Removal and Replacement Procedures 29
CAUTION: To prevent improper cooling and thermal damage,
do not operate the server unless all bays are populated with either a
component or a blank.
2. Remove the power supply blank.
WARNING: To reduce the risk of personal injury from hot
surfaces, allow the power supply or power supply blank to cool
before touching it.
To replace a power supply blank:
1. Slide the power supply blank into the bay until it locks into place.
2. Swing the cable management arm into place and lock it.
Hot-Plug Fan
The server supports redundant hot-plug fans to provide proper airflow to the
system if a primary fan fails. The server airflow is divided into three zones:
processor, I/O, and power supply. Shared fans 4 and 7 each provide airflow for
two zones. If a shared fan fails, the failure is experienced in both zones.
In the standard configuration, five fans cool the server: fans 2, 4, 5, 6, and 7 in
the processor zone; fan 4 in the I/O zone; and fan 7 in the power supply zone.
