SummitStack-V & 1000BaseT SFPs?

[Andrew_Butterwo]

The datasheet for the Summit X440-G2 series states

"SummitStack-V allows use of standard 10Gb Ethernet cabling and optics technologies"

Does this include the pre-terminated 10GBase-CR twin-ax cables (10304, 10305, 10306 & 10307)? I am trying to cost up a small solution and need to stack four X440-G2-12p-10GE4 switches.

Hi.

can you please specify the source of this? I have not found such information in Datasheet nor in hardware installation guide.

if the 10306 is really not supported then we need to update documentation.

Thank you for cooperation.

10GB-ZR-SFPP

P/N for a 10GB 80KM SFP+

i believe above can be used for ports

[Stephane_Grosj1]

I believe this 40Km limit is because the documentation has not been updated since the introduction of ZR/DWDM SFP+.

[Zdeněk_Pala]

based on hardware installation guide = http://documentation.extremenetworks.com/summit/downloads/SummitFamily_HW_Install_EXOS21.pdf = long-distance stacking connectivity of up to 40 km

Connectivity is ok on 10GB-ZR-SFPP, but stacking can be tricky.

[Zdeněk_Pala]

Yes. You can stack stackable 440-G2 with any other stackable summit over any supported 10G interface. That include the direct attach cables.

There is a limitation that all devices must run the same version of firmware, and the cable must be supported.

There are 4 10G capable ports on The model you mentioned. Two of those ports can be used for stacking. No license is needed for stacking.
