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.
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.
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.
