Procedure
To install a line card:
1. If you are installing the line card into Slot 18, remove the single filler plate and
store it in a safe place. If you are installing a line card into a slot other than Slot
8 or 18, see
Installing Line Cards into Slots 1–7 and 10–17 on page 2-20
before continuing with this procedure.
2. Hold the line card vertically and insert it into the top and bottom card guides of
the desired slot. For example, insert the card into Slot 8 as illustrated below.
3. Slide the line card into the slot. Gently but firmly push the card until it properly
seats in its mating connectors on the backplane.
CAUTION:
Do not force the line card into the slot. If it does not seat properly,
remove the card and reinstall it. If it still does not seat properly, call
service.
4. The line card will now perform a power-on self-test. All of the LEDs turn ON
and OFF briefly. When the self-test is completed successfully, the SYSTEM
OK LED will turn ON. Make sure the
SYSTEM OK indicator on the line card
faceplate is blinking green.
For a more detailed explanation of LEDs on the line card, refer to the
appropriate line card documentation.
5. Secure the line card by tightening the top and bottom screws on the faceplate
while applying slight pressure to the left to insure a good seal. This is required
to maintain proper gasket pressure on the faceplate.
NOTE:
If a new line card is not installed in this slot, a gasketed, single filler plate must
be installed to provide shielding and proper air flow.
