B Using the Serial Interface

This section describes specific configuration options available for the serial interface.

The Fibre Channel to SCSI router allows the user to access Ethernet configuration settings through the serial interface.

Serial Port Connection

The RJ-11 connector on the back panel of the Fibre Channel to SCSI router provides a serial port that is compatible with RS-232 signaling levels. The Fibre Channel to SCSI router is designed to communicate with a terminal or any operating system utilizing a terminal emulator. The baud rate, data bits, stop bits, parity, and flow control of both the router and the host system must use the same settings. The autobaud feature described in the next subsection provides an effective method to set the baud rate of the router and host system.

Autobaud Feature

The autobaud feature automatically configures the baud rate on the Fibre Channel to SCSI router. Once you set the baud rate in the terminal emulator, wait until the Fibre Channel to SCSI router completes the power-on self test (POST) and then the Firmware Initialization process. This can take up to 90 seconds, during which time the POST and initialization information might or might not be visible on the terminal or terminal emulator. After this process has completed, press the Enter key slowly 7 or 8 times (or type shift-z) and the Fibre Channel to SCSI router automatically detects the baud rate being used by the serial port. The baud rate is then saved in the Fibre Channel to SCSI router’s configuration and is retained through future power cycles.

Note. Pressing the Enter key before the POST has completed is of no benefit to the autobaud feature. Wait until both the POST and the Firmware Initialization processes have completed before pressing the Enter key. This might take up to 90 seconds.

The baud rate used by the terminal or terminal emulator must be 9600, 19200, 38400, 57600, or 115200 for the autobaud feature to recognize it. The Fibre Channel to SCSI router does not function properly at any other baud rate.
