DR4100 set up SNMP

Greetings community,

Please could someone point me in the right direction in terms of setting up SNMP on a DR4100. I downloaded the Administrators Guide and searched for SNMP in the doc, and it didnt give me what I wanted.

Is there another doc I must get this from? I checked the forums and came across an earlier post where the Dell admin had posted a link, but this was removed from the original post. 

I understand that SNMP queries need to be done via port 199, and when I nmap my DR4100 it shows this port is not open. 

Thanks
