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.
