10BASE-T/
100BASE-TX Ports
The Switch has 12 or 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” on page 36 for more information.
LEDs Table 1 (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 37.
