Just to get you going you can download the manual from the link below. Download the DSS manual all iSCSI information is on this manual with NAS info. Just disregard the NAS information. Concerning the beeps we don't issue sound identifications in our software so this is mostly related or possibly in the BIOS setup. Are the beeps happening when you issue a command in the Console or Web GUI?
Beeps are somewhat random - but seem to happen more often when I am doing something from the console, browser - or as an example I just formatted a target and started to copy a large folder over to it. It randomly beeped at first seemed to have stopped and then you get a random beep or two every so often. I turned off the speaker in bios, so it shouldn't be coming from the motherboard......
