2.1.2 CENTRALIZED MANAGEMENT OF MULTIPLE SERVERS ACROSS INTERNET

Smart Grid can also provide power consumption management to multiple servers when spanning Internet. In this scenario, the corporation network is
divided into two, i.e. LAN and DMZ zone (a large corporation has Extranet and Intranet DMZ zones located in two machine rooms separately) where
the application servers for Internet such as mail server and Web server are located. Every server in DMZ zone is provided with two IP addresses, LAN
address and Internet address, and connects multiple machine rooms by special cables.
Then, Smart Grid server software is installed on a dedicated server in LAN. The end users can monitor the power consumption of servers in LAN and
DMZ zone with the terminal login system in internal LAN, DMZ or Internet, when the network parameters are properly configured.
To ensure that Smart Grid severs can communicate with the servers in DMZ zone, configure the intranet firewall properly and allow normal
communication between the Smart Grid servers and the BMC module of servers in DMZ zone. For the network requirements of this product, please
refer to Section 2.1.3.
If you want to monitor devices by Internet, it is recommended that you can access Intranet by VPN first and then perform operations.
Tips: For safety concern, it is not recommended for users to deploy Smart Grid server on Internet.

2.1.3 SERVER TIME SYNCHRONIZATION REQUIREMENTS

Smart Grid server and the managed server need to maintain synchronization in time, so it is recommended to select a server in the network as a time
server (NTP server) and synchronize the times of other servers with the time of NTP server.
2.1.4 PORT USAGE REQ UIREMENTS OF SMART GRID SERVER
The operation of Smart Grid software requires three TCP ports (TCP port numbers of 6443, 8688 and 8888). Therefore, before the installation, please
make sure that the TCP network ports of the sever are not occupied by other software.
