Some of you may want to configure the iDRAC and other system components through the system serial interface. This blog explains how to do just that ...
With the iDRAC7 firmware version 1.30.30 or later and BIOS 1.4.x or later installed, you can accomplish full deployment of your server through the serial interface (DB9 connector) on the server. Before you start please make sure External Serial Connector in BIOS is set to Serial Device 2. You can do this by going into F2 -> System BIOS -> Serial Communication -> External Serial Connector and set it to Serial Device 2. Here are the steps to configure through serial interface :
At this time, you can log in to the iDRAC as an administrator. To avoid having to log in each time and to prevent the log-in session from timing out, you may want to disable authentication. To do this, enter the following command:
racadm config -g cfgserial -o cfgserialconsolenoauth 1
To re-enable authentication, enter the same command, replacing the trailing “1” with a “0”.
Once logged in, you may configure BIOS, iDRAC, NIC and other settings. This configuration can be done from the serial interface by using RACADM commands. For complete information on RACADM commands, see the RACADM Command Line Reference Guide here.
Here are a few sample commands to get you started:
BIOS configuration / status:
racadm get BIOS
racadm set bios.satasettings.SataPortB off
racadm set BIOS.SysSecurity.SysPassword "dell"
iDRAC configuration / status:
racadm getconfig -g cfgSerial
racadm serveraction powercycle
NIC configuration / status:
racadm config -g cfgLanNetworking -o cfgNicEnable 1 [or 0]
racadm config -g cfgLanNetworking -o cfgNicIPv4Enable 1 [or 0]
racadm config -g cfgLanNetworking -o cfgNicUseDhcp 0 [or 1]
You might also want to update the firmware for BIOS, NIC, iDRAC, and / or the Power Edge Raid Controller (PERC) through the serial interface.
Here is a sample command to update the iDRAC7 firmware from a TFTP server:
racadm fwupdate –g –u –a [TFTP IP Address]
When you’re done making the desired configuration changes, power-up the server and the configuration changes and firmware updates will be applied by the Lifecycle Controller. If the server is already on, you’ll need to reboot to apply the settings.
Stay Tuned: PERC configuration will be supported in a future iDRAC firmware release.

just tried this out of the box with a new R720 running iDRAC firmware 1.30.30 and it does not work
Thanks for reaching out. It is possible that your External Serial Connector on the BIOS is not set to Serial Device 2 . We have edited the blog to include this step. Please let us know if this worked for you.
