10Gb SFP+ 10GBASE-T capabilities

Ilya_Semenov — Fri, 06 Oct 2017 23:49:00 GMT

Hello, everyone,

I've found a very intersting item in the price:

10338 10Gb SFP+ 10GBASE-T 10Gb SFP+, 10GBASE-T RJ45, 30m with Cat6a

Could somebody please tell me:

1) Does it work in all Summit's and 220's SFP+ (10Gb) ports?
2) How many 10338 10Gb SFP+ 10GBASE-T transceivers could I plug into X670 (gen1, gen2)?

Many thanks in advance,

Ilya

P.S. Does Extreme have mGig (2,5Gb, 5Gb, 10Gb) swithes at the moment?

Hi, Ilya. You can check the compatibility for all optical devices using the Hardware/Software Compatibility Matrix.

Item 10338 is compatible with most of the G2 switches: X440-G2, X450-G2, X460-G2, X620, X670-G2, X690. You can use it in up to half of the 10Gb ports. The exact wording of the usage note is Populate every other SFP+ port in system, with a maximum of half the 10Gb SFP+ ports configured with 10GBASE-T transceivers. An adjacent SFP+ port should remain unused for every 10GBASE-T SFP+ installed.

10338 is not compatible with the 200 Series switches.

Hope that helps.

Hello, Larry,

many thanks for your reply. Correct me if I have understood it wrong:

For example, in X620-8x I can use only 410GBASE-T SFP+ and 4 other optical transceivers like 10GbSR?

So, for X670-G2 I can use 24 10GBASE-T SFP+ and 24 optical transceivers like 10GbSR/LR/LRM?

Phrase "remain unused" is confusing me a little bit...

Thanks

Hi,

In that context, "remain unused" means "empty".

Hi, Stephane,

Sad, but predictable. It is because of power limitations? I know that 10GBASE-T transceivers have high power consumption...

Hi,

The 10GBase-T SFP+ are not compliant with MSA Type-II specifications, they use more power. Way more. But the main issue is that they get very hot, and that can affect adjacent transceivers. If you test, you may see them working fine, but overtime it's not so sure...

If I remember correctly, in the past I saw the same recommendations for the first-gen of 1G-ZX, then 10G-ZR (for various vendors, I was then working for a reseller).

Thanks, that is very interesting.

Hello,

Has there been any update on this matter? Or would I assume that the #10338 still maintains at half capacity of the x620, x670 switch?

RE: 10Gb SFP+ 10GBASE-T capabilities

Larry_Kunz — Sat, 07 Oct 2017 00:52:00 GMT

The limitation is still in effect.

10GBASE-T SFP+ (PN 10338) can negotiate also at 1Gbps?

Hi Daniele,

It cannot. You might want to see some more information in Pluggable Transceivers Installation Guide: https://documentation.extremenetworks.com/pluggable/GUID-55346A3F-D21F-410C-B76F-E3083DD19982.shtml

Hope that helps,

which solution you suggest to have 1g BASE-T ports on x670-G2?

RE: 10Gb SFP+ 10GBASE-T capabilities

Tomasz — Tue, 28 May 2019 16:51:00 GMT

I'd try with 10065 1000BASE-T SFP module. It was supported in X670 so should be in X670-G2 either. Extreme has to update the supported optics matrix in WW_Reference_Info available for partners (last update was some time ago...).

Have a look at this thread: https://community.extremenetworks.com/switching-routing-90302/how-to-configure-1g-baset-spf-in-summit-x670-g2-6641245#post15655800

Kind regards,
