Adding a New Switch from a Different Wiring Closet to an Existing Virtual Chassis ConfigurationFollow these instructions to add a J-EX4200 switch to a J-EX4200 Virtual Chassis.To add a new switch from a different wiring closet to an existing Virtual Chassisconfiguration, you must use a long cable to connect the new member switch acrosswiring closets. You can use a port on an SFP or SFP+ uplink module, or an SFP networkport on a J-EX4200-24F switch, and a fiber-optic cable for this purpose.Before you begin, be sure you have:• Installed the uplink modules needed for the Virtual Chassis configuration.• Mounted the new switch in a rack.• If the new member switch has been previously configured, reverted its configurationto the factory defaults. For information about reverting to the factory defaultconfiguration, see the Dell PowerConnect J-Series Ethernet Switch Complete SoftwareGuide for Junos OS at http://www.support.dell.com/manuals.• Powered on the new member switch as a standalone switch and configured its uplinkmodule ports as VCPs. Otherwise, it cannot be recognized as a member switch by themaster.• If you are expanding a preprovisioned configuration, made a note of the serial number(on the back of the switch). You will need to edit the Virtual Chassis configuration toinclude the serial number of the new member switch.• If you are expanding a preprovisioned configuration, edited the existing Virtual Chassisconfiguration to include the serial number of the new member switch. You can specifythe role of the new member switch when you add its serial number in the Virtual Chassisconfiguration file. The parameters specified in the master Virtual Chassis configurationfile are applied after the new member switch has been interconnected with its uplinkVCP to an existing member switch.• Confirmed that the new, currently standalone switch is powered off.• Prepared an existing member switch for interconnecting with the new switch throughan uplink module port by configuring an uplink module port as a VCP on the existingmember switch.NOTE: After you have created a preprovisioned Virtual Chassisconfiguration, you can use the autoprovisioning feature to add memberswitches to that configuration.To add a new member switch that is going to be interconnected with the existing VirtualChassis configuration across wiring closets:1. Power on the new switch.2. Connect a laptop or terminal to the console port of the switch, or use EZSetup on thestandalone switch to specify temporary identification parameters.
