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.
