Virtual Chassis Module in EX4500 Switches

28
The Virtual Chassis module is installed horizontally on the rear panel of an EX4500 switch
chassis. The Virtual Chassis module has two dedicated Virtual Chassis ports (VCPs) that
can be used to interconnect the EX4500 switch with an EX4200 switch or an EX4500
switch in a Virtual Chassis configuration. The module is an offline field-replaceable unit
(FRU).
NOTE: The Virtual Chassis module is supported on EX4500 switches in Junos
OS Releases 11.1 and later.
The Virtual Chassis module comes preinstalled in the switch chassis in the
EX4500-40F-VC1-FB, EX4500-40F-VC1-BF, and EX4500-40F-VC1-DC switch models.
You must order it separately for all other switch models. See
on page 7.
NOTE: Virtual Chassis cables and Virtual Chassis cable connector retainers
are not part of the EX4500 switch's shipping configuration. If you want to
purchase these, you must order them separately.
CAUTION: Operating an EX4500 switch without the intraconnect module
or the Virtual Chassis module is not supported.
EX4500 switches running Junos OS Release 10.4R2 or later 10.4 releases will
not boot if you do not install the intraconnect module in the switch.
EX4500 switches running Junos OS Release 11.1R1 or later releases will not
boot if you install neither the intraconnect module nor the Virtual Chassis
module in the switch.
Figure 12 on page 28 shows the Virtual Chassis module.

The Virtual Chassis module has two LEDs (labeled ST and VC MODE ) on the left side
of its faceplate that indicate the status and the operating mode of the Virtual Chassis
module. See Figure 13 on page 29.
