The command is ALLOWANYFAN=1 in ROMMON. I did not have to use set to add variable, but use it to view. I'm not sure if it's case sensitive. I used all upper case and alarm indicators went out on sup module. Here's some log outout. Notice the temp rising. (The chassis powered down sup module after approx. 5 minutes without these commands. Notice the logg buff output warnings).
