Tape Drive Fibre Port
Link LED 13
The fibre port link LED shows the current state of the FC link and
indicates whether or not the link is ready to transmit commands. The
fibre port link LED on a tape drive is located on the rear of the tape drive,
beside the fibre port.
Use
Table 14 to interpret FC link activity:

• Solid ON — Loop initialization protocol (LIP) has
occurred.
• Blinks at regular intervals — Host command/data
activity is occurring.
Amber Online and light detected • Solid ON — The library has enabled the tape drive data
bus, and it can detect light through a fibre optic cable.
No color No activity or no light

• Solid OFF — Either the tape drive is off or the tape drive
cannot detect light through a fibre optic cable (which is
equivalent to a missing fibre cable). If the tape drive is
offline, the tape drive’s blue status LED will be solidly
lit.
