10/100/1000
RJ-45 Uplink
Port
The 10/100/1000Base-T uplink port is a backup for the SFP uplink port. If
the SFP’s fiber connection fails, the 10/100/1000Base-T uplink port takes
over the connection.
SFP Port
The SFP port, port 9, can operate in place of its twisted pair port
equivalent to provide fiber optic uplink connectivity. When an SFP is
inserted in the SFP port and a fiber optic cable is connected, the
corresponding twisted pair port is disabled.
RS-232 Console
Port
The RS-232 console port uses the management cable supplied with the
switch. Through the console port you can connect to the switch and use
the menus-based AT-S81 management software user interface.
