HP MSR2000 Router Series Installation Guide

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 mountin

screw on the chassis cover intact, and if you want to open the

chassis, contact HP for permission. Otherwise, HP shall not be liable for any consequence.

3. Verify that the power source is operating correctly.

Solution

1. Verify that the fans are in position.

Troubleshooting the configuration system failures

If the router operates properly after being powered on, the boot information is displayed on the

configuration terminal. If the configuration system is faulty, the configuration terminal displays garbled

characters or does not display anything.
