Power Supply Modules Overview
The switch chassis has two power supply slots that operates with either one active power supply module and
a redundant power supply module. You can use two AC modules or one AC module and a blank cover. The
active and redundant modules must be of the same type.
All power supply modules have internal fans. All switches ship with a blank cover in the second power supply
slot.
The main module is field replaceable and the redundant module is hot-swappable. The redundant power supply
can also be used for extra PoE power.
The following table describes the supported internal power supply modules.

All the switches ship with a blank cover in the second power supply slot if the switches are ordered with only
one power supply module.
For information about available PoE and PoE+ requirements, see these sections the Power Supply Modules,
on page 8.
The power supply modules are autoranging units that support input voltages between 100 and 240 VAC. Each
AC power supply module has a power cord for connection to an AC power outlet. The modules use an 18-AWG
power cord.
