Power Supply Modules
The 24-port and 48-port switches are powered through one or two internal power supply modules.
The switch has two internal power supply module slots. You can use two AC modules, two DC modules,
a mixed configuration of one AC and one DC power supply module, or one power supply module and a
blank cover. The switch can operate with either one or two active power supply modules.
Table 1-1 shows the default power supply modules that ship with each switch model. All power supply
modules (except the blank covers) have internal fans. All switches ship with a blank cover in the second
power supply slot if switches are configured with only one power supply.
Caution Do not operate the switch with one power supply module slot being empty. For proper chassis cooling,
both the power supply module slots must be populated, or with either a power supply or a blank cover.
