Removing and Replacing the PRE Module

Replacing the PRE Module

When replacing a PRE1 module with a PRE2 module, you must also install EMI gaskets and RF absorber material, for more information, go to the following URL:

Step 1 Grasp the faceplate of the new PRE module 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 2 Carefully align the upper and lower edges of the PRE module with the upper and lower guides in the chassis, and slide the module into the slot until you can feel it begin to seat in the backplane connectors (see Figure 5-28).

Step 3 Simultaneously pivot both ejector levers toward each other (until they are parallel to the faceplate) to firmly seat the PRE module in the backplane (see Figure 5-29).

Step 4 Secure the PRE module in the chassis by tightening the top and bottom captive screws (see Figure 5-25).

Caution Always tighten the captive screws on each newly installed PRE module. These screws prevent accidental removal and provide proper grounding for electromagnetic interference (EMI) shielding.
