That doesn't mean you can't do it. Here are the instructions, ------------- CONFIGURING A RS-232 CONSOLE on a 712 An RS-232 console is not a supported feature in the 712 products. For this reason users cannot select the RS-232 port as a console from the BOOT_ADMIN prompt. These instructions will configure an RS-232 console with 9600 Baud, 8 data bits, 1 stop bit, and no parity. HOW-TO INSTRUCTIONS NOTE: If the following instructions are not entered correctly, your system may be left in an un-usable state. Contact support to "dagger" your system in this case. Power up the 712 system. Press (ESCAPE) during boot to abort auto booting the system. At the BOOT_ADMIN> prompt, use the boot command and the isl keyword. This will stop the boot sequence at ISL instead of booting to the OS. For example: 'boot scsi.6 isl' At the ISL> prompt, type 'conspath 2/0/4.0x283' At the ISL> prompt, type 'disp' and verify console path is: (hex) 2/0/4.283.0.0.0.0.0 If necessary re-type the conspath command above. Connect an RS-232 terminal to the system. Power cycle the system to bring it up on an RS-232 console. ------------- As it indicates above, *BE VERY CAREFUL* or you can hose your system. If you do, I have one of the "dagger" cards that can be loaned out to fix it. -- Matt Taggart taggart@fc.hp.com
