S8300 Console Access from Services Port

[philipmyers]

We are trying to get access to the Redhat Linux Console in Single user mode on the S8300. Our instructions say to do the following:

1. User serial cable/DB9 (aka null modem, or cross-connect C5 cable) connect from a laptop PC to the Avaya Services Port.

2. Configure serial port for 9600 bits per second, 8 data bits, no parity, 1 stop bit, hardware flow control, vt100 emulation, and telnet terminal id vt100.

3. If the configuration in step 2 doesn't work, user F1 to enter BIOS configuration on the server and set console redirect to 9600 baud.

We are unable to access the console mode, we would like to boot up on Redhat Linux Rescue DVD and use the DD command to backup the Hard Drive, so while installing
Patches, we can restore in case of problems.

Put a Avaya CM installation CD and reboot S8300. After server is rebooted it access services port using ethernet cable from your laptop. You see three option which is normally seen on installations and the third option is to enter rescue shell
