Hot-Swap Chassis Fan Units

Hot-Swap Chassis Fan Units
There are five hot-swap chassis fan units in the HP Server. Fan units 1, 2, 3 and 4 are accessible from the
front of the chassis. Fan unit 5 is accessible from the rear of the chassis. Fan units 1, 2, 3 and 4 are identical
and interchangeable.
If a fan failure is total (both rotors), or if the fan has been removed from the chassis for more than 30 seconds,
a system will log the event as a critical error. A critical error will cause the System LED to flash red and will
require a reboot to reset the error status. A total fan failure (including removal) for more than 2 minutes will
result in system shutdown. If you are hot-swapping a fan assembly in response to an error message, and the
system is operating normally, hot-swapping the fan in less than 30 seconds will eliminate the requirement for
a system reboot. Hot-swapping a fan in less than 2 minutes will allow continued operation and prevent
automatic shutdown.
CAUTION Operating the server with the front grill removed will risk EMI. Operate the server with the
front grill removed only when hot-swapping a fan. Always replace the front grill immediately
after replacing the fan.
Observe all ESD safety precautions while performing this procedure. Failure to follow ESD
safety precautions could result in damage to the server.
NOTE A hot-swap device does not require interaction with the operating system before the device is
removed from or installed into the server.
The power to the server does not have to be off to remove or replace a hot-swap chassis fan unit.
