P-Class Power Issue

[Garabedy]

I am currently having an issue with a P-Class enclosure with 1U power supply. I cannot get more than 2 to 3 blades to power on at the same time. I have looked in the power supply mananent everything says ok. I noticed that only power supply 1 and 4 are on and the others just blink never going on when I add additional blades. from what I have read I only need 4 active power supplies to power the whole enclosure. I have looked everywhere to try to see if there are any setting or adjustment with no luck. Anyone have any troubleshooting tips that may help solve this?
