• The switch’s video server may not be functioning properly. First, make sure your account

has the SUPERADMIN privilege. If not, you should request one that has the SUPERADMIN

privilege to do the troubleshooting job for you. Next, go to the Apply Settings screen on the

Web Management interface and click “Restart Servers” to restart the switch. Wait at least 10

more seconds for it to start completely, then try to make the viewer connection again to see

if it is back to normal. Second, If clicking “Restart Servers” doesn’t solve the problem, click

“Emergency Reboot” on the Maintenance screen of the Web Management interface for a

complete start from ground level. An emergency reboot is a clean reboot, and it takes longer

for the switch and video server to load; thus, you need to wait at least a minute for the system

to be up and running. Then try to make the viewer connection again to see if it’s been brought

back to normal. NOTE: A cold boot is always a last resort to bring the switch back: Disconnect

the power adapter from the switch and wait about 30 seconds before plugging it back in and

restarting.
