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 20
“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 85

“Install a Fan Module” on page 87

Remove a Fan Module
You do not have to power off the server to service fan modules.
You should not begin this procedure unless you have a replacement fan module and you are
ready to install it right away.
Caution -
When removing and replacing a fan module in the Oracle Server X7-2L, 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 one fan motor per fan. The two fan motors
provide separate tachometer signals so that the fan module reports two tach signals to Oracle
ILOM. Even if only one fan motor is faulted within the fan module, the Oracle ILOM service
processor detects that two 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.
