DescriptionItem
AC power source1
Redundant power supply2
The rear of the switch also has a slot for installing an optional redundant power supply. To
provide true redundancy, the second power supply should be connected to a different AC power
source from the other supply. Then, if one AC power source fails, the switch will continue to
run. Because the switch can run on a single supply, removing a redundant supply will not
interrupt switch operation.
Note:
The redundant power supply is hot swappable, but, as indicated by the caution statement on
the power supply, it must be disconnected from AC power before being installed or removed.
5.1.3 Self Test
When the switch is powered on, it performs a diagnostic self test. The entire download,
initialization, and self test process can take up to 2 minutes for a fully loaded chassis, depending
on the number and type of modules installed in the switch.
