Replacing the Fan Module
Figure 43 illustrates replacing the Fan module.
Tools required:
• torque driver for Phillips screws
To replace the Fan module:
Step 1. Hold the replacement Fan module by its edges, align it with the slot guides, and slide
it into the slot.
Step 2. Press the Fan module firmly into the slot. Make sure that the Fan module connectors
are seated in the backplane connectors.
Step 3. Secure the Fan module by tightening the captive screw. Do not over-tighten. The
recommended torque is 4-6 lbf-in.
Step 4. Verify that the Batt A and/or Batt B LEDs on the Fan module faceplate are lit. When
lit (green), the system is receiving power from power feeds A and/or B. At least one
of the Batt LEDs must be lit. Refer to Fan Module Connectors and LEDs on page 130
for more information on Fan module LEDs.
