6. Gently insert the PS19 DC-D power supply completely into its card slot. Push
against the ejectors until the front panel of the power supply is flush with the
front frame of the card cage. A slight resistance can be felt as the multi-pin
connectors on the power supply meet the mating connectors on the backplane and
engage. Do not force the power supply into the slot. If more than slight resistance
is encountered, remove the power supply and examine the connectors for bent
pins or interfering debris.
7. Fasten the two screws located at the top and bottom of the unit front panel, thus
securing the card to the cage as well as grounding the unit.
8. Turn the PS19 DC-D power switch ON, and verify that the green Power indicator
is lit, while the red Alarm indicator is not lit. If the red alarm indicator
illuminates, see
page 7-33, Troubleshooting (PS19 DC-D)
.
9. Turn OFF (downwards) the power switch on the front panel of the PS19 DC-D.
10. Repeat
step 1
through

for each Coral cage in the system.

Tip:
In addition, the PS19 DC-D unit needs to be checked to see that it can
supply another cage. See
page 3-19, Shared Service and Peripheral Card Test
for further details.
Do not proceed until the screws of the power supply card have been fastened to the
cage. If the screws are not fastened, the power supply unit will not be grounded, and
could be subject to hazardous voltages.
