Chapter 5 Maintaining the Router

Removing and Replacing an RP or Line Card

Step 9 Tighten the captive screws on the card.

Note The card captive screws must be tightened to meet EMI specification standards.

Repeat Step 1 through Step 9 for any additional replacement RPs or line cards, and then proceed to the next section.

Attaching the Cable-Management Bracket and Connecting Cables

The Cisco XR 12404 router line cards use cable-management brackets to:

Organizing the network interface cables

Keeping the network interface cables out of the way

Positioning connectors at their respective ports on the line card faceplate

Keeping the cables free of sharp bends (excessive bending in a network interface cable can cause performance degradation)

When you install a new RP or line card, you need to attach the line card cable-management bracket to the faceplate of the card before connecting the cables. The type of cable-management bracket used by a line card is determined by the card type and the number of network interface ports it has.

Use the following procedure to attach the cable-management bracket and cables to a line card.

Step 1 Orient the top of the cable-management bracket with the top of the line card faceplate (the end opposite the two four-character alphanumeric displays.)

Step 2 Align the two captive screws on the bracket with the threaded insert holes near the ejector levers on each end of the line card faceplate and finger-tighten the screws.
