Power Supplies
Depending on your configuration, your system supports up to two hot-
swappable redundant 580-W power supplies or a single non-redundant 525-W
power supply.
In redundant mode, the system distributes the power load across both power
supplies to maximize efficiency. The second power supply provides power
redundancy; thus, when a power supply is removed with the system powered
on, the full power load is carried by the remaining power supply.
Removing a Redundant Power Supply
CAUTION:
The system requires one power supply to operate the system normally.
On power-redundant systems, remove and replace only one power supply at a time
in a system that is powered on.
CAUTION:
If you are replacing a redundant power supply while your system is on,
ensure that both the power supply status and the AC line status LEDs are green
before removing the power supply (see Figure 1-6). If one or both of the LEDs are
not green, see "Troubleshooting Power Supplies" on page 161.
1 Disconnect the power cable from the electrical outlet.
2 Disconnect the power cable from the power supply and remove the cable
from the cable retention bracket.
3 Press the release latch and slide the power supply out of the chassis.
See Figure 3-16.
4 If you are installing another power supply in the bay, see "Installing a
Redundant Power Supply" on page 122.
If the power supply is being permanently removed, install a power supply
blank. See "Installing a Power Supply Blank" on page 123.
