Board Insertion/Replacement Under Power; Power Ramping; Enum# Interrupt - Kontron CP3002 User Manual

CP3002
2.11.9.4

Board Insertion/Replacement under Power

The following features are implemented on the CP3002:

• Power ramping

• ENUM signal handling (hot swapping of peripheral boards)
Power ramping on the CP3002 provides the hot plug functionality on the power interface. The
PCI signal interface does not provide hot swap functionality. No microswitch, no blue LED and
no signal precharge are provided on the CP3002.
The ENUM signal on the CP3002 allows for hot swapping of peripheral boards with hot swap
capability when the CP3002 is installed in the system controller slot.
Note ...
The CP3002 itself is not hot swappable when inserted in a system controller slot.
When inserted in a peripheral slot, the CP3002 is hot pluggable.
2.11.9.5 Power Ramping
On the CP3002 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.
2.11.9.6

ENUM# Interrupt

If the board is operated in the system controller slot, the ENUM signal is an input.
