Exm Module Insertion; Vme Backplane Jumpers - RadiSys EPC - 6A Hardware Reference Manual

1. Make sure the ejector handles are in the normal non-eject position. (Push the top
handle down and the bottom handle up so that the handles are not tilted.)
2. Slide the EPC-6A module into the VME chassis, making sure the top and bottom
board edges are in the chassis' card guides. Use thumb pressure on the handles to mate
the module firmly with the VME backplane connector.
3. Tighten the two screws in the top and bottom of the front panel to ensure proper
connector mating and prevent loosening of the module via vibration.

EXM Module Insertion

You can optionally install one EXM through the front panel of the EPC-6A. To install an
EXM:
Make sure that power to your VME system is off. EXMs are not designed to be
inserted or removed from live systems.
When inserting an EXM, avoid touching the circuit board, and make sure the
environment is static-free.
1. Remove and save the blank face plate from the EXM slot in the EPC-6A face plate.
2. Slide the EXM into place in the card guides. Push firmly on the EXM front panel to
insert its rear connector.
3. Tighten the thumb screws on the EXM's face plate.
The EPC-6A can accept most EXM types excluding those that either require a disk BIOS
in the EPC or do not fit by form factor.
Once an EXM is installed, you must to run the BIOS setup program to describe how the
specific EXM should be dynamically configured upon power-up. This is described in 3,
Operation.

VME Backplane Jumpers

The VMEbus contains several daisy-chained control signals. Almost all VMEbus
backplanes contain jumpers for these control signals to allow systems to operate with
empty slots. Failing to install these jumpers properly is a common source of problems in
building a new VMEbus system.
There are five jumpers per VME slot, one for each of the four bus-grant arbitration levels
and one for the interrupt-acknowledge daisy chain. Depending on the backplane
manufacture, the jumpers may be on the rear pins of the J1 connector, or may be alongside
it on the front or rear side of the backplane.
For the slot that contains the EPC-6A, remove the jumpers. Leave the jumpers inserted for
all empty slots. For slots otherwise occupied, consult the documentation from the
manufacturers of the modules.
