Pmc - SMART Embedded Computing MVME7100ET Installation And Use Manual

Hardware Preparation and Installation

PMC

The PMC connectors are placed to support two single-width PMCs or one double-width
PMC. PMC site 1 supports front PMC I/O and rear PMC I/O via the Jn4 connector. PMC 1
I/O is routed to the VME P2 connector. PMC site 2 only supports front PMC I/O and does
not have a Jn4 connector. The PMC 1 Jn4 user I/O signals only support low-current high-
speed signals and thus do not support current-bearing power supply usage.
In most cases, the PMCs are already in place on the baseboard. The user-configured
switches are accessible with the PMCs installed. The on-board PMC sites are configured
to support +3.3V I/O PMC modules. The onboard PMC sites do not support +5.0V I/O PMC
modules.
Follow these steps to install a PMC onto the MVME7100ET board.
Installation Procedure
Read all notices and follow these steps to install a PMC on the baseboard.
Damage of Circuits
Electrostatic discharge and incorrect installation and removal can damage circuits
or shorten their life.
Before touching the board or electronic components, make sure that you are
working in an ESD-safe environment.
Product Damage
Inserting or removing modules with power applied may result in damage to module
components.
Before installing or removing additional devices or modules, read the
documentation that is provided with the product.
1. Attach an ESD strap to your wrist. Attach the other end of the ESD strap to the chassis
as a ground. The ESD strap must be secured to your wrist and to ground throughout
the procedure.
2. Remove the PCI filler from the front panel.
3. Slide the edge connector of the PMC module into the front panel opening from behind
and place the PMC module on top of the baseboard. The four connectors on the
underside of the PMC module should then connect smoothly with the corresponding
connectors on the MVME7100ET.
4. Insert the four short phillips-head screws (provided with the PMC) through the holes on
the bottom side of the MVME7100ET and the PMC front bezel and into rear standoffs.
Tighten the screws. Refer to
