9. Re-attach the fan to the new rear panel using the four screws and nuts removed in step 3 above.
Make sure it is oriented to exhaust air out of the chassis, in the same orientation it was previously
installed.
10. Reinstall the rear panel connectors, removed in step 3, to the new rear panel. Figure 6-5 shows
the position of the standard I/O connectors.
11. Reinstall the CPU mounting plate, which now has the AM-138-10 and rear sub-panel attached.
First slide the connector end of the AM-138-10 into place in the rear panel. Then, move the other
end into the proper orientation and press down over the small locating bumps in the chassis
bottom. You may have to rock the chassis top slightly forward or back to lock the locating
bumps in place, with the mounting plate flush against the chassis bottom. Once the plate is
placed properly, install its two mounting screws.
12. Attach the AM-138-10 rear sub-panel to the back panel using three screws.
13. From the outside of the back panel, install the adhesive backed rectangular cover plate contained
in the upgrade kit over the 15-pin connector hole in the new rear sub-panel next to the Parallel 0
connector.
14. Install cover plates over any connector mounting holes that will not be used to mount connectors.
The appropriate filler plates should either be obtained from the old rear panel or be provided in
your upgrade kit.
HOOKING UP THE AM-138-10
1. Attach two 6-pin cables from the power supply at P3 and P4 on the AM-138-10.
2. Attach the SCSI cable to the AM-138-10:
•
If you’re using the narrow SCSI bus, plug the existing SCSI cable into P7. Install the
active SCSI terminator supplied in your upgrade kit into the SCSI external connector at the
rear panel. See Appendix A for further SCSI terminator details.
•
For the Wide SCSI-2 bus, detach and remove the narrow SCSI cable if you haven’t already
done so. Plug the new wide cable into J13. Route it to each SCSI device, and then to the
external cutout on the back panel. Use the wide SCSI-to-50-pin adapter (PRA-00259-50)
to mount the external 68-pin connector. Attach the connector to the adapter using the
provided standoffs. If you have narrow SCSI devices, you must use a 50-pin to 68-pin
adapter (PDB-00440-91) to attach each to the wide SCSI cable. Install the active SCSI
terminator supplied in your upgrade kit into the SCSI external connector at the rear panel.
See Appendix A for further SCSI terminator details.
3. Attach I/O cables to any serial I/O boards you’ll be installing. You must attach the cables to the
boards before installing the boards in the AM-138-10.
CAUTION: Take care when removing or adding any I/O SIMM board. Do not force the
board into or out of the SIMM connector. These connectors are fragile and may break if
not handled properly. Do not remove or attach an I/O cable while the I/O board is
plugged into the SIMM connector.
4. Install any serial I/O boards (AM-314, AM-318-00, -02 or -10) into the slots at J7, J8, and J9. If
you are mixing I/O boards, we generally recommend you begin with an 8-port AM-318-xx
boards in J7, and place any AM-314 boards in the last used slots. However, you can place the
