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:

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.

Hi schumaku 

I will not argue with you, thank you for your help before. I hope this thread was useful to the Community and jiska78 

For convenience, let me display some more information from the M5300 datasheet:

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.

Can you please show me where it says that the RJ45 10GB Ports are "Shared"

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.
