Figure 6 shows the DB9 connector pin assignments for the serial port 1 and serial port 2 located on the rear panel of the SGI Origin 300 server and SGI Onyx 300 graphics system.
Figure 7 shows the DB9 connector pin assignments for the L1 console port on the SGI Origin 300 server and SGI Onyx 300 graphics system and for the console and modem ports located on the rear panel of the L2 controller.
 | Note: The pin assignments for the L1 console port, console port, and modem port are different from the pin assignments for the serial port 1 and serial port 2 because Pin 9 of the L1 console port, console port, and modem port is not connected. |
Figure 8 shows the pin assignments for the RJ-45 connector located on the rear panel of the SGI Origin 300 server, SGI Onyx 300 graphics system, and L2 controller.
Figure 9 shows the external SCSI VHDCI connector pin locations for the external SCSI connector located on the rear panel of the SGI Origin 300 server and SGI Onyx 300 graphics system. These pin locations are also used for the two SCSI connectors located on the rear panel of the TP900 storage module. Table 4 lists the pin assignments for these SCSI ports.
