Unable to get SFP28 working on a M4350-24x4V
Hello, Let me start by saying this is my first attempt to make fiber connections. I recently acquired a M4350-24x4V and am attempting to utilize the SFP28 ports. Without being able to find any ...
Hi LaurentMa,
I appreciate the quick reply. I thought the details you mentioned would be in the user manual, which is where I looked, but could not find. I missed the asterisk and corresponding footnote on page 2 of the datasheet. You pointing me to this information is helpful.
Also, I have little familiarity with switching equipment and in my naive exposure I could not imagine a situation where there would be such a limitation, i.e., in this case all optical ports must operate at the same speed. So I've approached this issue somewhat with blinders on.
My firmware needs updating as I don't see the 'FEC' columns in the port configuration page. But you said, "Don't forget you might need to configure another FEC mode." However, I don't see mention of FEC or Forward Error Correction in the user manual or data sheet for this device. Did I miss this somewhere?
I will update the firmware, try some different FEC setting[s] and report back.
Thanks. Jerry.
Hi Jerry, thank you.
The datasheet is the repository for supported features and any known limitations that can come with a product.
The technical documentation is always trying to keep up with new features (such as FEC) knowing this is general documentation based on the managed switch platform that always evolve based on new series, maintenance releases, etc.
And FEC is a setting for 25G and 100G because optics used in transceivers, NICs, and other network devices can differ hence FEC sometimes need to be configured right for specific devices. We have default Auto-FEC but in our recent firmware you will find this setting. Please upgrade to 14.0.2.17 from here: https://www.netgear.com/support/product/m4350#download
Hi LaurentMa. With the updated firmware, connecting my Intel card looks to work without issue. I didn't make any particular change to the FEC mode as one was chosen for me. In my mind this is proof enough that things are looking good.
Cheers. Jerry.
Thank you for the update, MisterBumbles
With our latest firmware, we implemented some Auto mode for FEC and I'm happy to hear that the detection with your Intel NIC went smooth, then. Cheers
