24-Port 10/100 + 2-Port Gigabit Switch with Webview and Power over Ethernet RJ-45 Ports The Switch is equipped with 24 auto-sensing RJ-45 ports. These RJ-45 ports support network speeds of either 10Mbps or 100Mbps, and can operate in half and full-duplex modes. Auto-sensing technology enables each port to automatically detect the speed of the device connected to it (10Mbps or 100Mbps), and adjust its speed and duplex accordingly. The Switch's RJ-45 ports also support the IEEE 802.3af Power-over-Ethernet (PoE) standard that enables DC power to be supplied to attached devices using wires in the connecting twisted-pair cable. Any 802.3afcompliant device attached to a port can directly draw power from the Switch over the twisted-pair cable without requiring its own separate power source. This capability gives network administrators centralized power control for devices such as IP phones and wireless access points, which translates into greater network availability. For each attached 802.3af-compliant device, the Switch automatically senses the load and dynamically supplies the required power. The Switch delivers power to a device using the two data wire pairs in the twisted-pair cable. Each port can provide up to 15.4 W of power at the standard -48 VDC voltage. To connect a device to a port, you will need to use a network cable. You will need to use Category 5 (or better) cable. For more information on twisted-pair cabling, refer to Appendix B: Cabling. The Gigabit Expansion Ports The Switch is equipped with two Gigabit Ethernet ports that have shared mini-GBIC ports, which provide for the installation of one expansion module. These ports provide links to high-speed network segments or individual workstations at speeds of up to 1000Mbps (Gigabit Ethernet). To establish a Gigabit Ethernet connection using a mini-GBIC port, you will need to install an MGBT1, MGBSX1, or MGBLH1 Gigabit expansion module and use Category 5e cabling or fiber optic cabling. For more information on fiber optic cabling, refer Appendix B: Cabling The Console Port The Switch is equipped with a serial port labeled CONSOLE (located on the front of the Switch) that allows you to connect to a computer's serial port (for configuration purposes) using the provided serial cable. You can use HyperTerminal to manage the Switch using the console port. With this and many other Linksys products, your networking options are limitless.
