4. Slide the unit into the slot until the power and network connectors seat firmly in the
mating connectors on the backplane.
CAUTION:
Do not force the unit into the slot. This could damage the backplane
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.
The unit performs 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 begins to
pulse.
5. If the LED is not pulsing, refer to Monitoring and Troubleshooting in the User’s
Guide.
6. Secure the unit by fastening the screws at each end of the faceplate.
