Information on the internal power supply For information on the power supply, refer to the device installation guide.

Setting the internal power supply You can use the Power EXEC command to set and manage the internal power supply of the device. The device does not support the powerless EXEC command.

(Optional) Displays the status of each device in the stack, or the internal power supply of the specified device. Depending on the device member number in the stack, the range is from 1 to 9.

Internal power supply configuration example The following example shows how to set slot A power off.

Device # Power supply 1 Slot A off Disabling power supply A turns off the power to the PoE device and the switch. Do you want to continue? (Yes / [No]): Yes Device # June 10 04: 52: 54.389:% PLATFORM_ENV - 6 - FRU_PS_OIR: FRU power supply 1 Power off 10 June 04: 52: 56.717:% PLATFORM_ENV - 1 - FAN_NOT_PRESENT: Is not working Current device number

Configurable or programmable power supply. The configurable power supply unit can support various power specifications and different amounts of power output by selecting the appropriate module housed in the common base unit. With a programmable power supply, the user can flexibly fine-tune the input and output specifications of any module. If the standard component does not provide the required output combination for the power supply design, then the traditional hierarchy is the complete custom component. This will provide the design team with the necessary specifications. Or other parameters specified by the customer

A power supply is an electrical device that supplies power to an electrical load. The main function of the power supply is to convert the current from the power supply to the correct voltage, current, frequency and supply power to the load. As a result, the power supply may be referred to as a power converter. Some power supplies are standalone standalone devices, while others are embedded in the load devices they feed. An example of the latter is the power supply for desktop computers and home appliances.
