I own a HP DL380 Gen10 with a HPE Ethernet 10/25Gb 2-port 640SFP28 (817753-B21) network card. The thing is that now I need 1gbps RJ45 connectors and those are not (strangely) present in the server. There seems to be no SFP+ adapters including RJ45 connectors (at least not listed at HP docs).
My question is regarding compatibility, in general:
- Can I use non-HP SFP+ with this server?
- Can I use SFP transceivers on a SFP28 connector? I understand I can use SFP on SFP+ ports and SFP+ connectors on SFP28 ports so I would suppose this would be also true for SFP-SFP28 but something tells me don't do it.
What are you experiences with this issue? SFP* are way cheaper than purchasing a new PCIe network card.
Thanks in advance, Jose
