Installing an SCP Card
SCP cards can be installed in Slot A, Slot B, or both Slot A and Slot B.
Procedure
To install the SCP Card in Slot A or Slot B:
1. If there is a filler plate covering the slot, remove it.
2. Remove the yellow screw covers.
3. Insert the card into the card guides of the slot on the chassis.
4. Carefully slide the card into the slot until the card meets the connectors on the
backplane. Then press in on the insertion/ejection levers until the card is fully
seated.
5. Verify that the SYSTEM Active or Standby indicator on the card’s faceplate is
cycling off and on. See Verifying the Installation on page 2-27.
6. Secure the card by fastening the screws on each end of the faceplate. This is
required to maintain proper gasket pressure on the faceplate as well as proper
air flow.
