CEM-4
The CEM-4 is not redundant. When the CEM-4 is removed from the shelf:
l External management stops working
l All fans increase to maximum speed
l Some non-critical internal management of modules stops working
l Due to airflow shortcut, the CEM-4 needs to be reinserted or replaced in less than one
minute
l Airflow shortcut will lead to overheating and eventually a power shutdown of the shelf
