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 Hewlett Packard Enterprise for permission. Otherwise, Hewlett
Packard Enterprise shall not be liable for any consequence.
