• B - Select the power supply in slot B. Power supply socket B is closest to the outside edge of the switch

(Optional) Displays the internal power status of each switch or designated switch in the stack. The range is 1-9 depending on the switch member number in the stack.

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

Switch # Power supply 1 Turn off slot A If you disable power supply A, the PoE device and switch may turn off ... Do you want to continue? (Yes / [No]): Yes Switch # Jun. 10 04: 52: 54.389:% PLATFORM_ENV - 6 - FRU_PS_OIR: Power supply 1 of FRU has been turned off June 10 04: 52: 56.717: PLATFORM_ENV-1-FAN_NOT_PRESENT Now

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

Configurable power supplies allow the design team to respond to changes in marketing specifications instantly and avoid NRE and design costs associated with changing custom unit specifications and replacing standard parts. As a result, OEMs can benefit from sensitive design processes to their customers' needs and respond quickly to changes in customer demand. A configurable power supply protects OEM designers from this level of uncertainty and meets various power requirements with a single board layout and power footprint. Addressing different power requirements is a simple matter of replacing the modules in the fixed base unit.
