Communicating With iDRAC Through Serial
Connection Using DB9 Cable
You can use any of the following communication methods to perform systems management tasks through serial connection to
rack and tower servers:
RAC Serial
IPMI Serial Direct Connect Basic mode and Direct Connect Terminal mode
NOTE:
In case of blade servers, the serial connection is established through the chassis. For more information, see the
Chassis Management Controller Users Guide available at dell.com/support/manuals.
To establish the serial connection:
1. Configure the BIOS to enable serial connection:
2. Connect the Null Modem DB9 cable from the management stations serial port to the managed systems external serial
connector.
3. Make sure that the management stations terminal emulation software is configured for serial connection using any of the
following:
Linux Minicom in an Xterm
Hilgraeves HyperTerminal Private Edition (version 6.3)
Based on where the managed system is in its boot process, you can see either the POST screen or the operating system
screen. This is based on the configuration: SAC for Windows and Linux text mode screens for Linux.
4. Enable RAC serial or IPMI serial connections in iDRAC.
