Procedure 55
Turning dc power ON
1 Connect each dc rectifier to its associated ac outlet and set the breakers
in the ac power panel to ON.
2 Turn the rectifiers ON one at a time. Wait 10 seconds between each
rectifier.
Note: Power up the Core columns last.
3 On the dc power source for each column, replace the distribution fuses or
set the distribution breakers to ON. Do the Core columns last.
4 Set the blower unit breaker switch ON (the far left breaker in the rear of
the pedestal).
5 Set the blower unit switch in the front of the pedestal to ON. Verify that the
fan is running. On initial power-up, the blower rotates slowly. As the
system heats up, the cooling fans turn faster.
6 Set the power supply switch in each module to ON. The green light will
turn on after a few seconds.
Note: If the module is equipped with a ringing generator, set the breakers
or switches for both the power supply and the ringing generator to ON.
The green LED on a ringing generator normally takes up to 90 seconds to
light.
