Abstract
In one embodiment, an apparatus includes a power adapter configured for direct connection to a Power Supply Unit (PSU) installed in a network device, the power adapter comprising a power input port for receiving power on an Ethernet cable, a power converter module for converting the power received at the power input port to a PSU input power, and a power output connector for connection with a PSU power input connector.
Claims24
An apparatus comprising:
- a power adapter configured for direct connection to a Power Supply Unit (PSU) installed in a network device, the power adapter comprising:
- a power input port for receiving power on an Ethernet cable;
- a power converter module for converting the power received at the power input port to a PSU input power;
- a power output connector for connection with a PSU power input connector;
- and
- a fan for providing air flow to a fan inlet at the PSU.

An apparatus comprising:
- a Power Supply Unit (PSU) comprising a power input connector operable to receive a PSU input power and power network device components when installed in a network device, wherein the PSU is configured to verify that the PSU input power comprises a specific frequency and waveshape signature;
- and
- a power adapter coupled to the PSU and comprising a power input port for receiving power on an Ethernet cable, a power converter module for converting the power received at the power input port to the PSU input power, and a power output connector connected to the power input connector of the PSU.
A network device comprising:
- a Power Supply Unit (PSU) comprising a power input connector operable to receive a PSU input power and power one or more components of the network device;
- a fan for providing air flow to a fan inlet at the PSU;
- and
- a power adapter coupled to the PSU and comprising a power input port for receiving DC (Direct Current) pulse power, a power converter module for converting the DC pulse power to the PSU input power, and a power output connector connected to the power input connector of the PSU,
- wherein the PSU and power adapter are permanently coupled to define a power module configured for insertion into the network device and wherein the power output connector of the power adapter and the power input connector of the PSU define an internal connection at the power module.
