connectors. If the card does not seat properly, remove the card and reinstall
it. If it still does not seat properly, call your service representative.

mating connectors on the backplane.

When the self-test is completed successfully, the SYSTEM OK LED begins to
pulse.
If the LED is not pulsing, notify your service representative. See Front Panel LEDs
on page 12.
