Juniper EX4500 Series User Manual

NOTE: When a new uplink module is installed in the switch or an existing uplink
module is replaced with another uplink module, the switch detects the newly installed
uplink module. The switch creates the required interfaces when new transceivers
are installed in those ports.
The operating mode for an SFP+ uplink module is shown in the output of the show
chassis pic fpc-slot slot number pic-slot 1 command.
You can use the uplink module ports to connect an access switch to a distribution
switch.
Figure 17 on page 24 shows the SFP+ uplink module.
