I wasn’t able to connect to an iDRAC on a Dell PowerEdge R710. It was plugged into an active switchport but just would not get link. With OpenManage Server Administrator installed on the server I looked at the Configuration tab in the Remote Access section.
I noticed that NIC Selection was set to Shared. That seemed odd so I compared that setting to another R710. The other one was set to Dedicated. I switched the problem one from Shared to Dedicated & it started working.
I noticed that one of my many brand new Dell PowerEdge R710 servers was generating an error during POST that said, “Warning: Unsupported memory configuration detected. The memory configuration is not optimal.”
Well that doesn’t look right. Looking in the BIOS under memory settings I see that Memory Operating Mode is set to Optimizer Mode.
Yeah…that’s not right. Shame on Dell for sending this out wrong. Let’s change that to Advanced ECC Mode.
Rebooted & no more error.
