CABINET (Cabinet Sensors)
The Compact Modular Cabinet (CMC) AC Power Supply (650A) supports one
alarm lead that indicates the state of both the power and fan. With multiple
cabinets, alarm leads from each cabinet are tied into a single lead. The CMC
uses variable speed fans to reduce noise. The CMC power unit contains Thermal
Speed Control and an alarm circuit. A variable speed fan has a 3-pin connector
for the variable input power for speed control and its alarm circuitry.
Table 3-139
shows the LED and alarm conditions.
