Table 4 Fibre Port Link LED on FC I/O Blade
LED
Color Represents Fibre Port Link Status
Green Link and
activity
• Off – no link or link with constant activity*
• Solid On – link or blade is booting
• Flashing – link with activity
* LED flashing increases as the activity increases and can actually appear off if the activity is high enough. Also, when
the blade boots up, the link LEDs are all on until firmware initializes the ports, at which time they turn off until the
port transmitter is enabled and link is acquired.
FC I/O Fan Blade LED
RAS tickets typically report problems related to fan blades. Use Table 5 to interpret fan blade activity.

Amber Health of
the fan
blade
• Solid off — The fan blade is operating normally.
• Solid on — There may be one or more problems, including: fan speed is too high or too low;
temperature is too high; there is a faulty fan speed sensor; or there is a power control problem.
Tape Drive LEDs
RAS tickets typically report all problems related to tape drives, including error codes and TapeAlerts. By observing the blinking
pattern of LEDs on tape drives, however, you can discern which operation the tape drive is currently performing.
Figure 1 shows where the tape drive LEDs and the fibre port link LED are located.
