The Fibre Channel link LED for a drive sled is located on the rear of the
drive sled. Figure 24

Table 12 describes how to interpret the Fibre Channel link LED activity
that you might see on the rear of the UDS-2 drive sled.
page 100 on page 135 describes the Fibre Channel link LED activity on
the rear of the UDS-3 drive sled.
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.
• 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.
