The fans in the fan tray are not functioning normally.
To troubleshoot the cooling system:
Check the alarm LEDs on the HCM:
1.
If the yellow or red alarm LED on the HCM is lit, issue the
command to view a more detailed description of the alarm cause:
user@host> show chassis alarms
For a list of messages that can appear in the output, see Table 15 on page 93.
If all the LEDs on the HCM are not lit, it might indicate that power is not being
provided to the router. See "Troubleshooting the M10i Power System" on page 95.
In some cases, the Routing Engine shuts down the router by turning off the power
supplies if the temperature passes the acceptable maximum.
Check the status of the cooling system by issuing the
2.
command. The output includes an entry for each fan and temperature for components,
as shown in this example:
user@host> show chassis environment
