Abstract
A power-using device for drawing power over a communication and power bus is provided. The power-using device is adapted to draw only power from the communication and power bus, the bus being connected to a power supply and host computer. The power-using device is further capable of communicating with the bus via a host bus adapter through a communication link not comprised by the bus. The host bus adapter is capable of receiving power and communication from the bus.
Claims17
An expander arrangement comprising a converter device, an expander device, and a bus,
- the converter device adapted to convert communication received in a first protocol from the bus to a second protocol and adapted to transmit the communication in the second protocol to the expander device over a pathway different from the bus, the expander device capable of providing power to an accessory device wherein at least a portion of communication to control the accessory device is provided by the converter device over the pathway, and
- the bus adapted to provide power to both the converter and expander devices.
An expander arrangement comprising a converter device, an expander device, and a bus,
- the converter device adapted to convert communication received in a first protocol from a bus to a second protocol and adapted to transmit the communication in the second protocol to the expander device over a pathway different from the bus, wherein the expander device is capable of receiving power from a second source, and
- the bus adapted to provide power to both the converter and expander devices.
An expander arrangement comprising a converter device, an expander device, and a bus,
- the converter device adapted to convert communication received in a first protocol from a bus to a second protocol and adapted to transmit the communication in the second protocol to the expander device over a pathway different from the bus, wherein the expander device is capable of providing power to an accessory device wherein at least a portion of communication to control the accessory device is provided by the converter device over the pathway, and
- the bus adapted to provide power to both the converter and expander devices.
An expander arrangement comprising a converter device, a first and a second expander device, and a bus,
- the converter device adapted to convert communication received in a first protocol from a bus to a second protocol and adapted to transmit the communication in the second protocol to the first expander device over a pathway different from the bus, and the bus adapted to provide power to both the converter and expander devices;
- the second expander device adapted to receive the communication in the second protocol from the converter device over a second pathway different from the bus wherein the second expander device is only capable of receiving power from the bus.
An expander arrangement comprising a converter device, a first and a second expander device, and a bus,
- the converter device adapted to convert communication received in a first protocol from a bus to a second protocol and adapted to transmit the communication in the second protocol to the first expander device over a pathway different from the bus, and the bus adapted to provide power to both the converter and expander devices;
- the second expander device adapted to receive the communication in the second protocol from the expander device over a second pathway different from the bus and wherein the second expander device is only capable of receiving power from the bus.
