Troubleshooting
IMPORTANT:
The barcode on the router chassis contains product information that must be provided to local sales
agent before you return a faulty router for service.
Keep the tamper-proof seal on a mounting screw on the chassis cover intact, and if you want to open the
chassis, contact HP for permission. Otherwise, HP shall not be liable for any consequence.
