Hot Swap Considerations
The CPIP5430 is a CompactPCI form factor single board computer with
hot swap capabilities. This allows insertion or removal of the board from
a powered chassis without damage, with proper pin staging on the
backplane. It does not employ a PCI bridge and can therefore be installed
in a payload slot in an MXP3000 Series Platform chassis.
Insertion
The CPIP5430 supports live insertion. Live insertion makes on-board reset
logic cause a reset. The reset signal routes directly into the board reset
logic and ensures proper bootup.
✓
The chassis is powered up.
✓
The CPIP5430 is inserted into the MXP payload slot on the
backplane. The blue LED is illuminated. When fully seated the
ejector levers are closed, at which point the blue LED should go
off after a short delay due to the IPMI controller.
✓
The system starts to boot.
Extraction
Following are the stages of extraction for a CPIP5430:
✓
When the ejector lever is opened, the IPMI control circuitry is
signalled.
✓
The IPMI satellite controller communicates with the BMC and/or
the resident OS. If software exists to interpret the ejector open
event, it may communicate with the resident OS causing the board
to properly shut down. If software exists to monitor the shutdown,
it may also illuminate the blue LED to indicate that the board can
safely be removed.
Note
While the IPMI controller will extinguish the blue LED
when the ejector lever is closed upon insertion, it is the
responsibility of software to illuminate the blue LED
during extraction.
