Troubleshooting and Problem Solving
4.1 Overview
The SS-1200-FCAL 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 either in the front or 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.
4.2 LEDs
Green LEDs are always used for good or positive indication, flashing Green/Amber if non-critical conditions exist.
Amber LEDs indicate there is a critical fault present within the module.
The Operator Panel displays the aggregated status of all the modules. The Ops Panel LEDs are shown in Figure 4–
1 and the LED status conditions are listed in Table 4–1
.
