The system power consumption of a switch is determined by its SRPUs, LPUs, and fan tray. Specifically, 

the system power consumption of a switch is equal to the power consumption of its SRPUs, LPUs, and 

fan tray put together. 

For how to install power modules and power module adapters, refer to section 5.2  "Removing and 

Installing a Power Module."

Y means that the power module fits the chassis. 

z 

N means that the power module cannot be used in the chassis.

As shown in the figure, above the power switch is the power LED. If the power LED is green, the power 

supply operates normally. If the LED is red, the power supply is abnormal.
