Only one SFP+ working on Switch M4250-40G8XF-PoE++
Hi, I have an issue concerning the SFP+ ports on my Switch. My firmware is up to date, but when I plug an SFP+ in the port 41, everything is working fine, but nothing works for the ports 42 to 48...
Hi,
Thank you for the quick answer. I'm sorry about the lack of information, I will send the tech-support file to the specified mail address.
To make it simple, I got a device connected on port 41, it's working fine, the led is lit, etc. I take the cable and the SFP+ module out of the port 41 and plug it into port 42, and now it doesn't work anymore, no led, nothing.
Everything is in automatic mode, maybe I should do a factory reset and try again. (I just need one VLAN in this configuration, and it is configured with the NDI4 profile)
Best regards,
Maxence
Thank you. I would reconfigure and delete that NDI VLAN. Instead, edit VLAN 1 (default VLAN) and apply the NDI template to it. Maybe your problem was the Management VLAN being down. If you need only one VLAN, you can use the Default VLAN 1 instead and apply the AV template you want to it.
Your Tech Support files will tell better to us, though!

- The same exact thing on the same model switch happened to me tonight after I updated firmware from .19 to .26. Spent three hours trying to figure out what was wrong. Downgraded firmware and voila, everything worked normal again.
