EX 4200 and EX 3200 2-Port 10G XFP Uplink Module (optics sold separately)

EX 4200 and EX 3200 2-Port 10G XFP Uplink Module (optics sold separately)

EX 3200 and EX 4200 switches support three types of uplink modules:

    * SFP uplink module—Provides four ports for 1-gigabit small form-factor pluggable (SFP) transceivers.
    * SFP+ uplink module—Provides two ports for 10-gigabit small form-factor pluggable (SFP+) transceivers when configured to operate in 10-gigabit mode or four ports for 1-gigabit small form-factor pluggable (SFP) transceivers when configured to operate in 1-gigabit mode.
    * XFP uplink module—Provides two ports for 10-gigabit small form-factor pluggable (XFP) transceivers.   

You can use the optional uplink module ports to connect an access switch to a distribution switch. You can also use these ports to connect members of a virtual chassis across multiple wiring closets.
When connecting uplink module ports, you can install an SFP uplink module at one end and install an SFP + uplink module configured to operate in the 1-gigabit mode at the other end. Likewise, you can install an XFP uplink module at one end and install an SFP + uplink module configured to operate in the 10-gigabit mode at the other end.

XFP uplink modules are shipped with a dust cover preinstalled in one port.
The XFP uplink module requires JUNOS software for EX-series switches, Release 9.0 or later.
