Replace Rear Fan Module

You will need to replace a rear fan module if one of the two fans within the module fails. The rear fan modules must be replaced within one minute to prevent the blades from overheating. You can remove and replace a rear fan from a powered-off system or from a powered-on system using a hot-plug procedure.

The rear fan modules are customer-replaceable units (CRUs).

Before You Begin

You will need a Phillips No. 2 screwdriver to replace a rear fan.

Removing and Installing a Rear Fan

  1. Prepare the system for a hot-plug operation.

    See Prepare Components for Hot-Remove Operation.

  2. Using a Phillips No. 2 screwdriver, loosen each of the two captive screws on the front of the fan until the screws turn freely.

    The illustration below shows the rear fan removal from a Sun Blade 8000 Chassis. The rear fans in a Sun Blade 8000 P Chassis are in a similar location.

  3. Holding the two screwheads, pull the fan module out of the fan cage approximately 2 inches (5 cm).

    Pull the rear fan out of the fan cage using the fan screwheads.

  4. Shift one hand below the fan module to support its weight and pull the module completely out of the chassis.

Installation is the reverse of this procedure.

Finishing the Rear Fan Replacement

After you install the rear fan module, the Chassis Monitoring Module (CMM) will automatically detect the new module. To verify that the rear fan module is replaced properly, see Verify Hot-Insert Operation.
