The supply voltages are +5 V, 3.3 V and +!2 V. The -12 V are required only if
needed on the PMC slot. If this voltage appears too late in the startup cycle, the

-12 V on
startup. In that case the -12 V inrush current to load the decoupling capacitors
on the CR! I and on the PMC may be detected as au overcurreut. T11is may
trigger the over current protection circuit and the Hot Swap controller shuts off
the complete voltage supply, which is indicated by the b

Make sure
that the -12 V power supply is active and up as fast or earlier as the other
voltages to prevent the shutdown due to over current situation

All output voltages of the CR! I boards have an over current protection
