Using the AUX Port and Module System Controller Commands

Attaching a Terminal or Modem to the AUX Port
To attach a terminal or modem to the AUX port, you need a serial cable with a DIN-8
connector at one end (for the AUX port) and an appropriate connector for the terminal
or modem (typically a DB25 connector) at the other end. Silicon Graphics has DIN-8 to
DB25 terminal and modem cables, and these are listed in Appendix B, “Cable
Descriptions.” You can also use the descriptions provided in that appendix to construct
your own cables. Note that the cables are the same as the ones used for Silicon Graphics
Indy, Indigo, and Indigo
2
workstations, and the CHALLENGE S server.
Follow these steps to attach the cable:
1. Plug the DIN-8 connector into the AUX port at the back of the system. See
Figure 4-7 for the location of the AUX port.
2. Attach the other end of the cable to your input device, for example a terminal,
modem, or other computer.
3. Use the following settings with your terminal (or modem or other input device):
• 9600 baud
• 8 data bits
• 1 stop bit
• no parity
• None, or XON/XOFF flow control
4. Test the connection by typing
Ctrl+t
and pressing
Enter
. You should see the
module system controller prompt:
MSC>
If you do not see any response, check your cable and communications settings for
your input device (terminal, modem, and so on). If this is a two-module system, be
sure to plug the cable into the AUX port of the master module. Be sure there is
power to the module system controller; the master power switch at the rear of the
system should be on. (See Figure 4-2.)
Once you are able to see the MSC prompt, you are ready to use the module system
controller.
The first task you should perform with the MSC is to reset the MSC password. See the
next section, “Using the Module System Controller.”
