CSS326-24G-2S+RM with S+RJ10 SFP 10gbe link-no link-link

Hi all,

I have just installed a S+RJ10 SFP in a CSS326-24G-2S+ running swos 2.10 to HPE OfficeConnect 1950 24G 2SFP+ 2XGT JG960A port 27 native10Gbaste-t (no transceiver).

I have had the switch for a while but the transciver is brand new.

This is connected by 20m cat6a SFTP 26AWG freshly installed to replace cat6 which only linked at 1gps.

The link status drops every 2-3 seconds but I don’t get any errors so I am not sure why it can not maintain a link.

Is it normal for the interface type to be 1m copper?

Vendor Part Number Revison Serial Date Type Temperature Voltage Tx Bias Tx Power Rx Power
SFP1 MikroTik S+RJ10 2.16 AF9403A37AF3 19-05-29 1m copper 86C 3.295V
SFP2 CISCO-MOLEX 74752-9520 09 MOC161709W6 12-04-28 3m copper

SFP1 no link no
SFP2 link on 10G yes

I can’t attach my config swg file.

Thanks

It turns out the S+RJ10 does not like 26 AWG over 20m.
