Installing the Stack
44
Connecting to a Power Source
Note
It is recommended that the switches be stacked before being
connected to a power source. However, a device can be added to
the top or bottom of a stack that is ON and operating without first
powering down the stack. Be sure to stack the new device before
connecting it to a power source. All switches in a stack must be
powered ON to allow traffic to pass across the stack’s backplane.
To connect each device to a power source, perform the following
procedure:
1. Insert the power cable plug directly into the receptacle located at the
back of the device.

Power Receptacle
2. Plug the other end of the cable into a grounded, 3-pin socket.
Note
For international use, you may need to change the AC line cord.
You must use a line cord set that has been approved for the
receptacle type in your country.
3. Check the front-panel LEDs as the device is powered ON to be sure
the Power LED is lit. If not, check that the power cable is correctly
plugged in. The MGMT LED on the uppermost switch will be lit.
4. If you have purchased redundant power units, connect them to the
other devices and to an AC power source now, following the
instructions included with the package.
