The power supply unit is inserted into the Coral IPx Office unit in the right side of the
IPx Office unit from the rear.
Installing the AC Power Supply
1. Verify that the IPx Office unit ground wire is connected and the ground nut is
tightened. See
Figure 2-10 .
2. Verify that the power switch is turned OFF.
3. Position the two guide ridges (located on the lower panel of the power supply,
at the right and left) into the card edge guides. The power supply slot is
positioned adjacent to the fans in the rear section of the IPx Office unit.
4. Slide the power supply gently but firmly, until fully inserted into the card cage.
A slight resistance should be felt as the multi-pin connectors engage at the rear
of the power supply and backplane.
Do not force the power supply into the card cage. Irreparable damage may
occur if the multi-pin connectors misalign while attempting to insert the unit
into the card cage. If more than slight resistance is encountered, partially slide
out the card from the cage and verify the alignment of the guide ridges with
the card edge guides. If alignment appears to be correct, remove the card from
the slot and inspect the multi-pin connectors for bent pins and debris in the pin
holes.
5.
Secure the power supply unit to the cage with the two removable screws on the
left and right sides of the front panel. See
Figure 7-1
on page 7-2

3 Installation and Activation
Contact with live wires in the power supply unit could cause shock, burn, or death. Do
not connect the power cord or turn ON the power switch of the power supply before
inserting it into the IPx Office system and fastening the screws.
The screws on the front panel must be tightened properly to prevent dangerous
electrical shock.
