The correct answers to investigate a Junos device experiencing temperature-related problems are A. show chassis hardware and D. show chassis environment.
Here's a detailed explanation for each command:
A. show chassis hardware command displays the hardware inventory of the device, including the temperature sensors, fans, power supplies, and other components. Running this command can give an overall idea of the health of the hardware components and identify any components that may be failing or causing temperature issues.
Example output:
sqluser@device> show chassis hardware Hardware inventory: Item Version Part number Serial number Description Chassis XYZ1234 SRX345 Midplane REV 05 750-043332 XYZ1234 SRX345 Midplane FPC 0 REV 10 750-044961 XYZ1234 SRX5k SPC 2 CPU BUILTIN BUILTIN BUILTIN FPC CPU PIC 0 BUILTIN BUILTIN 10x 1G SFP PIC 1 BUILTIN BUILTIN 2x 10G SFP+ PIC 2 BUILTIN BUILTIN 2x 10G SFP+ FPC 1 REV 10 750-044961 XYZ1234 SRX5k SPC 2 CPU BUILTIN BUILTIN BUILTIN FPC CPU PIC 0 BUILTIN BUILTIN 10x 1G SFP PIC 1 BUILTIN BUILTIN 2x 10G SFP+ PIC 2 BUILTIN BUILTIN 2x 10G SFP+ Power Supply 0 REV 08 740-046284 XYZ1234 AC Power Supply Power Supply 1 REV 08 740-046284 XYZ1234 AC Power Supply Fan Tray 0 Fan Tray Fan Tray 1 Fan Tray B. show chassis temperature-thresholds command displays the temperature thresholds set for the device. The command shows the minimum and maximum temperatures set for different components of the device, such as the routing engine, switch fabric, and power supplies.
Example output:
sqluser@device> show chassis temperature-thresholds Threshold values: State Current temp Threshold temp Overtemperature 50 degrees C 70 degrees C CB 0 Temp 40 degrees C 60 degrees C CB 1 Temp 45 degrees C 60 degrees C CB 2 Temp 42 degrees C 60 degrees C CB 3 Temp 42 degrees C 60 degrees C FPC 0 Intake 28 degrees C 50 degrees C FPC 0 Exhaust 37 degrees C 70 degrees C FPC 1 Intake 28 degrees C 50 degrees C FPC 1 Exhaust 38 degrees C 70 degrees C C. show chassis pic fpc-slot <value> pic-slot <value> command displays the status of a PIC (Physical Interface Card) installed on an FPC (Flexible PIC Concentrator) slot. This command can be used to check the temperature of a specific PIC.
Example output:
sqluser@device> show chassis pic fpc-slot 0 pic-slot 0 PIC 0 on FPC 0 PIC version: 1.0 State of last resort: Offline Start
