1 Overview
The GMC200 is a high performance, cost effective, carrier grade
manageable media converter system, which is intended for applications of the
point-to-point fiber-to-the-premises (FTTx) market.

3 Web-based Management
The Web-based management interface is one of many tools specifically
designed to assist the network manager in creating complex standalone or
network configurations.
This guide describes how to use the Web-based management interface to
configure and maintain your GMC200 media converter system. It is intended
for network managers who are responsible for configuring the system. This
guide assumes prior knowledge and understanding of the terminology,
theories, and practices and specific knowledge about the networking devices,
protocols, and interfaces that comprise your network.
You should have working knowledge of the Microsoft* Windows*
operating system, graphical user interfaces (GUIs), and Web browsers.
GMC200 provides the default network settings for the Web browsers as
follows. It offers three different login privileges: superuser, admin and guest.
You can change the following parameters at any time after you have
successful logged into the system.
