Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage to circuit boards can occur if they are handled improperly. Such
mishandling can result in intermittent or complete failures of the board.
When handling circuit boards, observe the following guidelines to prevent ESD damage.

Removing the Cable Management Brackets
•
Always use an ESD-preventive ankle or wrist strap and ensure that the strap makes adequate contact
with your skin.
•
Attach an ESD-preventive strap to your wrist or ankle and to the chassis; or to a bare metal surface.
See Figure 1.
•
The ankle or wrist strap protects equipment from ESD voltages on the body only; ESD voltages on
clothing can still cause damage to electronic components.

Removing the Cable Management Brackets
The cable management system for the Cisco 12404 Internet Router has a chassis cable management
bracket and a cable management bracket for each line card.
Before removing the chassis cable management bracket, remove the line card cable management
brackets and network interface cables (NIC) to prevent cable damage.
Step 1
Attach an ESD-preventive strap to yourself and to either the chassis, or to a bare metal surface. (See
Figure 1.)
Step 2
Remove the velcro straps from the line card cable management bracket. See the top illustration in
Figure 2.

Step 3
Carefully disconnect the (NIC) from the line card(s). Remove the NICs from the chassis cable
management bracket and secure them safely.
Step 4
Use a Number 2 Phillips screwdriver to unscrew the two captive screws that attach the cable
management bracket to the router processor (RP) or line card. Repeat this step for each card that has a
cable management bracket attached.
Step 5
Remove the RP and line card management bracket.
Caution
Carefully adjust the interface cable in the RP or line card cable management bracket to prevent any
kinks or sharp bends in the interface cable. Kinks and sharp bends can destroy or degrade the ability
of the optical fiber to propagate the signal-encoded beam of light accurately from one end of the cable
to the other. Also, allow adequate strain relief in the interface cable.
Step 6
Use a Number 2 Phillips screwdriver to remove the two screws that attach the chassis cable
management bracket to the chassis.
Step 7
Carefully remove the chassis cable management bracket. (See Figure 3.)

Attaching the Cable Management Brackets
Step 1
Attach an ESD-preventive strap to yourself and to either the chassis, or to a bare metal surface. (See
Figure 1.)
Step 2
Use a Number 2 Phillips screwdriver to attach the chassis cable management bracket to the left side of
the chassis. (See Figure 3.)
•
Use the 2 screws packaged with the cable management bracket kit.
Step 3
Orient the top of the line card cable-management bracket with the top of the RP or line card faceplate.
See the top illustration in Figure 2.
Step 4
Align the two captive screws on the bracket with the threaded insert holes near the ejector levers on
each side of the RP or line card faceplate.
Step 5
Attach the line card cable management bracket to the line card. (Repeat for each line card as needed.)
•
Caution
Tighten the 2 cable management bracket captive screws to the RP or line card.
Do not overtighten the captive screws; you might strip the threads on the screw or in the insert in the
line card faceplate.
Step 6
Pull the small end of the velcro strap through the slot in the cable management bracket.
Step 7
Insert the small end of the velcro strap into the slot in the wide end of the velcro strap.
Step 8
Pull the small end through the velcro strap slot to secure it to the cable management bracket.
Step 9
Proceeding from left to right on each card, identify the network interface cables (NIC) that attach to the
RP or line card. (See Figure 2.)
Step 10
Carefully route the identified NIC through the previously chassis mounted cable management bracket
and over to the card interface port; do this for one NIC at a time.

Step 11
Caution
Proceeding from left to right identify the NIC that connects to each card port and connect the NIC to
the RP or line card port.
Carefully adjust the interface cable in the RP or line card cable management bracket to prevent any
kinks or sharp bends in the interface cable. Kinks and sharp bends can destroy or degrade the ability
of the optical fiber to propagate the signal-encoded beam of light accurately from one end of the cable
to the other. Also, allow adequate strain relief in the interface cable.
Step 12
Proceeding from right to left carefully wrap the NIC using the velcro straps. See the bottom illustration
in Figure 2.
Step 13
Route the NIC along the cable management bracket.
Note
For easy removal of line cards, ensure that all connected NIC cables do not block others line cards
during the cable management installation.
