3 Facing the front of the BIP, ensure all breakers are off (the O is pushed in).
See the figure “Circuit breakers on the front of the BIP” (page 856).
4 Turn on the cooling unit by switching on the third breaker (the middle one)
on the 2 BIMs at the right. Switch on a breaker by pushing the bar symbol
( | ) in.
5 Continuing from the right side of the 2 BIMs on the right, switch on the
breakers one at a time until all breakers are on. For a Passport 15000 or
20000 with BIMs installed in a frame that is waiting for the second (upper)
node, leave the breakers of BIMs in slots 1 and 2 off.
6 On the alarm module, test the operation of the LEDs in the BIP by
pressing the button labelled Test LED that is identified in the figure
“Location of alarm module status LEDs” (page 864). (The BIM breakers
can be on or off.) The six LEDs below the button pass the test when they
stay on for approximately 10 seconds.
7 After all breakers of each BIM are switched on, observe the LEDs cycling
from solid red to solid green. Ensure that the LED status of the alarm
module and the BIMs are green. See the figure “Location of BIM status
LEDs” (page 863). If not, power down all breakers and trouble-shoot the
problem.
8 When the BIP is powered from an MFA150 system of ac rectifiers, check
the AMP readings on the front of each rectifier. The acceptable range of
current is approximately 7 to 50 amps depending on the number and type
of seated processor cards in the Passport 15000 or 20000.
