8.1AM-137 Rear Panel I/O Adapter Plate Configuration
Unlike your old CPU board, the AM-137 board has either four or eight on-board serial
ports. Your AM-137 installation kit may have cables (DWB-10120-01) designed to
support the on-board serial ports, or you should use the cables from your existing
configuration if you are upgrading a deskside chassis. Each cable has four female DB9
connectors. One of the cables plugs into the AM-137 board at location J4; its four DB9
connectors attach to the rear panel using DB9 cutouts specified on the following page.
The other cable plugs into the AM-137 board at location J5; its four DB9 connectors
attach to the rear panel using the additional DB9 cutouts. A rear panel illustration for the
desktop chassis with the AM-137’s eight on-board serial ports installed is shown below:
