Power Connectors
The 8100S Series switches have two AC or DC power supply sockets on
the back panels, except for the AT-8100S/24C Switch, which has one AC
power supply socket. The 8100L Series switches have one AC power
supply socket.
AC switches are powered on or off by connecting or disconnecting the
power cords. DC switches are powered on or off by energizing or
de-energizing the DC circuit breakers to which the switches are connected
in the wiring closet.
