CHAPTER 6: Troubleshoting
Problem:
Video appears to be lost after a PC has gone into auto-power-down mode.
Moving the mouse and typing at the keyboard does not wake it up.
Possible Solutions:
This is an example of a simple problem that becomes magnified into bigger
problems: Some computers output an incomplete video signal in auto-power-down
mode. The ServSwitch Wizard Pro can’t “lock on” to such signals and, as a result,
can’t display its on-screen menu. But the Switch’s menu circuitry captures the
keyboard and mouse data anyway, so the computer never gets it and never
“wakes up.” Thus the system appears to “hang.”
To restore the video under these conditions, press [Escape] or [Enter] or
change the CPU channel by typing in your hotkey sequence followed by the
channel number. If you have any PCs in your ServSwitch Wizard Pro system that
tend to do this, you should be careful not to leave your user station idle with the
menu on screen.
Problem:
Compaq MX11800 model integrated keyboard and mouse only:
The mouse consistently
fails to boot when the Switch is connected to PCs running Windows NT 4.0
through their PS/2 style mouse ports.
Possible Solutions:
There are three possible solutions to this problem:
1. Use a different type of mouse.
2. Connect the Switch to your NT 4.0 PCs through adapters and their serial ports
rather than through their PS/2 ports.
3. Select channel 0, or another channel that is not connected to an NT 4.0 PC,
while NT is booting. You should be able to use the system normally once the logon
screen appears.
