14 CHAPTER 1: INTRODUCING THE SWITCH 3300 XM, SM, TM, MM
10BASE-T/ The Switch has 24 auto-negotiating 10BASE-T/100BASE-TX ports 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 The Switch has a Gigabit Ethernet Port that provides a 1000Mbps
(SM only) connection to another Gigabit Ethernet device. This port uses 62.5 m or 50 m multimode fiber optic cable with MT-RJ duplex connectors.
1000BASE-T Port The Switch has a Gigabit Ethernet Port that provides a 1000Mbps
(TM only) 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.

The Switch has failed its Power On Self Test. |
|
Off |
The Switch is not receiving power. |

Power Socket
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.
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 To protect against internal power supply failure, you can use this socket System Socket to connect a SuperStack Advanced Redundant Power System (ARPS) to the Switch. See “Connecting a Redundant Power System” on page 32.
Switch — Rear View Detail 17
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.

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 The example in Figure 9 shows how the Switch can be used for a group Switch 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.
