These should be the OIDs for primary and redundant PSs..1.3.6.1.4.1.674.10895.5000.2.6132.1.1.43.1.7.1.2.1.3.6.1.4.1.674.10895.5000.2.6132.1.1.43.1.7.1.3 Hope this helps!  
Hi All - We are trying to monitor the redundant power supply status on one of our client's switches (mostly PC6248s and N3048s). I've looked through a lot of Dell's documentation, focusing on the 6248 and the Dell OpenManage Administrator documentation.  I can't find anything specific to the 6248 that spoke to SNMP OIDs for Redundant Power Supply status, though I did find OIDs in the OpenManage Administrator guide for it. However when I tried to do an SNMP walk on the switch for that OID I either got nothing or... WARNING: SNMP Walk issue: Exception calling "Walk" with "7" argument(s): "Exception of type 'Lextm.SharpSnmpLib.Messaging.TimeoutException' was thrown." So I am looking to see if anyone has had experience with this and could help me out.When I reached out to our technical rep they were given a CLI command to send me for this but the network monitoring tool we use needs an OID to monitor SNMP.   Thanks!
