Interconnecting Two Switches
To interconnect two Switches, you will need the XRN
Interconnect Module Kit (part number 3C17715). This kit
contains:
Interconnect Module Kit (part number 3C17715). This kit
contains:
Two XRN Interconnect Modules (3C17716)
One standard XRN Interconnect Cable (3C17721)
You can interconnect two Switch units that are located in
separate racks with a 5 m (16.40 ft) long Interconnect
cable (3C17722). Contact your network supplier for
further information.

CAUTION: It is important that you only plug an XRN
Interconnect Cable (3C17721 or 3C17722) into the
connector on the XRN Interconnect Module (3C17716).

The end of the Interconnect Cable that you connect to the
Switch determines the identity of the Switch. The Switch
that has the blue end of the cable connected to it will be
Unit 1. The Switch that has the yellow end of the cable
connected to it will be Unit 2.

Figure 3 Interconnecting Two Switches
To interconnect two Switches:
1 Install the Interconnect Modules into the Switch units, as
described on page 2.
2 Connect the Interconnect Cable to the Interconnect
Modules (see Figure 3).
3 Power-up the Switch units.
4 Check the LEDs on the front of the Switch and on the
front panel of the Module to ensure that the Module is
operating correctly. Refer to the “LED Function Tables” for
more information.

Always secure the Interconnect Cable to the Interconnect
Modules by tightening its securing screws.

CAUTION: 3Com recommends that you do not connect or
disconnect the Interconnect Cable when the Switches are
in use. If you do, the flow of data will be affected and
your network configuration settings may change.

LED Function Tables
You can gather information about the status of the
Module and its packet activity using the Expansion Module
LEDs on the front of the Switch (see Table 1) and the Port
LEDs on the front panel of the Module (see Table 2).
