Troubleshooting
IMPORTANT:
•
The barcode on the router chassis contains product information that must be provided to local
sales agent when 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 H3C for permission. Otherwise, H3C shall not be liable for any
consequence.
