how to connect 4 switches using sfp +

[NexusXP]

Hello,

I am considering purchasing 2 SG350X-48-K9-EU and 2 SX350X-12-K9-EU. i can stack them with FC cables. it's possible ? or I can only use copper. if you have to take the cable with connector or transceivers + fiber cables

Thanks

You need use right cable as advised, you can not use any other one.

look below document :

Hi Balji,

 i can use this cable or transceiver ?

SFP-H10GB-CU1M= Copper coax 10 Gbps 1 m
SFP-H10GB-CU3M= Copper coax 10 Gbps 3 m

or this transceiver:

SFP-10G-SR= Multimode fiber 10 Gbps 26 m to 400 m
SFP-10G-SR-S= Multimode fiber 10 Gbps 26 m to 400 m

Thank you very much

Hi,

You can stack up to 4 units in a stack with a total of 208 ports managed as a single system with hardware failover. In your use case, you have to deploy so-called hybrid stack mode due to the different switch models. Your stacking ports are the XG ports. More information about how to configure stacking is available in the product administration guide:

Supported SFPs that you can use also for stacking are listed in the below table

Hi Martin,

if i understand correctly i can use these cables and these tansceivers. the switches will be either above or beside

this cable:

SFP-H10GB-CU1M= Copper coax 10 Gbps 1 m
SFP-H10GB-CU3M= Copper coax 10 Gbps 3 m

or this transceiver:

SFP-10G-SR= Multimode fiber 10 Gbps 26 m to 400 m
SFP-10G-SR-S= Multimode fiber 10 Gbps 26 m to 400 m

I therefore need the fiber cable I think. it must be at least 26 meters long, did I understand correctly? if so it is convenient to have the switches nearby

Thank you very much

Hi there,

That is correct. You can choose whichever option based on your needs - either using the SFP copper coax SFPs or any of the fibre optics SFPs. For the fibre optics connection, you will need an optical fibre cable (or optical patch cord) with LC connectors at the ends. If you have to cover greater distances the multimode fibre cable should be at least OM2 (>82m@10GE and >550m@1GE).

Regards,

Martin
