Replacing a Hot-Swappable Chassis Fan Unit
CAUTION:
To prevent server components from overheating, replace the fan within 20 seconds. Failure to
observe this caution results in the server automatically shutting down to prevent an overtemperature
condition.
NOTE: The fan unit is keyed to fit into the fan housing in the correct orientation only.
To replace a hot-swappable chassis fan unit, follow these steps:
1. Push the fan unit firmly into the fan housing until it is flush with the top of the chassis.
NOTE: It can take up to ten seconds after installation for the new fan LED to turn off.
2. Check the diagnostic LED that corresponds to the replaced fan unit.
• When the fan is functioning normally, the LED is off.
• If the fan fails, the LED is lit.
3. Replace the server top cover. See “Replacing the Top Cover” (page 166).
