Installing or Replacing a 3-kW Universal AC/DC Power Supply
1
Turn off the power supply (and circuit breaker for a
DC circuit).
2
Verify that the OK LED turns off.
3
Press and hold the release button on the plug.
4
Pull the power cable plug out of the power supply
receptacle.
b) Slide the middle of the ejector lever down to the end of the lever and rotate the lever away from the chassis.
The power supply unlocks from the chassis and moves out slightly.
c) Pull on the lever to move the power supply about 2 inches (5 cm) out of the slot.
d) Place one hand on the front of the power supply and your other hand under the power supply to support its weight.
e) Pull the module out of the slot and place it on an antistatic surface or inside an antistatic bag.
Step 4
To install the new power supply, follow these steps:
a)
If you are using a DC power source, ensure that the circuit is turned off at the circuit breaker.
b)
Hold the front of the power supply module with one hand and place your other hand under the module to support
its weight.
c)
Rotate the power supply 90 degrees so that the power receptacle is positioned on the lower front side. And so that
the back of the power supply is oriented to slide into the open power supply slot.
d)
Slide the guide bracket that is located on the top of the power supply into the track at the top of the power supply
slot. Slide the power supply into the slot until the front of the module stops about 0.25 inches (0.6 cm) in front of
the module.
e)
Slide the handle on the middle of the power supply release lever toward the end of the module and rotate the lever
away from the front of the power supply while pushing the power supply all the way into the chassis. See the
following figure.
