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 FC I/O blade faceplate, black
lines indicate how each link LED belongs to a port.
Figure 44 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.
No color • Solid off — the drive brick is varied off or the drive cannot detect light
through a fiber optic cable (equivalent to no fibre cable plugged in). If
the drive brick is varied off, the blue status LED will be solid on.

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.
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.
