Installation
The PS19 AC power supply is inserted into the Coral IPx cage in the extreme left slot.
Before installing the power supply, verify that the ring frequency configuration jumper
is set to the correct frequency (20Hz or 25Hz). See the table on
Frequency
Adjustment.
Installing the Power Supply
1.
Verify on the cage rear panel that the POWER SUPPLY DUPLICATION connector
is not in use.
Connecting the POWER SUPPLY DUPLICATION connector (located on the cage rear
panel) for PS19 AC power supplies will result in damage to the system. This connector
is only used with the PS19 DC-D power supply, see
Supply Duplication Cable between Two
PS19 AC power supply is installed.
2.
Verify that the PS19 AC power switch is turned OFF.
Inserting the PS19 AC 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 PS19 AC card, 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 label on the bottom of the cage slot.
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 unit into the slot. Irreparable damage may occur if the multi-pin
connectors misalign while you attempt to insert the unit. If more than slight
resistance is encountered, partially slide the unit out of the card cage and verify
the alignment of the guide ridges with the unit edge guides. If alignment appears
to be correct, remove the unit from the slot and inspect the multi-pin connectors
for bent pins and debris in the pin holes.
