Power Supplies
Your appliance supports two redundant 750 W power supply modules.
n
The power supply label specifies the maximum power output.
When two power supplies are installed, the second power supply provides
hot-swappable, power redundancy. In redundant mode, the appliance distributes
the power load across both power supplies to maximize efficiency. When a power
supply is removed with the appliance powered on, the full power load is picked up
by the remaining power supply.
c
If only one power supply is installed, it must be installed in the PS1 power supply
bay.
Removing a Power Supply
c
If troubleshooting a power supply mismatch error, replace
only
the power supply
with the flashing indicator. Swapping the opposite power supply to make a matched
pair can result in an error condition and unexpected appliance shutdown. To
change from a High Output configuration to an Energy Smart configuration or vice
versa, you must power off the appliance.
To remove a power supply:
1.
Disconnect the power cable from the power source and the power supply you
intend to remove and remove the cables from the Velcro strap.
2.
Press the lever release latch and slide the power supply out of the chassis
(
).
