The Global Power, Global Summary Fault, and Global Locate LEDs are general indicators for the entire DS4700 Express Storage Subsystem (or configuration, in the case of the Global Summary Fault). The Global Summary Fault LED turns on if a fault condition is detected in any component in the storage subsystem configuration, including all attached storage expansion enclosures. The Global Power, Global Summary Fault, and Global Locate LEDs shine through the front bezel.

Attention: If the Global Summary Fault LED lights, refer to the DS4000 Storage Manager client software to determine the problem with the storage subsystem. Also, inspect the Needs Attention LEDs on the other components in the storage subsystem to help isolate the fault to a specific component.

Controller LEDs

This section describes the primary LEDs, controls, and connectors on the rear of the storage subsystem controller for all models.
