5. EVA Troubleshooting [4] Model 5214 FC-AL Drive Enclosure Lab Aid EMU LED Display Status and Recommended Actions LED LEGEND: = Off = On = Flashing The EMU locate function is active. This display has precedence over all others. Fault conditions cannot be displayed when the locate function is active. The EMU IS operational. The drive enclosure power (+5 V DC and +12 V DC are correct). There are NO drive enclosure faults. The EMU IS operational. There is a drive enclosure fault. Check the alphanumeric display error code for detailed information about the problem. The EMU IS operational. This display may be present when power is initially applied to the drive enclosure. Should this display fail to clear within a few seconds, could indicate a disk drive +12 V DC power supply problem. Note: When the +5 V DC is not correct, all the LEDs are off. There is an EMU Fault. There is NO drive enclosure fault. There is a drive enclosure fault. Either +5 V DC is not correct, or both +5 V DC and +12 V DC are not correct. Other error conditions may exist.
