This is not supported.

http://www.juniper.net/documentation/en_US/junos13.2/topics/task/configuration/virtual-chassis-ex4300-configuring.html

In an EX4300 Virtual Chassis, you interconnect the EX4300 switches by using uplink ports configured as Virtual Chassis ports (VCPs). The QSFP+ uplink ports, which support 40Gbps speeds and can connect switches that are up to 492 feet (150 m) apart, are configured as VCPs by default. The SFP+ uplink ports, which support 10Gbps speeds and can connect switches that are up to 6.2 miles (10 km) apart, can be configured into VCPs.

If this worked for you please flag my post as an "Accepted Solution" so others can benefit. A kudo would be cool if you think I earned it.
