KVM Switch KVM2132P, KVM2116P, KVM1116P User Manual 114
Troubleshooting
General Operation
Problem Resolution
Erratic Operation Start the KVM switch before any tiered switches.
1. Power it on before powering on tiered switches.
2. If the tiered switch was started before the KVM switch, reset or restart
the tiered switch.
Press and release the Reset switch (see “Reset Switch” on page 7).
I have been given an account but I am unable
to log in.
1. Make sure your Username and Password are correctly specified.
2. Make sure that you have the necessary permission to access the switch.
3. Ask if the switch is under KVM Access management. If it is, the
administrator will have to disable KVM Access management on the
switch (page 70), or deselect it on the KVM Access server (see the KVM
Access User Manual for details).
I can't access the switch, even though I have
specified the IP address and port number
correctly.
If the switch is behind a router, the router's Port Forwarding (also referred
to as Virtual Server) feature must be configured. See “Port Forwarding”
on page 106 for details.
When logging in from a browser, the
following message appears: 404 Object Not
Found.
If a login string has been set, make sure to include the forward slash and
correct login string when you specify the KVM switch's IP address. (See
“Login String” on page 76.)
Sudden loss of network connection. Close your connection to the KVM switch. Wait about 30 seconds, and
log in again.
No remote server video display on the client
computer.
Check that your KVM Adapter Cable's firmware version is the same as
the version stored in the switch's Main firmware. See “Adapter Firmware
Upgrade” on page 92 for details. Set the remote server resolution to 1280
x 1024 or less.
No remote server video display on the client
computer, but mouse movements appear on
the local console and mouse clicks have no
effect
Press and release the left Alt key, then press and release the right Alt key
The display on the client computer is distorted
and performing an Autosync doesn't resolve
the problem.
Switch ports to a port with a different resolution, then switch back. If that
does not resolve the problem, change the resolution and refresh rate for
the system running on the port. Afterward, you can run at the new
resolution, or switch back to the original resolution.
The Lock Key LEDs on the Control Panel
don't accurately reflect the actual locked status
of my keyboard input.
Click the LEDs on the Control Panel until they match your keyboard.
Afterward, when you change them from the keyboard they will change on
the Control Panel.
When I log in, the browser generates a CA
Root certificate is not trusted, or a Certificate
Error response.
The certificate's name is not found on Microsoft's list of Trusted
Authorities. The certificate can be trusted. See “Trusted Certificates” on
page 112 for more information.
In multiuser operation I had exclusive (or
occupy) rights on the port I was viewing. After
I recalled the Port Access page and came back
to the port I was occupying, it had been taken
over by another user. Why did this happen?
If you try to return to the port by selecting again in the tree, the switch acts
as if you are accessing the port for the first time. If another user was
waiting on the port, he takes precedence and gets the port. The correct
way to return to the port is to click the Close icon at the top right of the
Port Access page.
