The Global Power, Global Summary Fault, and Global Locate LEDs are general
indicators for the entire DS4200 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:
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.
