Troubleshooting
IMPORTANT:
•
The barcode on the router chassis contains product information that must be provided to local
sales agent before you return a faulty router for service.
•
Keep the tamper-proof seal on a mounting screw on the chassis cover intact, and if you want to
open the chassis, contact Hewlett Packard Enterprise for permission. Otherwise, Hewlett
Packard Enterprise shall not be liable for any consequence.
Power supply failure
If the router cannot be powered on and LEDs on the front panel are off, 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 correctly.
3.
Verify that the power source is operating correctly.
4.
Determine if the power cord is damaged.
5.
If the problem persists, contact Hewlett Packard Enterprise Support.
System configuration problems
If the configuration environment setup is correct, the console terminal displays boot information
when the router is powered on. If the setup is incorrect, the console terminal displays nothing or
garbled text.

•

. If the
Data bits
field is set to

or

, the console terminal will display garbled characters.
