4For each
•The main circuit breaker in the pedestal did not trip OFF.
•The main blower unit in each column is running.
•The ringing generators are lit.
•The red column LEDs in the top cap are lit. These LEDs will remain red until the system reloads.
5Simultaneously turn the main circuit breakers for the two Core columns ON.
6For each Core column, verify the following:
•The main circuit breaker in the pedestal did not trip OFF.
•The main blower unit in each column is running.
•The ringing generators are lit.
•The red column LEDs in the top cap are lit. These LEDs will remain red until the system reloads.
7When the system is running, reattach all covers and panels to the modules and columns. Module covers must be kept on so the air from the pedestal fans will be directed up through all the modules and out the exhaust vents in the top cap. When the module covers are removed, the upper modules are not cooled properly because the air escapes from the open module door.
If the module covers are left off and the system overheats, circuit cards will malfunction and, in extreme cases, melt.
