Chapter 1: Overview of the Origin200 System
Ethernet Port
External Interrupt Ports

Each Origin200 module contains a single RJ-45 connector for 10-Base-T or 100-Base-TX
Ethernet. The connector has two integral LEDs that provide basic status. Network speed
is automatically negotiated. For a description of the pin assignments of the Ethernet port,
see Appendix A, "Connector Pinout Assignments."
Note:
Category 5 wiring is required for proper 100-Base-TX operation.
The Origin200 server has two connectors for use with the external interrupt interface.
This interface allows separate systems to send and receive interrupts over a dedicated
wire for purposes of inter-system synchronization. Using this device, a user process may
generate outgoing interrupts to other systems, or receive interrupts from other machines
in a variety of ways.
The connectors are 1/8-inch (3.5 mm) stereo jacks: one jack to send interrupts and one
jack to receive interrupts. For more information on using the external interrupt interface
and specifics about the jacks, see the ei(7) reference page. The wiring and voltages of the
jacks are also described in Appendix A, "Connector Pinout Assignments."
