I'm trying to connect some devices to our MS-425 unit via a copper SFP. Devices running at 1GB connect without issue, but when trying to connect an older device that only runs at 100mb it does not connect. Same of course with 10mb.
I've purchased different copper modules according to the suppliers recommendations, but the replacements act the same.
Will the 425's slow down to 100mb or am I missing something?
