Power Supply Module Overview

The switch operates with either one or two active power supply modules.
You can use two AC modules, two DC modules, one AC and one DC module, or one module and a blank
cover.
Note In a NEBS installation, you can use two DC modules or one DC module and a blank cover.
All switches ship with a blank cover in the second power supply slot if switches are configured with only
one power supply.
Table 3 -1 describes the supported internal power supply modules.
