Connect M5300 & S3300 via SPF
I have a direct attached SPF cable (AXC761) and have plugged it in from a M5300 to a S3300 switch. Both ends are showing as link down and there is nothing plugged in to the corrosponding ethernet (CA...
My apologies for the confusion.
May I know the exact model number of your M5300? Have you checked the S3300 if the port is set to "Ethernet"? It seems that this device has a lifetime chat support, I suggest you to open a ticket on NETGEAR support and please let them know the status of your switch so that your issue will be addressed immediately.

Hi John
Yes it is set to Ethernet on both switches. Models are:
M5300-52G ProSafe 48-port
S3300-52X ProSAFE 48-Port
FYI - Netgear Support Chat is down
I can't believe that no-one knows how to uplink two switches with SPF?
Netgear is the worst brand I've ever experienced.
Will never sell it again.
Hi autoitaus
I am sorry about your issue. I am also sorry you didn't make it easy for anyone to understand your issue, it took too much guess to read your posts.
The M5300-52G switch (GSM7252S) has its last 4 copper 1000BASE-T RJ45 ports (45-48) combo ports, they are shared with the last 4 1000BASE-X SFP fiber ports. The port 46 you are mentioning must be the SFP shared 1G port. You are trying to use a 10G SFP+ Direct Attach Cable (AXC761) with this 1G SFP port. This can't work, the DAC cable is 10G SFP+. There can't be any link with any SFP+ fiber DAC or transceiver when connected to a 1000BASE-X SFP garage port. This, for any brand and any type of switch. There is no upward capability with fiber in general, only backward capability if any. The 1000BASE-X SFP fiber ports can only connect 1G SFP transceivers or DAC, or 100FX if supported - but never ever 10G SFP+ modules.
Your S3300 switch on the other side has 10GBASE-X SFP+ ports. This port can be ok with either 10G SFP+ transceivers/DAC or 1G SFP transceivers (backward compatibility is supported on these models).
For your uplink between these two switches, if you want to continue with the AXC761 10G SFP+ SFP+ DAC cable, you should use a 10GBASE-X SFP+ fiber port on your M5300-52G switch, maybe the shared ports 49-50 on the front. If you really want to use a 1G port on this switch, you should revert to 1G fiber transceivers on both ends (like AGM731F and MMF patch cord). Or a 1G grade DAC cable made of SFP connectors for 1G connections (that will have to be third-party, as NETGEAR doesn't carry such DAC cable in its portfolio).
I hope this helps,
Regards
