5.11 Performing a Warm Reset
Sometimes, when problems occur in a ServSwitch Wizard MP system, powering the
Wizard MP off and back on again can fix the problem. If a Wizard MP is getting
power from its optional power supply, you can do this by unplugging and
replugging the power supply. But if the Wizard MP is getting power from the
attached computers, the only way to shut it down is to disconnect it from those
computers or turn the computers off, which might not be desirable or possible.
Instead of powering the Wizard MP off and back on to completely reinitialize it,
you can accomplish the same results by having the Wizard MP do a “warm reset”
(hardware reset) while it’s still operating. You’ll see a small hole on the bottom of
the Wizard MP; this hole has a recessed switch in it. Use a paperclip, the tip of a
pen or pencil, etc., to press this switch and trigger a warm reset.
Even though the Wizard MP doesn’t have any CPU startup communication to
work with after a warm reset, it should still be able to autodetect the correct
keyboard mode and mouse type under most circumstances. Occasionally, however,
you’ll also need to do a mouse reset and/or recovery (see
Sections 5.8
and
5.9
) to
get the mouse working properly.
