Expansion Module You can use this slot to install an Expansion Module that provides a Slot
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 27.
When an Expansion Module or Matrix 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.
Matrix Port The matrix port allows you to:
■Stack the Switch with another Switch 1100 or Switch 3300 unit using a single Matrix Cable
■Stack the Switch with up to three other Switch 1100 or Switch 3300 units, if one of the units has a Matrix Module installed.
For more information about the role of matrix port, see “Stacking Units” on page 27.
