Table 3. Interfaces and protocols to access iDRAC (continued)
Interface or Protocol Description
Server LCD Panel/
Chassis LCD Panel
Use the LCD on the server front panel to:
● View alerts, iDRAC IP or MAC address, user programmable strings.
● Set DHCP
● Configure iDRAC static IP settings.
For blade servers, the LCD is on the chassis front panel and is shared between all the blades.
To reset iDRAC without rebooting the server, press and hold the System Identification button
for
16 seconds.
NOTE: LCD panel is only available with rack or tower systems that support front bezel. For blade
servers, the LCD is on the chassis front panel and is shared between all the blades.
RACADM Use this command-line utility to perform iDRAC and server management. You can use RACADM
locally and remotely.
● Local RACADM command-line interface runs on the managed systems that have Server
Administrator installed. Local RACADM communicates with iDRAC through its in-band IPMI host
interface. Since it is installed on the local managed system, users are required to log in to the
operating system to run this utility. A user must have a full administrator privilege or be a root
user to use this utility.
● Remote RACADM is a client utility that runs on a management station. It uses the out-of-band
network interface to run RACADM commands on the managed system and uses the HTTPs
channel. The –r option runs the RACADM command over a network.
● Firmware RACADM is accessible by logging in to iDRAC using SSH. You can run the firmware
RACADM commands without specifying the iDRAC IP, user name, or password.
● You do not have to specify the iDRAC IP, user name, or password to run the firmware RACADM
commands. After you enter the RACADM prompt, you can directly run the commands without
the racadm prefix.
iDRAC RESTful API and
Redfish
The Redfish Scalable Platforms Management API is a standard defined by the Distributed
Management Task Force (DMTF). Redfish is a next-generation systems management interface
standard, which enables scalable, secure, and open server management. It is a new interface that
uses RESTful interface semantics to access data that is defined in model format to perform out-
of-band systems management. It is suitable for a wide range of servers ranging from stand-alone
servers to rack mount and bladed environments and for large scale cloud environments.
Redfish provides the following benefits over existing server management methods:
● Increased simplicity and usability
● High data security
● Programmable interface that can be easily scripted
● Follows widely-used standards

WSMan
The LC-Remote Service is based on the WSMan protocol to do one-to-many systems management
tasks. You must use WSMan client such as WinRM client (Windows) or the OpenWSMan client
(Linux) to use the LC-Remote Services functionality. You can also use Power Shell or Python to
script to the WSMan interface.
Web Services for Management (WSMan) is a Simple Object Access Protocol (SOAP)–based
protocol used for systems management. iDRAC uses WSMan to convey Distributed Management
Task Force (DMTF) Common Information Model (CIM)–based management information. The CIM
information defines the semantics and information types that can be modified in a managed system.
The data available through WSMan is provided by iDRAC instrumentation interface mapped to the
DMTF profiles and extension profiles.
