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 11 on page 17 shows the SFP uplink module:
