B.5 Fan Unit
The fan units generate an airflow between the inside and outside of the server. If an
error occurs in one fan unit, the XSCF detects the error and the normally operating
fan unit starts rotating at a higher speed to cool the server. The M3000 server uses
the fan units (FAN_A) as its main cooling system.
TABLE B-8 shows the fan unit
specifications.
For the replacement procedure, see Chapter 13.
