How To Interconnect
Units
To interconnect any two Switch 4900 Series or Switch 4050/4060 units
you will need to order the XRN Interconnect Module Kit (3C17715). The
kit consists of two XRN Interconnect Modules and an Interconnect Cable.
Both Switches must have an unused expansion slot to allow an
Interconnect Module to be fitted.

supplier. For illustrations and information on how to install the XRN
Interconnect Kits, refer to the user documentation that accompanies
these Kits.
Rules For
Interconnecting Units
This information is also provided in the user documentation that
accompanies the XRN Interconnect Kits.
■ The maximum number of Switch units that can be interconnected is
two.
■ XRN Interconnect Modules are NOT hot-swappable or hot-insertable.
Ensure that the Switch is powered off before inserting or removing an
Interconnect Module.
■ Only 3Com XRN Interconnect Cables can be used to connect two
Interconnect Modules.
■ It is not possible to interconnect the Switch 4900 Series and Switch
4050/4060 units with any other 3Com device.
■ 3Com strongly recommends that you upgrade all Switches to be
interconnected to the latest software agent.
■ 3Com recommends that you initialize a Switch unit that has previously
been used elsewhere in your network before you interconnect to an
