Hi to everyone. I bought a Dell m1000e with 3 psu and 7 blades, few switches on back, no MCM no kvi, 1 cables, i can start it up to test it ? i just have only one cable for one psu trugh my socket for 220v.

i try to start it, and the power supply has green light but on smal display from chassis say "cmc not present" whay should i do ?
