Cause 1: Alarm caused by environmental abnormality
1.
For alarms caused by environment abnormalities in the equipment
room, such as over-/low-temperature and over-/low-current,
examine the environmental conditions in the equipment room and
adjust them as necessary.
2.
Verify that the equipment room meets temperature specifications for
the NetBackup 5220 and Symantec Storage Shelf.

Make sure the front and back of the NetBackup 5220 are clear of any
obstructions so that air can flow easily from front to back.
