Installing or Replacing a PRE3
Step 2 Loosen the top and bottom captive screws (see Figure 8 ) on the PRE3.
Note The top and bottom captive screws must be loosened prior to pivoting the ejector levers in Step 3 .
Step 3 Simultaneously pivot both ejector levers (see Figure 7 ) away from each other to disengage the PRE3
from the backplane.
Step 4 Slide the PRE3 out of the slot (see Figure 6 ) and place it on an antistatic surface, or in an antistatic bag.
Step 5 See the “Installing or Replacing a PRE3” section on page 11 for instructions on how to install a new
PRE3.
Note If you are not installing a replacement PRE3, install a blank faceplate in the slot.
Warning Do not operate the system unless all slots contain a PRE3, line card, or a blank faceplate. Blank
faceplates are necessary in empty slots to prevent exposure to hazardous voltages, to reduce
electromagnetic interference (EMI) that may disrupt other equipment, and to direct the flow of cooling
air through the chassis.
Step 6 Power on the system if you have powered it off.
Troubleshooting the Installation
Refer to Figure 2 and Table 1 for descriptions of the LEDs on the PRE3. Follow the instructions in
Table 4 to troubleshoot the installation.
