LEDs—When the Routing Engine detects an alarm condition, it lights the red or yellow
alarm LED on the craft interface as appropriate. In addition, you can also use the
component-specific LEDs on the craft interface and on the faceplate of a component
to troubleshoot the routing matrix.
LCD—When a red or yellow alarm occurs, the cause of the alarm messages is displayed
on the craft interface LCD. Use the CLI to display more information about the alarm.
Alarm devices connected to the alarm relay contact on the TXP-CIP—When a red or
yellow alarm occurs, it trips the corresponding alarm relay contact on the TXP-CIP.
CLI—The CLI is the primary tool for controlling and troubleshooting hardware, Junos
OS, routing protocols, and network connectivity. CLI commands display information
from routing tables, information specific to routing protocols, and information about
network connectivity derived from the
