Router Chassis Configuration Guidelines

You can configure properties of the router chassis, including conditions that activate the red and yellow alarm LEDs on the router craft interface and SONET/SDH framing and concatenation properties for individual Physical Interface Cards (PICs).

To configure router chassis properties, include the following statements at the [edit chassis] hierarchy level:

Note: Statements at the [edit chassis redundancy] hierarchy level are described in the JUNOS High Availability Configuration Guide.

Note: The configuration statements at the [edit chassis lcc] hierarchy level apply only to a routing matrix. For information about a routing matrix, see TX Matrix Platform and T640 Routing Node Configuration Guidelines and the TX Matrix Platform Hardware Guide.

This chapter describes the following tasks for configuring the router chassis:
