Just recently we began to experience an odd problem with our E250. The console keeps reporting that the Ethernet link is down. However, ifconfig verifies the interface (hme0) is configured correctly. We can ping the loopback address and the IP address of the local machine. However, we can't see any other local machines. The Ethernet cable and port both test good.
We opened up the server to make sure the hardware was all seated properly. Still we get the error that the link is down. I'm used to getting this when the network goes down or when you disconnect the Ethernet cable but not with other symptoms like this.
I've done some additional research and some things I've seen may point to a boot PROM setting. Is this worth pursuing? Anyone else see something like this?
