Hi, You may be able to use the console redirection, but the boot screen usually goes too quickly for the key press before it initializes the redirect. Here is the cable pinout for the console port.  [URL]
Is there a way to access the boot menu on a M8024 though the CMC console redirect? Bought a used switch and I am unable to log in and need to reset the password and all the settings. If not will any usb serial cable work or is there a specific one I need to use? Thanks!
