Step Task (Continued) 3 Verify that your terminal's settings match the default settings on the console port, as listed above. FTOS does not have the ability to enable you to set a higher speed on the console port. To make other console port configuration changes, such as setting the console port timeout or setting up access security, use the line console command in CONFIGURATION mode of the CLI. Connecting S25V Ethernet Ports with PoE The copper ports (ports 1 through 24) in the S25V are able to deliver power to connected powered devices that follow the IEEE 802.3af specification for Power over Ethernet (PoE). For delivering PoE, use the same Cat. 5 cables and RJ-45 connectors that you use for non-PoE connections. The PoE pinout is shown in Figure 25. Figure 25 RJ-45 PoE pinout The internal AC 470 watt power supply will limit PoE power to 320 watts if the switch requires power for other uses, and the default PoE configuration limits PoE power to 288 watts. As described in Power over Ethernet (PoE) Support on page 17, you can raise that limit with an external power supply running in load-sharing mode and with certain FTOS commands. So, while each port can provide more than the maximum of 15.4 watts required by the IEEE 802.3af specification, the available power to a particular port is subject to the power budget of the switch and to the power already allotted to other ports. You can use the CLI to prioritize the allocation of power per port and to raise the power budget threshold. For more on CLI commands that control PoE, see the PoE chapters of the FTOS Configuration Guide for the S-Series and the FTOS Command Reference for the S-Series. 38 Installing Ports
