Transceiver Module Ports
A slot on the front of the Switch 1005 allows you to install any of the
Transceiver
M
odules available for this product. You can find more
details in
“Transceiver Module slot”
on page1-18.
The Backbon e Port
The MSH Switch 1005 requires that the port
connecting
it to the rest of
your network is configured as a
backbone port
. This is the port to which
all frames arriving at a switch por t with an unknown destination
address will be forwarded. Addresses received on the backbone port
are not stored in the
switch database of the
Switch 1005.
When you first install a Switch 100 5 into your MSH chassis, it will
configure its backbone port to be the first Fast Ethernet port it finds
either on the Switch, or on the
E
xpansion
M
odule if fitted. You can
change your designated backbone port to be any switch port (internal
or external). Changing the default backbone port is described in
“Specifying the Backbone Port”
in Chapter 3.
You
can
only have one backbone port per Switch 1005, unless you
have implemented multiple VLANs on one Switch; in this case you
can
configure one backbone port per VLAN. You can find more information
about VLANs in
Chapter 4
.
Adding an Expansion Module
The MSH Switch 1005 also has provision for installing an Expansion
Module. The Expansion Module has three slots for installi ng any
combination of the
Transceiver Module
s described in
“Transceiver
Module slot”
on page 1-18.
