CP3004-SA
Power ramping on the CP3004-SA provides the hot plug functionality on the power interface. The PCI
interface does not support hot swap functionality. No microswitch, no blue LED, and no signal pre-
charge are provided on the CP3004-SA.
The ENUM signal on the CP3004-SA allows for hot swapping of peripheral boards with hot swap capa-
bility when the CP3004-SA is installed in the system slot.
Note:
The CP3004-SA itself is not hot swappable when inserted in a system slot. When inserted
in a peripheral slot, the CP3004-SA is hot pluggable.
2.7.8.5 Power Ramping
On the CP3004-SA a special power controller is used to ramp up the onboard supply voltages. This is
done to avoid transients on the +3.3V and +5V power supplies from the system. When the power supply
is stable, the power controller generates an onboard reset to put the board into a defined state.
2.7.8.6 ENUM# Interrupt
If the board is operated in the system slot, the ENUM signal is an input.
