Cisco 12006 and Cisco 12406 Router Chassis Cable-Management Bracket Replacement Instructions


Product Number: ACS-GSR6-CCBLM=
Document Order Number: DOC-7816105=

The Cisco 12006 and Cisco 12406 Routers use a cable-management system to organize the network interface cables entering and exiting the line cards and route processor (RP). This document contains instructions to guide you through the steps to remove and replace the chassis cable-management bracket on the Cisco 12006 or Cisco 12406 Router.

These two router models are differentiated by the switching capacity of the switch fabric installed in the router:

Cisco 12006 Router—2.5-Gbps switch fabric

Cisco 12406 Router—10-Gbps switch fabric

Other than the switch fabric, these routers are identical in most respects. Any differences between the models are described in the appropriate locations. Unless otherwise noted, all information in this publication applies to both router models.

Tools and Equipment

To remove and install the chassis cable-management bracket, you need the following tools and equipment:

ESD-preventive strap

3/16-inch flat-blade screwdriver

Safety Guidelines

Before you perform any procedure in this publication, review the safety guidelines in this section to avoid injuring yourself or damaging the equipment. In addition, review the safety warnings listed in the Regulatory Compliance and Safety Information for the Cisco 12000 Series Router publication (Document Number 78-4347-xx) that accompanied your router before installing, configuring, or maintaining the router.

The following guidelines are for your safety and to protect equipment. The guidelines do not include all hazards. Be alert.

Safety with Equipment

Always disconnect all power cords and interface cables before moving the system.

Never assume that power is disconnected from a circuit; always check.

Keep tools and assembly components away from walkways and equipment rack aisles.

Do not work alone if potentially hazardous conditions exist.

Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.

Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.

Safety with Electricity

Before beginning any procedures requiring access to the interior of the router, locate the emergency power-off switch for the room in which you are working.

Disconnect all power and external cables before installing or removing a router.

Never assume that power has been disconnected from a circuit; always check.

Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.

Never install equipment that appears damaged.

Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.

If an electrical accident does occur, proceed as follows:

Use caution; do not become a victim yourself. Disconnect power to the router.

If possible, send another person to get medical aid; otherwise, assess the condition of the victim and then call for help.

Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.

In addition, observe the following guidelines when working with any equipment that is disconnected from a power source but still connected to telephone or network wiring:

Never install telephone wiring during a lightning storm.

Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.

Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.

Use caution when installing or modifying telephone lines.

Preventing Electrostatic Discharge Damage

Many router components can be damaged by static electricity. Some components can be damaged by voltages as low as 30V, while static voltages as high as 35,000V can be generated just by handling plastic or foam packing material, or by sliding assemblies across plastic and carpets. Not exercising the proper electrostatic discharge (ESD) precautions can result in intermittent or complete component failures. To minimize the potential for ESD damage, observe the following guidelines:

Always use an ESD-preventive antistatic wrist strap or ankle strap and ensure that it makes good skin contact.


Caution You should periodically check the resistance value of the ESD-preventive strap. The measurement should be between 1 and 10 megohms.

When removing or installing a component, make sure the equipment end of your antistatic strap leash is connected to one of the ESD connection sockets on the front of the chassis or to a bare metal surface on the chassis. (See Figure 3.) Avoid contact between the component and your clothing. The ESD-preventive wrist strap only protects the component from ESD voltages on the body; ESD voltages on your clothing can still cause component damage.

Always place a card component-side-up on an antistatic surface, in an antistatic card rack, or in a static shielding bag. If you are returning the item to the factory, immediately place it in a static shielding bag.

When installing a line card or route processor (RP), use the ejector levers to seat the card connectors in the backplane, then tighten both captive screws on the faceplate of the card. These screws prevent accidental removal, provide proper grounding for the router, and help to ensure that the card connector is seated in the backplane.

When removing line cards, clock and scheduler cards, switch fabric cards, or an RP, use the ejector levers to unseat the card connector from the backplane. Pull the metal card carrier out slowly, placing one hand along the bottom of the carrier to guide it straight out of the slot.

Handle line cards, clock and scheduler cards, switch fabric cards, or an RP by the metal card carrier edges only; avoid touching the board or any connector pins.

Removing and Installing the Cable-Management Bracket

When you face the front of the router chassis, the chassis cable-management bracket is installed on the left side. There are four captive screws that hold the bracket to the chassis frame. (See Figure 1.)

To remove and install the cable-management bracket, see Figure 1 and Figure 2 and follow these steps:


Step 1 Attach an ESD-preventive strap to your wrist and connect the leash to the chassis or to another grounded, bare metal surface.

Step 2 Open the rotating latches on the chassis cable-management bracket and carefully remove the line card and RP cables from the fingers. Try to keep the cables in groups so that you can reroute them on the replacement chassis cable-management bracket.

Step 3 Loosen the four captive screws with a flat-blade screwdriver and remove the chassis cable-management bracket from the chassis frame.

Step 4 Remove the replacement chassis cable-management bracket from the shipping carton.


Note The top of the cable-management bracket can be identified by the two captive screws that are recessed into the cable-management bracket frame.


Step 5 Orient the top of the cable-management bracket with the top left side of the chassis.

Step 6 Align the top two captive screws on the bracket with the threaded holes on the upper left side of the chassis.

Step 7 Tighten the top two captive screws with a flat-blade screwdriver.

Step 8 Use the same screwdriver to tighten the bottom two captive screws.


Routing Line Card and RP Cables

Line card and RP cables must be routed only between two fingers of the chassis cable-management bracket. (See Figure 2.) Never wrap cables around the fingers of the bracket. After you hold the cables between the fingers, close the rotating latch to secure the cables in the bracket. (See Figure 1.)

Keep the cables free of sharp bends, allow adequate strain relief, and avoid excessive bending of network interface cables; these conditions can degrade performance.

Line Card and RP Safety

When removing line cards, line card blanks, clock and scheduler cards, or switch fabric cards, remove each component entirely from the chassis and place it in an ESD-safe environment.

Do not allow the card or blank to rest partially inserted into the slots, as this will damage the electromagnetic interference (EMI) shielding on the RP or line card in the slot directly below.
