Installing and Connecting Summit
Power Supplies
The Summit switch models are shipped with internal power supplies that supply all the power needed
for most switch operation. To provide full power support for PoE operation, you can connect external
redundant power supplies to the Summit 300-24, the Summit 400-24p, the Summit 400-24t, and the
Summit 400-48t.
The Summit 300-48 switch is shipped with one installed 600-Watt power supply. If a switch has only
one power supply installed, you can add a second power supply to provide power load sharing and
increased support for PoE operation.
The Summit48si switch is shipped with one installed AC or DC power supply. You can add a second
power supply to provide power load sharing.
