• Firmware RACADM — Allows you to log in to the CMC using Telnet, SSH, or a serial connection. With firmwareRACADM, you can the RACADM implementation that is part of the CMC firmware.You can use remote RACADM commands in scripts to configure multiple CMCs. You cannot run the scripts directly onthe CMC web interface, because CMC does not support it.For more information about RACADM, see theChassis Management Controller for PowerEdge VRTX RACADM CommandLine Reference Guide.For more information about configuring multiple CMCs, see Configuring Multiple CMCs Using RACADM.Logging in to CMC Using Public Key AuthenticationYou can log in to the CMC over SSH without typing a password. You can also send a single RACADM command as acommand line argument to the SSH application. The command line options behave similar to the remote RACADM,because the session ends after the command is completed.Before logging in to CMC over SSH, make sure that the public keys are uploaded. To use this feature, you must have anEnterprise License.For example:• Logging in: ssh service@ or ssh service@<IP_address>, where IP_address is the CMCIP address.• Sending RACADM commands: ssh service@ racadm getversion and sshservice@ racadm getselWhen you log in using the service account, if a passphrase was set up when creating the public or private key pair, youmay be prompted to enter that passphrase again. If the passphrase is used with the keys, client systems runningWindows and Linux provide methods to automates the method. On client systems running Windows, you can use thePageant application. It runs in the background and makes entering the passphrase transparent. For client systemsrunning Linux, you can use the ssh agent. For setting up and using either of these applications, see their productdocumentation.Multiple CMC SessionsA list of multiple CMC sessions that are possible by using the various interfaces is given here.Table 3.
