4400 Systems Installation and Troubleshooting Guide
This topic includes instructions on upgrading your system with a
third power supply to provide redundant power capability to the system.
To install an additional power supply, follow these steps:
NOTICE: The power supply is heavy. Support it with both
hands when installing it.
- Remove the power supply-bay close-out panel from the back of the
system chassis.
- To open the handle of the new power supply, press down on the handle
release in the middle of the power supply handle (see Figure 1).

- With the new power supply's handle in the open position, slide the
power supply into the chassis to the point where the power supply initially stops.
NOTICE: Do not use excessive force when sliding the power
supply into the chassis.
- Rotate the power supply handle to the closed position.
The handle acts as a lever to push the power supply into the proper position inside
the chassis.
- With the power supply fully inserted into the chassis, close the
handle completely so that the latch engages.
 |
NOTE: The power supply will not
function until the handle is closed. |
- Connect the power cable to the power supply and route the cable
through the strain-relief clips on the power supply handle.
- Plug the power cord into the power supply.
- Check that the green LED indicator lights up on the newly-installed
drive.
