Embodiment Construction

[0023] The technical scheme of the present invention will be described in detail below in conjunction with the drawings and specific embodiments:

[0024] The Ethernet switch equipment includes a port driver PHY chip, and the PHY chip includes a virtual cable test module and a pre-emphasis adjustment module. The present invention uses the functions of these two modules to correlate the cable length, pre-emphasis value, and output power to obtain the cable length The relationship with the output power, so that the system can adjust the output power according to the cable length value, effectively reducing the waste of power.

[0025] figure 1 It is a schematic diagram of the adjustment system of the port output power of the Ethernet switch of the present invention. The system includes a virtual cable test module, a pre-emphasis adjustment module, a cable length value and a pre-emphasis value relationship table module, in which:

[0026] The virtual cable test module is configured...

Abstract

The invention discloses an adjusting system of output power of ports on an Ethernet switch and a method thereof. The system comprises a virtual cable test module, a relation table module of cable length values and pre-emphasis multiple values and a pre-emphasis readjusting module, wherein the virtual cable test module is used for carrying out length measurement for inserted cables and sending the obtained cable length values by measurement to the relation table module of cable length values and pre-emphasis multiple values; the relation table module of cable length values and pre-emphasis multiple values is used for searching corresponding pre-emphasis multiple values in a relation table of cable length values and pre-emphasis multiple values according to the cable length values and sending the pre-emphasis multiple values to the pre-emphasis readjusting module; and the pre-emphasis readjusting module is used for carrying out adjusting and output to output power of ports according to the pre-emphasis multiple values. The invention overcomes the problems that the output power of the ports of the switch surpasses power needed actually so as to cause that the power is wasted and the electrical power consumption is increased.

Description

Technical field [0001] The present invention relates to the field of Ethernet, in particular to a system and method for adjusting the output power of an Ethernet switch port. Background technique [0002] With the development of information technology, the power consumption of computers and communication equipment has increased sharply. In 2007, the total power consumption of IT products in my country reached 30 to 50 billion kilowatt-hours, which is almost equivalent to the total power generation of the Three Gorges Power Station in one year. Most of it is consumed by network equipment, so reducing the power consumption of communication equipment is the technological development trend of communication equipment. [0003] The currently applied technology is that when cables of different lengths are inserted into the ports of an Ethernet switch, the output power of the ports is the same, because short cables do not require high output power from the ports like long cables, so if a...
