Distance Between Virtual
Chassis Members

NOTE: With separately ordered Virtual Chassis cables, you can use the cable connector retainers
provided with the original cable; you can also use separately ordered Virtual Chassis cable
connector retainers.

Virtual Chassis Cabling Configuration Examples for EX4200 Switches

You can install EX4200 switches in a single rack or multiple racks, or in different wiring closets, and
interconnect them to form a Virtual Chassis. There are two dedicated Virtual Chassis ports (VCPs) on the
rear panel of the EX4200 switch that are used exclusively to interconnect EX4200 switches as a Virtual
Chassis. The physical location of the switches in a Virtual Chassis is restricted only by the maximum length
supported for cables to connect the VCPs. The maximum cable length for interconnecting the dedicated
VCPs is 5 meters. If you want to interconnect EX4200 switches that are located beyond the reach of the
dedicated VCP cables, you can install the XFP uplink module, the SFP uplink module, or the SFP+ uplink
module and set the uplink module ports as VCP interfaces. See Setting an Uplink Port on an EX Series or
QFX Series Switch as a Virtual Chassis Port.

Details
You must order these cables separately for EX4200,
EX4500, and EX4550 switches, including EX4500
switches that are shipped with a preinstalled Virtual
Chassis module.
To interconnect EX4200 switches that are installed
farther apart than 5 m, you must configure the SFP,
SPF+, or XFP uplink module ports or the SFP network
ports in the EX4200-24F switch as VCPs and use them
to interconnect the switches.
To interconnect EX4500 switches that are installed
farther apart than 5 m, you must configure either the
uplink module ports or the SFP+ network ports as
VCPs and use them to interconnect the switches.
To interconnect EX4550 switches that are installed
farther apart than 5 m, you must configure either the
expansion module ports or the network ports as VCPs
and use them to interconnect the switches.
