Note: The service processor reset button should only be activated as part of a service
action and must therefore be activated very carefully. An insulated paper clip is
recommended. Unbend the clip so that it has a straight section about two inches
long. Insert the clip straight into the hole, keeping the clip perpendicular to the
plastic bezel. When you engage the reset switch, you should feel the detent of
the switch. After you press the switch, the service processor resets and then
shuts down the system.
