Yes, up to 10 EX4200 switches can be interconnected into a "Virtual
Chassis" using either the rear Virtual Chassis Ports (32 Gbps ingress
+ 32 Gbps egress for each of the 2 ports) with up to 5-meter VCP
cables, or using SFP, XFP or SFP+ fiber links (not sure if it works
with copper SFP, but might). You can mix/match each type of
interconnection within the same VC.
