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” on page 33 for more information.

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

The Switch has a Gigabit Ethernet Port that provides a 1000Mbps connection to another Gigabit Ethernet device. This port requires either a straight-through or a cross-over Category 5 cable with RJ-45 connectors at both ends.

Console 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.

Matrix Port The Matrix Port allows you to:

■

Stack the Switch 3300 SM, TM or XM with another unit in the Switch 1100/3300 family using a single Matrix Cable

■

Stack the Switch 3300 MM with up to three other units in the Switch 1100/3300 family, using up to three Matrix Cables

For more information about the role of the Matrix Port, see “Stacking Units” on page 29.

Network Configuration Examples

Switch as a

Segmentation Switch

The following illustrations show some examples of how the Switch can be used in your network.

The example in Figure 7 shows how a Switch 3300 SM/XM stack can segment a network of shared 10Mbps and 100Mbps and 1000Mbps 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. The Switch 3300 SM also provides a Gigabit Ethernet connection to a local server.

The example in Figure 9 shows how the Switch can be used for a group of users that require dedicated 10Mbps or 100Mbps connections to the desktop. The 3300 SM Switch provides a Gigabit Ethernet connection to a SuperStack II Switch 4900 in the basement and the 3300 TM Switch provides a Gigabit Ethernet connection to a local server.
