How To Interconnect
Units
Rules For
Interconnecting Units
You can interconnect your Switches to create an XRN Distributed Fabric
using one of the following methods:
XRN Interconnect Kit (3C17715) — consists of two XRN Interconnect
Modules and a 1 meter (3.28 feet) Interconnect cable. Should you
wish to connect two Switch units together that are located in separate
racks you can obtain a 5 meter (16.4 feet) Interconnect cable
(3C17722). Contact your network supplier for further information.
SuperStack 3 Switch 4900 Family GBIC Module (3C17714) operating
in XRN mode. Using the GBIC Module in this way means you can have
an Fabric Interconnect extended up to 70 Km (43.5 miles) between
the units, if necessary (dependant upon GBIC transceiver type).
For a detailed description of how to create an XRN Distributed Fabric
using either of these methods, please refer to the user documentation
that accompanies the Kit or the GBIC Module. The documentation can
also be located on the 3Com Web site.

This information is also provided in the user documentation that
accompanies the XRN Interconnect Kits or GBIC module.
The maximum number of Switch units that can be interconnected is
two.
Both Switches must have an unused expansion slot to allow an
Interconnect Module or a GBIC Module to be fitted.
The XRN Interconnect Module and the GBIC Module are NOT
hot-swappable or hot-insertable. Ensure that the Switch is powered
off before inserting or removing a Module.
