Installing a PRE3
Use the following procedure to install the PRE3 into slot 0A or slot 0B in the Cisco 10008 chassis.
Step 1 Attach an antistatic strap to your wrist or ankle and to an ESD socket (see Figure 5 ) on the chassis, or to
a bare metal surface on the chassis or frame.
Step 2 Grasp the faceplate (see Figure 6 ) of the PRE3 with one hand and place your other hand under the frame
of the PRE3 to support the weight of the PRE3. Position the PRE3 in front of the chassis slot.
Step 3 Carefully align the upper and lower edges (see Figure 6 ) of the PRE3 with the upper and lower guides
in the chassis, and slide the PRE3 into the slot until you can feel it begin to seat in the backplane
connectors.
Step 4 Simultaneously pivot both ejector levers (see Figure 7 ) toward each other, until they are parallel to the
faceplate, to firmly seat the PRE3 in the backplane.
The PRE3 cycles through its power-on self-test. The FAIL LED stays on briefly (10 to 15 seconds) and
then shuts off.
Step 5 Tighten the top and bottom captive screws (see Figure 8 ) to secure the PRE3 to the chassis.
Caution To ensure that there is adequate space for additional line cards, always tighten the captive
screws on each newly installed PRE3 before you insert a standby PRE3 or any additional line
cards. The captive screws prevent accidental removal and provide proper grounding for EMI
shielding.
Step 6 Refer to the “Configuring a PRE3” section on page 14 for information about configuring the PRE3.
