Chapter 6 Troubleshoot the Switch
Device Manager
Web Interface Issues
These are some basic troubleshooting for issues related to displaying the Device
Manager Web interface.
Issue Resolution
Device Manager Web interface does not display If you cannot display the Device Manager Web interface from your computer or laptop, make sure that you entered the
correct switch IP address in the browser.
If you entered the correct switch IP address in the browser, make sure that the switch and your computer or laptop are in
the same network or subnetwork:
• For example, if your switch IP address is 172.20.20.85 and your computer or laptop IP address is 172.20.20.84, both
devices are in the same network.
• For example, if your switch IP address is 172.20.20.85 and your computer or laptop IP address is 10.0.0.2, the devices
are in different networks and cannot directly communicate without a router. You must either change the switch IP
address or change the computer or laptop IP address.
• If the issue persists, follow the procedure in the
Access Direct Managed Mode section on page 237, and then update
the switch network settings on the device manager Express Setup window.
• If the issue still persists, follow the procedure in the
Recover the Switch Firmware and Restore Factory Defaults section
on page 240.

Recover the Switch Firmware and Restore Factory Defaults section on
page 240.
