Figure 118: Fan Module-Alarm LED (lower right corner)

NOTICE: The fan operates at full capability for at least seven days after the fan alarm first

occurs, allowing normal operation without requiring an immediate service call.

10.1.5

Power Supply LEDs

The power supply has three LEDs visible from the front panel. To interpret its condition, observe the

color of all the power supply LEDs. For example:

•

If the Alarm and Fan LEDs are red and the Status LED is green, the condition is "Lamp Test"

• If the Alarm LED is red and the Fan and Status LEDs are not lit, the condition is "Power Supply

Failure"
