You can install J-EX4200 switches in a single rack or multiple racks, or in different wiring
closets, and interconnect them to form a Virtual Chassis. Two dedicated Virtual Chassis
ports (VCPs) on the rear panel of the J-EX4200 switch are used exclusively to interconnect
J-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. To interconnect switches that are located
beyond the reach of the dedicated VCP cables, you can install the SFP uplink module or
the SFP+ uplink module and set the uplink module ports as VCP interfaces. See the
instructions for setting an uplink module as a Virtual Chassis port in the Dell PowerConnect
J-Series Ethernet Switch Complete Software Guide for Junos OS at
http://www.support.dell.com/manuals
NOTE: The interfaces for the two dedicated VCPs are operational by default.
However, if you are using the uplink module ports as VCPs, you must explicitly
set the uplink module ports to function as VCPs.
The following illustrations describe various Virtual Chassis cabling configuration examples.
NOTE: For increased availability and redundancy, we recommend that you
always configure your Virtual Chassis in a ring topology.
Figure 20 on page 78 and Figure 21 on page 78 show five switches stacked vertically in a
rack and interconnected in a ring topology using four short Virtual Chassis cables and
one long Virtual Chassis cable.
