Troubleshooting Network Interfaces on EX4200 Switches

OS for EX Series Ethernet Switches, Release 10.4
The last four built-in ports use the same ASIC as the SFP uplink module. Therefore, if
you install a transceiver in an SFP or SFP+ uplink module installed in an EX3200 switch,
a corresponding base port from the last four built-in ports is disabled.
If you need to use the disabled built-in port, you must remove the transceiver from the
SFP or SFP+ uplink module. Alternatively, you can install an XFP uplink module instead
of an SFP or SFP+ uplink module. There is no conflict between the built-in network ports
and the ports on the XFP uplink modules.
The interface on the port in which an SFP or SFP+ transceiver is installed in an SFP+
uplink module installed in an EX3200 switch is down.
When you check the status with the CLI command
user interface, the disabled port is not listed.
By default, the SFP+ uplink module operates in the 10-gigabit mode and supports only
SFP+ transceivers. The operating mode for the module is incorrectly set.
Either SFP+ or SFP transceivers can be installed in SFP+ uplink modules. You must
configure the operating mode of the SFP+ uplink module to match the type of transceiver
you want to use. For SFP+ transceivers, configure the 10-gigabit operating mode and for
SFP transceivers, configure the 1-gigabit operating mode. See "Setting the Mode on an
SFP+ Uplink Module (CLI Procedure)" on page 1343.
