Troubleshooting Hardware Components on the SRX550 Services Gateway

This section includes the following topics:

Troubleshooting with the CLI on the SRX550 Services Gateway

The Junos OS command-line interface (CLI) is the primary tool for controlling and troubleshooting services gateway hardware, the Junos OS, routing protocols, and network connectivity. The CLI commands display information from routing tables, information specific to routing protocols, and information about network connectivity derived from the ping and trace route utilities.

You need to enter the CLI commands on one or more external management devices connected to the services gateway to display the information.

Troubleshooting with LEDs on the SRX550 Services Gateway

The LEDs available on the services gateway display the status of various components. Table 27 describes the LEDs on the chassis.

Table 27: Component LEDs on the Services Gateway Chassis

LED

Location

Usage

ALARM

Left side of the front chassis panel

The ALARM LED has the following indicator colors:

  • Red and steadily on indicates a hardware component or software module failure, or detection of a firewall attack.
  • Amber and steadily on indicates a major alarm, such as low memory (less than 10% remaining), session full, maximum number of VPN tunnels reached, high availability (HA) status change, or redundant group member not found.
  • Off indicates that the device is starting up.

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

STATUS

Left side of the front chassis panel

The STATUS LED has the following indicator colors:

  • Green and steadily on indicates that the services gateway is functioning normally.
  • Red and steadily on indicates that the services gateway has failed.
  • Amber and steadily on indicates that the services gateway is starting up, running diagnostics, or shutting down.
  • Off indicates that the device is not receiving power.

POWER

Left side of the front chassis panel

The POWER LED has the following indicator colors:

  • Green and steadily on indicates that all power supply units (PSUs) are functioning normally.
  • Red and steadily on indicates failure of one or more PSUs.
  • Amber and steadily on indicates that the Power button has been pressed. The services gateway will shut down gracefully.
  • Off indicates that the device is not receiving power.

HA

Left side of the front chassis panel

The HA LED has the following indicator colors:

  • Green and steadily on indicates all configured high availability links are available.
  • Red and steadily on indicates cluster member missing or unreachable.
  • Amber and steadily on indicates that some configured high availability links are down, but enough links are still active for full high availability functionality. In this situation performance might be reduced, current bandwidth could cause packet drops, or single point of failure might now exist.
  • Off indicates that HA is not enabled.

ACE

Left side of the front chassis panel

Note: ACE LED is not functional.

RPS

Left side of the front chassis panel

Green and steadily on indicates that the redundant power supply is operating normally.

Red and steadily on indicates that one of the following conditions has occurred:

  • The primary power supply has failed, and the device is being powered by the redundant power supply.
  • The redundant power supply has been installed, but is not connected to a power source.

MPIM-1 and MPIM-2

Left side of the front chassis panel

Green and steadily on indicates that the Mini-PIM in the corresponding slot is functioning normally.

Red and steadily on indicates that the Mini-PIM hardware in the corresponding slot has failed or its anti-counterfeit check failed.

Off indicates that there is no Mini-PIM in the corresponding slot, or that the Mini-PIM is not detected by the device.

Troubleshooting with Chassis and Interface Alarm Messages on the SRX550 Services Gateway

When the services gateway detects an alarm condition, it lights the red or yellow alarm LED on the front panel as appropriate. For a detailed description of the alarm condition, issue the show chassis alarms CLI command.

There are two classes of alarm messages:

Examples:

user@host# run show chassis alarms

For more information about the show chassis alarms command, see the Junos OS Monitoring and Troubleshooting Guide for Security Devices PDF Document.

Table 28 describes alarms that can occur for a services gateway chassis component.

Alarm Conditions

Alarm Severity

Boot media

The services gateway boots from an alternate boot device.

If the internal flash fails at startup, the services gateway automatically boots itself from the alternative boot device (USB storage device).

If you configured your services gateway to boot from an alternative boot device, ignore this alarm condition.

If you did not configure the services gateway to boot from an alternative boot device, contact JTAC.

Yellow (minor)

Gigabit-Backplane Physical Interface Module (GPIM)

A GPIM has failed.

Contact JTAC.

See Juniper Networks Technical Assistance Center

Red (major)

Hardware components on the services gateway

The services gateway chassis temperature is too high.

Yellow (minor)

The services gateway fan has failed.

Place your hand near the exhaust vents at the rear of the chassis to determine whether the fan is pushing air out of the chassis.

Replace the failed fan and contact JTAC.

Red (major)

Note: For more information about alarms, see the Junos OS Monitoring and Troubleshooting Guide for Security Devices PDF Document.

Troubleshooting the Power System on the SRX550 Services Gateway

The LEDs on the services gateway enable you to determine the performance and operation of the power system. The POWER LED located on the front panel of the services gateway, as described in Table 29, indicates the different status settings with respect to the power system. The LEDs on the faceplate of each power supply also show power supply status as described in Table 30.

Table 29: POWER LED Description

LED Status

LED State

Meaning

Possible Cause and Corrective Action

Green

On

The services gateway is receiving power, and all AC and/or DC power supply units (PSUs) are working properly.

Normal indication. No action is required.

Red

On

Indicates failure of one or more PSUs.

If you cannot determine the cause of the problem or need additional assistance while troubleshooting a services gateway, open a support case using the Case Manager link at http://www.juniper.net/support/, or call 1-888-314-JTAC (within the United States) or 1-408-745-9500 (outside the United States).

Amber

On

Power button has been pressed. The services gateway will shut down gracefully.

Once the services gateway is running again, continue troubleshooting.

 

Off

Indicates that the services gateway is not receiving power.

If a red alarm condition occurs, issue the show chassis alarms command to determine the source of the problem.

  • Verify that the AC power cord and/or DC power supply cable is not damaged. If the insulation is cracked or broken, immediately replace the cord or cable.
  • Verify that the source circuit breaker has the proper current rating. Each power supply must be connected to a separate source circuit breaker.
  • Ensure that the power socket you are plugged into is in working condition.
  • Connect the power supply to a different power source with a new power cord or power cables. If the power supply status LEDs indicate that the power supply is not functioning normally, the power supply is the source of the problem. Replace the power supply with a spare.

Note: If the system temperature exceeds the threshold, the Junos OS shuts down all power supplies so that no status is displayed.

The Junos OS also can shut down one of the power supplies for other reasons. In this case, the remaining power supplies provide power to the services gateway, and you can still view the system status through the CLI.
