•
the chassis, contact HP for permission. Otherwise, HP shall not be liable for any consequence.
Power supply failure
If the router cannot be powered on and LEDs on the front panel are off, it indicates that the power
supply is faulty.

Verify that the power source is operating properly.
3.

System configuration problems
If the configuration environment setup is correct, the console terminal displays boot information when
the router is powered on. If the setup is incorrect, the console terminal displays nothing or garbled text.
