The power supply unit is inserted into the Coral IPx 500 cage in the extreme left
slot.
Installing the Power Supply
1. Verify that the cage ground wire is connected and the ground nut is tightened. (see
Figure 7-8 ).
2. Verify that the power switch is turned OFF.
3. Position the two guide ridges (located on the right panel of the power supply, at
the top and bottom) into the card edge guides corresponding to the POWER
SUPPLY slot labeled on the bottom of the card cage.
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 captive screws on the top
and bottom of the front panel. See Figure 7-5 on page 7-18 .
4 Installation
Inserting the power supply card into the cage when the power switch is ON could result
in a sudden surge voltage that could damage the Coral IPx system. Before inserting the
power supply unit, verify that the power switch is turned OFF.
The screws on the front panel must be tightened properly to prevent dangerous
electrical shock.
