Hot Swapping Power Supplies
The power system contains four 800-watt autoranging power supplies. The third bay’s power supply
from the left as you face the chassis serves a redundancy function for the server’s power supply
requirements.
CAUTION Because of chassis airflow disruption, the power supply bay should not be vacant
for more than five minutes when server power is on. Exceeding the five-minute
limit might cause system cooling to fall below the minimum required level and
possibly cause damage to system components.
NOTE The server requires a minimum of three power supplies to operate. If you have
only three power supplies operational, they must occupy the first, second, and
fourth power supply bays as you face the chassis. Figure 3-3 shows the power
supply installation order.

If only 3 power supplies
are operational, place a
filler panel over the fourth
bay in the installation order.
