Table 3. Interfaces and protocols to access iDRAC
Interface or Protocol Description
To access iDRAC Settings utility, press <F2> during boot and then click iDRAC Settings on the
System Setup Main Menu page.
iDRAC web Interface Use the iDRAC web interface to manage iDRAC and monitor the managed system. The browser
connects to the web server through the HTTPS port. Data streams are encrypted using 128-bit
SSL to provide privacy and integrity. Any connection to the HTTP port is redirected to HTTPS.
Administrators can upload their own SSL certificate through an SSL CSR generation process to
secure the web server. The default HTTP and HTTPS ports can be changed. The user access is
based on user privileges.
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 or telnet. 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.
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.
CMC web Interface
In addition to monitoring and managing the chassis, use the CMC web interface to:
● View the status of a managed system
● Update iDRAC firmware
● Configure iDRAC network settings
● Log in to iDRAC web interface
● Start, stop, or reset the managed system
● Update BIOS, PERC, and supported network adapters
Lifecycle Controller Use Lifecycle Controller to perform iDRAC configurations. To access Lifecycle Controller, press
<F10> during boot and go to System Setup > Advanced Hardware Configuration > iDRAC
Settings. For more information, see Lifecycle Controller User’s Guide available at dell.com/
idracmanuals.
Telnet Use Telnet to access iDRAC where you can run RACADM and SMCLP commands. For details about
RACADM, see iDRAC RACADM Command Line Interface Reference Guide available at dell.com/
idracmanuals. For details about SMCLP, see Using SMCLP.
NOTE: Telnet is not a secure protocol and is disabled by default. Telnet transmits all data,
including passwords in plain text. When transmitting sensitive information, use the SSH interface.
SSH Use SSH to run RACADM and SMCLP commands. It provides the same capabilities as the Telnet
console using an encrypted transport layer for higher security. The SSH service is enabled by default
on iDRAC. The SSH service can be disabled in iDRAC. iDRAC only supports SSH version 2 with the
RSA host key algorithm. A unique 1024-bit RSA host key is generated when you power-up iDRAC for
the first time.
