10BASE-T/
100BASE-TX Ports
LEDs
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”

Matrix Port
The console port allows you to connect a terminal and perform remote or
local out-of-band management. The console port uses standard null
modem cable and is set to auto-baud, 8 data bits, no parity and 1 stop
bit.
The Matrix Port allows you to:
■
Stack the Switch with another unit in the Switch 1100/3300 family
using a single Matrix Cable
■
Stack the Switch with up to three other units in the Switch 1100/3300
family, when one of the units is a Switch 3300 MM unit
For more information about the role of the Matrix Port, see “Stacking
Units” on page 26.

The example in Figure 3
shows how a Switch 3300 XM stack can
segment a network of shared 10Mbps and 100Mbps connections. There
is a 10/100 shared segment on each floor, and these segments are
connected to the Switch which is positioned in the basement.
