Warning
Blank faceplates (filler panels) serve three important functions: they prevent exposure to hazardous
voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might
disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the
system unless all cards, power modules, and faceplates are in place. Statement 261

This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the

Warning Never install an AC power module and a DC power module in the same chassis. Statement 1050
Warning
When stranded wiring is required, use approved wiring terminations, such as closed-loop or spade-type
with upturned lugs. These terminations should be the appropriate size for the wires and should clamp
both the insulation and conductor. Statement 1002
