Dear Experts,

I have CPU 410-5FH redundant configuration system running in plant. We have two 9 slots rack having 1 Power supply (MLFB- 407-0KR02-0AA1) and 1 CPU (410-5HX08-0AB0) in each Rack named as Rack-0 and Rack-1.

Now in RACK-01 power supply (407-0KR02-0AA1) is failed. I have spare power supply with different MLFB (407-0KA02-0AA0). Datasheet of both power supply is exactly same. Can I replace my faulty power supply (407-0KR02-0AA1) with spare power supply (407-0KA02-0AA0).

Can I do this replacement without downloading hardware configuration. Also will this replacement will upset the plant or is there any possibility to get master CPU in STOP mode while CPU in Rack-1 gets synchronize after power supply recovery.

Please help me to get out from this situation.

Thank You...!

 Hi niksss,

If i'ts running plant, then it's critical situation.

If situation permits, just replace power supply. Don't modify HW configuration & test master-follower switch over.
