Using a flat head screwdriver, re-install the plastic terminal block covers that
were removed in
11
Dress the power cable to the right and use a cable support on the right
chassis bracket to help retain the cable. This helps relieve the cord weight
form the connector and avoid the inadvertent disconnection of the power
supply cord.
12
At the breaker, connect the power input wires for PSA and PSB and tighten
the set screws (if present).
Note:
Separate breakers should be used for PSA and PSB. This ensures
that power can be removed from one power supply so that it can be replaced
while the unit is operating.
13
Restore power to the input DC circuit for PSA and PSB.
The power supplies will turn on.
14
Verify the power supply LEDs. The following LED indications should be
present on the 3930:
•
PSA - Status LED is solid green, Input LED is solid green
•
PSB - Status LED is solid green, Input LED is solid green
•
PWR - solid green
Note:
The system does not distinguish between a faulty and an unpowered
supply. As a result, if redundant power supplies are installed, but only one
supply is connected to a power source, the unpowered supply will cause the
system to report an alarm state (ALRM LED solid yellow and STAT LED off).
This alarm will be cleared when the power supply is properly initialized.
The power supplies have now been installed and the system has been
powered on.
