+5 V supply via CR9 and fused with max 2 A at CTM12. Don’t exceed 1 A at this connector for normal operation.
A.1.12 Power IN/OUT Connectors P7700, P7701
In case of Hot Swap (insertion or extraction phase) of the CR9 the CTM12 provides
the possibility of switch-off the power to external storage devices. The v5 V
and +12 V between power-in P7700 and power-out P7701 controls a Hot Swap
controller via MOSFETs. The Hot Swap controller cut the voltage when the signal
VCCOFF# is low. VCCOFF is controlled by the Hot Swap at the CR9. In case of over-
current the controller switches off the voltages, too.
