3.9.8.4. Board Insertion/Replacement under Power
The following features are implemented on the CP3005-SA:
 Power ramping
 ENUM signal handling (hot swapping of peripheral boards)
Power ramping on the CP3005-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 precharge are provided on the
CP3005-SA.
The ENUM signal on the CP3005-SA allows for hot swapping of peripheral boards with hot swap capability when the
CP3005-SA is installed in the system slot.
The CP3005-SA itself is not hot swappable when inserted in a system slot. When inserted in
a peripheral slot, the CP3005-SA is hot pluggable.
3.9.8.5. Power Ramping
On the CP3005-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.
3.9.8.6. ENUM# Interrupt
If the board is operated in the system slot, the ENUM signal is an input.
