From searching it appears that there are a good number of Dell PowerEdge R610 users here, so I figured I'd ask if anyone has encountered and resolved this error before I take any more action.
I shut down a (then-functioning) R610 and when I powered it back on, it refused to boot, displaying the message "E2010: Memory not detected. Inspect DIMMs" on the status display.
The only bit of Dell's advice I have followed so far is to disconnect and reconnect power, to no avail. As much as I'd like to open up the chassis and start re-seating DIMMs, I'm just a lowly undergrad research assistant (with an extra dollar an hour of pay for my role as "system administrator") and I need approval before doing that -- so if anyone with experience with this same issue can chime in, I would much appreciate it.
