Expansion Module
Slot
You can use this slot to install an Expansion Module; for example, a
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
Slot
You can use this slot to install a Transceiver Module. When a Transceiver
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 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.
