10BASE-T/

100BASE-TX Ports

LEDs

The Switch has 24 auto-negotiating 10BASE-T/100BASE-TX ports configure d 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 Ports

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 ports allow you to stack the Switch with up to three other units from the Switch 1100/3300 family using three Matrix Cables.

For more information about the role of the Matrix ports, see “Stacking

The following il lustra tions show some ex amples of how th e Switch can be used in your network.

The example in Figure 3

shows how a Switch 3300 MM 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.
