ethernet switching module only works in an E-series chassis (Catalyst 4503-E, 4506-E, 4507R-E, 4510R-E). The module (see Figure 2) has the following specifications:

Removing the Supervisor Engine
All Catalyst 4500 series switches support hot swapping, which lets you install, remove, replace, and rearrange supervisor engines and switching modules without powering the system off. When the system detects that a switching module has been installed or removed, it runs diagnostic and discovery routines automatically, acknowledges the presence or absence of the module, and resumes system operation with no operator intervention.
This section contains the following subsections:
•Installing the Supervisor Engine
•Removing the Supervisor Engine
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030
Warning Ultimate disposal of this product should be handled according to all national laws and regulations. Statement 1040Required Tools
You will need these tools to install a supervisor engine in a Catalyst 4500 series switch:
•Number 1 and number 2 Phillips screwdrivers for the captive installation screws on most modules
•3/16-in. flat-blade screwdriver for the captive installation screws on other modules
•Antistatic mat or antistatic foam
•Wrist strap or other grounding device
Note Whenever you handle supervisor engines, use a wrist strap or other grounding device to prevent electrostatic discharge (ESD) damage.
Preventing Electrostatic Discharge Damage
ESD damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Port adapters and processor modules consist of printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, use a preventive antistatic strap during handling.
Following are guidelines for preventing ESD damage:
•Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.
•Connect the equipment end of the strap to an unfinished chassis surface.
•When installing a component, use any available ejector levers or captive installation screws to properly seat the bus connectors in the backplane or midplane. These devices prevent accidental removal, provide proper grounding for the system, and help to ensure that bus connectors are properly seated.
•When removing a component, use any available ejector levers or captive installation screws to release the bus connectors from the backplane or midplane.
•Handle carriers by available handles or edges only; avoid touching the printed circuit boards or connectors.
•Place a removed component board-side-up on an antistatic surface or in a static shielding container. If you plan to return the component to the factory, immediately place it in a static shielding container.
•Avoid contact between the printed circuit boards and clothing. The wrist strap only protects components from ESD voltages on the body; ESD voltages on clothing can still cause damage.
•Never attempt to remove the printed circuit board from the metal carrier.
Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohm (Mohm).
Installing the Supervisor Engine
Catalyst 4500 series and Catalyst 4500 E-Series switches have horizontal chassis slots that are numbered from top to bottom. On the Catalyst 4503, 4503-E, Catalyst 4506, and 4506-E switches, you can install the supervisor engine only in slot 1. On the Catalyst 4507R or 4510R switch, you install the primary supervisor engine in slot 1, and you can install an optional redundant supervisor engine in slot 2. On the Catalyst 4507R-E switch, you install the primary supervisor engine in slot 3, and you can install an optional redundant supervisor engine in slot 4. On the Catalyst 4510R-E switch, you install the primary supervisor engine in slot 5, and you can install an optional redundant supervisor engine in slot 6. The supervisors in a redundant system must be of the same type.
Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034
Caution To prevent ESD damage, handle supervisor engines by the carrier edges only.
Tip Due to the power requirements of the ME-X45-SUP6-E, some configurations may require two power supplies in combined mode or a higher capacity power supply. Redundant power supplies or a single power supply configuration would not be not supported in these cases. To verify the power needs of your switch's configuration, refer to the Cisco Power Calculator at http://tools.cisco.com/cpc/
To install a supervisor engine in a Catalyst 4500 E-Series switch, follow this procedure:
Step 1 Take the necessary precautions to prevent ESD damage as described in the installation guide for your switch.
Step 2 Ensure that you have enough clearance to accommodate any interface equipment that you will connect directly to the supervisor engine ports.
Step 3 Loosen the captive installation screws that secure the switching-module filler plate or the existing supervisor engine (whichever is present) and remove it.
Step 4 Remove the supervisor engine filler plate or the existing supervisor engine from slot 1. If a switching module filler plate was installed, save it for future use. If you are removing an existing supervisor engine, see the "Removing the Supervisor Engine" section.
Step 5 To install the new supervisor engine, grasp the switching module front panel with one hand and place your other hand under the carrier to support the supervisor engine, as shown in Figure 3. Do not touch the printed circuit boards or connector pins.
Step 6 Align the edges of the supervisor engine carrier with the slot guides on the sides of the switch chassis, as shown in Figure 3.
Figure 3 Installing the Supervisor Engine in the Chassis (Catalyst 4506-E Shown)
Step 7 Pivot the two module ejector levers out and away from the faceplate.
Step 8 Carefully slide the supervisor engine into the slot until the notches on both ejector levers engage the chassis sides.
Step 9 Using the thumb and forefinger of each hand, simultaneously pivot in both ejector levers to fully seat the supervisor engine in the backplane connector.
Caution Always use the ejector levers when installing or removing a supervisor engine. A supervisor engine that is partially seated in the backplane will not function correctly.
Step 10 Use a screwdriver to tighten the captive installation screws on each end of the supervisor engine faceplate.
To check the status of the module, follow these steps:
Step 1 Ensure that the LED labeled Status is green (module operational).
Step 2 When the switch is online, enter the show module command. Verify that the system acknowledges the new module and that the module's status is good.
Step 3 If the module is not operational, reseat it. If the module is still not operational, contact your customer service representative.
Removing the Supervisor Engine
Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051
Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034
Caution To prevent ESD damage, handle supervisor engines by the carrier edges only.
To remove a supervisor engine from a Catalyst 4500 E-series switch, follow this procedure:
Step 1 Disconnect any network interface cables attached to the ports on the supervisor engine that you intend to remove.
Step 2 Loosen the captive installation screws (see Figure 4).
Figure 4 Captive Installation Screws and Ejector Levers
Step 3 Grasp the left and right ejector levers and simultaneously pivot the levers outward to release the supervisor engine from the backplane connector. Figure 4 shows a close-up of the right ejector lever.
Step 4 Grasp the front panel of the supervisor engine with one hand and place your other hand under the carrier to support and guide it out of the slot. Do not touch the printed circuit boards or connector pins.
Step 5 Carefully pull the supervisor engine straight out of the slot, keeping your other hand under the carrier to guide it.
Step 6 Place the supervisor engine on an antistatic mat or antistatic foam, or immediately install it in another slot.
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 1029Step 7 If the slot is to remain empty, install a switching-module filler plate (part number 800-00292-01).
Attaching Module Interface Cables
Figure 5 and Figure 6 show the connector types used to attach interface cables to the supervisor engine.
Figure 5 RJ-45 Connector
Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables. Statement 1021
Note Always keep caps and plugs on the fiber-optic connectors on the cable and the switch when they are not in use.
Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051Figure 6 SC-Type Fiber-Optic Connector
SC Connector
The SC connector, shown in Figure 7, is used to connect fiber-optic module ports or transceivers with the external SMF or MMF network.
Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051
Note Make sure that the optical connectors are clean before making the connections. Contaminated connectors can damage the fiber and cause data errors.
Figure 7 SC Fiber-Optic Connector
Always insert the network connector completely into the socket. A secure connection is especially important when you are establishing a connection between a module and a long distance (1.24 miles) (2 km) network or a module and a suspected highly attenuated network. If the link LED does not light, try removing the network cable plug and reinserting it firmly into the module socket. It is possible that dirt or skin oils have accumulated on the plug faceplate (around the optical-fiber openings), generating significant attenuation and reducing the optical power levels below threshold levels so that a link cannot be made.
Caution Use extreme care when removing or installing connectors so that you do not damage the connector housing or scratch the end-face surface of the fiber. Always install protective covers on unused or disconnected components to prevent contamination. Always clean fiber connectors before installing them.
LC Connector
Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051The LC fiber-optic connector, shown in Figure 8, is a small form-factor fiber-optic connector that provides high-density fiber connectivity. The LC connector can be used with either MMF cable or SMF cable. The LC connector uses a latching clip mechanism that is similar to the one used on the RJ-45 copper connector.
Note Make sure that the optical connectors are clean before making the connections. Contaminated connectors can damage the fiber and cause data errors.

Configuring Your Supervisor Engine
For information and commands to configure your supervisor engine, refer to the software configuration guide for your switch.
X2 Handling Guidelines and Installation
An X2 transceiver (see Figure 9) is a hot swappable input/output device that plugs into the 10 Gigabit Ethernet port of the supervisor engine and links the supervisor engine with a fiber-optic network. X2 transceivers are online swappable.
You may also use Cisco TwinGig converter modules in these ports. Installation documentation for Cisco TwinGig converter modules can be found at:

Warning Use of controls, adjustments, or performing procedures other than those specified may result in hazardous radiation exposure. Statement 1057For supported X2 transceiver media types, refer to the release note for your switch software or to:
http://www.cisco.com/en/US/docs/interfaces_modules/transceiver_modules/compatibility/matrix/OL_6974.html
Caution Because of interoperability issues, Cisco does not support X2s purchased from third-party vendors.
Cisco 1000BASE-LX/LH interfaces fully comply with the IEEE 802.3z 1000BASE-LX standard. However, their higher optical quality allows them to reach 10 km over SMF cable instead of the 5 km specified in the standard.
If an LR X2 designed for operation on an SMF cable is directly coupled to an MMF cable, an effect known as Differential Mode Delay (DMD) might occur. See the Catalyst 4000 Family Module Installation Guide for more information.
This section describes the following topics:
•Installing the 10-Gigabit Ethernet X2 Transceiver
•Installing the 10-Gigabit Ethernet X2 Transceiver
•X2 Transceiver Maintenance Guidelines
Installing the 10-Gigabit Ethernet X2 Transceiver
Caution The 10-Gigabit Ethernet X2 transceiver is a static-sensitive device. Always use an ESD wrist strap or similar individual grounding device when handling X2 transceivers or coming into contact with modules.
Note Before removing the dust plugs and making any optical connections, observe the following guidelines:
•Always keep the protective dust plugs on the unplugged fiber-optic cable connectors and the transceiver optical bores until you are ready to make a connection.
•Always inspect and clean the SC connector end-faces just before making any connections. Refer to the Tip on page 23 for a pointer to a fiber-optic inspection and cleaning white paper.
•Always grasp the SC connector housing to plug or unplug a fiber-optic cable.
To install a 10-Gigabit Ethernet X2 transceiver, follow these steps:
Step 1 Using a small flat-blade screwdriver, carefully pry the X2 transceiver port cover off of the module faceplate.
Use the two arrows on the port cover as guides for inserting the screwdriver blade. Save the port cover for future use.
Step 2 Remove the 10-Gigabit Ethernet X2 transceiver from its protective packaging.
Step 3 Check the label on the 10-Gigabit Ethernet X2 transceiver to verify that the 10-Gigabit Ethernet X2 transceiver is the correct model for your network.
Step 4 Grip the sides of the 10-Gigabit Ethernet X2 transceiver sleeve with your thumb and forefinger, and insert the 10-Gigabit Ethernet X2 transceiver into the X2 socket on the module front panel. You will hear a click when the X2 transceiver is approximately 90 percent installed. Continue sliding the X2 transceiver into the socket until you hear a second click. The X2 transceiver connector is now mated to the socket connector. Verify that the X2 transceiver EMI gasket is in contact with the module faceplate. (See Figure 10.)
Tip With some X2 transceivers you might need to pull out the latching sleeve as you slide the X2 transceiver into the socket. When the EMI gasket makes contact with the module faceplate, slide the latching sleeve in to secure the X2 transceiver in the socket.
Figure 10 Installing the 10-Gigabit Ethernet X2 Transceiver
Note 10-Gigabit Ethernet X2 transceivers are keyed to prevent incorrect insertion.
Step 5 Remove the dust plugs from the network interface cable SC connectors.
Save the dust plugs for future use.
Step 6 Inspect and clean the SC connector's fiber-optic end-faces. Refer to the Tip below for a pointer to a fiber-optic inspection and cleaning white paper.

Figure 11 Removing the 10-Gigabit Ethernet X2 Transceiver
Step 3 Slide the 10-Gigabit Ethernet X2 transceiver out of the socket and immediately place it in an antistatic bag.
Step 4 Reinstall the socket cover if you are not installing an X2 transceiver in the empty socket.
a. Position the socket cover in front of the socket opening.
b. Snap the socket cover in place.
X2 Transceiver Maintenance Guidelines
To properly maintain X2 transceivers, follow these guidelines:
•To prevent ESD damage, follow normal handling procedures.
•When the transceiver is stored or when a fiber-optic cable is not plugged in, always keep plugs in the optical bores.
•The most common source of contaminants in the optical bores is debris picked up on the ferrules of the optical connectors. Use an alcohol swab or Kim-Wipe to clean the ferrules of the optical connector.
Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051SFP Guidelines
The Metro Supervisor Engine has two X2 ports that can support Cisco TwinGig modules providing two SFP connections to other network devices. A total of four SFPs is possible.
You can use any combination of supported SFP modules. Use only Cisco SFP modules on your Cisco device. Each SFP module has an internal serial EEPROM that is encoded with security information. This encoding provides a way for Cisco to identify and validate that the SFP module meets the requirements for the device.
For supported SFP transceiver media types, refer to:
http://www.cisco.com/en/US/docs/interfaces_modules/transceiver_modules/compatibility/matrix/OL_6981.html
http://www.cisco.com/en/US/docs/interfaces_modules/transceiver_modules/compatibility/matrix/OL632702.html
Cisco 1000BASE-LX/LH interfaces fully comply with the IEEE 802.3z 1000BASE-LX standard. However, their higher optical quality enables them to reach 10 km over SMF cable instead of the 5 km specified in the standard.
If an LX/LH SFP designed for operation on an SMF cable is directly coupled to an MMF cable, an effect known as Differential Mode Delay (DMD) might occur. See the Catalyst 4500 Series Module Installation Guide for more information.
This section describes the following topics:
Fiber-Optic SFP Modules
Some fiber-optic SFP modules use LC-type connectors, as shown in Figure 12.
Caution Protect your fiber-optic SFP modules by inserting clean dust plugs into the SFP modules after you remove the cables. Be sure to clean the optic surfaces of the fiber-optic cables with a soft antistatic cloth before you reconnect them to another SFP module. Avoid getting dust and other contaminants into the optical bores, as the optics do not work correctly when obstructed with dust.
Figure 12 LC Fiber-Optic SFP Module
SFPs provide duplex single-mode and multimode connections in supported devices. For cable specifications for fiber-optic SFP module ports, refer to:
http://www.cisco.com/en/US/docs/interfaces_modules/transceiver_modules/installation/note/78_15160.html#wp124692
Note When using shorter distances of single-mode fiber cable, you might need to insert an inline optical attenuator in the link to avoid overloading the receiver.
When the fiber-optic cable span is less than 15.43 miles (25 km), you should insert a 5-decibel (dB) or 10-dB inline optical attenuator between the fiber-optic cable plant and the receiving port on the 1000BASE-ZX SFP module at each end of the link.
Fiber-optic SFP modules also use MT-RJ connectors, as shown in Figure 13.

1000BASE-T SFP Modules
Copper 1000BASE-T SFP modules as shown in Figure 14 use RJ-45 connectors.
Figure 14 1000BASE-T Copper SFP Module
1000BASE-T copper SFP modules used with the Catalyst 4500 E-Series Metro Supervisor Engine 6-E operate only in 1000BASE-T mode, or at 1000 Mb/s. Copper 1000BASE-T SFP modules use standard four twisted-pair, Category 5 cable at lengths up to 328.08 feet (100 meters).
CWDM SFPs
You can connect the CWDM SFPs to CWDM passive optical system optical add/drop multiplexer (OADM) or multiplexer/demultiplexer plug-in modules using single-mode fiber-optic cables with standard SC connectors. Figure 15 shows a CWDM SFP with the optical port dust plug removed. Figure 6 shows an SC-type connector.

Fiber-Optic Connectors
Fiber-optic cable connectors can be damaged by improper cleaning and connection procedures. Dirty or damaged fiber-optic connectors can result in communication that is not repeatable or inaccurate.
Fiber-optic connectors differ from electrical or microwave connectors. In a fiber-optic system, light is transmitted through an extremely small fiber core. Because fiber cores are often 62.5 microns or less in diameter, and dust particles range from a tenth of a micron to several microns in diameter, dust and any contamination at the end of the fiber core can degrade the performance of the connector interface where the two cores meet. Therefore, the connector must be precisely aligned, and the connector interface must be absolutely free of trapped foreign material.
Connector loss, or insertion loss, is a critical performance characteristic of a fiber-optic connector. Return loss is also an important factor. Return loss specifies the amount of reflected light; the lower the reflection, the better the connection. The best physical contact connectors have return losses greater than -40 dB, although -20 to -30 dB is more common.
The connection quality depends on two factors: the type of connector and the proper cleaning and connection techniques. Dirty fiber connectors are a common source of light loss. Keep the connectors clean at all times, and keep the dust covers installed when the connectors are not in use.
Before installing any type of cable or connector, use a lint-free alcohol pad from a cleaning kit to clean the ferrule, the protective white tube around the fiber, and the end-face surface of the fiber.
As a general rule, whenever there is a significant, unexplained loss of light, clean the connectors.
Caution Use extreme care when removing or installing connectors so that you do not damage the connector housing or scratch the end-face surface of the fiber. Always install protective covers on unused or disconnected components to prevent contamination. Always clean fiber connectors before installing them.
To clean the optical connectors, use a CLETOP cassette cleaner (type A for SC connectors or type B for MT-RJ connectors) and follow the product directions. If a CLETOP cassette cleaner is not available, follow these steps:
Step 1 Use a lint-free tissue soaked in 99 percent pure isopropyl alcohol to gently wipe the faceplate. Wait five seconds for the surfaces to dry, and repeat.
Step 2 Remove any residual dust from the faceplate with clean, dry, oil-free compressed air.
Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051Step 3 Use a magnifying glass or inspection microscope to inspect the ferrule at an angle. Do not look directly into the aperture. Repeat the process if any contamination is detected.
The connectors used inside the system have been cleaned by the manufacturer and connected to the adapters in the proper manner. The operation of the system should be error free if the customer provides clean connectors on the application side, follows the previous directions, and follows these guidelines:
•Clean the connectors using either a CLETOP cassette cleaner (Type A for SC connectors and Type B for MT-RJ connectors) or lens tissues before connecting to the adapters. Use pure alcohol to remove contamination.
•Do not clean the inside of the connector adapters.
•Do not use force or quick movements when connecting the fiber-optic connectors in the adapters.
•Cover the connectors and adapters to keep the inside of the adapters or the surface of the connectors from getting dirty when you are not using the connectors or while you are cleaning the chassis.
