GS724TPv2 ProSAFE 24-Port Gigabit Smart Managed Switch with PoE+ and 2 SFP Ports Table 2. Front panel LEDs (Continued) LED Description RJ-45 lower LEDs 1-24 Off. The port is not delivering PoE. These LEDs indicate the PoE Solid green. The port is delivering PoE. status of an associated port. Solid amber. A PoE fault occurred. For more information, see PoE Troubleshooting Suggestions on page 27. Link and ACT LEDs 25F-26F Off. No SFP module link is established. Solid green. A valid 1000 Mbps link is established. Blinking green. The SFP fiber port is transmitting or receiving packets at 1000 Mbps. Switch Hardware Interfaces The following sections describe the hardware interfaces on the switch. RJ-45 Ports for 10/100/1000BASE-T Ethernet Connectivity All RJ-45 copper ports support autosensing. When you insert a cable into an RJ-45 port, the switch automatically ascertains the maximum speed (10 Mbps, 100 Mbps, or 1 Gbps) and duplex mode (half-duplex or full-duplex) of the attached device. All ports support a Category 5e (Cat 5e) unshielded twisted-pair (UTP) cable terminated with an 8-pin RJ-45 connector. To simplify the procedure for attaching devices, all RJ-45 ports support Auto Uplink technology. This technology allows attaching devices to the RJ-45 ports with either straight-through or crossover cables. When you insert a cable into the switch's RJ-45 port, the switch automatically performs the following actions: • 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 you are connecting the port to a computer) or an uplink connection (such as when you are connecting the port to a router, switch, or hub). • Automatically configures the RJ-45 port to enable communications with the attached device. The Auto Uplink technology compensates for the need to set up uplink connections while eliminating concern about whether to use crossover or straight-through cables when you attach devices. All RJ-45 ports also support Power over Ethernet (PoE+, IEEE 802.3at). The switch can supply up to 30W PoE+ to each port, with a maximum PoE power budget of 190W across all active PoE+ ports.
