Type A Module Installation - Xycom XVME-976 Manual

Type A Module Installation

The XVME-976 is configured to accept the installation of Xycom's Type A
module in the PC/104 site. Type A modules contain a front panel that is at-
tached to the circuit board. Additional equipment included for the connec-
tion of the two modules:
•
Six standoffs
•
Eight nylon screws (connects the corners of the module to the XVME-976)
Installing the Type A Module onto the XVME-976 Adapter
Module
This procedure assumes the XVME-976 is attached to either the
XVME-654 or XVME-655 module. Procedures for installing
the XVME-976 onto those modules can be found earlier in this
chapter.
1. Follow procedures for the prevention of static discharge to prevent dam-
age to the circuitry of the modules.
2. Disconnect all power sources.
3. Loosen the screws on the front panel of the XVME processor module.
4. Remove the XVME-976 and any attached modules from the VME back-
plane, as follows:
5. Place the XVME-976 (and any attached boards) on a static-free surface
with the XVME-976 on top. See Figure 1-3.
6. Remove four screws securing the blank front panel assembly from the
XVME-976 (set aside for later).
7. Remove the blank front panel assembly from XVME-976 (save for pos-
sible future use).
8. Remove the four screws securing the mylar shield. Be sure to retain the
screws for use in securing the PC/104 module to the XVME-976.
9. Remove the mylar shield from the XVME-976 PC/104 site (save for fu-
ture use).
10. Install the new mylar shield that came with the Type A expansion board.
11. Insert two screws on the standoffs, adjacent to the PC/104 connector, to
secure the mylar shield.
12. Fold the mylar shield up to allow expansion module installation.
