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 (CAT6) ports.
Have I missed a step?

Re: Connect M5300 & S3300 via SPF
Hi autoitaus,
It seems that you are having issues connecting a DAC to your switches. May you be able to check if both of the ports are set as "Stack" and not as "Ethernet"? Go to System > Stacking > Advanced > Stack-port Configuration.
Please let me know if this will work.

Re: Connect M5300 & S3300 via SPF
Hi John,
I'm not trying to create a stack, just a normal uplink.
The SPF ports in question (Port 46 on the M5300) cannot be configured for a stack anyway. The only ports that support a stack on the M5300 are 49,50,51,52

Re: Connect M5300 & S3300 via SPF
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.

Re: Connect M5300 & S3300 via SPF
Hi John
Yes it is set to Ethernet on both switches. Models are:
M5300-52G ProSafe 48-port
S3300-52X ProSAFE 48-Port

Re: Connect M5300 & S3300 via SPF
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.

Re: Connect M5300 & S3300 via SPF
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

Re: Connect M5300 & S3300 via SPF
Hi Laurent,
Thanks for that information, much appreciated.
According to this document, there are 4 x 10GB ports on the front (2 dedicated and 2 shared) but I cannot find anywhere that specifically says which ports these are. Are you able to let me know the four port numbers that are 10GB ?

Hm, the table on top of the specs says:
M5300-52G3
- 48 x 10/100/1000 Base-T RJ45 ports
- 4 x shared 100/1000X Fiber SFP ports
- 2 x shared 1000/10GBase-X Fiber SFP+ ports

Only ports 49 and 50 are 10Gb ports:

That's not what the data sheet says

Re: Connect M5300 & S3300 via SPF
Thanks, @schumaku
@autoitaus, in this table, we show "FRONT" and "BACK" at the top.
On the front of the switch, there are two shared 10G ports (port 49 and port 50) that can be each used either with copper (10GBASE-T RJ45) or with fiber (10GBASE-X SFP+).
On the back of the switch, there are two other 10G ports (port 51 and port 52) that can be available when inserting one or two 10G port modules in these rear bays.
For instance, an AX743 port module in the first rear bay will bring a port 51 being a 10GBASE-X SFP+ garage. If you want to use it for your SFP+ DAC uplink connection to another switch, you just need to configure the port 51 as an Ethernet port first (GUI, System / Stacking / Advanced / Stacking Ports) since by default, the ports 51-52 in rear bays were preset for stacking in M5300 series. The running mode will remain "stacking" after you change the configuration, it will require a reboot to see the running mode changed to "Ethernet". Then you will see a link up to our other switch using an SFP+ DAC cable.
I hope this helps,
Regards

Re: Connect M5300 & S3300 via SPF
Sorry for the confusion caused, I've ignored the to back ports in my list above, because these are by default used for stacking.

Re: Connect M5300 & S3300 via SPF
Hi Laurent,
With all due respect, that is not what your data sheet says. It is very very clear that the FRONT has 2 x Shared 10GB Ports and 2 x Dedicated 10GB Ports and the REAR has 2 x *additional* I/O Bays - see below.
Are you saying that your data sheet is incorrect and that the FRONT does NOT have 2 x Dedicated 10GB Ports and 2 x Shared 10GB Ports ?

Re: Connect M5300 & S3300 via SPF
Hi @jiska78
Thank you for your question and I am sorry to see some confusion here. Maybe with the word "shared", namely here. I confirm the datasheet is correct, and you are correct too.
Based on this specific table in the datasheet, the two 10GBASE-X SFP+ fiber ports are shared with the two 10GBASE-T RJ45 ports. You show two combo ports, in other words, being two copper ports combo with fiber ports. It means we can use either copper or fiber at a time on each pair.
Maybe the Tech Spec section of the datasheet can help as well, it starts with Physical Interfaces and port counts:

Re: Connect M5300 & S3300 via SPF
The real confusion is coming from two points - the datasheet does show
- M5300-52G3 is a “48 + 4x10GbE” version, Layer 3 (plain text)
- "I/O Ports" listed, but not the effective kit as delivered with the stacking module in place
@LaurentMa it's really not perfectly clear.

Re: Connect M5300 & S3300 via SPF
Well, actually, the point for me is that you're violated Australia Consumer Law by advertising that a product can do something, but then when I've bought it, it hasn't been able to do what you claimed it could. That means I'm entitled to a full refund for the product, so I'll contact Netgear for an RMA.

There are at least to screenshots in this thread clearly showing the SFP+ are shared with the 10GBase-T IMHO:
Front
- 2 x Auto-sensing RJ45 100/1000/10GBase-T
- 2 x Auto-sensing SFP+ ports 1000/10GBase-X (shared with the two 10GBT)
Back
- 2 x 10 Gigabit I/O bays
Re-thinking after a night, the "M5300-52G3 is a “48 + 4x10GbE” is correct - there are four 10GbE capable interfaces in total, two shared 10GBase-T/SFP+ (plus the two 10GbE I/O slots).
That will be hard to argue away, even downunder.
The Netgear ProSAFE 10GBASE-T RJ45 I/O MODULE (AX745-10000S) are less than 100 USD from Amazon North America, the SFP+ variant (AX743-10000S) is even less, so kind of affordable for adding two 10GBase-T resp. two SFP+ interfaces.
PS. @LaurentMa ... something odd with the European pricing, in Switzerland these are listed in the range of about 340...370 CHF (around 350 Euro!) - that's to much for both model variants.
