This guide provides all the information you need to install and use a SuperStack® II Switch 1100 unit with default settings. If you want to change the way the Switch works using management software, refer to the “SuperStack II Switch Management Guide” (part number DUA1695-0BAA0x).
The guide is intended for use by network administrators who are responsible for installing and setting up network equipment; consequently, it assumes a basic working knowledge of LANs (Local Area Networks).
This guide is intended for use with both Switch 1100 models:
■3C16950 — 24 10BASE-T ports
■3C16951 — 12 10BASE-T ports
All pictures and example screens show the 24-port model, however, all procedures apply to the 24-port model and the 12-port model.
If the information in the release notes that are shipped with your product differs from the information in this guide, follow the instructions in the release notes.
Most user guides and release notes are available in Adobe Acrobat Reader Portable Document Format (PDF) or HTML on the 3Com World Wide Web site:

12 CHAPTER 1: INTRODUCING THE SWITCH 1100
About the |
The SuperStack® II system solves the problem of growth in dynamic |
SuperStack II |
network environments and provides everything you need for successful |
Switch 1100 |
workgroup networking. Much more than a collection of stackable |
|
components, the system comprises a complete, integrated architecture of |
|
modular parts that are easy to install and use. |
|
As part of this SuperStack II system, the Switch 1100 meets the challenge |
|
of modern LANs and allows you to add features and capacity as your |
|
network expands. |
■12 or 24 Ethernet 10BASE-T ports
■Two Fast Ethernet auto-negotiating 10BASE-T/100BASE-TX ports
■Matrix port for connecting units in the Switch 1100/3300 family to form a stack:
■Connect two units back-to-back using a single Matrix Cable
■Connect up to four units using Matrix Cables linked to a Matrix Module
■Slot for an Expansion Module
■Slot for a Transceiver Module (10Mbps Ethernet)
■SuperStack II architecture:
■Connects to Redundant Power System / Uninterruptible Power System
■19-inch rack or stand-alone mounting
For information about the software features of the Switch, refer to the “SuperStack II Switch Management Guide” (DUA1695-0BAA0x).

Front View Detail
Figure 1 Switch 1100 — Front view
Port Connections 10BASE-T Ports
The Switch has 12 or 24 10BASE-T ports configured as MDIX (cross-over). The maximum segment length is 100m (328ft) over Category 3, 4, or 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 30 for more information.
10BASE-T/100BASE-TX Ports
The Switch has two 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 30 for more information.

You may need this information for fault reporting purposes.
Redundant Power To protect against internal power supply failure, you can use this socket System Socket to connect a SuperStack II Advanced Redundant Power System (RPS) to the Switch. See “Connecting a Redundant Power System” on page 29.
16 CHAPTER 1: INTRODUCING THE SWITCH 1100
Expansion Module You can use this slot to install an Expansion Module; for example, a Slot 100BASE-FX Module that provides an additional high-speed link, or a
Matrix Module that provides four matrix ports for stacking Switch units together. 3Com provides a range of Expansion Modules; contact your supplier for availability. For more information about Matrix Modules, see “Stacking Units” on page 26.
When an Expansion Module is not installed, ensure the blanking plate is secured in place.
Transceiver Module You can use this slot to install a Transceiver Module. When a Transceiver Slot Module is installed, the Transceiver Module port becomes port 1 and the
port labelled 1 on the front panel becomes inactive. The Transceiver Module can provide a 10Mbps Ethernet half duplex link to the rest of your network using various media such as fiber and coaxial cabling.
When a Transceiver Module is not installed, ensure the blanking plate is secured in place.
■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, if one of the units has a Matrix Module installed
For more information about the role of the matrix port, see “Stacking
Units” on page 26.

Network Figure 4 shows the Switch 1100 in a second workgroup situation. This Segmentation II setup could be that of a small office within a large corporation, or part of
a larger corporate network. Most of the switch ports have multiple endstations.
