Juniper Networks EX4200, EX3200 manual SFP+ Uplink Module, On page 35 shows the SFP+ uplink module

Chapter 2: Component Descriptions

SFP uplink modules are shipped with dust covers preinstalled in the ports.

NOTE: On an EX3200 switch, if you install a transceiver in an SFP uplink module, a corresponding network port from the last four built-in ports is disabled. For example, if you install an SFP transceiver in port 2 on the uplink module (ge-0/1/3), then ge-0/0/23is disabled. The disabled port is not listed in the output of show interface commands.

The SFP uplink module requires JUNOS Software for EX Series switches, Release 9.0 or later.

SFP+ Uplink Module

SFP+ uplink modules can be used for either SFP+ or SFP transceivers. You configure the operating mode on the module to match the type of transceiver you want to use—for SFP+ transceivers, you configure the 10-gigabit operating mode, and for SFP transceivers, you configure the 1-gigabit operating mode. See “Setting the Mode on an SFP+ Uplink Module (CLI Procedure)” on page 168.

By default, the SFP+ uplink module operates in the 10-gigabit mode and supports only SFP+ transceivers. If you have not changed the module from the default setting and you want to use SFP+ transceivers, you do not need to configure the operating mode.

If the operating mode and the configured mode for an SFP+ uplink module are different, it is shown in the output of show chassis pic fpc-slotslot number pic-slot 1.
