The interface on the port in which an SFP or SFP+ transceiver is installed in an SFP+ uplink module is down

Problem

The interface on the port in which an SFP or SFP+ transceiver is installed in an SFP+ uplink module installed in an EX3200 or EX4200 switch is down.

When you check the status with the CLI command show interfaces ge- or with the J-Web user interface, the disabled port is not listed.

Cause

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.

Solution

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).
