Uplink Modules in an EX 3200 or EX 4200 Switch
Optional uplink modules are available for all EX 3200 and EX 4200 models. Uplink modules provide either two 10-gigabit small form-factor pluggable (XFP) transceivers or four 1-gigabit small form-factor pluggable (SFP) transceivers. You can use these ports to connect an access switch to a distribution switch or to interconnect member switches of a virtual chassis across multiple wiring closets.
Figure 1 shows the SFP uplink module:

SFP uplink modules are shipped with dust covers preinstalled in the ports.
Note: If you insert a transceiver in an SFP uplink module installed in an EX 3200 switch, a corresponding network port from the last four ports is disabled. For example, if you insert an SFP transceiver in ge-0/1/3, ge-0/0/23 is disabled. The disabled port is not listed in the output of show interface commands.
Figure 2 shows the XFP uplink module which provides two 10-gigabit small form-factor pluggable (XFP) transceivers.
