3.1 SBC Module
The 0818D supports one PICMG compliant Single Board Computer
(SBC). The SBC is mounted through the front of the enclosure in
slot #1.
The SBC is held in place with two injector/ejector handles that
stabilize the board when they are engaged. It is also secured by two
captive screws located on the SBC module’s faceplate. See the
following SBC module Removal/Replacement instructions.
3.1.1 Removal of the SBC Board Module
1. Shut down the system and turn off the DC power via the switch
on the front of the chassis. Verify that the Power On light is
extinguished.
2. Loosen the two captive screws on the SBC module’s faceplate.
Note: When loosened, the screws should be pushed inward to
prevent obstructing the movement of the injector/ejector handles.
3. Completely retract the injector/ejector handles by pressing them
away from each other.
Note: Some force may be required.
4. Slide the SBC module out of the chassis.
3.1.2 Installation of the SBC Board Module
1. With the Injector/Ejector handles in their outward (open) position,
insert the SBC module on its card guides until the handle latches
begin to engage. Make sure the two guide pins mate properly
into the corresponding hole in the SBC card guides.
2. Fully seat the SBC module by engaging the injector/ejector
handles, pressing them to their full inward position.
Note: If a firm steady pressure on the handles does not readily
seat the board, verify proper board alignment, clear insertion
path and connector pin straightness.
3. Secure the SBC board module by tightening the two captive
screws.
