9 Dell EMC | Using USB NIC to Manage OEM Appliances
 WSMan can also be used for the firmware updates.
 Redfish can be used for iDRAC and BIOS attributes management. It currently does not support
repository-based updates.
Install non-DUP format software when system does not have physical network connectivity:
 When system has no physical iDRAC network connectivity, use USB NIC feature to install or update
software that is not in DUP format and cannot be run directly on the host OS. For example, when the
installer is in .pm, d7, or d9 file format.
 Use the web interface, SSH, or RACADM to install the software.
Example: racadm –r 169.254.0.1 –u <username> -p <password> update –f
<filepath><filename>.pm
Configuration, monitoring, and troubleshooting
 Modify BIOS and iDRAC attributes by sending request through USB NIC interface.
 Modify attributes from multiple interfaces on the host OS such as web interface, SSH, WSMan,
RACADM, and Redfish.
 Use RACADM through SSH to eliminate the need of additional software on the host OS. RACADM
commands via SSH can be sent through a script, which eliminates manual interaction.
 By default, all servers have the same USB NIC IP. This enables you to use a single script to configure
attributes on multiple servers. Server logs can also be collected for monitoring and troubleshooting
using this Interface. Scripts may be used for collecting the logs periodically, which eliminate manual
interaction.
