Embodiment Construction

[0019] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] figure 1 A block diagram of a device for automatically adjusting the power level of a QSFP+ optical module according to the present invention is shown.

[0021] Such as figure 1 As shown, the device for automatically adjusting the power level of the QSFP+ optical module includes BMC (Baseboard Management Controller, baseboard management controller), GPIO (General Purpose I / OPorts, general purpose input / output port) expansion module, multiple QSFP+ optical modules connected in sequence , BMC as the management controller, using a group of I2C to expand multiple GPIO ports through the GPIO expansion module, controlling different QSFP+ optical modules to share a ...

Abstract

The invention provides a device and method for automatically adjusting a power level of a QSFP+ optical module. The method comprises the following steps: taking a BMC as a management controller, adopting a set of I2Cs to extend multiple GPIO through PCA9554, and controlling an MODESEL pin of QSFP+ to achieve the function that different QSFP+ optical modules share a set of I2Cs; and meanwhile, controlling an LPMODE pin of QSFP+ by the GPIO to ensure that the state of the LPMODE pin can be real-timely changed according to the power consumption information of the optical modules read by the BMC through the I2Cs. Thereby, the trouble that an REWORK resistor is required when the maximum power consumption is greater than Level 1 can be solved, and the device and method provided by the invention are simple and convenient, and can save manpower and material resources.

Description

technical field [0001] The invention relates to the field of power adjustment of QSFP+ optical modules, in particular to a device and method for automatically adjusting the power level of QSFP+ optical modules. Background technique [0002] In order to meet the increasingly large data exchange and realize people's growing network demands, it is necessary to build more powerful data centers and higher network bandwidth. For the data center, it will face greater demands and urgent changes. With the continuous enrichment of network services and the rapid development of processor technology, Gigabit networks are becoming more and more stretched, while 40G and 100G networks are becoming a mainstream development trend. [0003] In order to be able to monitor the power consumption of the QSFP+ module, the Power Level control of the usual QSFP+ (Quad Small Form-factor Pluggable Plus) module is pulled up through the hardware LPMODE pin to enter the power saving mode, which can satis...
