Remove A Fan Module - Oracle Sun Server X4-4 Service Manual

Remove a Fan Module

Fan modules provide server cooling to the motherboard and its components. The fan modules
are arranged in stacked pairs (a front row and a back row) to provide redundancy. If you remove
a fan module fails, replace it immediately.
Fan modules are hot-serviceable components. It is not necessary to power off the server
or to remove the server cover to service a fan module. However, depending on server rack
configuration, it might be necessary to partially extend the server from the rack to access the
fan modules. (Optional steps for partially extending the server from the rack are included in
this procedure.) Take care when partially extending the server from the rack during hot service.
Ensure that the cables at the back of the server do not become dislodged, particularly the power
cables. As an option, you can also perform this procedure using cold service.

2. If necessary, slide the server partially out from the rack.
a. At the back of the server, verify that the cables have sufficient length and
clearance to extend the server.
The cable management arm (CMA) that is supplied with the server is hinged to facilitate
extending the server to the maintenance position. However, ensure that the cables do not
impede with, or are damaged by, the sliding movement. If necessary, label and remove
cables from the back of the server.
b. (Optional) To move the CMA for access to the back of the server, see
