AM-1600 Upgrade: Hardware Installation

Eagle 450 Upgrade Instructions, Rev. A00
5.
Reinstall the CPU mounting plate, which now has the AM-138 attached. First slide the connector
end of the AM-138 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.
6.
Attach the AM-138 to the back panel using the provided male/female standoffs at the UPS status
port and the parallel port.
7.
Use the slide latch assembly to mount the Ethernet connector to the rear panel.
8.
Tighten the five screws attaching the rear panel to the back of the chassis.
HOOKING UP THE AM-138
1.
Attach two 6-pin cables from the power supply at P3 and P4 on the AM-138.
2.
Attach the SCSI cable to the AM-138:
•
If you’re using the narrow SCSI bus, plug the existing SCSI cable into P7.
•
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.
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.
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
AM-314 in any slot for compatibility with your previous configuration. See Chapter 3 of the
Eagle 450 Installation and Technical Manual for more serial I/O configuration information.
5.
Put an AM-90 board into each of the two bottom rear panel I/O slots (see Figure 7-7). Attach the
cable from the board for ports 0-3 at P1 on the AM-138; attach the cable from ports 4-7 at P2.
To use DB-9 connectors for the eight standard serial ports, do not install the AM-90
cards; instead, use the same cables you used to connect the on-board ports on the AM-
137 to the back panel. If you choose this option, you’ll need four back panel slots,
instead of two, for the eight on-board ports.
