HP SFP to CX4

[TeleFragger]

Ok so I have a 10gb network with all Connectx-1 and Connectx-2 cards that have the CX4 plug. They work great. I am getting 10gb in Windows 10, Server 2019 and even ESXI. FreeNAS does too if I run 11.1u7 - anything newer and it doesn't see the card.

anywho…
I also run an HPE OfficeConnect 1820 24G Switch that has an SFP port. I run 2 separate networks.. 1 @ 1gb and 1 @ 10gb...

I would love to just have all machines on the 10gb be seen onto the 1gb network. How could I achieve this?

Can I get a cable, SFP to CX4 and connect one of the six ports of the CX4 to the other switch's SFP with this cable?

I want to find a cheaper cable as I don't want to drop $50... but if I had too I would but want to make sure it will work.

HPE OfficeConnect 1820 24G Switch J9980A
• 24 RJ-45 autosensing 10/100/1000 ports
• 2 SFP 100/1000 Mbps ports (min=0 \ max=2 SFP Transceivers)

HP 6400-6XG cl Switch (J8433A)

• 6 CX4 10 GbE ports (IEEE 802.3ak Type 10 Gbase-CX4)
  
  
• Duplex: full Only
  
  
• 1RS-232C DB-9 console port
  
  
• Supports a maximum of 8 10 GbE ports

I also have a Dell PowerConnect 2724 and it states..
The PowerConnect 2724 switch supports 24 GbE copper ports and has two SFP combo ports
(1000BASE-SX or 1000BASE-LX).


any help greatly appreciated on this...​

Cheap 1Gbit transceivers and a short optical cable?

Cheap 1Gbit transceivers and a short optical cable?

ok optical on one end but the other needs to be cx4... right? I don't know anything on this end.. thus the request for help

Yes that cable looks like the best option, since you have the CX4 version of that switch. Cx4 was meant for short distance direct attachment. XFP is the corresponding standard for optical.
