in a 4507 switch, I have 2 units of 4200W working in redundant mode. Each PSU has 2 input of 220V. Call it PSU 1-1, PSU 1-2 for PSU1 and PSU 2-1, PSU 2-2 for PSU 2.
When PSU 2-1 input is faulty (power source and cables are fine, confirm is PSU hardware faulty), the "show power" command indidated that the switch detected different power supplies installed and put the entire PSU 1 in err-disabled more. Causing the PSU to take the load with a total of 2100W available power. The load is around 900W. My question is, why is the switch not using PSU 1 as both the PSU 1-1 and 1-2 source are ok, and it can supply 4200W. Thanks in advance.
