IBM Type 8677 Light Path Diagnostics table, Lit LED Cause Action BladeCenter system LED panel

Light Path Diagnostics table

The system-error LED on the system LED panel is lit when certain system errors occur. If the system-error LED on your BladeCenter unit is lit, use the following table to help determine the cause of the error and the action you should take.
