installation.
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 Network Equipment Building System (NEBS) installation, you can use two DC modules or one DC
module and a blank cover.
All the switches ship with a blank cover in the second power supply slot if switches are configured with
only one power supply.
Table 4-1 describes the supported internal power supply modules.
