One of the last four network ports on an EX3200 switch with an SFP or SFP+ uplink module installed is disabled

Problem

One of the last four built-in ports (ge-0/0/20 through ge-0/0/23 on 24-port models or ge-0/0/44 through ge-0/0/47 on 48-port models) of an EX3200 switch with an SFP or SFP+ uplink module installed in it is disabled.

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

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.

Solution

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.
