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.
