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.

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.

Figure 2 RP and Line Card Cable Management Brackets

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.)

Figure 3 Chassis Cable Management Bracket


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.)

Tighten the 2 cable management bracket captive screws to the RP or line card.


Caution 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 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.


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 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.
