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 225: LED and Alarm Conditions shows the LED and alarm conditions.

Fan Removal and Replacement
WARNING: You can remove the fan assembly while the system is running, but you must
replace the new assembly within 60 seconds to avoid a thermal overload.
1. Place the new fan assembly close to the G600.
2. Loosen the thumb screws on the fan assembly, and pull it straight out (unplug it) as shown
in Figure 64: Fan Removal. The power for the fan automatically disconnects when the
assembly is unplugged.
3. Plug in the new fan assembly. The power for the fan automatically connects when the fan
assembly is plugged in.
4. Tighten every thumb screw on the fan assembly.
