Troubleshooting
This appendix provides troubleshooting information for the router.
NOTE:
The barcode on the router chassis contains product information that must be provided to HP Support before
returning a faulty router for service.
The HP tamper-proof label attached to a mounting screw on the router chassis must be kept intact. Before
opening the chassis cover, contact HP Support for authorization; if you do not, you take full responsibility for all
operation and maintenance failures.
