En suivant les instructions au début de "IDRAC7 reference guide":

"_SSH or Telnet — Also referred as Firmware RACADM. Firmware RACADM is accessible by logging in to iDRAC7

using SSH or Telnet. You do not have to specify the iDRAC7 IP, user name, or password to run Firmware

RACADM commands. Similar to Local RACADM, after you enter the RACADM prompt, directly run the

commands without the RACADM prefix._"
