Troubleshooting the MX2010 Cooling System
date_range
09-Mar-21
Problem
Description
The following alarms, LEDs, and other conditions indicate a problem with the cooling system:
A red alarm indicates that temperature of the router exceeds the maximum (“temperature hot”) threshold.
Automatic shutdown of the power system was caused by the temperature of the router exceeding the maximum (“temperature hot”) threshold.
A red alarm indicates that a fan failed.
A yellow alarm indicates that the router temperature exceeds the “temperature warm” threshold.
A yellow alarm indicates that one of the fan trays was removed.
One or more fans in a fan tray function at full speed. The CB-RE constantly monitors the temperatures detected by sensors on the midplane and router components, adjusting the speed of the fans as necessary.
Solution
To troubleshoot the cooling system:
Place your hand near the exhaust vents at the back of the chassis to determine whether the fans are pushing air out of the chassis.
If the red alarm LED on the craft interface lights, look at the craft interface display to find the source of the problem. The number of alarm conditions, as well as the source of each alarm, appears on the screen.
If the craft interface display lists only one fan failure and the other fans are functioning normally, the fan is probably faulty and you need to replace the fan tray.
Use the CLI to check the status of the fans. For example, you can issue the following command to get information about the source of an alarm condition:
user@host>show chassis alarmsFor information about the alarms (see Table 1).

Alarm Condition
Solution
Fans
Red
fan-name Failure
A fan has failed.
Replace the fan tray.
Temperature sensors
Red
Temperature Hot
The chassis temperature exceeded the hot temperature threshold. If this condition persists, the router shuts down.
Verify that the room temperature is within acceptable limits.
Verify that there is sufficient air flow.
Verify that the cooling system in the chassis is operating properly.
Temperature sensor failure
A temperature sensor failed.
Contact JTAC
Yellow
Temperature Warm
The chassis temperature exceeded the warm temperature threshold.
Verify that the room temperature is within acceptable limits.
Verify that there is sufficient air flow.
Verify that the cooling system in the chassis is operating properly.
