Troubleshooting

This appendix provides information for troubleshooting 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.

Power supply failure

Power LED is off

If the router cannot be powered on and the power LED on the front panel is off, it indicates that the
power supply is faulty.
To troubleshoot the power supply:
1.
Power off the router.
2.
Verify that the router's power cords are connected firmly.
3.
Verify that the power source is operating properly.
4.
Determine if the power cord is damaged.
If the problem persists, contact HP Support.

System configuration problems

the router is powered on. If the setup is incorrect, the console terminal displays nothing or garbled text.

steps:
