Page 15Installation Instructions: AM-137 Board AM-1600/1400 Upgrade
4.Install the three phillips-head screws that secure the AM-137 board to the chassis
bottom. Use the same three screws you removed from your old CPU board.
5.Plug the two power supply connectors into the AM-137 board. Both connectors
plug into the AM-137 board exactly as they were plugged into your old CPU board.
6.Plug the 50-pin SCSI connector into the AM-137 board at location J9. Like the
power supply cables, the SCSI interface cable plugs into the AM-137 board
exactly as it plugged into your old CPU board.
7.Plug the front panel display cable into the AM-137 board at location J10. The
cable connector is keyed and will only plug in one way. If you are updating a
deskside chassis, discard the AM-968 front panel interface board.
8.For the desktop chassis, the wire harness extending from the display panel plugs
into J900 on the AM-137 board. The J900 connector is located in exactly the
same position as on your old CPU board board. The connector is keyed and will
only plug in one way.
For the deskside chassis, the wire pairs formerly plugged into the AM-968 front
panel interface board should be plugged into the AM-137 board as follows:
Function Wire Pair AM-137 Connection
RESET SW black/green W3
DISK Light red/white W12 (white wire down)*
RUN Light yellow/white W9 (white wire down)*
POWER Light green/white W8 (white wire down)*
* if lights do not function in this orientation, reverse the orientation.
9.If your configuration includes a floppy drive, you must install an AM-219 floppy
controller. The AM-219 is not part of the AM-137 upgrade kit; it must be ordered
separately. To install the AM-219 board, follow the instructions in the
AM-219
Diskette Controller Installation Instructions
.
10.Install the memory SIMM included with your upgrade order in connector J7 on the
AM-137 board. Special care must be taken when installing a SIMM module. The
figure below shows how the curve in the SIMM module must align with pin-1 on
the AM-137’s SIMM connector.
The SIMM must be inserted into the connector at a slight angle and after you feel
the module settle into the connector, you rotate the SIMM into an upright position,
as shown in the illustration. When the SIMM is properly positioned, the metal
retainer clips at each end of the connector will click into position, locking the SIMM
in place.
