Chassis Front Covers Overview

The Cisco 12016, Cisco 12416, and Cisco 12816 Routers are equipped with front covers over the power shelf and upper blower module, the lower blower module, and each of the integral card cages in the chassis. (See Figure 1.) The front covers protect the system and present a consistent product appearance.


Note Recently released routers have a bezel extender installed on the front covers to bring the cover out an additional 2 inches (50.8 mm) to allow more room for cables. If your chassis does not have these extenders and you want to purchase them, contact Cisco sales. (See the "Installing the Bezel Extender" section if you are self-installing the bezel extender.)

Bezel Extender Overview

Recent releases of the Cisco 12016, Cisco 12416, and Cisco 12816 Routers include a bezel extender that provides additional room within the line card cages to support advanced cabling configurations. If you have obtained the bezel extender separately from the router, review this section and the "Installing the Bezel Extender" section.


Note The bezel extender is designed for the line card cages only.


The bezel extender (Figure 2, item 4) allows you to extend the bezel (Figure 2, item 1) 2 inches
(50.8 mm) from the front of the chassis to prevent the possibility of compromising the bend radius of your cables.

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 Internet Router publication 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 walk areas.

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 Chassis Front Covers

The chassis front covers for the power shelf and upper blower module, upper card cage, lower card cage, and lower blower module are fastened to the chassis by ball studs that insert into sockets on the front of the chassis. These front covers are referred to as snap-on front covers.

The partial front cover on the air filter door is fastened to the air filter door by four screws inserted from the back side of the air filter door. You must open the air filter door to remove the partial front cover. This partial front cover is referred to as the air filter door front cover.

Procedures for removing and installing the chassis front covers are described in the following sections:

Removing and Installing the Snap-On Chassis Front Cover

Removing and Installing the Air Filter Door Front Cover

You can perform these procedures while the router remains powered up.

Removing and Installing the Snap-On Chassis Front Cover

This section provides two procedures:

Removing the Snap-on Front Cover

Installing the Snap-on Front Cover

Removing the Snap-on Front Cover

To remove one of the snap-on front covers (for the power shelf and upper blower module, upper card cage, lower card cage, and lower blower module), follow these steps:


Step 1 Starting with the cover over the power shelf and upper blower module, observe the appearance and position of each of the four snap-on front covers on the router. (See Figure 1.)

Step 2 Identify the front cover to be removed.

Step 3 Grasp the outside edges of the front cover and pull it straight out to detach the front cover from the chassis. (See Figure 4.)

Figure 4 Removing a Snap-on Front Cover (Upper Blower Module Front Cover Shown)

Each of the snap-on front covers is equipped with a set of four ball studs that insert into sockets on the front of the chassis to secure the front cover.

Step 4 Set the front cover safely aside.

Repeat Step 3 and Step 4 for the remaining snap-on front covers, if required.


Installing the Snap-on Front Cover

To install a snap-on front cover, use Figure 1 as a reference and follow these steps:


Step 1 Hold the replacement front cover by its outside edges and align the ball studs with the sockets on the front of the chassis.

Step 2 Push the front cover into the ball stud sockets until all four ball studs snap into their sockets and the front cover is flush with the front of the chassis.

Repeat Step 1 and Step 2 for the remaining snap-on front covers, if required.


Removing and Installing the Air Filter Door Front Cover

This section provides two procedures:

Removing the Air Filter Door Front Cover

Installing the Replacement Air Filter Door Front Cover

Removing the Air Filter Door Front Cover

To remove the air filter door front cover, follow these steps:


Step 1 Attach an ESD-preventive wrist strap to your wrist and connect the leash 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.)

Step 2 Open the air filter door. Use Figure 5 as a reference and follow the steps outlined below:

Figure 5 Opening the Air Filter Door

Step 3 Loosen the two captive screws on each side of the air filter door.

Step 4 Grasp the sides of the air filter door front cover and carefully swing the door out and down, away from the switch fabric card cage.

The air filter door is attached to the chassis by a pair of spring-loaded arms on either side of the door. When the door is fully extended away from the fabric card cage, it hangs down in front of the lower card cage.


Caution On routers with the bezel extender kit installed on the line card and RP card cage front covers, you must remove the extended front cover from the lower line card and RP card cage before attempting to open the air filter door. When the extended front cover is mounted on the chassis, the air filter door does not have adequate free space to open completely.


Caution Be especially careful not to damage the honeycomb screen on the back of the air filter door and on the inside of the switch fabric card cage. Damaging the honeycomb screen can restrict the air flow and cause overheating in the router. It can also diminish EMI protection.

Step 5 Using the Phillips screwdriver, loosen and remove the four screws that fasten the partial front cover to the air filter door. (See Figure 6.) Set the four screws safely aside; you will need them to install the replacement front cover.

Figure 6 Removing the Air Filter Door Front Cover

Step 6 Set the air filter door front cover safely aside.

Step 7 If you are not immediately replacing the air filter door front cover, close and fasten the air filter door to minimize the amount of dust drawn into the card cages:

a. Grasp the sides of the air filter door and pivot it up so that it is aligned with the opening of the switch fabric card cage, and the four guide pins are inserted in the corresponding holes on each side of the switch fabric card cage.


Caution All four sides of the air filter door are lined with EMI-preventive gaskets consisting of many raised, conductive contacts. Align and seat the door carefully to avoid damaging the EMI-preventive gasket contacts. A damaged gasket can result in reduced EMI performance.

b. Push the air filter door until it is seated in the opening of the switch fabric card cage and tighten the four captive screws.


Installing the Replacement Air Filter Door Front Cover

To install the replacement front cover on the air filter door, follow these steps:


Step 1 Attach an ESD-preventive wrist strap to your wrist and connect the leash 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.)

Step 2 If you have not already done so, open the air filter door on the front of the chassis. (See Figure 5.)

Step 3 Loosen the two captive screws on each side of the air filter door.

Step 4 Grasp the sides of the air filter door and carefully swing the door out and down, away from the switch fabric card cage.


Caution On routers with the bezel extender kit installed on the line card and RP card cage front covers, you must remove the extended front cover from the lower line card and RP card cage before attempting to open the air filter door. When the extended front cover is mounted on the chassis, the air filter door does not have adequate free space to open completely.


Caution Be especially careful not to damage the honeycomb screen on the back of the air filter door and on the inside of the switch fabric card cage. Damaging the honeycomb screen can restrict the airflow and cause overheating in the router. It can also diminish EMI protection.

Step 5 Hold the replacement front cover by its outside edges and align the screw holes in the front cover with the holes on the air filter door.

Step 6 Insert the four screws that you removed earlier and use the Phillips screwdriver to tighten the four screws. (See Figure 6.)


Caution To avoid damaging the screws or the threaded inserts in the front cover, do not overtighten the screws.

Step 7 Close the air filter door by grasping the sides of the air filter door front cover and pivoting the air filter door up so that it is aligned with the opening of the switch fabric card cage, and the four guide pins are inserted in the corresponding holes on each side of the switch fabric card cage. (See Figure 7.)

Figure 7 Closing the Air Filter Door


Caution All four sides of the air filter door are lined with EMI-preventive gaskets consisting of many raised, conductive contacts. Align and seat the door carefully to avoid damaging the EMI-preventive gasket contacts. A damaged gasket can result in reduced EMI performance.

Step 8 Push the air filter door until it is seated in the opening of the switch fabric card cage and tighten the four captive screws.



Caution The air filter door must be closed and secured at all times to maintain correct EMI performance.

Installing the Bezel Extender

To install the bezel extender, follow these steps:


Step 1 Remove the front cover from the chassis. See the "Removing and Installing the Chassis Front Covers" section.

Step 2 Using a wrench, remove the four ball studs from the chassis front cover. (See Figure 8, item 3.)

Step 3 Safely set aside the front cover and ball studs.

Step 4 Using a wrench, attach the four ball studs to the bezel extenders (two ball studs for each bezel extender).


Note The size of each bezel extender part differs slightly. If the extender does not align properly, try the other bezel extender part to obtain the proper alignment.


Step 5 Align the screw holes in the front cover with the holes on one of the bezel extenders.

Step 6 Insert the two screws and use a wrench to attach the bezel extender to one side of the chassis front cover. (See Figure 8, item 2.)
