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.
Blade Status LEDs 13
This section covers status LEDs for:
• Library control blade (LCB)
• FC I/O blade
• FC I/O fan blade
Figure 41 shows the location of the blade LEDs. Use Table 10 to interpret
the current status of the LEDs.
