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.
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.

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.
