Juniper EX3200 Hardware Guide

The interface on the port in which an SFP or SFP+ transceiver is installed in an SFP+ uplink
module is down
Problem Description: 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.
Symptoms: 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 typeof 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+ or SFP+ MACSec Uplink Module (CLI Procedure).
