Firmware Update RN4220 from 6.6.1 -> 6.7.4
I have an RN4220 with an iSCSI LUN that we use as a backup destination for our network. It's fully populated with 4TB WD Enterprise drives. I've been nagged with the "Firmware update available 6.6.1 -> 6.7.4" screen for a while, and had an opportunity to take down the backup server so I could firmware update the RN4220. 45 minutes ago, I clicked the Update button on the web console. It downloaded, said it needed to do a reboot. Pings dropped off, and it's not come back online since that point in time. The power light is flashing green, no other disk activity is evident. Next step? Never had to troubleshoot this thing before...
