Troubleshoot the PTX12008

This topic contains some common troubleshooting resources for the PTX12008 and a list of alarms and how to fix them.

Troubleshooting Resources for PTX12008

Use the messages on the status panel on the front panel and LEDs on the components to identify alarm conditions and the Junos OS Evolved CLI to troubleshoot the device. You can also contact the Juniper Networks® Technical Assistance Center (JTAC) for support.

Status panel—When the device detects an alarm condition, it is displayed on the status panel.
LEDs—When the device detects an alarm condition, the alarm LED on an interface glows red or yellow.
CLI—The CLI is the primary tool for controlling and troubleshooting hardware, Junos OS Evolved, and network connectivity. CLI command outputs display information about network connectivity, which Junos OS Evolved derives from the ping and traceroute utilities. You can use the CLI to see more information about alarm conditions.

For information about using the CLI to troubleshoot Junos OS Evolved, see the appropriate Junos OS Evolved 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 in this guide, contact JTAC.

Table 1: Alarm Terms
Term	Definition
Alarm	A signal alerting you to conditions that might prevent normal operation. On a device, the alarm signal is the red system LED that is lit on the front of the chassis.
Alarm condition	A failure event that triggers an alarm.
Alarm severity	The seriousness of the alarm. The level of severity can be either major or minor.

Alarm Types

Table 2: Alarm Types
Term	Definition
Chassis alarms	A predefined alarm triggered by a physical condition in the device such as a power supply failure or excessive component temperature.
Interface alarms	An alarm that you configure to alert you when an interface link is down. The alarm applies to Ethernet, Fibre Channel, and management Ethernet interfaces. You can set the alarm as major or minor for a specific link-down condition or have the condition ignored.
System alarms	A predefined alarm that might be triggered by a missing rescue configuration, failure to install a license for a licensed software feature, or high disk usage. You can configure system alarms to appear automatically in the J-Web interface display or CLI display.

Alarm Severity

Table 3: Alarm Severity
Term	Definition
Major (red)	Indicates a critical situation on the router that has resulted from one of the following conditions and that requires immediate action: One or more hardware components have failed. One or more hardware components have exceeded temperature thresholds. An alarm condition configured on an interface has triggered a critical warning.
Minor (amber or blinking red)	Indicates a noncritical condition in the router that, if left unchecked, might cause an interruption in service or degradation in performance. A minor alarm condition requires monitoring or maintenance. For example, a missing rescue configuration generates a minor system alarm.

Table 4 documents the chassis alarm messages on the PTX12008, their severity levels, and the actions you can take to respond to them.

Table 4: Alarm Conditions on the PTX12008
Component, Operation, and Chassis Condition	Alarm Condition	Severity	Remedy
Routing Control Board (RCB)	An RCB has failed.	Major (red)	Replace the failed RCB.
Routing Control Board (RCB)	An RCB has been removed.	Minor (yellow)	Install an RCB in the empty slot.
Flexible PIC Concentrator (FPC)	An FPC is offline.	Minor (yellow)	Check the FPC. Remove and reinstall the FPC. If the alarm recurs, replace the failed card.
	An FPC has failed.	Major (red)	Replace the failed FPC.
	An FPC has been removed.	Major (red)	Install an FPC in the empty FPC slot.
Fan tray	A fan tray has been removed from the chassis.	Major (red)	Install the missing fan tray.
	One fan in the chassis is not spinning or is spinning below required speed.	Major (red)	Replace the fan tray.
	A fan is not receiving power.	Major (red)	Check the power supply.
Power supply modules (PSMs)	A PSM has been removed from the chassis.	Minor (yellow)	Install a PSM in the empty slot.
	A PSM has a high temperature.	Major (red)	Replace the failed PSM.
	A PSM input has failed.	Major (red)	Check the PSM input connection and the power cord.
	A PSM output has failed.	Major (red)	Check the PSM output connection.
	A PSM has failed.	Major (red)	Replace the failed PSM.
	Both AC/HVAC/HVDC and DC PSMs are installed in the same chassis.	Major (red)	Do not install AC/HVAC/HVDC and DC PSM in the same chassis.
	Inadequate number of PSMs.	Major (red)	Install the required number of PSMs.
Temperature	The chassis temperature has exceeded 104 °F (40 °C), the fans have been turned on to full speed, and one or more fans have failed.	Minor (yellow)	Check room temperature. Check airflow. Replace the fan tray.
	The chassis temperature has exceeded 149 °F (65 °C), and the fans have been turned on to full speed.	Minor (yellow)	Check room temperature. Check airflow. Check the fans.
	The chassis temperature has exceeded 149 °F (65 °C), and a fan has failed. If this condition persists for more than 90 seconds, the router will shut down.	Major (red)	Check room temperature. Check airflow. Check the fans.
	Chassis temperature has exceeded 167 °F (75 °C). If this condition persists for more than 90 seconds, the router will shut down.	Major (red)	Check room temperature. Check airflow. Check the fans.
	The temperature sensor has failed.	Major (red)	Open a support case using the Case Manager link at https://www.juniper.net/support/ or call 1-888-314-5822 (toll free, US & Canada) or 1-408-745-9500 (from outside the United States).
