Opening/Closing the Chassis Cover
One of the screws fixing the router chassis is covered with an HP dismantlement-preventive
seal. Before providing services on your router, your local dealer requires that the factory seal be
unbroken. Therefore, please contact your local dealer for permission before opening the router
chassis, and follow your local dealer’s instructions. A broken factory seal will result in
unavailability of router services by your local sales agent.
