Removing and replacing the power supply module
The RackSwitch operates with either one or two active power supply modules. You
can replace a hot-swap power supply module without powering off the switch or
disrupting switch functions.
You can operate the switch with two AC power supply modules, or one power
supply module and a blank cover. For correct airflow, both power supply slots must
be populated with either a power supply module or a blank module.
Each AC power supply module has a power cord for connection to an AC power
outlet.
Each power supply module has three LEDs that are visible from the rear panel. The
following table describes the LEDs.
