This is a common task for network engineers aiming to optimize resource allocation and troubleshoot potential power-related issues affecting network stability.
Understanding FPC and Power in Juniper Devices
In Juniper's networking hardware, an FPC, or Flexible PIC Concentrator, is essentially a modular chassis that houses various interface cards (PICs)[SRX] "show chassis fpc" output shows CPU less FPC. These FPCs are critical components that provide the network interfaces for your deviceYou cancheckthe inventory logs, chassisd logs to see what happens whenFPCis installed inslot-0. Another options is move thatFPCto emptyslot, sayslot-1 .... The power supply for these FPCs is managed by the device's power supply units (PSUs). When troubleshooting, particularly concerning fpc 0, it's crucial to examine both the FPC's status and the health of the associated power supplymonitor power usage on EX92xy and QFX10008 devices ....
Checking FPC Power Consumption and Status
The primary command to get an overview of your FPC status is `show chassis fpc`Syslog message: CHASSISD_POWER_CHECK. However, when investigating power consumption specifically, you might need to delve deeper.
* `show chassis fpc`: This command provides a general status update on your FPCs. You can see if fpc 0 is online, offline, or experiencing issues. While it doesn't directly show power consumption in watts for individual FPCs, it's the first step in identifying if an FPC is even recognized by the system.I'm having trouble getting the EX8208 to recognize any of its FPCs. "Show chassis hardware" and "show chassisfpc" don't have anything in them at all.
* `show chassis environment`: This command is vital for understanding the environmental status of your chassis, including power. It can reveal if there are any power supply issues or alarms related to the power delivery to the FPC in slot 0. You might see messages like "CHASSISD_POWER_CHECK" indicating a problem with an FPC not powering up due to issues with the power supply in its associated slot.[SRX] "show chassis fpc" output shows CPU less FPC
* `show chassis hardware`: For a comprehensive hardware inventory, this command can be useful. It allows you to see the installed hardware, including FPCs, and their assigned slot numbersJuniper Commands | PDF.
* `show chassis power detail`: This command offers more granular information regarding the power allocation and consumption within the chassisThis line card has more interfaces than PFEs to support them. Your configuration needs topowerdown the two PICs that you don't need.. To specifically view the power consumption of FPCs, you can pipe the output: `show chassis power detail | grep "FPC"`. This will help you monitor power usage and understand the actual demand from each FPC.
* `show poe interface`: If you are dealing with Power over Ethernet (PoE) on your Juniper switches (like EX Series), this command is essential. It allows you to monitor the Power over Ethernet status for individual interfaces, showing their administrative and operational status, maximum power, and actual power consumption. This is particularly relevant if your FPC is also powering devices via PoEuser@switch> show poe interface Interface Admin Oper Max Priority Power Class status statuspower consumptionge-0/0/0Enabled ON 15.4W Low 7.4W0ge-0/0/1 ....
* `show security monitoring fpc 0`: For SRX series firewalls, this command can provide specific monitoring details for fpc 0, including its CPU and memory utilization. While it might not directly display wattage, understanding resource usage can sometimes correlate with power draw.
Troubleshooting Common Power-Related FPC Issues
Several issues can prevent an FPC from initializing or functioning correctly, often related to power:
* Insufficient Power: The most common culprit is inadequate power supply. If the total power usage of all installed components (including the FPC in slot 0) exceeds the capacity of the PSUs, or if a specific PSU fails, the FPC may not get enough power to start. You might see "FPC absent" or "FPC is not coming online due to insufficient power" messages.Managing Errors | Junos OS In such cases, you need to calculate the power distribution and check power supply status.
* Faulty Power Supply: A Power Supply 0 or Power Supply 1 (depending on your configuration) might be faulty or not properly connected. Messages like "FPC 0 PEM 0 Feed [X] notfpc 0 Empty : r/Juniper...MX Series FPC and PIC Overview - Juniper Networks" or alarms related to non-existent PEMs can indicate this. Check power supply connections and the operational status of individual PSUs.Saving Energy on PTX with PFE Power Off

* Configuration Overrides: In some advanced scenarios, you might use commands like `set chassis fpc
* Redundant Power Scenarios: On devices with redundant power supplies, commands like `show chassis environment` can display the PowerAvailable field, indicating if the switch is meeting N +1 power requirementsUsing the error command, you can classify errors according to severity, set an automatic recovery action for each severity, and configure the actions to perform ....
