Overheating
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
WebPAM PROe reports failed fans along with elevated
temperature. On VTrak, there are two kinds of fans:
• Power supply
• Cooling unit
If a power supply fan fails, you must replace the power supply. If
a cooling unit fan fails, you can remove the cooling unit and
replace only the fan itself.
No tools are required for either procedure. See “Replacing a
Power Supply” on page 259 and “Replacing a Cooling Unit Fan or
Blower” on page 260.
Air circulation around the VTrak enclosure may 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 VTrak and the wall or other object
• Ambient temperature above 95°F (35°C) where the VTrak is
operating
To cool down a VTrak:
• Correct any problems identified above
• Power it down and let it sit for an hour or longer
