This figure lists the steps to install Cisco NCS 5700 series fixed-port chassis and its components and prepare the system for operation. Use this workflow as a reference to ensure that all components are properly installed in the correct order. For information about a step, see the respective section of this installation guide.

Before you perform any procedure in this document, review the safety guidelines in this section to avoid injuring yourself or damaging the equipment. The following guidelines are for your safety and to protect equipment. Because the guidelines do not include all hazards, be constantly alert.

• Keep the work area clear, smoke and dust-free during and after installation. Do not allow dirt or debris to enter into any laser-based components.

• Do not wear loose clothing, jewelry, or other items that could get caught in the router or other associated components.

• Cisco equipment operates safely when used in accordance with its specifications and product-usage instructions.

• Be sure to power down a fixed configuration PDU or modular configuration power shelf before removing it from the chassis.

• If potentially hazardous conditions exist, do not work alone.

• Take care when connecting multiple units to the supply circuit so that wiring is not overloaded.

• This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain about whether suitable grounding is available.

• To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the handles on modules (such as power supplies, fans, or cards); these types of handles are not designed to support the weight of the unit.

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

• When installing or replacing the unit, the ground connection must always be made first and disconnected last.

• The rack stabilizing mechanism must be in place, or the rack must be bolted to the floor before you slide the unit out for servicing. Failure to stabilize the rack may cause the rack to tip over.

Warning

Statement 1051—Laser Radiation Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments.

The following are NEBS GR-1089-CORE cautions, regulatory compliance statements, and requirements:

• The intra-building port(s) of the equipment or subassembly must use shielded intra-building cabling/wiring that is grounded at both ends.

Caution

The intra-building port(s) of the equipment or subassembly is suitable for connection to intra-building or unexposed wiring or cabling only. The intra-building port(s) of the equipment or subassembly must not be metallically connected to interfaces which connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE) and require isolation from the exposed OSP cabling. The addition of primary protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.

• Products that have AC power ports that are intended for deployments where an external Surge Protective Device (SPD) is utilized at the AC power service equipment (see definition in National Electric Code).

• This product is designed for a Common Bonding Network (CBN) installation.

• This product can be installed in network telecommunication facilities or locations where the National Electric Code applies.

• An electrical conducting path shall exist between the product chassis and the metal surface of the enclosure or rack in which it is mounted or to a grounding conductor. Electrical continuity shall be provided by using thread-forming type mounting screws that remove any paint or nonconductive coatings and establish a metal-to-metal contact. Any paint or other nonconductive coatings shall be removed on the surfaces between the mounting hardware and the enclosure or rack. The surfaces shall be cleaned and an antioxidant applied before installation.

• The DC return connection to this system should remain isolated from the system frame and chassis (DC-I).

• The nominal DC operating voltage -48 VDC.

Before installing the chassis, verify that these guidelines are met:

• Site is properly prepared so that there is sufficient room for installation and maintenance. For specifications on the clearances required for chassis installation, see Clearance Requirements.

• Operating environment is within the ranges listed in table Environmental properties on the Cisco Network Convergence System 5700 Series: NCS-57B1 Fixed Chassis Data Sheet

  If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the chassis in the rack.

• Chassis is mounted at the bottom of the rack if it is the only unit in the rack.

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

• Airflow around the chassis and through the vents is unrestricted.

• Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting fixtures. Make sure that the cabling is safely away from other devices that might damage the cables.

• For cable requirements for optical module connections, see the Transceiver and Cable Specifications section. Each port must match the wave-length specifications on the other end of the cable, and the cable must not exceed the maximum cable length.

The fixed-port chassis requires front-to-back airflow. Leave at least 6.0 in. (15.24 cm) front and rear clearance for air intake/exhaust. Leave an additional 6.0 inches (15.24 cm) rear clearance for removal and installation of power supplies and fan modules.

1	Chassis	4	6.0 inches (15.24 cm) rear clearance for air intake/exhaust.
2	6.0 inches (15.24 cm) front clearance for air intake/exhaust.	5	Additional 6.0 inches (15.24 cm) rear clearance for removal and installation of power supplies and fan modules. Note   The NCS-57C3-MOD power supplies are installed from the front of the chassis; therefore, additional rear clearance is not required for NCS-57C3-MOD chassis.
3	Chassis depth: NCS-57B1: 23.6 in. (59.944 cm) NCS-57C3-MOD: 12.55 in. (31.88 cm) NCS-57C1: 19.68 in. (50.00 cm) NCS-57D2: 23.62 in. (59.99 cm)

Note

The temperatures are measured at the air inlet to the equipment. The temperatures are valid at sea level. The maximum allowable temperatures are reduced at higher altitudes. Altitude derating 1°C for every 300m. In case of a single fan failure, the maximum allowable temperature will be less than specified. In case the air filter is clogged, the temperature alarm may be raised at temperatures below the listed temperatures.

Obtain these necessary tools and equipment for installing the chassis:

• Number 1 and number 2 Phillips screwdrivers with torque capability to rack-mount the chassis

• 3/16-inch flat-blade screwdriver

• Tape measure and level

• ESD wrist strap or other grounding device

• Antistatic mat or antistatic foam

• A Torx T15 screwdriver, or the Torx T15 key to install adapters

• Grounding cable (6 AWG recommended), sized according to local and national installation requirements; the required length depends on the proximity of the switch to proper grounding facilities

• Ground lug (1)

• Crimping tool large enough to accommodate the girth of the lug

• Wire-stripping tool

• (ANSI) Pair of 19-inch mounting brackets

• M4 screws to fix brackets (16)

• M4 screws to fix ground lug (2)

The following table contains the accessory kit PIDs and the items present in the accessory kits of the fixed port routers. The rack mount kit present in the accessory kit contains the screws and brackets required for installation.

This section illustrates how the building that houses the chassis must be properly grounded to the earth ground.

Note	This image is only for representational purposes. Your grounding requirement depends on your building.

This section illustrates how to prepare yourself before removing the chassis from the sealed antistatic bag. The figures show how to cuff the ESD strap around the wrist and the ground cord that connects the cuff to the ground. ESD wrist straps are the primary means of controlling static charge on personnel.
