Hi,
Thats exaclty what i was doing. i started filling the banks from 1a 1b
then after that 2a 2b. ( till this time things were working fine) then
i added 3a and 3b and machine started giving beeps ( 3 short) . i added
more 4a 4b to see if thats works but didnt succeed. I guess i need to
check the power supply. But all the 7 seven servers which i tested
shudnt be having the same porblem ?
Please suggest
Thanks Again
