Using the serial port
The server serial port provides basic serial port functionality and serves as an interface to LO100. You
can configure the system serial port for exclusive use with LO100.
CAUTION: After enabling the serial port for use with LO100, legacy serial devices might not
function correctly if attached to the serial port.
You must configure the LO100 serial port hardware parameters to work with your respective serial port
communications software. LO100 serial port configuration is controlled through the BIOS Setup Utility.
Enabling serial access to the LO100
1. Power on the server by pressing the Power On/Off button on the front panel.
2. When POST displays the message, ROM-Based Setup, press the F10 key. If the server has an
administrator password configured, the system prompts you to enter the password. If the server does
not have a password configured, the main screen of the BIOS Setup Utility appears.
