Chapter 1: Overview

AT-PWR06 Power Supply Module

The AT-DC2552XS L2 Data Center Switch is powered by one AT-PWR06 power supply module. A second AT-PWR06 power supply module may be installed for redundancy. The power supply module has an AC connector on the power supply module panel and is installed by the user in slot PS1 or slot PS2. The location of these slots is shown in Figure 2 on page 20.

When two power supplies are installed and operating, only one power supply is active at a time. The second power supply operates in a redundant state and is automatically activated by the switch if the active power supply loses power or fails. The change over is instantaneous and has no effect on the Ethernet data being passed through the chassis.
