Juniper EX4200 User Manual

CAUTION: If you immediately cable both VCPs on the new switch into the
existing Virtual Chassis at the same time, a member switch that was
already part of the Virtual Chassis might become nonoperational for
several seconds. Network traffic to this switch is dropped during the
downtime.
The member switch will return to the normal operational state with no
user intervention, and normal operation of the Virtual Chassis will resume
after this downtime.

Replacing a Member Switch of a Virtual Chassis Configuration (CLI Procedure)
NOTE: This topic does not apply to Virtual Chassis Fabric (VCF) or EX8200
VirtualChassis. See Removing a Device From a Virtual Chassis Fabric or Adding
or Replacing a Member Switch or an External Routing Engine in an EX8200
Virtual Chassis (CLI Procedure).
You can replace a member switch in a Virtual Chassis without disrupting network service
on the other members. You can retain the existing configuration of the member switch
and apply it to a new member switch, or you can free up the member ID and make it
available for assignment to a new member switch.
If you want to replace a member switch of a mixed Virtual Chassis that contains EX4200,
EX4500, or EX4550 switches, see Removing an EX4200, EX4500, or EX4550 Switch From
a Mixed Virtual Chassis (CLI Procedure).
