HP 9000 rp5400 Servers - Manual (Page 119)

To replace a fan, perform the following steps:
1. Orient the fan assembly to ensure that the chassis outlet connects with the fan assembly. If
the fan power connector is covered by the protective cover (see item 1 in the graphic), slide
it down to remove it and slide it over the power connection on the other side of the fan.
Push the fan firmly into the housing. The fan assembly will plug into the electrical outlet
automatically.
2. Check the LED located on the fan.
•
When the fan is functioning normally, the LED is OFF.
• When the fan fails, the LED is ON.
NOTE: when one fan has failed (or is removed from the server), the system automatically
puts the remaining fan into high speed mode. The noise level of the server will increase.
3. Replace the HotSwap Chassis fan cover.

HotSwap Card Cage Fan Removal
The power to the server does not have to be off to remove or replace a HotSwap Card Cage fan.
Fans numbered 2, 3, 4, and 5 are located in a four-fan assembly housing located on the left side
of the server's side service bay.
CAUTION: Running the server for extended periods of time with a cooling fan removed may
create hot spots inside the server and shorten component life.
If other fans fail when one fan is removed, the system will halt.
To remove a fan from the server, perform the following step:
Identify the fan to be removed and pull it out of the Side Fan Assembly Housing. It will
automatically disconnect from its electrical outlet on the I/O Backplane.
NOTE: When one fan has failed (or is removed from the server) during operation, the system
automatically puts the remaining fans into high speed mode. The noise level of the server will
increase.
