2.11.2.1 Installing SA-Adapters Directly on A14C
With 10-pin connectors, you can install SA-Adapters directly on the A14C, like a
mezzanine module, with the I/O connector at the front.
Note: Please note that you can install adapters on the A14C directly only if you
have a suitable version of A14C (without PMC slots)!
Perform the following steps to install an SA-Adapter:
;
Make sure that the adapter matches the standard dimensions for SA-Adapters.
(See also installation hints in the adapter’s user manual.)
;
Power down your system and remove the A14C from the system.
;
Remove the two front panel screws and the two screws on top of the mounting
bolts of the SA-Adapter.
;
Remove the blind connector from the front panel, if you need a slot that is cov-
ered: Loosen the two screws at the front of the panel.
;
The SA-Adapter is plugged on the A14C with the component sides of the PCBs
facing each other.
