Troubleshooting High-Temperature Conditions
Table 18: Causes of Power Failures
Symptom
Gateway does not power on
Gateway reboots
The gateway has two temperature sensors for monitoring the temperature status in the gateway
chassis. If the gateway temperature exceeds the default maximum threshold limit of 80° C, a red
alarm is raised. The red alarm is cleared only if the temperature is reduced below the lower
threshold limit of 75° C.
To troubleshoot high-temperature conditions, follow these guidelines:
Use the show chassis temperature command to display the temperature of the gateway. This
command displays the current temperature of the gateway from the two temperature sensors.

show chassis temperature
Instance : 0 Current Temperature(in Celcius) : 53
Instance : 1 Current Temperature(in Celcius) : 53
You can view the temperature of each chassis component by issuing the show chassis
environment command.
Use the show chassis environment command to check the temperature and the status of the
power supply in the gateway. As shown in the sample output, the value Current Temperature
corresponding to the Temperature field indicates the temperature of the gateway.

Possible problems
Gateway is not receiving power
Power supply has
malfunctioned
Power source cannot handle
the load
Power supply has
malfunctioned
Actions
The following actions apply to all
possible problems:
1. Verify that all power
connections are correct.
2. Verify that the power supply is
delivering the correct voltage,
current, and wattage to the
gateway.
3. If the gateway still does not
operate, contact Juniper
Networks Customer Service.
The following actions apply to all
possible problems:
