Firmware issues with BL35P and power loss is it possible to repair blades post failure

[eddieitman]

At the organization I work for they never performed the firmware upgrades as per the advisory

We had a power loss and 13 of the 16 blades will now not power on, I have upgraded the firmware on all of the blades since, but the 13 blades will not power on, I need to know if there is a way to get these back up either via a console cable, or a visit from a HP engineer.

Or will we need to replace all of the blades.

Been there, done that.  System board replacement time, yay!
