Enclosure
Overheat
Overheating is a potentially serious condition because the
excessively high temperatures can lead to disk drive failure and
controller malfunction.
Overheating usually results from:
• Fan failure
• Poor air circulation around the enclosure
Fan Failure
On VessRAID, there are two kinds of fans:
• Power supply fan
• RAID controller fan
If a power supply fan fails, you must replace the power supply.
If a RAID Controller fan fails, you can replace it onsite. See
page 321.
Air Circulation
Air circulation around the VessRAID subsystem might be a more
complex problem. Use the thermometer icons to help you locate
the specific hot spot. Check for these conditions:
• Accumulated dust or objects blocking the fans
• Less than a minimum of 5 inches (13 cm) space between the
back of the VessRAID and the wall or other object
• Ambient temperature above 95°F (35°C) where the
VessRAID is operating
Cooling Down the Enclosure
To cool down a VessRAID enclosure:
• Correct any problems identified above
• Power down the VessRAID and let it sit for an hour or longer
