Appendix B Serial Over LAN
Hardware Setup
You can use an external serial port connector and null modem cable to setup the
MegaRAC® G4 to perform Serial over LAN operations. To do this, you must have an
external 9-pin serial port connector and cable plugged into the MegaRAC® G4 card’s
serial port connector at J10. Once the external 9-pin serial port connector is installed and
secured to the chassis, attach the null modem cable.
BIOS
After you have established a physical connection from your host system’s serial port to
you MegaRAC® G4 card, you must enable
Remote Access in your AMIBIOS.
Step Description
1 From the host system’s terminal, enter the AMIBIOS setup.
2 Confirm that your Onboard Serial Port you are using is enabled.
3 Enter the Remote Access Configurations menu.
4 Set the Remote Access setting to [Serial] .
5 Set the Serial Port Number to [COM1] or [COM2] depending on the serial
(COM) port you are using.
6 Set the Serial Port Mode baud rate you desire. By default, it is set to [19200
8,n,1].
7 If available, you can set the Post-Boot Support option. When enabled, the
MegaRAC® G4 attempts to output the DOS screens or the initial windows text
screens. This is really handy when you want to see the
OS Boot Menu .
8 Save and Exit the BIOS.
Connecting using Hyper Terminal
The best way to telnet into the MegaRAC® card is through Hyper Terminal. It is
assumed that you know how to use Hyper Terminal. Usage of Hyper Terminal is
therefore not documented here.
