Installing or Replacing a PRE4
Step 4
Simultaneously pivot both ejector levers (see
) toward each other, until they are parallel to the
faceplate, to firmly seat the PRE4 in the backplane.
The PRE4 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
) to secure the PRE4 to the chassis.
Caution
To ensure that there is adequate space for additional line cards, always tighten the captive
screws on each newly installed PRE4
before
you insert a standby PRE4 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 PRE4” section on page 19
for information about configuring the PRE4.
