Troubleshooting
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.
