Installing or replacing a power supply module
The RackSwitch G8264CS 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.
