First Junos OS
ReleaseDescriptionModule NameModel Number
12.2R1An SFP+ expansion module canhouse up to eight 10-gigabit
SFP+ transceivers or 1-gigabit SFP transceivers or a
combination of SFP+ and SFP transceivers. You can use the
ports on this expansion module to connect the switch to
other devices. You can also configure these ports as VCPs
and use them to connect the EX4550 switch with EX4200,
EX4500, or EX4550 switches to form a Virtual Chassis.

12.2R4A 10GBASE-T expansion module can house up to eight
100-Megabit, 1-Gigabit, or 10-Gigabit Ethernet BASE-T
connectors. You can use the ports on this expansion module
to connect the switch to other devices. You can also
configure these ports as VCPs and use them to interconnect
EX4550 switches to form a Virtual Chassis.

13.2X50-D10
NOTE: Starting
with Release
13.2X50-D15, you
can configure
QSFP+ as VCPs.
A QSFP+ expansion module has two ports, each of which
can house a 40-Gigabit QSFP+ connector. You can also
configure these ports as VCPs and use them to interconnect
EX4550 switches to form a Virtual Chassis.

QSFP+ expansion
module
EX4550-EM-2QSFP
12.2R1You can install the 128-Gigabit Virtual Chassis module in the
EX4550 switch to connect the switch to other switches in a
Virtual Chassis configuration. The Virtual Chassis module
has two dedicated VCPs, using which you can connect the
EX4550 switch with EX4200, EX4500, or EX4550 switches
to form a Virtual Chassis.

EX4550-VC-128G
Virtual Chassis
You can interconnect the EX4550 switch with EX4200, EX4500, or EX4550 switches to
form a Virtual Chassis. You can operate these interconnected switches as a single, logical
device with a single IP address.
You can interconnect a maximum of 10 EX4550 switches to form a Virtual Chassis
composed exclusively of EX4550 switches. You can interconnect EX4200 switches or
EX4500 switches or both with EX4550 switches to form a mixed Virtual Chassis that
has a maximum of 10 switches. See “Understanding EX4200, EX4500, and EX4550
Virtual Chassis Hardware Configurations” on page 135.
You can use the following ports to connect an EX4550 switch in a Virtual Chassis:
•
Dedicated VCPs on the Virtual Chassis module installed in the switch
•
SFP+ network ports and SFP+ expansion module ports configured as VCPs
