If the system status LED is anything other than solid green, you must investigate.
Environmental or component issues such as the following can trigger a status
change:
■ An excessively hot or an excessively cold equipment room.
■ AC current too high.
■ AC current too low.
■ Current surge from the AC power source affects operation.
■ Open or damaged chassis cover can cause overheating.
■ Components drifting out of specifications.
To determine why the system status LED shows issues
1
Access the NetBackup Appliance Web Console and click Monitor > Hardware.
2
Review the alerts page. If CPU-related alerts are shown, do the following:
■ Turn off the unit immediately.
■ Contact Symantec Technical Support and arrange for a replacement unit.
■ Keep system intact until the new unit arrives.

If power supply module alerts are shown, check the power supply section. See
“Troubleshooting appliance power supply problems” on page 95.

If memory (DIMM) related alerts are shown, contact Symantec Technical
Support.

If Over temperature or current alerts are shown, go to the equipment room
where the unit is installed. Do the following:
■ Check the room for temperature abnormalities.
■ Make sure that other sources of heat do not heat the unit. Check equipment
that is installed on, under, or next to the unit.
■ Check the unit for loose or unplugged power cables.
■ Make sure that the air vents are not blocked (minimum 3 inches of
clearance). Check the front and back of the unit.
■ Check the unit exterior for damage.
