CDM-Qx Satellite Modem	Revision 5
Ethernet Management (Base Modem)	MN/CDMQx.IOM

To see the installed cards in the chassis, click Quick View under Config Mdm. It should be noted that the user needs to wait for the whole page to display, that is, the left-hand side of the page should display at least the word Base. An example is shown below:

As shown on the left-hand side of the web page, the CDM-Qx has two Tx cards and two Rx cards (one Tx and one Rx grouped as modem, and the others are individual Tx and Rx). In this page, the Base is highlighted, that means the current page that is being displayed belongs to the Base. At the center of this page, the sub-menu Config, Status, Test, Utility, allows the user to navigate the Base configuration, status, test, and utilities. For this example, Config is highlighted which means Base configuration. The word Base is being used to designate the common and grouped functions of the installed cards (Tx or Rx).

To see the configuration of the cards which are grouped as modem, just mouse click MD icon (single click only). Clicking any of these icons will be highlighted. As will be shown in the next example is the configuration of the cards grouped as modem.
