Troubleshooting an NPC on the SRX1400 Services Gateway


The SRX1400 Services Gateway is not normally equipped with a Network Processing Card (NPC). In most configurations, network processing functions are performed by the NSPC. However, replacing the NSPC with an SRX3000-series SPC and an NPC in slots 1 and 3 is a supported configuration for the SRX1400 Services Gateway.

To troubleshoot an NPC, follow these guidelines:

  • Make sure the NPC is properly seated in the slot and its screws are tightened.

  • Make sure that the double-wide tray is properly installed in the slot.

  • Use the CLI show chassis fpc 3 command with the slot number to check the status of installed NPC.

    As shown in the sample output, the value Online in the column labeled State indicates that the NPC is functioning normally:

    user@host> show chassis fpc 3
  • Use the CLI show chassis fpc 3 detail command for more detailed output.

    user@host> show chassis fpc 3 detail

For further descriptions of the output from the commands, see the Junos System Basics and Services Command Reference.
