Hi Sam,   Did you every get the Starfield certs loaded onto your 1921? I'm hitting the same problem on my 1941. I had this working with the previous Duck DNS CA (Startcom) but since they changed, I've not been able to get it to work. There's a confus...

Hi Angela,I'm also in the same situation; I can't find the rackmount kit for my SG300-20. Please may I contact you to procure a replacement? Thanks,James
