Installing an MCP Card
Use a flat-blade or Phillips screwdriver to install an MCP card into Slot 9.
Procedure
To install an MCP card:
1. Remove the single filler plate from Slot 9 and store it for future use.
2. Position the MCP card vertically and insert it into the top and bottom card
guides of Slot 9.
3. Slide the MCP 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 MCP card into the slot. If it does not seat properly,
remove the card and reinstall it. If it still does not seat properly, call for
service.
4. The MCP 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 OK
SYSTEM indicator on the MCP
faceplate is ON (blinking green).
5. Secure the MCP card by tightening the top and bottom screws on the
faceplate. This is required to ensure proper pressure on the EMI gaskets and
to maintain proper air flow.
