HOOKING UP THE AM-138-10

Attach two 6-pin cables from the power supply at P3 and P4 on the AM-138-10.

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.

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.

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 250 Installation and Technical Manual for more serial I/O configuration information.

If you purchased the optional AM-90 Lightning boards for the eight on-board serial I/O ports,

install them into each of the two bottom rear panel I/O slots (see Figure 6-4). Attach the cable

from the board for ports 0-3 at P1 on the AM-138-10; attach the cable from ports 4-7 at P2.

If you are using DB-9 connectors for the eight on-board serial ports, use the same cables you

used to connect the on-board ports on the AM-137 to the back panel. Use the dual DB-9

connector adapter plates to mount the DB-9 connectors to the back panel. If you choose this

option, you’ll need the bottom four back panel slots, instead of two, for the eight on-board ports.

Install cabling from any other serial I/O boards to the back panel, following the installation

instructions for the I/O board. If you’re using AM-90 cards for the back panel connections

(which we recommend), insert the bottom AM-90s first and work your way up the back panel.

Make sure pin-1 orientation is correct for all cable connections.

If you have a brace for the serial I/O boards (DWB-20791-00 or -01), install it following the

instructions in PDI-20791-00.
