Before the Tomb Sweeping Day, festivals arrive one after another, Shangsi Festival, Cold Food Festival, now people have plenty of time to go outings and meet friends in this pleasant and warm March. It’s really thrilling to just think about the things we could do, to take a bath and then hold sacrifice ceremonies in honor of gods and ancestors, to enjoy ourselves with an outing in a field full of blossoming flowers, soft willow branches, and green grass, to take part in a singing party or wine party, or sports like a swing contest or a football match, or cultural activities like sightseeing and poem-writing over a cup of drink flowing to you along a crook stream, or to meet the loved ones and stroll along streets or riverside walks, or share a smile over a bunch of roses…

In Year 353 A.D, on March 3rd of the 9th Yonghe Year of Easter Jin Dynasty, the world witnessed the most brilliant Shangsi Festival of all in history, the Orchid Assemble of Scholars. On that day, in the Orchid Pavilion on Mount GuijiShang, an excellent group of scholars, old and young, gathered for a small but high-rank academic discussion, including Mr. Xie An, Mr. Sun Chuo, Mr. Xie Wan, Mr. Yu You, and other 30-odd elites from upper class and noble families. After the gathering, Mr. Wang Xizhi, the greatest calligrapher of all times, wrote an article to summarize the whole event, i.e. the Orchid Pavilion Preface. After the agenda was finished, in high spirits, people held a ‘Floating Cup’ game, in which a cup of drink is released into a winding channel where there are many man-made turnings which might stop the cup floating along the stream. When the cup is stopped, the scholar who happens to sit at the turning would take it, drink it, write a poem or dink more as a punishment if he couldn’t write one.

By Tang Dynasty when China was in another prime time of economy, culture and military power, the Shangsi Festival also became more important and was all the more celebrated by all people from top class to the poorest ones. As a matter of fact, the imperial court issued a special imperial edict to ensure court officials not only have the free time for the festival, but also the money, in the form of emperor’s reward, to celebrate it. So, in that time, court officials could enjoy the festival in a very decent, admirable, comfortable and free way. 

Just as said in an ancient poem, ‘In a good day on March third, come more beauties strolling riverbanks in Chang’an’, in this Shangsi Festival, the IDX LanGuang Data Center released a notice, LanGuang High and Low Voltage Distribution Cabinet Out of Service for Maintenance. It is actually a part of SDS power supply improvement plan. A maintenance and upgrading action will take place in summer and autumn to ensure and improve the SAL of power supply. 

Let me put everything in one word. The coming Tomb Sweeping Festival is a great time for people to enjoy the spring to heart’s content. Allow me, the SDS news editor, to quote this line as my best wishes to all readers: ‘With happy smiles on faces, with the loved ones aside, let’s enjoy this spring day in Shangsi Festival”. 

Please see it as an on-site test. It’s a good opportunity for you to understand how well your system could react in an emergency. Also, it’s a good time to see if your dual power supply units could really switch between two power sources seamlessly. Please be fully prepared before you start the test. That’s the right way to the success. 

首先，您应检查机柜内双电源设备的两个电源是否分别插在两路不同PDU条上。只有两个电源插在不同PDU条上，您的双电源设备才能真正起到双电源的作用。

（请不要忽视这一检查，按照我们的经验现场施工时经常会使插满一个PDU条再插另外一个PDU条。）

其次，排查所有单电源设备在哪路PDU条上。如不想在维保时断电，我们建议您在您认为可行的时间段，将电源设备切换到不做维保的那路PDU条上。

>>>>Professional, reliable, high SAL Maintenance and Upgrading

Relying on strong technical capacity and professional service capacity to guarantee customer operations, as well as our extensive operating experience accumulated during the provision of various services to customers from different backgrounds over a long period of time, SDS O&M Team is able to successfully complete all maintenance and upgrading tasks while maintaining the normal operation of the entire data center. Currently, the IDX LanGuang Data Center is running as usual. In addition, a prudent assessment has been made to understand the potential risks in this maintenance project. A decision has been made to ensure that, during the maintenance, only one of the two power supply lines of a computer room will be disconnected from the circuit in one maintenance task. That is to say, SDS will and is able to carry out the maintenance project without having any user feeling any interruption. Meanwhile, the SDS O&M Team has already worked out a contingency plant against problems that might happen and will contact and encourage users to make their preparations and backup plans in advance.
