Table 2. Interfaces and protocols to access iDRAC Interface or Protocol iDRAC Settings Utility iDRAC web Interface RACADM Server LCD Panel/ Chassis LCD Panel Description Use the iDRAC Settings utility to perform pre-OS operations. It has a subset of the features that are available in iDRAC web interface along with other features. To access iDRAC Settings utility, press during boot and then click iDRAC Settings on the System Setup Main Menu page. 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. 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. 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. CMC web Interface Lifecycle Controller Telnet To reset iDRAC without rebooting the server, press and hold the System Identification button seconds. for 16 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 Use Lifecycle Controller to perform iDRAC configurations. To access Lifecycle Controller, press 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. 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. 24 Overview
