Prepare the Server for Cold Service
■
On a four CMOD system, when both fans in a single column are removed from the left-
hand fan frame (CMODs 0 through 3), or when a CMOD is inserted into an unoccupied
CMOD slot (4 through 7).
Caution -
Data Loss. Do not remove more than one fan module from a column while the system
is in full power mode. This action removes power from the CMODs and causes an immediate
shutdown. On an eight-CMOD system, this applies to all fan modules. On a four-CMOD
system, this applies to the fan modules in the left-hand fan frame (CMODs 0-3).

Prepare the Server for Cold Service
Note -
This procedure uses a combination of the Oracle ILOM web and CLI interfaces.
However, the procedure can be performed using only the Oracle ILOM CLI interface (for more
information, refer to the Oracle ILOM documentation).
A
cold-service
component must be serviced when the server is completely powered off.
For more information about component serviceability, see
.
This procedure describes how to prepare the server for service, so you can:
■
Remove, replace, or install cold-serviceable components.
■
Use the motherboard processor and DIMM fault remind circuitry.
■
Access internal components, such as the internal USB drives.
Before You Begin

Important
: Review the
for hardware-related information
before performing removal and installation procedures.
