Overview
     Several kinds of Modules, which can be insered in the standard 19-inch 4.5U standard rack, include the bridge modulars, the fiber modem modulars, the interface converter modulars , the optical bridge modulars and so on. The rack can maxnum hold 16 services modules , or 15 services modulars + 1 management modular, every module can work independently, different type of modules can be mixed into the same rack, this system is safe and reliable. 

Network Management Modular
ME-NMS, the network managemet modular for the 16 slots chassis, it usually be inserted in the 16th slot. It can provide 1 RS232 port and 3 Ethernet ports, customer can freely choose one of the three network management mode, incluing the hyper terminal management, the web management and the integrate NMS software etc.
