Enabling or disabling OS to iDRAC Pass-through
In servers that have Network Daughter Card (NDC) or embedded LAN On Motherboard (LOM) devices, you can enable the OS
to iDRAC Pass-through feature. This feature provides a high-speed bi-directional in-band communication between iDRAC and
the host operating system through a shared LOM, a dedicated NIC, or through the USB NIC. This feature is available for iDRAC
Enterprise license.
NOTE:
iDRAC Service Module (iSM) provides more features for managing iDRAC through the operating system. For more
information, see the iDRAC Service Module User's Guide available at https://www.dell.com/idracmanuals.
When enabled through dedicated NIC, you can launch the browser in the host operating system and then access the iDRAC
Web interface. The dedicated NIC for the blade servers is through the Chassis Management Controller.
Switching between dedicated NIC or shared LOM does not require a reboot or reset of the host operating system or iDRAC.
You can enable this channel using:
iDRAC web interface
RACADM or WSMan (post operating system environment)
iDRAC Settings utility (pre-operating system environment)
If the network configuration is changed through iDRAC Web interface, you must wait for at least 10 seconds before enabling OS
to iDRAC Pass-through.
