On M7i, M10i, and M320 routing platforms, you can use the chassis viewer feature to view images of the chassis and access information about each component similar to what you can obtain using the show chassis alarms and show chassis hardware commands.
To access the chassis viewer, click the Chassis Viewer icon in the upper right corner of any J-Web page for an M7i, M10i, or M320 routing platform. A separate page appears to display the image of the chassis and its component parts, including power supplies, individual Physical Interface Cards (PICs), and ports. Major or minor alarm indicators appear in red.
Figure 2 shows the chassis and components of an M7i routing platform. It also shows the status of each port in red or green, the zoom bar selections, and the View Front and View Back buttons that allow you to toggle between front and rear views of the chassis.
