Installing an AC Power Supply
To install an AC power supply, do the following:
1. If necessary, remove the power supply locking screw located in the center rear of the device (illustrated
below).
2. If the empty power supply bay has a cover plate, press inward on the two latches near the left and right edges
of the cover plate to unlock the plate (illustrated above), then remove the plate.
3. Remove the new power supply from its packaging.
4. With one hand, hold the bar on the front panel of the power supply. With the other hand, support the
underside of the power supply, and insert the power supply into the empty power supply slot. Press until the
supply is completely in the slot, so that the connectors on the back of the supply fully engage with the pins on
the power backplane.
CAUTION: Make sure you insert the power supply right-side up. It is possible to insert the supply upside down,
although the supply will not engage with the power backplane when upside down. The power supply is right-side
up when the power connector is on the left and the fan vent is on the right.
The following illustrations show how to install an AC power supply.
