Attaching Serial Cables; Attaching Serial (Ascii) Terminals - Silicon Graphics Origin200 Owner's Manual

Attaching Serial Cables

The serial port connectors are D-shell, 9-pin, male. Use a a cable with a DB9 female
connector to attach serial devices to the Origin200 server. The Origin200 serial port
connectors provide threaded hex-nuts so that you can fasten the cable connector to the
port.

Attaching Serial (ASCII) Terminals

You can connect an optional ASCII terminal to your Origin200 by using the serial cable
shipped with your server. It has a DB9 connector on one end and a 25-pin serial connector
on the other. See Appendix B, "Cable Descriptions" for information on this cable.
Be sure to read the documentation that comes with the terminal. Always connect your
system console terminal to serial port 1. You can connect an additional terminal to ports
2, 3, and 4. Set the terminal with the following operational characteristics:
• 9600 baud
• 8 bits
• 1 stop bit
• no parity
Use the following steps to properly connect a terminal:
1. Attach the keyboard (if applicable) and power connectors to the terminal.
Caution: Before plugging the terminal into either a 110-VAC or 220-VAC outlet, be
sure that the electrical rating on the UL-CSA label is in either the 100–120 VAC or
200–240 VAC range, whichever applies.
2. Connect the end of the serial cable that has the 25-pin connector to the back of the
terminal. (Some terminals have more than this connector on the back; if this is the
case, choose the connector marked Modem or COMM. Consult your terminal's
documentation if you are not sure which connector to use.)
3. Attach the end of the serial cable that has the DB9 connector to either port 1 (if the
terminal will be the system console) or one of the other ports.
4. Power on the terminal.
5. Restart the system or continue with other peripheral connections as needed.
