shutdown in 40 seconds, and the failed fan unit must be replaced. See
Figure 6-8 (page 151)
for
the Office Friendly fan locations and cooling zones.
The power supplies have built-in fans and are not controlled by the BMC.

shows a block diagram of the power subsystem for the rx2660 server, including voltage
labels for each main server subsystem that requires power.

Data Center Server Power
The Data Center server power sub system is designed to provide high availability with 1+1
redundancy. Two hot-swappable ac/dc power supplies generate 12 VDC for the system and
peripherals, and a housekeeping voltage (+3.3 V standby). One active power supply operating
at 100 VAC is sufficient to operate the system at its maximum load. Each power supply receives
ac power through integrated ac inlets. The system can operate at 100, or 240 VAC and achieve
1+1 redundancy. The power supplies are power factor corrected and the maximum dc power
output of each power supply is 900 watts at 120 VAC, and 1000 watts at 240 VAC.
Office Friendly Server Power
The Office Friendly server has two power supplies in the standard configuration. The server is
designed to provide high availability with 1+1 redundancy. However, the server runs more
quietly and efficiently with two power supplies installed. The ac/dc power supplies generate 12
VDC for the server and peripherals, and a housekeeping voltage (+3.3 V standby). Each power
supply receives ac power through integrated ac inlets. The system can operate at 100 or 240 VAC.
The power supplies are power-factor corrected, and the maximum dc power output of each
power supply is 900 watts at 120 VAC, and 1000 watts at 240 VAC.
