Interfacing
Some general interfacing guidelines are presented below. Do not hesitate to contact the
factory if you need more assistance.
Installation
The PMC is mounted to the PCIBPMCX2 prior to installation within the chassis. For
best results: with the PCI bracket installed, install the PMC at an angle so that the PMC
front panel bezel penetrates the PCI bracket then rotate down to mate with the PMC
[PnX] connectors. The rear slot does not have the bezel interaction and can be
mounted directly.
There are four mounting locations per PMC. Two into the PMC mounting bezel, and
two for the standoffs near the PMC bus connectors.
Start-up
Make sure that the "system" can see your hardware before trying to access it. Many
BIOS will display the PCI devices found at boot up on a "splash screen" with the
VendorID and CardId for the PMC installed and an interrupt level. If the information is
not available from the BIOS then a third party PCI device cataloging tool will be helpful
Watch the system grounds. All electrically connected equipment should have a fail-
safe common ground that is large enough to handle all current loads without affecting
noise immunity. Power supplies and power consuming loads should all have their own
ground wires back to a common point.
Power all system power supplies from one switch. Connecting external voltage to
the PCIBPMCX2 when it is not powered can damage it, as well as the rest of the host
system. This problem may be avoided by turning all power supplies on and off at the
same time. This applies more to the PMCs installed onto the PCIBPMCX2 than the
PCIBPMCX2 itself, and it is smart system design when it can be achieved.
