Troubleshooting the QFX5130-32CD Switch
QFX5130-32CD Troubleshooting Resources Overview
To troubleshoot a QFX5130 problem, you can use:
Junos Evolved OS CLI
The CLI is the primary tool for controlling and troubleshooting hardware, Junos OS, routing protocols, and network connectivity. CLI commands display information from routing tables, information specific to routing protocols, and 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.
Alarms and LEDs on the network ports, management panel, and components
When the Routing Engine detects an alarm condition, it lights the red or yellow alarm LED on the management panel as appropriate. In addition, you can also use component LEDs and network port LEDs to troubleshoot the QFX5130-32CD switch. For more information, see QFX5130-32CD Management Panel.

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.

QFX5130-3CD Alarm Messages Overview
When a QFX5130-32CD switch detects an alarm condition, it lights
the red or yellow alarm LED on the management panel as appropriate.
To view a more detailed description of the alarm cause, issue the show system alarms operational CLI command.
user@host> show system alarms 2 alarms currently active Alarm time Class Description 2019-01-22 16:32:54 PST Major PEM 1 Absent 2019-01-22 16:31:04 PST Minor Host 0 Disk 2 Labelled incorrectly
For thermal problems, the show chassis temperature-thresholds CLI command shows the cutoff temperatures for each level of alarm:

It is also helpful to calculate the percentage of fan RPM, or duty cycle, use the following in root:
root@re0.~#i2cget -y -f 13 0x66 0x11 0x07
In this example, the system returned the hexadecimal value 0x07. Convert that value to decimal, which is 7 in
this example. Then use this formula to get the duty cycle:
Duty cycle = (value returned + 1)*6.25%
In this example, duty cycle = (7 +1)*6.25 = 50%
Chassis Alarm Messages
Chassis alarms indicate a failure on the device or one of its components. Chassis alarms are preset and cannot be modified.
Chassis alarms on QFX5130-32CD devices have two severity levels:
Major (red)—Indicates a critical situation on the device that has resulted from one of the conditions described in Table 1. A red alarm condition requires immediate action.
Minor (yellow)—Indicates a noncritical condition on the device that, if left unchecked, might cause an interruption in service or degradation in performance. A yellow alarm condition requires monitoring or maintenance.
Table 1 describes the chassis alarm messages on QFX5130-32CD.
Junos OS Evolved systems, such as QFX5130-32CD, are based on a new alarm infrastructure, not all power supplies and fan alarms are supported. Table 1 shows these alarms.
Component |
Alarm Type |
CLI Message |
Recommended Action |
|---|---|---|---|
Fans |
Red (major) |
|
Install fan modules in the slots where they are absent. |
|
Remove and check fan module for obstructions. Reinsert the fan module. If the problem persists, replace the fan module. |
||
sensor-location Temp Sensor Too Hot |
Check the environmental conditions and alarms on other devices. Ensure that environmental factors (such as hot air blowing around the equipment) do not affect the temperature sensor. If the condition persists, the device might shut down. |
||
Yellow (minor) |
|
Remove and check fan module for obstructions. Reinsert the fan module. If the problem persists, check the system log for the message related to the sensor and report the message to customer service. |
|
sensor-location Temp Sensor Too Warm |
Check the environmental conditions and alarms on other devices. Ensure that environmental factors (such as hot air blowing around the equipment) do not affect the temperature sensor. |
||
Power Supplies |
Red (major) |
|
Install a power supply into the empty slot and ensure the power supply is powered. |
Temperature sensors |
Major (red) |
|
Check environmental conditions and alarms on other devices. Ensure that environmental factors (such as hot air blowing around the equipment) do not affect the temperature sensor. if the condition persists, the device might shut down. |
Minor (yellow) |
|
Check environmental conditions and alarms on other devices. Ensure that environmental factors (such as hot air blowing around the equipment) do not affect the temperature sensor. |
|
|
Check the system log for the following error message and report the message to customer support: |
||
Routing Engine |
Major (red) |
|
File storage is at capacity. Reduce unnecessary files to free space. |
Minor (yellow) |
|
File storage is reaching capacity. Reduce unnecessary files to free space. |
|
Management Ethernet interface |
Major (red) |
|
Check whether a cable is connected to the management Ethernet interface, or whether the cable is defective. Replace the cable, if required. |
