Chassis Status	Status of the router chassis: OK (green)—Normal operation Failure (red)—Failed
Chassis Component Temperature
Name	Chassis component. For J-series Services Routers, the chassis components are the Routing Engine and the fans.
Gauge Status	Status of the temperature gauge on the specified hardware comzponent.
Temperature	Temperature of the air flowing past the hardware component.
Chassis Fan Status
Name	Chassis component. For J-series Services Routers, the chassis components are the Routing Engine, the Physical Interface Module (PIM) slot number (identified in the display as an FPC), and the PIM number (identified in the display as a PIC).	On J-series Services Routers, an FPC and a PIM are the same physical unit. The PIM number is always 0.
Status	Status of the fans that are regulated by JUNOS software with enhanced services: OK Testing (when the router is powered on) Failed Absent
Fan Speed	Speed of the fans: normal or high speed.	Speed is adjusted automatically according to the current temperature.
Chassis Power Supplies
Name	Chassis component. For J-series Services Routers, the chassis components are the Routing Engine, the Physical Interface Module (PIM) slot number (identified in the display as an FPC), and the PIM number (identified in the display as a PIC).	On J-series Services Routers, an FPC and a PIM are the same physical unit. The PIM number is always 0.
Power Supply Status	Status of the power supply.
Temperature	Temperature of the air passing by the PIM, in degrees Celsius or in both Celsius and Fahrenheit.

Debug/Info/Notice (green)—Indicates conditions that are not errors but are of interest or might warrant special handling. Warning (yellow)—Indicates conditions that warrant monitoring. Error (blue)—Indicates standard error conditions that generally have less serious consequences than errors in the emergency, alert, and critical levels. Critical (pink)—Indicates critical conditions, such as hard drive errors Alert (orange)—Indicates conditions that require immediate correction, such as a corrupted system database. Emergency (red)—Indicates system panic or other conditions that cause the routing platform to stop functioning.
