Power Supplies, Removing a Redundant Power Supply

Page 92 highlights

Power Supplies Your system supports the following power supply modules: • 480W (non-redundant power supply) • 500W (redundant power supply) If two power supplies are installed, the second power supply provides hotswappable, power redundancy. In redundant mode, the system distributes the power load across both power supplies to maximize efficiency. When a power supply is removed with the system powered on, the full power load is picked up 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. 1 Disconnect the power cable from the power source. 2 Disconnect the power cable from the power supply and remove the Velcro straps that bundle and secure the system cables. NOTE: You may have to unlatch and lift the optional cable management arm if it interferes with power-supply removal. For information about the cable management arm, see the system's rack documentation. 3 Pull the power supply straight out to release it from the power distribution board and clear the chassis. 92 Installing System Components

Installing System Components
Power Supplies
Your system supports the following power supply modules:
480W (non-redundant power supply)
500W (redundant power supply)
If two power supplies are installed, the second power supply provides hot-
swappable, power redundancy. In redundant mode, the system distributes the
power load across both power supplies to maximize efficiency. When a power
supply is removed with the system powered on, the full power load is picked
up 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.
1
Disconnect the power cable from the power source.
2
Disconnect the power cable from the power supply and remove the Velcro
straps that bundle and secure the system cables.
NOTE:
You may have to unlatch and lift the optional cable management arm if
it interferes with power-supply removal. For information about the cable
management arm, see the system’s rack documentation.
3
Pull the power supply straight out to release it from the power distribution
board and clear the chassis.
