Maintenance Analysis Procedures (MAPS)

Is fault isolation being performed at the director?

YES NO

↓ Fault isolation is being performed at the management server

or customer-supplied server, or SANpilot interface. Go to

step 10.

Inspect both fan modules at the rear of the director. Fan module LEDs

can be inspected through the hexagonal cooling vents of the radio

frequency interference (RFI) shield.

Does inspection of a director fan module indicate a failure? Indicators

include:

• The amber LED is illuminated but not blinking (beaconing) on

one or both fan modules.

• One or more cooling fans are not rotating.

YES NO

↓ Go to step 6.

One or more cooling fans failed, and one or both fan modules must be

removed and replaced (RRP: Fan Module on page 5-30).

• If a multiple fan failure caused a thermal shutdown, power on the

director after the fan modules are replaced (Power-On

Procedure on page 4-52).

811 Critically hot temperature warning (CTP2 card

thermal sensor).

Go to step 7.

812 CTP2 card shutdown due to thermal violation. Go to step 7.

850 System shutdown due to CTP2 card thermal

violations.

Go to step 7.
