3. Orient the new fan so that the light on the top of the fan is to the right side of the
server.
4. Push the replacement fan assembly into the server until it clicks into place.

Replacing fans 3 and 4
As shown in the illustration, these two fans (fan 3 and fan 4) are located in front of the
I/O board and the PCI-X slots. They are used to cool the hard disk drives, I/O board,
and PCI-X slots.These fans are redundant, meaning that if one fails, the remaining fan
will temporarily speed up to properly cool the I/O components in the server. In the
event of a failure, you must replace the malfunctioning fan within 48 hours.
Complete the following steps to replace fans 3 and 4:
1. Review the information in “Working inside a server with power on” on page 9 and
“Before you begin” on page 9.
Attention: All fans must be replaced within 48 hours of failing.
