Front fan modules are built into the Sun Blade 8000 Chassis only. You can remove and replace a front fan module from a powered-off system or from a powered-on system using a hot-plug procedure. Do not leave a front fan module slot vacant. Keep a failed front fan module installed in the chassis so that the module can block air recirculation.
The front fan module is a customer-replaceable unit (CRU).
Prepare the system for a hot-plug operation.
Using a Phillips No. 2 screwdriver, unscrew each of the two captive screws on the front fan cover until loose.
Remove the front fan cover.
Push down on the front fan module handle and pull the front fan module out of the fan tray while supporting the bottom of the fan module with your other hand. The number 1 in the illustration shows the location of the front fan module handle.
Installation is the reverse of this procedure.
When you install the front fan module, ensure that the module locks into place. The Chassis Monitoring Module (CMM) will automatically detect the fan module replacement. To verify that the front fan is replaced properly, see Verify Hot-Insert Operation.
