The Galaxy 65 Enclosure includes a processor and associated monitoring and control logic to enable it to diagnose problems within the enclosure’s power, cooling and drive systems.

The Enclosure Services Processor is housed along with the Ops Panel in the rear of the enclosure.

The sensors for power and cooling conditions are housed within the Power Supply/Cooling modules. There is independent monitoring for each unit.

If a fault is indicated on the Ops Panel, please refer firstly to Table 7–2and then to the section referenced within that table.
