What to do if the sliding door of the fan bay does not close on a Cisco Network Router?
If the sliding door of the fan bay does not close when the Fan Module is removed, it is likely that the sliding door is stuck. To fix this, push the front flap open and manually slide the door back and forth to ensure free movement. If this does not work, pull the door closed to stop air bypass until a fan module is installed.
Why is the STATUS LED of a fan not illuminated right after powering on a Cisco Network Router?
If the STATUS LED of a fan is not illuminated when the Cisco cBR-8 chassis is powered on, and less than 10 seconds have elapsed since the chassis was powered on, it is normal. The LED will illuminate 10 seconds after the chassis is started up.
What to do if the STATUS LED of a fan is not illuminated after 10 seconds on Cisco cBR?
If the STATUS LED of a fan is not illuminated more than 10 seconds after the Cisco cBR-8 chassis is powered on, there may be a failure of a Fan Module component. Check the status of the LED labeled RPLC. If it is also illuminated, replace the fan module.
