RMC-ENV (Power/Fan Sensors)
G600 only
The AC Power Supply (650A) for a G600 media gateway (Rack-Mounted Cabinet - RMC)
supports one alarm lead that indicates the state of both the power and fan. The cabinets use
variable-speed fans to reduce noise. The power unit contains thermal speed control. A 3-pin
connector on the variable-speed fan assembly accepts variable input power to control its fan
speed and power its alarm circuitry.
Table 320: LED and Alarm Conditions shows the LED and alarm conditions.
