Troubleshooting
NOTE:
•
The barcode stuck on the router chassis contains information about production and servicing. Before you
return a faulty router for serving, please provide the barcode information of the router to your local sales
agent.
•
An HP tamper-proof label is stuck on a mounting screw on the router chassis. The local sales agent
requires intactness of the tamper-proof label when maintaining the router. Therefore, before you open
the chassis cover, please contact your local sales agent to ask for permission or follow the instruction as
provided by the agent; otherwise, the user takes full responsibility for own operation if any maintenance
failure occurs.
