SFP Configuration Troubles

Omnia hardware Omnia HW help

Hi Everyone,

New to the forum and a bit of a noob. I recently purchased the FS Generic Compatible 2.5GBASE-T SFP Copper RJ-45 and attempted the install based on the instructions in the linked post - FS 2.5GBase-T SFP not working with Turris Omnia - #9 by ju2wheels.

My issue is, after reboot, the sfp module is recognized by dmesg and is attempting to establish a link, but it never gets past the link configuration:

[ 7.900855] sfp sfp: Host maximum power 3.0W
[ 8.228454] sfp sfp: module FS SFP-2.5G-T rev 1.0 sn G2220759545 dc 220607
root@turris:~# dmesg | grep -i -e sfp -e eth2
[ 1.877194] mvneta f1034000.ethernet eth2: Using device tree mac address d8:58:d7:01:0d:a9
[ 7.900855] sfp sfp: Host maximum power 3.0W
[ 8.228454] sfp sfp: module FS SFP-2.5G-T rev 1.0 sn G2220759545 dc 220607
[ 8.237811] mvneta f1034000.ethernet eth2: switched to inband/2500base-x link mode
[ 12.045476] mvneta f1034000.ethernet eth2: configuring for inband/2500base-x link mode

Any suggestions on how to fully establish the link? Any help is much appreciated.

It worked out the box for me once I switched the device boot tree dbt file. My cable modem has a special 2.5GB port on it that I connected it to with a CAT6e and once I booted up the Omnia, it was able to connect automatically without anything further from my end. Not sure what else to recommend trying here.

Yeah, I’m at a bit of a loss here myself. My modem is a Motorola mb8611b and is also setup with a 2.5G port, but I’m using a cat6a cable; maybe that’s it? Although, I think the cable should support those speeds without a problem.

I might have to give a full reset a try and start from scratch. I’m on TOS 6.3.1, btw.

There is no Cat6"E". Either Cat5.e, Cat6 or Cat6.a (,…)

Cat5.e and higher are all capable of 802.3bz (2500/5000BASE-T ⇨ 2.5GBASE-T and 5GBASE-T - Wikipedia)

Do you need Ethernet cable?
