Hello,
One of our customers has an R720 with a strange problem.
Initially (in Dec) it seemed to have a faulty system board as the iDRAC was not responding. Switch configs, iDRAC configs, cables were all ok. We dispatched a new system board and applied the license, and everything seemed fine.
Now the iDRAC is not responding again. It shows solid green LED's, and when we pull the cable, the solid green LED's stay lit. Any ideas?
