If you have forgotten the password, you can set a new password. Connect to the console of UCS 6100 series fabric interconnect. Reload the fabric interconnect and when it boots up hit ctrl+L or ctrl+shift+R to go to loader prompt then boot the kickstart image; if you have two fabric interconnects connected in HA then first reload the subordinate fabric interconnect and bring it in loader prompt and then reload the primary and bring it in loader prompt, after this load kickstart image on the primary.
Configure the admin password using the “admin-password” command by going to config terminal mode. Now load the system image on the fabric interconnect or if you have HA load system image on the primary fabric interconnect. The password is now set to the new password you have just configured; if you have HA then now you can load the kickstart and system images on the subordinate fabric interconnect.
