Virtual Chassis Cabling Configuration Examples for EX3300 Switches

76
Before interconnecting EX3300 switches in a Virtual Chassis configuration, you must
consider the following factors:
The number of switches in the Virtual Chassis and their location—Starting in Junos OS
Release 12.2, you can interconnect a maximum of ten EX3300 switches to form a
Virtual Chassis composed exclusively of EX3300 switches. You can connect up to six
EX3300 switches in an EX3300 Virtual Chassis in prior Junos OS releases.
Mounting—You can mount the switches in a single rack or install them on multiple
racks. For information on the size and strength of racks, see
EX3300 Switches" on page
Cabling requirements for Virtual Chassis—You can interconnect EX3300 switches into
a Virtual Chassis through uplink ports configured as Virtual Chassis ports (VCPs). By
default, ports 2 and 3 of any uplink module are configured as VCPs.
For information on uplink module port cabling requirements, see
Specifications for EX3300 Switches" on page
Power requirements—You must plan the installation site to meet the power
requirements of the switches in a Virtual Chassis. See
Switches" on page 71.

You can install EX3300 switches on a single rack or in multiple racks, or in different wiring
closets, and interconnect them to form a Virtual Chassis.
You form an EX3300 Virtual Chassis by connecting uplink port connections as Virtual
Chassis ports (VCPs). Ports 2 and 3 are configured as VCPs on all uplink modules by
default.
The physical location of the switches in a Virtual Chassis is restricted only by the maximum
length supported for cables to connect the VCPs—in this case, the maximum length of
the uplink module cables. The maximum cable length for the uplink module cables
supported by an EX3300 switch is 6.2 miles (10 km).
The following illustrations show various Virtual Chassis cabling configuration examples.
NOTE: For increased availability and redundancy, we recommend that you
always configure your Virtual Chassis in a ring topology.
