Troubleshooting and Problem Solving
4.1 Overview
The Galaxy 55 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 Operator Panel in the rear of the enclosure.
The sensors for power, cooling and thermal conditions are housed within the Power Supply/Cooling modules. There
is independent monitoring for each unit.
If a fault is indicated on the Operator Panel (Ops Panel), please refer firstly to Table 4–1 and then to the section
referenced within that table.
4.1.1 Initial Start-up Problems

• plugs are incorrect
• cords are too short
Call your supplier for a replacement.
