This topic provides troubleshooting information for specific problems related to interfaces
on J-EX4200 switches.
The interface on the port in which an SFP or SFP+ transceiver is installed in an SFP+
uplink module is down on page 157
The interface on the port in which an SFP or SFP+ transceiver is installed in an SFP+
uplink module installed in a J-EX4200 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 135.
