Determining the status of a CID card

4

For absent or faulty indications, contact the Brocade VDX 8770-4 supplier to order replacement
parts. You may also want to do this if the indication is below minimum or above maximum.

Table 16

describes the LED patterns for the fan.

Determining the status of a CID card

Each CID card has two serial EEPROMS (seeproms). One is the critical seeprom and the other is the
non-critical seeprom. Problems with the critical seeprom cannot be fixed with the CID Recovery
Tool. Only issues with the non-critical seeprom can be addressed.

Regular validation tests are run by the system comparing the CID cards to each other. If the
information is identical, then the chassis is operating correctly. Once a mismatch is detected, an
FFDC message is output to the RASlog. Refer to

Table 17

for possible messages.

unknown

Unknown fan unit installed.

faulty

Fan has exceeded hardware tolerance
and has stopped. In this case, the last
known fan speed is displayed. Could also
mean that the fan is improperly seated.
