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.
Symptoms
Control panel readout indicates fan problems
Device management screens indicate fan problems.
Possible Causes
Cause 1: The power is not turned on
Cause 2: The fan module or the connection cables are not properly
connected
Cause 3: The cable connecting the mainboard and the power conversion
board is not properly connected
Cause 4: The fan(s) are faulty
Fault Diagnosis
A flow chart to help diagnose red fan on/alarm indications is planned for a
future release of this document.
Procedure
Cause 1: The power is not turned on
Fans are powered by the NetBackup 5220 power. Therefore, if the main power
is off, the fan on/alarm indicator is red.
