length allowed for a virtual chassis cable is 3 meters. To connect switches that
are installed farther apart, you must configure the uplink module ports as virtual
chassis ports and use them to interconnect the switches.
NOTE: If you order virtual chassis cables separately, you should reuse the locking
covers provided with the original cable or order virtual chassis cable locking covers
also separately.
■ Clearance on the rear of the switch—You must have access to the rear of the
switch if you plan to interconnect switches to form a virtual chassis.
■ Power supply—You must plan the installation site to meet the power requirements
of the EX-series switches in a virtual chassis. The input power requirements vary
depending on the number of Power over Ethernet (PoE) ports in a switch. See
“Power Supply in EX 3200 and EX 4200 Switches” on page 27 for the power
requirements for the various configurations of PoE ports in EX 4200 switches.
