The Global Power, Global Summary Fault, and Global Locate LEDs are general
indicators for the entire DS5020 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.

Controller LEDs

This section describes the primary LEDs, controls, and connectors on the rear of
the storage subsystem controller.
Figure 69 on page 107, Figure 70 on page 107, and Figure 71 on page 108 show
the three different DS5020 controller configurations that are available. Figure 69 on
page 107 shows the base DS5020 storage subsystem, with two Fibre Channel host
ports. For more information about DS5020 controller options and other components,
see the "Parts listing" on page 166.
