10 Replace the distribution fuses, or set the distribution breakers to ON, on
the DC power source for the column.
11 Set the circuit breaker for the blower unit (the far left breaker in the rear
of the pedestal) to ON in the column.
12 Set the switch on the blower unit (in the front of the pedestal) in the
column to ON. You should hear the blower running.
Note: On initial power-up, the blower may rotate slower than expected.
As the sensor detects heat, the blower will rotate faster.
13 Set the switch on the module power supply to ON in the column. After a
few seconds, the green LED on the power supply should light.
Repeat this step for each module in the column, one at a time. (If the
module is equipped with a ringing generator, set the switch on both the
power supply and the ringing generator to ON).
Note: It may take up to 90 seconds for the green LED to light on a
ringing generator. This is normal operation.
At power-up, a sysload starts and completes. At this point the terminal
connected to the CPIO port becomes active. Watch for system reload (SYS)
and initialization (INI) messages.
When the sysload is complete, the system automatically invokes the
initialization program. The red column LEDs should go off. When the
initialization is complete, the system automatically runs the programs in the
midnight routine.
Note: The red LED on NT8D04 and QPC414 Network cards remains lit
until the network loops are configured and enabled.
