The PS19 DC-D is installed in the extreme left slot of the peripheral card cage.
The system may be configured for power redundancy with two PS19 DC-D units (one
in each cage) supporting two adjacent cages.
The Hot Standby system is designed to allow hot insertion and hot swaps of a
PS19 DC-D unit, such that, if one of the PS19 DC-D units malfunctions, system
operation is not interrupted because the second unit alone can continue powering
either cage.
Installing the PS19 DC-D
1. Verify that the PS19 DC-D power switch is turned OFF.
2. Position the two guide ridges (located on the right panel of the power supply, at
top and bottom) into the card edge guides corresponding to the POWER SUPPLY
label on the bottom of the cage slot.
3. Slide the PS19 DC-D 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 mis-align while attempting 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.
4. Secure the power supply to the card cage by fastening the two captive screws,
located at the top and bottom of the unit to the cage.
5. Turn the power switch ON, and verify that the green Power indicator is lit while
the red Alarm indicator is not lit.
4 Installation
Do not insert or remove the power supply unit from the cage when turned ON. Sudden
power surges could damage system components.
