Interrupt Switch
The hardware interrupt switch is located on the left side of the
bridge/router (when facing the front panel). It is recessed into an
opening near the DIP switches. Press the switch with a nonconductive
object, such as a plastic stylus to put the system into the monitor
firmware utility.
WARNING: Use only a nonconductive object such as a plastic stylus to
press the hardware interrupt switch. Do not use the tip of a pencil.
Graphite particles from the pencil may cause you to receive an electric
shock and damage components on the motherboard.
