Extraction Process:
1. The peripheral board is installed.
2. The operator starts to extract the peripheral board.
3. The BD_SEL# pin disconnects. The hardware
connection layer turns on the blue LED if it hasn’t been
turned on by software.
4. Medium length CompactPCI pins disengage.
5. Long length CompactPCI pins disengage. Early power
goes away. The peripheral board is in an unstable state
while pins are first disconnecting. This duration can
potentially be infinite if the board is just marginally
connecting the longest pins.
6. Board logic ground is connected to chassis ground
through a bleed resistor.
7. The board front panel is connected to chassis ground
through a bleed resistor.
8. The board is extract from the ESD card guide.
9. The board is uninstalled.
If it is not necessary to support Hot Swap Capability, users could
disable the function in BIOS setting and release IRQ9 or IRQ3 for
other resource. Please refer to the cPCI-6760D BIOS manual for
operating instructions.
Note:
Normally, IRQ9 will be occupied by ACPI. Please
disable the ACPI function when enabling the ENUM#
function in BIOS setting to route ENUM# through IRQ9
for supporting PICMG 2.1 Hot Swap for peripheral
boards. If the hot swap drivers of the peripheral boards
use only “polling algorithm”, it may not use ENUM# to
inform the system board of the existence of peripheral
boards, then the user can enable ACPI and disable the
ENUM# function.
