Oracle X7-2 Service Manual

Servicing Fan Modules (CRU)
This section describes how to service fan modules. Fan modules are customer-replaceable units
(CRUs) that do not require you to power off the server. For more information about CRUs, see
“Illustrated Parts Breakdown” on page 19 and “Customer-Replaceable Units” on page 21.
The fan modules are located in the front of the server. See the following procedures:
■
“Remove a Fan Module” on page 81
■
“Install a Fan Module” on page 84

Remove a Fan Module
You do not have to power off the server to service the fan modules.
You should not begin this procedure unless you have a replacement fan and you are ready to
install it right away.
Caution - When removing and replacing a fan module in the Oracle Server X7-2, you must
complete the entire procedure within 20 seconds to maintain adequate cooling within the
system. Remove and replace only one fan module at a time. Ensure that you have obtained the
replacement fan module and that is it is ready for installation before starting the replacement
procedure. Each fan module contains two fans, with two fan motors per fan. The four fan
motors provide separate tachometer signals so that the fan module reports four tach signals to
Oracle ILOM. Even if only one fan motor is faulted within the fan module, the Oracle ILOM
service processor detects that four fan motors have failed to spin while the fan module is
removed. If the fan module is not replaced within 20 seconds of removal, Oracle ILOM will
take the protective action to shut down the system to prevent thermal damage to the system.
