SuperStack 3 Switch 4300 10/100/1000BASE-T
Module (3C17121) provides one Ethernet port for
connection to your network.
LEDs
SuperStack 3 Switch 4300 10/100/1000BASE-T Dual
Module (3C17122) provides two Ethernet ports for
connection to your network.
You can gather information about the status of the
Module and its packet activity using the Expansion
Module port LEDs on the front of the Switch.
The procedures described in the User Guide assume that
you have a single port Module. If you have a Dual
Module the procedures are the same, except that
procedures relating to the port apply to each port on
the Dual Module.

1
Ensure that the Switch is powered-up.
Ensure that the power supply and the backbone
connection cables are disconnected from the Switch.
Plug the RJ-45 connector on the Category 5 cable into
the RJ-45 port on the Module.
2
Undo the Module’s two captive screws with a suitable
screwdriver. Do not remove any other screws from the
Switch.

Connect the other end of the Category 5 cable to a
device that supports 1000BASE-T.

Remove the Module.
Check the LEDs on the front of the Switch to ensure
for more information.
If you are not fitting another Module immediately, you
must replace the blanking plate to ensure that dust and
debris do not enter the Switch. Replacing the blanking
plate will also help circulate cooling air through the
Switch.
MANAGING THE MODULE
When the Module is installed, you can configure it
through your Switch to add extra functionality. Refer to
the documentation that accompanies your Switch 4300
for more information.
CAUTION: Always check that each port number has the
correct parameter settings after adding, changing or
removing a Module. This is due to the method in which
the Switch dynamically assigns port numbers.
The Switch 4300 dynamically assigns port numbers to
each Module installed, so if you add, replace or remove
a Module, the port number of the other Module may
change. The port numbers allocated depend on the type
of Module; the number of Modules installed and the
slots into which they are fitted.

Installing a Dual Port Module into Slot 1
Figure 2 shows how a single port Module, inserted into
Slot 2, will be assigned a port number of 49. If you then
insert an additional dual or a single port Module into
will change. The port number originally assigned to the
Module in Slot 2 (and any port parameters you may
have set against that port number) will be re-assigned to
the Module installed into Slot 1. Similarly, if you then
remove the Module from Slot 1, the port number and
parameter settings will be re-assigned to the Module in
Slot 2.
