Weird. A few weeks ago I turned up to a site that wasn't working after a power cut. They had two S5200's configured in a stack as core switches. Both had lost their firmware and we could only access the BIOS on them. All attempts to install/upgrade the firmware was a bust. Both had to be RMA'd and two days later we installed the replacements and 1 of those had the same issue.
