1. How do the KVM switches allow the user to switch ports?
There are two ways to switch ports. One is the membrane buttons on the front and the other way is
with Hot-key commands.
2. What operating systems do the KVMs support?
The KVMs support multi-platform support allows you to control Windows-based computers, Sun So-
laris systems, Linux, or even Macs by a single KVM switch. The KVM switches support multi-platform
operating systems including but not limited to DOS, Windows 95/98/ME/NT/2000/XP, Linux, Solaris
and Mac OS.
3. Do I have to power down the KVMs to add a new server ?
The KVMs are hot-pluggable and allows servers or devices to be added or removed without power-
ing down the switch, but components of connected devices, such as the servers, may not be hot-
pluggable. We suggest that turn off power to all devices before connecting them.
4. Why I can’t login with default password on KVM switch
The default username and password for the KVM switch is eight zeros - “00000000”. Please check
i. The “Num lock” is not turned on. (for notebook type keyboard)
ii. The numeric (number) keys on the number pad are not accepted by KVM, only the main
number keys.

Yes, for Cat5 KVM, USB KVM, two console PS/2 KVM & IP PS/2 KVM, user can disable/ enable the
KVM password by hotkey.
No, for PS/2 KVM, user can’t disable the KVM password.
6. What do I do if I forget the password?
If the user change the default password and lose the password, pls contact the supplier for further
support.

8 levels are supported.
8. Can I cascade the different types KVM switches together ?
No, only same type KVM can cascade together. (e.g. PS/2 to PS/2, USB to USB,..)
9. Why am I getting ghosting images or shadowing?
i. Check that all video cables are inserted properly.
ii. Check whether the KVM supports the resolution and refresh-rate on your servers.
iii. Check whether the graphics card you are using supports the resolution and refreshrate on
your server or not.
iv. Connect the monitor directly into the servers you are having trouble with to see if problem
still appears.
