3、更換整流模塊

  對(duì)于整流模塊，除更換風(fēng)扇外，建議不要做其它任何維修工作。整流模塊故障后，請(qǐng)按如下步驟更換：

  1) 檢查新整流模塊，看是否有明顯的運(yùn)輸損壞。

  2) 松開艾默生5800a整流模塊的把手固定螺釘。抓住故障整流模塊的把手將模塊往外拉，即可將模塊抽出機(jī)架。此時(shí)請(qǐng)

  3) 盡量小心，剛剛退出工作的模塊外殼表面溫度還很高，注意抓緊模塊以免跌落損壞。

  4) 抓住新整流模塊把手，緩慢將模塊推進(jìn)到機(jī)柜，確保輸入、輸出插座連接良好。模塊運(yùn)行指示燈經(jīng)過短時(shí)延遲后會(huì)

  5) 發(fā)光，風(fēng)扇運(yùn)轉(zhuǎn)。

  6) 檢查新的整流模塊工作是否正常。包括：監(jiān)控模塊是否能識(shí)別新整流模塊；是否和其他整流模塊均流；當(dāng)重新拔出

  7) 該整流模塊時(shí)，觀察監(jiān)控模塊上是否有相應(yīng)告警。若各項(xiàng)檢驗(yàn)都正確，則更換上的整流模塊運(yùn)行正常。

  8) 將把手推進(jìn)前面板以固定該整流模塊。固定r48-5800a整流模塊的把手固定螺釘。

On May 22, 2019, the 3rd Future Network Development Conference was held in Jiangning Future Network Town, Nanjing. The theme of the conference was "Network Global, Win the Future", while last year's theme was "Innovation, Leadership, Future". If we are still in the turbulent period of transition in 2018, after one year's practice and precipitation, both the government, b operators, equipment manufacturers, relevant representatives and leaders of Internet companies, as well as experts and scholars in the field of network, have a better understanding of the needs and concepts of future network, industrial chain and ecological cooperation.

Last year and this year, what remains unchanged is the infinite future and the common pursuit of the future network, and what changes is the new needs and challenges that arise with practice.

From more than a decade ago, when we realized that the Internet was going to change, to the establishment of Jiangning Institute of Network Innovation in the future in 2011, and to the present "decisive" moment, there may be some differences on the specific realization of white box, marginalization, virtualization and other business issues, but the existing network system has reached an inevitable moment of change, on which all the colleagues of the General Assembly have reached agreement.

IP Overburdened Needs to Update the System by Subversive Means

The first problem is the architecture. Modern network can no longer carry data exchange in the era of big data and AI. The structure decides the nature. According to Wu He-quan, academician of Chinese Academy of Engineering, network protocol (IP) only considers supporting connectionless data communication at the beginning of its design. This is the weakness of the original communication network, and the data traffic in the network at that time accounted for a small proportion. In addition, IP open architecture can be operated on any digital network (including circuit-switched SPC bephone network). There is no special requirement for the underlying communication facilities. It has a wide living space. Moreover, the Internet has begun to be small and there is no pressure for commercialization.

But now, the network is becoming more and more responsible, IP is forced to bear the data needs of the whole world. It takes both time and human and financial resources to start on demand and repair the evolution route. The accompanying problems of extensibility, security, network service and quality can not be ignored. Therefore, "we prefer to rely on the revolutionary line and use subversive technology to update the existing system."

Of course, change does not mean that all this, the reality of the overall transbation program is difficult to verify. According to Cisco's white paper "Global Cloud Index: Forecast and Methodology (2016-2021, White Paper), released at the end of last year, mobile IP traffic accounted for 11.03% of the total network IP traffic in 2018, and the impact of the transbation of mobile network system on the whole network was not particularly significant. Therefore, in today's "mobile traffic proportion is not high", just as VoIP has subverted the penetration of traditional becommunication network technology, Wu Hequan believes that "5G can be used as the breakthrough point of network reb."

The demand of 5G application scenarios for UWB, Dalian connection, low delay and high reliability also echoes the basic requirements of the future network system. The three characteristics of 5G network forwarding, cloud and virtualization can correspond to the integration of communication and computing, the collaboration of cloud management functions and the decoupling of hardware and software. They are not separated from the IP system, nor are they limited to the IP system. They include various new network architecture, such as inbation center network, service customization network, and so on. They compleby change the working mode of the existing TCP/IP network. It includes all kinds of key and hot technologies related to the network, such as new networking technology, network protocol upgrade, as well as new technologies such as artificial inbligence to solve the existing network problems.

This open system, which integrates "evolution and revolution", can ensure that new business needs are met in the short term, and that the existing network problems are solved comprehensively and thoroughly in the long term, so as to promote the development of the digital inbation society.

Change with Pain and Innovation

But change also means the game of interests between upstream and downstream parties. He pointed out that for operators, this is also a difficult choice, and they need to face the challenge of technology and management process reengineering at the same time.

Taking edge computing, one of the core technologies of 5G as an example, as an important direction of the future network, data services can be handled quickly and automatically near the user side, which makes the data interb between mobile communication network, Internet and Internet of Things more convenient and flexible, makes operators more close to users, solves the problem of service rigidity of operators by a large margin, and avoids operation. However, the diversification and fragmentation of access and business needs will al
