Powering on AC Switches
To power on the stack for the first time, connect the power cords to the
connectors on the back panels and to the appropriate power sources. All
of the models have two power supplies with separate connectors. The
only exception is the AT-8100S/24C Switch, which has only one power
supply.
Figure 37. Plugging in the AC Power Cords
Consider the following items as you power on the stack:
You should power on the member switches first, wait a few
seconds, and then power on the master switch. The master switch
is the unit with the lowest stack ID number.
You can protect a switch from a power circuit failure by connecting
its two power cords to power sources that are on different circuits.
The AT-8100S/24POE Switch supports 370 watts of PoE only
when both internal power supplies are connected to power
sources. The switch haS a PoE budget of 185 watts if only one
power supply is functional. For background information, refer to
“Power Supplies” on page 48.
For the power specifications, refer to “Power Specifications” on
page 132.
