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.
Removing an ac power supply module
To remove a power supply module, complete the following steps:
1. Remove the power cord from the power connector.
2. Press the release latch on the left side of the power supply module, and slide
