Five-slot Chassis with Redundant Power Supply (model 4450R)
A Passport 4400 unit with the redundant power supply option contains a
subassembly that houses extra power supplies. It provides an extra power supply
in the event that one of the original four fails.
Two indicator lights that monitor the power supplies are located at the top right
side of the front bezel. The triangle-shaped (green) indicator is lit when all power
supplies are working properly. The rectangle-shaped (red) indicator lights up
when there is a problem with one or more power supplies in the unit, or when too
many power supplies are connected (refer to Table 10-1).
