General
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.
5. Can I disable the KVM password ?
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.
7. How many levels of KVM cascade are supported?
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.
FAQ

10. The server VGA resolution does not match the resolution of monitor ?
The KVM supports DDC function which will dynamically detect and the DDC data.
The problem may come from the power on sequence.
- For KVM switch
The recommended power on sequence is - monitor, KVM switch and then servers.
- For remote console box
It supports DDC function but does not support hot-plug, the recommend power on se
quence is – monitor, remote console box and then servers.
Cat5 KVM
Can I use standard Cat5 cable for Cat5 dongle ?
The Cat5 dongle can support Cat5/5e straight cable. To maximum performance and stability, we
strongly recommend applying the Cat5e cable (CU-3 / 6 / 10 / 15 / 33 / 66) from us, we are designed
and qualification tested using pre-made (factory made) Cat5e cable assemblies in fixed lengths.
Using this type of cable assembly will provide excellent link connections and data communication. As
poorly made field cable assemblies can cause damage to the Cat5 KVMs & dongles and result in a
poor or intermittent link. The warranties do not apply to damage resulting from user-supplied cable.
FAQ

1. There is no LED display on KVM membrane switch
i. Make sure the power adapter plugged into the KVM Switch, if the LED’s still off, perform soft
reset to KVM switch.
ii. Power cycle KVM switch.
2. I can power on the KVM, but I am not getting any picture at all, how can I solve this?
Switching to another port and checking if this port has the same problem
a. If you switch to another port, please check the screen resolution is the same.
b. Check the OSD menu is available on the hot keys “Scroll lock + Scroll lock + space bar”.
If the problems persist, please make sure the cables are inserted properly and the boot up
sequence is followed.
3. The screen is on but the keyboard and mouse don’t work
i. Check the server by using a different keyboard and mouse.
ii. For PS/2 servers
The keyboard and mouse are not hot pluggable.
iii. For USB servers
Unplug and plug allowing a few seconds for the bus emulation process to complete.
iv Do not press any keys on the keyboard whilst the server is booting up. This can cause a
keyboard error or cause the keyboard not to detect the KVM switch.
v. Try a different keyboard, but use only 101/102/104-key keyboard
vi. Avoid moving the mouse whilst switching the KVM ports.
4. There is no LED display on the Cat5 dongle
The LED on the Cat5 dongle will flash when plugged into the USB or USB server. The light will then
become steady when the KVM switch has connected. If the LED light is on and not flashing when
plugged into server, please unplug the USB or PS/2 and try again. Or try another good Cat5 dongle
to verify if problem still appears. If the problem persists, please contact your supplier.
