Troubleshooting the SRX4200

Troubleshooting Resources for the SRX4200 Services Gateway

To troubleshoot a services gateway, use the Junos OS command-line interface (CLI) and LEDs on the chassis:

  • LEDs—When the services gateway detects an alarm condition, the status LED on the front panel glows red.

  • CLI—The CLI is the primary tool for controlling and troubleshooting hardware, Junos OS, and network connectivity. Use the CLI to display more information about alarms. CLI commands display information about network connectivity derived from the ping and traceroute utilities. For information about using the CLI to troubleshoot Junos OS, see the appropriate Junos OS configuration guide.

  • JTAC—If you need assistance during troubleshooting, you can contact the Juniper Networks Technical Assistance Center (JTAC) by using the Web or by telephone. If you encounter software problems, or problems with hardware components not discussed here, contact JTAC.

Monitoring Chassis Alarms on an SRX4200 Services Gateway

You can monitor chassis alarms through the Status LED. When the services gateway detects an alarm condition, the Status LED on the front panel glows red. The level of severity can be either major (steady red) or minor (blinking red). To view a more detailed description of the alarm cause, issue the show chassis alarms command.

Table 1 describes alarms that can occur for the services gateway chassis component.

Alarm Severity

Fan

At least one of the fans have failed.

  • Check and adjust the room temperature, if possible.

  • Check the air flow and ensure that the airflow through the services gateway is unobstructed.

  • Open a support case using the Case Manager link at https://www.juniper.net/support/ or call 1-888-314-5822 (toll-free within the United States and Canada) or 1-408-745-9500 (from outside the United States).

Steady red (major)

The services gateway chassis temperature is too warm.

  • Check the room temperature.

  • Check the air flow.

  • Open a support case using the Case Manager link at https://www.juniper.net/support/ or call 1-888-314-5822 (toll-free within the United States and Canada) or 1-408-745-9500 (from outside the United States).

Yellow (minor)

Power supply

A power supply has failed.

Replace the power supply.

Steady red (major)

A power supply unit is not present.

Install a power supply unit in the empty slot. The services gateway requires two power supply units to be installed.

AC power cord is not connected.

Verify and ensure that the AC power cord is connected properly.

Using the RESET Button on the SRX4200 Services Gateway

If a configuration fails or denies management access to the services gateway, you can use the RESET button to restore the services gateway to the factory-default configuration.

CAUTION:

Pressing and holding the RESET button for 5 seconds or more deletes all configurations (backup configurations and rescue configuration) on the device, and loads and commits the factory configuration.

You can change the default operation of the RESET button by limiting how the button resets the services gateway:

  • To prevent the RESET button from setting the services gateway to the factory-default configuration and deleting all other configurations, enter the following command. You can still press and quickly release the button to reset it to the rescue configuration.

    user@host# set chassis config-button no-clear

  • To prevent the RESET button from setting the services gateway to the rescue configuration, enter the following command. You can still press and hold the button for 15 seconds or more to reset the services gateway to the factory-default configuration.

    user@host# set chassis config-button no-rescue

  • To disable the button and prevent the services gateway from resetting to either configuration, enter the following command:

    user@host# set chassis config-button no-clear no-rescue

The no-rescue option prevents the RESET button from loading the rescue configuration. The no-clear option prevents the RESET button from deleting all configurations on the services gateway.

To return the function of the RESET button to its default behavior, remove the config-button statement from the services gateway configuration.
