If the system fault LED shows the over-temperature blink pattern, follow these
steps:
Inspect the chassis air vents. Are the intake and exhaust vents clear?
Yes—Continue.
No—Remove any debris from the fan intake and exhaust if necessary.
If the condition remains, continue.
Consider the ambient air temperature near the router and clearance around
the router. Make necessary corrections. If the condition remains, open a
command line window and log on to the router. Enter the shutdown
command, and then power down the router. Contact your authorized
maintenance provider.
Recovering a Router
You may have to recover a router for one of the following reasons:
The password was changed and has been forgotten.
The router’s management IP address is unknown.
To recover the router’s password, reset the password to the default by using the
maintenance button (see page 1-8).
You can recover the router’s IP address using either of the following methods:
Connect to the serial console port (see page 1-13), and then use the CLI
set mgmt command to reconfigure the management port (see the
iSR6200 CLI User’s Guide).
Use the maintenance button to reset the management port’s IP to the factory
default of 10.0.0.1 (see page 1-8).
