5-slot Chassis with Redundant Power Supply
A 5-slot Passport 4450 chassis with the redundant power supply option contains
a subassembly that houses an extra power supply in the event that one of the
original four fails. This unit is available in either AC and DC power; the figure
below shows an AC unit.
Figure 9-3. 5-slot Passport 4455 with Redundant Power Supply
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 (see Table 9-1 on page 9-5).
