Question about Black Box ServSwitch Jr. (SW622A) KVM Switch

Open Question

Frequent keyboard failure

I have had a problem with my keyboard not working since I switched to this KVM switch. It will work fine for a day or two, then suddenly only about 50% of the keys will work, mostly letter keys with the ctrl key taking on the function of the caps lock key, or the keyboard will not work at all. The mouse still works without any problem. I have tried hitting the reset switch and changing servers on the switch, but the only shutting down the server, then unplugging the cables from the box, then hitting the reset on the Black Box, then powering the server back up will fix the problem, only to have it reappear again within a few days. I am using Dell 2950 PowerEdge servers running Windows 2003 Server with service pack 2. Any suggestions are greatly appreciated.

    I have the same problem. We are using the same kvm switch and the same server. I hope that someone know the reason.

Mac keyboard not working through SV211KDVI on windows

Chances are that the distance between the keyboard & the PC computer is attenuating the signal of the keyboard below the threshold (or level) required for interfacing with the PC computer.

Perhaps a shorter KVM cable between the KVM unit & the PC computer could be helpful.

USB Mouse works, keyboard does not

You will need to update the drivers on the computer for the docking station. It will be the windows seven drivers or lack of them that is causing a failure to remap the usb ports that the wireless dongle is plugged into.

I just bought d-link kvm-221... switching two pc's in a single monitor is working fine but the problem is my keyboard and mouse are not working (didn't detect by kvm-221).

D-Link KVM's have a shortcut for "resetting" keyboard+mouse.

Hold down Scroll Lock and press M

If that does not help, try unplugging mouse and keyboard for 3 seconds then plugging them in again.

Keyboard not working on one side of switch

the GCS632U has keyboard and mouse emulation that may not function correctly with docking stations. To ensure the KVM it self is working correctly I would suggest plugging the single USB from the KVM directly into the laptop and see if you have the same keyboard problem. This will at least tell you if the KVM is working properly or not.

Repeated IOGear KVM switch failures

As a wild guess, it sounds like a static discharge MIGHT be affecting the switcher causing it to crash.

Try increasing your humidity to 40% and grounding yourself before touching the keyboard... This is the season for these static electricity problems... get nipped all the time and you MAY not even feel it to be enough to zap the switch.

KVM freeze, mouse and keyboard failure upon keypress

When ever trouble shooting a KVM that has a problem with one computer always swap the cables at the computer end -- that will tell you if you have a computer or KVM issue.

Can's switch without it switching back to first PC

Sadly, it is probably the KVM as this particular model has a string of failures and is only rated 2 out of 5 stars on Amazon due to poor performance. :( What I would do first is plug in Computer 2 directly to the monitor, keyboard and mouse with no KVM. If those work fine, it is probably not a computer issue; if you don't get video here, then it is a seperate issue with that PC. If Computer 2 is working, plug both computers into the KVM but switch the cables (plug Computer 1 into the KVM using Computer 2's cables). If Computer 2 shows up and can't switch to Computer 1, then it is the KVM messing up.
