Light path diagnostics is a system
of LEDs on the control panel and on the system board of the blade
server. When an error occurs, LEDs are lit throughout the blade server.
If the control panel indicates an error, use the descriptions of the
LEDs to diagnose the problem and take corrective action.
LEDs are available for the following components:
- Battery (base unit only)
- SAS disk drive on both the base unit and the expansion unit
- SSD on both the base unit and the expansion unit
- SSD carrier on both the base unit and the expansion unit
- Management card on the base unit only
- Memory modules (DIMMs) on both the base unit and the expansion
unit
- CFFh expansion card option on both the base unit and the expansion
unit
- CIOv form-factor expansion card option on both the base unit and
the expansion unit
- System board and chassis assembly on both the base unit and the
expansion unit
- A "check card below" LED on the expansion unit only
