System ID and status LED indicator codes The system ID indicator is located on the control panel of your sled. Figure 2. System ID and status LED indicators Table 1. System ID and status LED indicator codes System ID indicator code Condition Off Indicates system is in the off state. Blinking amber or steady amber Indicates system fault or error condition. Steady blue Indicates normal operating state. Blinking blue Indicates system ID engaged. Blink rate is 1 Hz.
Drive indicator codes Each drive carrier has an activity LED indicator and a status LED indicator. The indicators provide information about the current status of the drive. The activity LED indicator indicates whether the drive is currently in use or not. The status LED indicator indicates the power condition of the drive. Figure 4. Drive indicators 1.
