3. Connect the power cables.
For AC-powered units, connect the power cable to the AC power connector on the back of the
switch. Then connect the power cable to an AC power socket.
For DC-powered units, see Connecting DC-Powered Switches to a Power Source on page 329.
4. Connect the switch to the external (redundant) power supply, if applicable. For instructions to install
and connect external power supplies, see Installing External Power Supplies on page 364.

Note
For DC-powered switches, do not use this procedure. Instead, see Connecting DC-Powered
Switches to a Power Source on page 329.
To power up an Extreme Networks AC-powered switch, do the following:
1. Connect the AC power cord to the AC power input socket on the switch and an AC power outlet.
2. If applicable, attach the cable from your redundant power supply (RPS) into the switch’s redundant
power supply receptacle.
3. When power is connected, verify that the PSU LED and RPS LED (if applicable) turns green.
When both LEDs have turned green, follow the instructions in Connecting Network Interface Cables on
page 359.
If the PSU and RPS LEDs do not turn green, see the Switch LEDs topic for your switch model (in Summit
Switches on page 24) for troubleshooting information.
