8Make sure the green lights in all the module power supplies are lit before proceeding to the next column. The red LED for each column remains lit until the system reloads.
Once 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.
