1 Background IT and IP promote the rapid development of enterprise information, and information technology development will further promote the enterprise business development. With the constant expansion of the enterprise network, the business types that network supports are constantly increasing. Network that supports enterprise integrated business becomes a key element of the network and is also a risk factor for business continuity. This requests more on enterprise wide area network. We must enhance its reliability, security, and operation and maintenance of enterprise wide area network, so as to reduce the risk of business disruption. According to the analysis of authoritative organizations, more than 50% of world s network outages and failures are caused by power supply problems; these network outages inflicted thousands of economic loss to the enterprises. Reliable network energy power supply devices are inevitable and necessary. At the same time, reducing energy consumption and carbon emissions has become a global consensus and trends. All governments have integrated energy-saving and emission-reducing into their policy agenda and national planning, while all trades and professions have also developed and signed the corresponding planning and protocols. Efficient and reliable, green and energy-saving are drastically changing the status quo that all trades and professions last for decades. As a leading solutions provider, Huawei launched customized WAN green energy solutions, committed to create efficient, reliable and green energy to help our customers build a solid network and protect customers efficient investment on energy. 1
