Cooling Subsystem; Power Subsystem - HP Integrity rx2800 - i2 User's & Service Manual

Cooling subsystem

Six fans cool the server. The fans are all redundant, hot swap capable, and interchangeable. If
one fan unit fails, the others increase speed to compensate for the failure. The fan units are N+1,
meaning that the server has six fan units, but can operate with five fan units running.
Figure 4 Fan identification
The power supplies have built-in fans and are not controlled by the BMC.

Power subsystem

The server supports 1+1 redundant power supply for high line (1200W/200~240VAC) and low
line (800W/100~120VAC) in the data center and office friendly server versions. Power redundancy
is identified the following table.
