Interpreting LEDs
LEDs provide a visual indication about the status of certain library
components. LEDs can sometimes communicate that a problem exists
when RAS tickets cannot. For example, an LED can indicate a firmware
problem that prohibits the library from generating RAS tickets.
The following components of the library have LEDs:
• Library Control Blade (LCB)
• FC I/O Blade
• FC I/O Fan Blade
• Tape drives
• Power supplies
Some of these components may also include a fibre port link LED.

LCB and FC I/O blade LEDs indicate status by the rate at which they
blink. The color of the LED identifies the area of the component being
reported.
