See Drill Scenarios (Appendix 1 attached hereof) for detailed arrangements.

II. Communication parameters

The Exchange will apply its official trading system to this testing, and relevant communication parameters are made public in the Notice on the Releasing of Access Parameters of Beijing Data Center ( SQJJSZ[2010] No.237), http://tsite.shfe.com.cn/docview/docview_9117039.htm), which are reiterated as follows: 　

　　All members shall use the FENS mechanism in their trading system to acquire the addresses for the trading and data front-end processors of the Exchange.

　　FENS server IP addresses: 192.168.11.31 and 192.168.11.32 for Shanghai Futures Tower Data Center; 192.168.12.41 and 192.168.12.42 for Zhangjiang Data Center; and 192.168.16.31 and 192.168.16.32 for Beijing Data Center.

　　TCP port and SSL port of FENS server for trading front-end processor addresses: 4901 and 4911; TCP port and SSL port of FENS server for data front-end processor addresses: 4903 and 4913.

　　All members shall add the access network segments of Exchange’s data centers (i.e. 192.168.9.0, 192.168.11.0, 192.168.12.0, 192.168.13.0, 192.168.16.0 and 192.168.17.0) into the routing lists of relevant hosts and routers.
