    Checking the FPC Status

    To check the FPC status:

    Check FPC Status and Utilization

    Purpose

    To confirm that the FPC is functioning properly by checking the status and utilization information for all FPCs installed in the router.

    Action

    To display brief status and utilization information for FPCs installed in the router, use the following operational mode command:

    user@host> show chassis fpc

    Sample Output

    user@m160> show chassis fpc
    Temp  CPU Utilization (%)   Memory    Utilization (%)
    Slot State            (C)  Total  Interrupt      DRAM (MB) Heap     Buffer

    Meaning

    Use the show chassis fpc command to identify whether there is a problem with any of the FPCs installed in the router. The command output displays a brief status of all the FPCs installed in the router. The state can be online, dead, diag, dormant, empty, online, probed, or probe-wait. If the FPC state is dead, an alarm occurs. For more detailed information about the FPC states, see the Junos OS Routing Protocols Configuration Guide, Class of Service Configuration Guide, and Junos OS System Basics and Services Command Reference.

    The temperature is that of the air flowing past the FPC. If the temperature is too high, an alarm occurs.

    The CPU and memory information is the total percentage of CPU being used by the FPC processor, the total CPU being used by the FPC processor, the percentage of CPU being used for interrupts, and the total DRAM available to the FPC processor. The percentage of heap space (dynamic memory) reflects the buffer space being used by the FPC processor. If the heap space exceeds 80 percent, there might be a software problem (memory leak).

    The output also displays the percentage of buffer space being used by the FPC processor for buffering internal messages.

    Check FPC Status and Uptime

    Purpose

    To verify FPC error conditions by checking the FPC status and uptime for a particular FPC slot.

    Action

    To display the status and uptime for a particular FPC slot, use the following command:

    user@host> show chassis fpc detail fpc-slot

    Sample Output

    user@M160> show chassis fpc detail 3
    Slot 3 information:
      State                               Online    
      Temperature                      36 degrees C / 96 degrees F
      Total CPU DRAM                   32 Mbytes
      Total SRAM                        4 Mbytes
      Total SDRAM                     256 Mbytes

      Uptime:                             6 days, 1 hour, 19 minutes, 36 seconds
    

    Meaning

    The command output shows status information for the FPC in slot 3, including the operating state. The state can be online, dead, diag, dormant, empty, online, probed, or probe-wait. If the FPC state is dead, an alarm occurs. For more detailed information about the FPC states, see the Junos OS Routing Protocols Configuration Guide, Class of Service Configuration Guide, and Junos OS System Basics and Services Command Reference. The command output also shows temperature, memory usage, I/O Manager application-specific integrated circuit (ASIC) version level, start time, and uptime. The uptime is important to determine how long the FPC has been operational. A small uptime means that the FPC came online a short time ago and could indicate a possible FPC error condition.

    show chassis fpc <pic-status < fpc-slot >> show chassis fpc <detail < fpc-slot >>

    Checking FPC Status and Temperature

    Purpose

    (M40e, M160, M320, T320, and T640 router only) To verify FPC error conditions by checking the FPC status and temperature for a particular FPC slot.

    Action

    To display the FPC status and temperature for a particular FPC slot, use the following command:

    user@host> show chassis environment fpc fpc-slot
    user@m160> show chassis environment fpc 0
    FPC 0 status:
      State                           Online
      Temperature                  39 degrees C / 102 degrees F
      Power:
        1.5 V                    1496 mV
        2.5 V                    2485 mV
        3.3 V                    3306 mV
        5.0 V                    4991 mV
        5.0 V bias               4993 mV
        8.0 V bias               8251 mV
      CMB Revision                 12
    

    Meaning

    The command output displays the status of the FPC in slot 0, including the state, temperature, voltage levels on the FPC, and the revision level of the chassis management bus backup. The state can be Unknown, Empty, Present, Ready, Announce online, Online, Offline, or Diagnostics. An Offline state indicates an FPC error condition.

    Checking FPC Status and Temperature in a T1600 Router

    Purpose

    To verify FPC error conditions by checking the FPC status and temperature for a particular FPC slot in a T1600 router.

    Action

    To display the FPC status and temperature for a particular FPC, issue the show chassis fpc command . As shown in the sample output, the value Online in the column labeled State indicates that the FPC is functioning normally:

    user@host> show chassis fpc
                         Temp  CPU Utilization (%)   Memory    Utilization (%)
    Slot State            (C)  Total  Interrupt      DRAM (MB) Heap     Buffer
      0  Online            37      2          0       256         9         41
      1  Empty           
      2  Online            37      3          0       256         8         41

      6  Empty           
      7  Empty           
    

    For more detailed output, add the detail option. The following example also specifies a slot number (0), which is optional:

    user@host> show chassis fpc detail 0
    Slot 0 information:
      State                               Online    
      Temperature                      37 degrees C / 98 degrees F
      Total CPU DRAM                  256 MB
      Total SRAM                       28 MB
      Total SDRAM                     256 MB
      Start time:                         2003-10-01 04:19:30 PDT
      Uptime:                              10 days, 7 hours, 16 minutes, 48 seconds

    Checking the FPC LED States

    Purpose

    To confirm that the FPC is functioning properly by checking the FPC LED states or examining the LEDs on the faceplate.

    Action

    To check the FPC LED status, use the following command:

    user@host> show chassis craft-interface

    Sample Output

    user@host> show chassis craft-interface
    [...Output truncated...]
    Front Panel FPC LEDs:
    FPC    0   1   2   3   4   5   6   7
    ------------------------------------
    Red    .   .   .   .   .   .   .   .
    Green  *   *   .   .   .   .   .   .
    [...Output truncated...]
    

    Meaning

    The Front Panel FPC LEDs section displays the status of each FPC. The FPCs have two operational states: Green (OK), and Red (Fail). Asterisks (*) indicate the operating state. Dots indicate an off state for LEDs. If both red and green LEDs have dots, the FPC slot is empty. Asterisks in the Green state indicate that the FPCs in slots 0 and 1 are operating normally. No FPCs are installed in slots 2 through 7.

    (For all routers except the M5, M7i, M10, and M10i) You can also check the FPC status by looking at the LEDs on the faceplate. Each FPC has two LEDs that report its status. Only one LED state can occur at a time. Table 1 describes the FPC LEDs.
