PWR-C1-440WDC= Cisco power supply hot-plug

Cisco power supply hot-plug.It operates on DC input voltage, typically at a specific voltage level compatible with the supported Cisco Catalyst switch models. DC power supplies are often used in environments where DC power infrastructure is preferred or required for stability and reliability.The term “hot-pluggable” means that the power supply module can be inserted or removed from the switch chassis without powering down the switch. This feature allows for maintenance and replacement of power supplies without interrupting network operations.
