For each non-Core column, verify that:
•
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.

When 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
