The Switch has 24 auto-negotiating 10BASE-T/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-over cable to connect to devices whose ports are MDIX-only. See
"Choosing the Correct Cables"
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.
Table 3

their states according to color. For information on using the LEDs for
