Drive Sled Link LED States
(UDS-3)
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.
FC I/O Blade Fibre Port Link LED
The link LED for an FC I/O blade fibre port is located next to the port. On
the I/O blade faceplate, black lines indicate how each link LED belongs
to a port.
Figure 26 shows the locations of the I/O blade Fibre port link
LEDs.
LED Color Represents State and Explanation
Green LIP and
activity
• Solid on — loop initialization protocol (LIP) has occurred.
• Blinks at irregular intervals — host command/data activity is
occurring.
Amber Online and
light
detected
• 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.
No color • 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.
