Monitoring the SRX110 Services Gateway Chassis Using the CLI

You can monitor alarms to troubleshoot hardware problems on a services gateway. The chassis properties include the status of active chassis alarms and environment measurements on the device.

To view these chassis properties, select Monitor in the J-Web interface, or enter the following CLI show commands:

Examples

The following examples provide the sample output of commands:

Monitoring the SRX110 Services Gateway Components Using LEDs

You can monitor the chassis condition by using the LEDs. Table 39 lists the LEDs, their condition, the possible causes and corrective actions.

Table 39: Component LEDs on the Services Gateway

LED

State

Meaning

Possible Causes and Corrective Actions

Status LED

Green

Indicates that the device is functioning normally.

Normal condition. No action is required.

Amber

  • The device is starting up.
  • The Reset Config button is pressed.

Normal condition. No action is required.

Red

Indicates an error in the device.

Contact the Juniper Networks Technical Assistance Center (JTAC). See Juniper Networks Technical Assistance Center.

Alarm LED

Green

Indicates that the device is functioning normally.

Normal condition. No action is required.

Red

The device indicates a critical alarm.

A critical alarm indicates a critical situation on the gateway that requires immediate action.

See Monitoring the SRX110 Services Gateway Using Chassis Alarm Conditions.

Amber

The device indicates a major alarm.

A major alarm requires monitoring or maintenance. If left unchecked, it might cause an interruption in service or degradation in performance.

See Monitoring the SRX110 Services Gateway Using Chassis Alarm Conditions.

Off

The device is starting up.

Note: When the system is up and running, if the Alarm LED is off, it indicates that no alarms are present on the device.

Normal condition. No action is required.

Power LED

Green

The device is receiving power and is functioning normally.

Normal condition. No action is required.

Amber

The Power button has been pressed and quickly released.

Normal condition. No action is required.

Off

The device is not receiving power.

Normal condition if the services gateway is switched off. No action is required.

If you have not powered off the services gateway, verify that the AC power cord from the power source to the device is not damaged, the socket is in working condition, and the device has an AC input voltage between 110 and 240 VAC.

See Monitoring the SRX110 Services Gateway Power System.

Monitoring the SRX110 Services Gateway Using Chassis Alarm Conditions

When the services gateway detects an alarm condition, the alarm LED on the front panel turns red or amber as appropriate.

To view a more detailed description of the cause of the alarm , issue the show chassis alarms CLI command.

For more information on the show chassis alarms command, see the following guides:

Table 40 describes alarms that can occur for an SRX110 Services Gateway chassis component.

Alarm Severity

Boot media

The services gateway boots from an alternate boot device.

Amber (minor)

Hardware components on the services gateway

The services gateway chassis temperature or chassis is too warm.

Amber (minor)

The services gateway temperature is too high, either because of an internal overheating condition or because the maximum recommended room temperature has been exceeded.

The services gateway shuts down automatically in 4 minutes.

Red (major)

Monitoring the SRX110 Services Gateway Power System

The LEDs on the services gateway enable you to determine the performance and operation. The Power LED, located on the front panel of the services gateway, indicates the different settings with respect to the power system.

Table 41 describes different Power LED status settings and their corrective actions.

Table 41: Services Gateway Power LED Status

Status

Meaning

Possible Cause and Corrective Action

Green

The device is receiving power, and the internal power supply is functional.

Normal indication. No action is required.

Amber

The Power button has been pressed and quickly released. The device is shutting down or starting up.

Normal indication. No action is required.

Off

The device is not receiving power.

  • Verify that the AC power cord from the power source to the device is not damaged. If the insulation is cracked or broken, immediately replace the cord or cable.
  • Ensure that the socket you plug in is in working condition.
  • Ensure the device has an AC input voltage between 110 and 240 VAC.
  • If you cannot determine the cause of the problem or need additional assistance, contact the Juniper Networks Technical Assistance Center (JTAC). See Juniper Networks Technical Assistance Center.
