MD1200 Power Vault is in Fault State

Hello,

We have an MD1200 Power Vault, where the enclosure status LED is flashing amber indicating that it is in "fault state".  The device is out of warranty.  What can I do to resolve this issue short of buying a new one?  If buying a new one is the resolution, so be it, but I would like to attempt to resolve it in other ways first.  Any help is greatly appreciated.

Thank you.
