10BASE-T/

100BASE-TX Ports

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.

1000BASE-SX Port

(SM only)

The Switch has a Gigabit Ethernet Port that provides a 1000Mbps

connection to another Gigabit Ethernet device. This port uses 62.5 µ

µµ

µmor

50 µ

µµ

µm multimode fiber optic cable with MT-RJ duplex connectors.

1000BASE-T Port

(TM only)

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.

LEDs Table 3 (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 34.

This label shows the following:

■

The 3Com product name of the Switch

■

The 3Com 3C number of the Switch

■

The unique MAC address (Ethernet address) of the Switch

■

The serial number of the Switch

You may need this information for fault reporting purposes.

Power Socket The Switch automatically adjusts its power setting to any supply voltage

in the range 100–240V A.C. (XM, SM and MM only) or in the range

90–240V A.C. (TM only).

Redundant Power

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

The following illustrations show some examples of how the Switch can be

used in your network.

Switch as a

Segmentation Switch

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.

Switch as a Desktop

Switch

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.
