Features
Thermal Overload Protection
A thermal shutdown circuit is included within the 9C206-1 power supply. This
circuit protects the power supply from overheating if a thermal overload occurs.
Automatic recovery takes place after the thermal overload condition is corrected.
Load Sharing
Each 9C206-1 power supply uses a current sharing scheme whereby if two power
supplies are used, under all load conditions, each supply provides 50% (± 5%) of
the required load on each output. This feature increases the life of each power
supply.
Universal AC Input
The 9C206-1 power supply accepts AC input voltage ranging from 100Ð250 volts
at 50/60 Hz. In addition, power factor correction circuitry is employed to limit
harmonic distortion of the ac mains.
Hot Swapping
9C206-1 power supplies can be installed or removed from the front of the chassis
while another power supply is operating without affecting network operation.
LANVIEW LEDs
Each 9C206-1 power supply has three LANVIEW LEDs: the PWR Status LED
indicates the status of the 9C206-1 power output and the Power Supply Level
Indicator LED indicates the percentage of the power supply load being used. The
Redundancy LED indicates the redundancy status for dual power supply
systems.
9C306 System Monitor
The 9C306 System Monitor, shown in Figure 1-3, provides out-of-band
management capabilities for the SmartSwitch 9000-6 Slot system. The System
Monitor is inserted into the SmartSwitch 9000-6 Slot chassis, in the slot marked
SM, in the right side of the module card cage.
