SERVSWITCH™ BRAND CAT5 KVM MICRO EXTENDER

Connecting a keyboard to the Remote Unit has an adverse effect on the remote video.

Try using a newer keyboard. (Some older keyboards require too high a current for

the Remote Unit to properly drive the video signal.)

I’m not using a keyboard, but the Extender doesn’t work at all.

See Section 8.1.7.

8.1.2 M

OUSE

There is a mouse cursor/pointer on the screen, but the mouse does not work.

1. Reset the keyboard and mouse as described in Section 7.3.1.

2. Check the mouse cable and (if necessary) the mouse portion of the extension

cabling to your CPU or KVM switch; if it’s loose, or if you have the keyboard

and mouse cables reversed (plugged into each other’s Micro Extender ports),

plug the cable(s) in properly and reset the keyboard and mouse as described

in Section 7.3.1.

3. If the PC is a Pentium class machine, see the entry for the “Pentium class

PC...” problem in Section 8.1.3.

4. Check the interconnect cable between the Micro Extender’s Local and

Remote Units. Is it solid-core cable? Is it intact along its length and securely

connected at both ends? And is it wired correctly? (Compare its wiring with

that shown in the Appendix A.)

5. Try powering the Remote Unit OFF and then ON again.

6. Try using a different model of mouse.

7. Do any inputs work at this point? If not, reboot the PC.

The PC does not detect a PS/2 mouse, or the application cannot find the mouse.

1. Check the mouse cable and (if necessary) the mouse portion of the extension

cabling to your CPU or KVM switch; if it’s loose, or if you have the keyboard

and mouse cables reversed (plugged into each other’s Micro Extender ports),

plug the cable(s) in properly and reset the keyboard and mouse as described

in Section 7.3.1.

2. Make sure that the cable running from the keyboard port of the CPU or KVM

switch to the Micro Extender’s Local Unit is intact and securely attached, so

that it provides power to the Local Unit.

3. If the PC is a Pentium class machine, see the entry for the “Pentium class

PC...” problem in Section 8.1.3.

4. Reboot the PC.
