FS700TS Hardware Installation Guide Table 3-3. System LEDs (continued) LED Power LED MAX POE LED Designation • Off - Power is disconnected. • Solid Green - Power is supplied to the switch and is operating normally. • Solid Yellow - Indicates that less than 180W of PoE power is available. • Flashing Yellow - Indicates that the PoE MAX LED was active in the previous two minutes. • Off - There is at least 7W of PoE power available for another device. Device Hardware Interfaces This section provides information for the following hardware interfaces: • "RJ-45 Ports" • "SFP GBIC Module" • "Factory Defaults Button" RJ-45 Ports RJ-45ports are auto-sensing ports. When inserting a cable into an RJ-45 port, the switch automatically ascertains the maximum speed (10 or 100 or 1000 Mbps) and duplex mode (half- or full-duplex) of the attached device. All ports support only Unshielded Twisted-Pair (UTP) cable terminated with an 8-pin RJ-45 plug. To simplify the procedure for attaching devices, all RJ-45 ports support Auto Uplink. This technology allows attaching devices to the RJ-45 ports with either straight-through or crossover cables. When inserting a cable into the switch's RJ-45 port, the switch automatically: • Senses whether the cable is a straight-through or crossover cable. • Determines whether the link to the attached device requires a "normal" connection (such as when connecting the port to a PC) or an "uplink" connection (such as when connecting the port to a router, switch, or hub). • Configures the RJ-45 port to enable communications with the attached device, without requiring user intervention. In this way, the Auto Uplink technology compensates for setting uplink connections, while eliminating concern about whether to use crossover or straightthrough cables when attaching devices. 3-25 v1.0, September 2007 Physical Description
