Juniper Networks EX4200 - Manual (Page 61)

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-0/0/23 is 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-slot slot number pic-slot 1 .
Figure 25 on page 35 shows the SFP+ uplink module.
