State and Explanation
• Solid on — loop initialization protocol (LIP) has occurred.
• Blinks at irregular intervals — host command/data activity is
occurring.
• Solid on — the library has enabled the drive data bus; it can detect
light through a fiber optic cable.
• Blinks at regular intervals — the library has enabled the drive data
bus, but light is not detected through the fiber optic cable.
• Solid off — the library has not enabled the drive data bus or the drive
brick is varied off. If the drive brick is varied off, the blue status LED
will be solid on.
Note: A UDS-2 drive with no fiber optic cable plugged in is healthy if
the link LED is solid off. A UDS-3 drive with no fiber optic cable
plugged in is healthy if the LED is amber and blinking at regular
intervals, indicating that the library has enabled the drive data
bus, but no light is detected.
