For your Dell Switch the Dell SKU 407-BBOR is the right one.  For every other combination you have to test it and you will on your own.

@Origin3k​ No , i am asking about cisco GLC-Sx-MMD commptability with S5224F switch 

thanks 

Dell will not tell you if you can stick stuff from a competitor in one of their products.    Ask Cisco if there tranceiver will work in a non cisco switch. (waste of time.... you get it?)

What you will always loose is the funcationality to query transceiver stats/info even when connectify works.

Ages ago... they (Dell) told us for 1 and 10G foreign transceivers are not blocked by default. Thats changed with SFP28 and up.

Yes i have seen 1G HPE transceiver working in Dell swithes.

Hi,

I do not have any documented information of your exact setup that it can work. But looking only the S5224F, you would need to configure the switch port group to 10G-4x to be able to set the interface down to 1G. Here's an article on it: https://www.dell.com/support/kbdoc/en-sg/000128222/dell-emc-networking-os10-s5200-s4148u-port-won-t-come-up-due-to-wrong-port-group-profile

Here's also an alternative reference guide: https://infohub.delltechnologies.com/sv-se/l/dell-emc-smartfabric-os10-switch-configuration-guide-for-vxrail/dell-emc-powerswitch-s5248f-on-port-groups/#:~:text=In%20the%20output%20above%2C%20interface,11%2012%20%2D%20(Output%20truncated)

Once the switch port group has been configured, you will be able to execute the command to set 1G speed to the interface. 

I do not have any information on Cisco GLC-SX-MMD SFP compatibility if it could work.
