AT-8000/8POE Layer 2 Fast Ethernet Switch Installation Guide 10/100/1000 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 RJ-45 Uplink over the connection. Port 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
