Two more dead B5 PSUs

Just adding a datapoint to this general topic.

Within the last month I’ve replaced two Mimosa brand PSU’s for two B5’s at different sites. They seem to last about 2-3 years before either failing completely, or the Ethernet side stops working. The equipment is 2 and 4 years old respectively.

All the usual, grounded, UPS’s, all other equipment is rock solid.
