10BASE-T/The Switch has 24 auto-negotiating 10BASE-T/100BASE-TX ports 100BASE-TX Ports configured as MDIX (cross-over). These ports can be set to 10BASE-T half

duplex, 10BASE-T full duplex, 100BASE-TX half duplex, 100BASE-TX full duplex, or they can automatically detect the speed and duplex mode of a link and provide the appropriate connection. The maximum segment length is 100m (328ft) over Category 5 twisted pair cable.

As these ports are configured as MDIX (cross-over), you need to use a cross-overcable to connect to devices whose ports are MDIX-only. See “Choosing the Correct Cables” on page 30 for more information.

1000BASE-SX Port The Switch has a Gigabit Ethernet Port that provides a 1000Mbps connection to another Gigabit Ethernet device. This port uses 62.5 ∝ m or 50 ∝ m multimode fiber optic cable with MT-RJ duplex connectors.

LEDs Table 3 (overleaf) lists the LEDs visible on the front of the Switch, and their states according to color. For information on using the LEDs for problem solving, see “Solving Problems Indicated by LEDs” on page 31.
