Interconnecting Two SwitchesTo interconnect two Switches, you will need the XRNInterconnect Module Kit (part number 3C17715). This kitcontains: Two XRN Interconnect Modules (3C17716) One standard XRN Interconnect Cable (3C17721)You can interconnect two Switch units that are located inseparate racks with a 5 m (16.40 ft) long Interconnectcable (3C17722). Contact your network supplier forfurther information.CAUTION: It is important that you only plug an XRNInterconnect Cable (3C17721 or 3C17722) into theconnector on the XRN Interconnect Module (3C17716).Connecting any other 9-way plug into the connector onthe XRN Interconnect Module could result in damage toyour hardware.The end of the Interconnect Cable that you connect to theSwitch determines the identity of the Switch. The Switchthat has the blue end of the cable connected to it will beUnit 1. The Switch that has the yellow end of the cableconnected to it will be Unit 2.The terms Unit 1 and Unit 2 are used simply to identifythe Switch units for management purposes only.Figure 3 Interconnecting Two SwitchesTo interconnect two Switches:1 Install the Interconnect Modules into the Switch units, asdescribed on page 2.2 Connect the Interconnect Cable to the InterconnectModules (see Figure 3).3 Power-up the Switch units.4 Check the LEDs on the front of the Switch and on thefront panel of the Module to ensure that the Module isoperating correctly. Refer to the “LED Function Tables” formore information.Always secure the Interconnect Cable to the InterconnectModules by tightening its securing screws.CAUTION: 3Com recommends that you do not connect ordisconnect the Interconnect Cable when the Switches arein use. If you do, the flow of data will be affected andyour network configuration settings may change.LED Function TablesYou can gather information about the status of theModule and its packet activity using the Expansion ModuleLEDs on the front of the Switch (see Table 1) and the PortLEDs on the front panel of the Module (see Table 2).Table 1 Switch LED Function TableTable 2 Module LED Function TableWhen using the Interconnect Module, note the following: Only one Interconnect Module may be fitted into theSwitch. The Interconnect Module is not hot-swappable. The Interconnect Module is not hot-insertable. The Interconnect Module only operates with the Switchunits listed on page 1.I NTERCONNECTING TWO SWITCHES!!!S/N: XXXX/7XXXXXXXXXS/N: XXXX/7XXXXXXXXX3C17716 XRN Interconnect Module3C17716 XRN Interconnect ModuleConsole(max) 19200,8,1,NConsole(max) 19200,8,1,NUnit 1Unit 1Unit 2Unit 2 ActivityActivityStatusStatus3C17700MAC Addr: XXXXXXXXXXXXSwitch 4900Serial No XXX/XXXXXXXXXXSUPPLY DATAV-90 - 240 Hz50/60AINPUTV27 AMax12REFER TO INSTRUCTIONMANUAL FOR CORRECTI4.5S/N: XXXX/7XXXXXXXXXS/N: XXXX/7XXXXXXXXX3C17716 XRN Interconnect Module3C17716 XRN Interconnect ModuleConsole(max) 19200,8,1,NConsole(max) 19200,8,1,NUnit 1Unit 1Unit 2Unit 2 ActivityActivityStatusStatus3C17700MAC Addr: XXXXXXXXXXXXSwitch 4900Serial No XXX/XXXXXXXXXXSUPPLY DATAV-90 - 240 Hz50/60AINPUTV27 AMax12REFER TO INSTRUCTIONMANUAL FOR CORRECTI4.5Unit 1: Blue End of CableUnit 2: Yellow End of Cable!Expansion Module Activity LEDStatus Color MeaningOn Yellow Packets are being transmitted or received on theModule.Off No color There are no packets being transmitted or received onthe Module.Expansion Module Status LEDStatus Color MeaningOff No color The Module is not installed.Flashing Yellow The Module is installed but is not recognised (faulty orunsupported).On Yellow The Module is installed but no link is present.On Green The Module is installed and a link is present.Unit 1—4 LEDStatus Color MeaningOn Green Determines the identity of the Switch when intercon-nected to another Switch to create an XRN Distrib-uted Fabric and that a link is present.Off No color A fault has occurred.Activity LEDStatus Color MeaningOn Yellow Packets are being transmitted or received on this port.Off No color There are no packets being transmitted or received onthis port.Status LEDStatus Color MeaningOn Green A link is present and the port is enabled.Off No color There is no link present.Unit 1—2 LEDStatus Color MeaningOn Green Determines the identity of the Switch wheninterconnected with another Switch.
