    Checking PIC Alarms

    To check for PIC alarms:

    1. Checking the Current Chassis Alarms
    2. Display the Error Messages in the System Log file

    Checking the Current Chassis Alarms

    Purpose

    To determine the details of the active PIC alarms.

    Action

    To display current PIC alarms, use the following command:

    user@host> show chassis alarms

    Sample Output

    user@host> show chassis alarms
    1 alarms currently active
    Alarm time               Class  Description
    2002-04-08 10:01:20 PDT  Major  PIC 0/2 failed to initialize
    

    Meaning

    The command output displays the alarm time, severity level, and description.

    You can also display PIC alarms by using the following command:

    user@host> show chassis craft-interface
    user@host> show chassis craft-interface
    Red alarm:     LED on, relay on
    Yellow alarm:  LED off, relay off
    Host OK LED:   On
    Host fail LED: Off

    Display the Error Messages in the System Log file

    Purpose

    To determine PIC failure by checking the details of the PIC error messages in the system log file.

    Action

    To display PIC error messages in the system log file, use the following command:

    user@host> show log messages | match PIC

    Sample Output

    user@host> show log messages | match PIC
    Apr  8 10:01:20 aspirin scb CM: PIC 0/2, ID 0x0206, hardware error, offlined
    Apr  8 10:01:20 aspirin alarmd[2671]: Alarm set: FPC color=RED, class=CHASSIS, reason=PIC 0/2 failed to initialize
    Apr  8 10:01:20 aspirin fpc0 PIC: PIC 2 discovery error (1)
    Apr  8 10:01:20 aspirin fpc0 CMFPC: Hardware error discovering PIC 2, ID 0x0206
    Apr  8 10:01:21 aspirin scb CM: ALARM SET: (Major) Slot 0: PIC 0/2 failed to initialize
    

    Meaning

    When a PIC fails, the messages system log file records the time the failure or event occurred, the severity level, a code, and a message description. Use the show log messages command to browse error messages that are generated at least 5 minutes before and after a PIC event. You can also use the show log messages | match PIC command to view specific PIC error messages with common information. Use this information to diagnose a PIC problem and to let the Juniper Networks Technical Assistance Center (JTAC) know what error messages were generated and the router events prior to the problem. For more information about system log messages, see the Junos OS System Log Messages Reference.
