If the NetBackup 5220 is powered on, the chassis cover should not be
removed for more than 5 minutes. Leaving the chassis open for a longer
time may result in decreased air flow and increased component
temperatures.

Cause 2: The fan module or the connection cables are not properly
connected
Cause 3: The cable connecting the mainboard and the power conversion

future release of this document.
