Figure 3-16 Removing and Replacing the PRE
Step 8
Grasp the faceplate of the new PRE with one hand and place your other hand
under the card carrier (to support the weight of the module) and position the card
in front of the card cage slot.
Step 9
Carefully align the left and right edges of the PRE with the left and right guides
in the chassis, and slide the module into the slot until you can feel it begin to seat
in the midplane connectors.
Step 10
Simultaneously pivot both ejector levers toward each other (until they are parallel
to the faceplate) to firmly seat the PRE in the midplane.
The PRE cycles through its power-on self-test. The Fail LED stays on briefly
(about 5 to 6 seconds) and then shuts off. If the Fail LED remains on or flashes,
refer to the
Cisco 10000 Series ESR Troubleshooting Guide
.
Step 11
Secure the PRE in the chassis by tightening the left and right captive screws.
Caution
Always tighten the captive screws on each newly installed PRE. These screws
prevent accidental removal and provide proper grounding for electromagnetic
interference (EMI) shielding.
