Interconnect the member switches using the dedicated VCPs on the rear panel of

switches. See Connecting a Virtual Chassis Cable to an EX4200 Switch.
NOTE: Arrange the switches in sequence, either from top to bottom or
from bottom to top (0–9).
Power on only the switch that you plan to use as the master switch (SWA-0). Do not

power on the other switches at this time.
Run the EZSetup program on SWA-0, specifying the identification parameters. See

"Connecting and Configuring an EX Series Switch (CLI Procedure)" on page 199 for
details.
NOTE: The properties that you specify for SWA-0 apply to the entire
Virtual Chassis configuration, including all the members interconnected
through VCPs..
Configure SWA-0 with the virtual management Ethernet (VME) interface for

NOTE: If you do not edit the Virtual Chassis configuration file, a
nonprovisioned configuration is generated by default. The mastership priority
value for each member switch is
You can change the role that is performed by the members by modifying the
mastership priority. See "Configuring Mastership of the EX4200 Virtual
Chassis (CLI Procedure)" on page 992. We recommend that you specify the
same mastership priority value for the desired master and backup members.
We have assigned the highest possible mastership priority to two members.
However, the member that was powered on first has higher prioritization
according to the master election algorithm. See "Understanding How the
Master in an EX4200 Virtual Chassis Is Elected" on page 898. We have allowed
the other members to use the default mastership priority, which qualifies
them to function in the role of linecard.
NOTE: If you want to change the member ID that the master has assigned
to a member switch, use the request virtual-chassis renumber command.
. The master role is selected by default.
