To Replace a Fan Module (CRU)
Each fan module (also known as a fan tray) has two fans. The server has five fan
modules (10 fans per server). This component is customer replaceable.
Note –
Enclosure cooling might be affected by dust and contaminant build-up. It is
recommended that the enclosure be opened and checked approximately every six
months, or more often in dirty operating environments. Check component heat sinks,
fans, and air openings. If necessary, clean the enclosure by brushing or blowing
contaminants or carefully vacuuming contaminants from the enclosure.
Note – This component can be replaced by anyone.
TABLE 3-8
lists the qualified part numbers for this component. This part number is

Caution –
The fans are hot-swappable and can be removed and replaced while the
system is running. Do not keep the fan tray access cover open for more than 60
seconds at a time to avoid overheating the server. Remove and replace only one fan
module at a time.
Fans are labeled FT0 (fan tray 0) to FT4 (fan tray 4). See “Locations of Components”
on page 3-2 .
1. If the server is in a rack, slide it far enough out of the rack so that you can
access the fan modules.
