Removing a DC Power Supply
1.
Turn off the DC power source or disconnect it from the power supply.
2.
Loosen the three screws used to hold the wires in the connector, then pull out the wires.
3.
If necessary, remove the power supply locking screw located in the center rear of the device.
4.
Press the two latches near the edges of the supply inward to unlock the supply.
5.
Hold the bar on the front panel of the power supply and pull outward. This will disconnect the power supply
from the backplane.
6.
Continue to pull the power supply until it is removed from the device.
7.
Place the power supply in an anti-static bag for storage.
8.
Insert a new supply, or place the cover plate over the empty power supply bay and press the two latches near
the edges of the supply outward to lock the plate into place.
9.
If necessary, replace the power supply locking screw.
Installing a DC Power Supply
1.
If necessary, before installing a power supply, 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 edges of the cover
plate to unlock the plate, then remove the plate.
3.
Remove the power supply from its packaging.
4.
Prepare the positive, negative, and ground wires by stripping about 1/4" of insulation off the end of each one.
(Use 14 AWG wire.)
5.
Loosen the three screws used to hold the wires in the connector. These are the wires under the following
markings:
6.
Slip the ground wire into the opening under the
marking until the wire is fully in place, then tighten the
screw to hold the wire in place.
7.
Repeat for the negative (—) and positive (
+
) wires.
8.
Pull gently on each wire to make sure they are securely fastened in the connector.
9.
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 are fully engaged 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.
