You can interconnect a maximum of 10 J-EX4200 switchesthrough the dedicated 64-Gbps Virtual Chassis ports (VCPs) or the uplink module portsconfigured as VCPs to form a Virtual Chassis. All J-EX4200 switch models support VirtualChassis, and you can interconnect different models, offering a range of port configurations,within the same Virtual Chassis.The Virtual Chassis configuration includes designation of a master switch and a backupswitch, with all other switches in the configuration designated as "line card" role switches.Virtual Chassis operation is managed through the master switch. Each switch in theVirtual Chassis is assigned a unique identifier that is displayed on the switch LCD.RelatedDocumentationFor information about Virtual Chassis components, see the Dell PowerConnect J-SeriesEthernet Switch Complete Software Guide for Junos OS athttp://www.support.dell.com/manuals.•• Planning the Virtual Chassis on page 76• Virtual Chassis Ports Connector Pinout Information for J-EX4200 Switches on page 49• Virtual Chassis Cabling Configuration Examples for J-EX4200 Switches on page 7775
