RMC Webserver 2.0: error 304 occured

The  above is the error message when you tried to connect to DRAC III Web UI on Poweredge 2650, the old DRAC isn’t very stable, it just crashed without any reason from time to time.

To reset it the method is quite simple, you need to install Dell OpenManage 5.5 on CentOS, then issue the following command and wait 30 seconds before login again.

Since the DRAC III Firmware Version 3.37 (Build 08.13) is quite old, I want to update it to the latest 3.38, A00 (the release note said it has fixed remote console bug, so worth the update), all you need is download the harddisk version and extra it firmimg.bm1 to your TFTP root, then login to DRAC again and select the Update tap, upload and the firmware and wait a few minute to complete the whole update.
