Chapter 8: Troubleshooting
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 reports failed fans along with elevated temperature. On VTrak, there are two kinds of fans:
•Power supply, 1 fan each, 2 fans total
•Cooling units, 2 fans each, 4 fans total
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 page 197 for instructions on replacing the fans.
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, do the following:
•Correct any problems identified above
•Power it down and let it sit for an hour or longer
