278 Section 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
GAM reports failed fans along with elevated temperature. On
Galaxy3G, there are two kinds of fans:
• Power supply, 2 fans each
• Cooling units, 1 fan each
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 the Maintenance
chapter for instructions on replacing the fans.
Air circulation around the Galaxy3G 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 Galaxy3G and the wall or other object
• Ambient temperature above 95
˚F (35˚C) where the
Galaxy3G is operating
To cool down a Galaxy3G:
• Correct any problems identified above
• Power it down and let it sit for an hour or longer
