4 USB Ports A USB keyboard and mouse can plug in here. This can either
be in place of, or in addition to, plugging a keyboard and mouse
into the ports on the rear panel. (This port can be used to
connect USB flash storage only on the KN4140v.)
5Reset SwitchNote: This switch is recessed and must be pushed with a small
object such as the end of a paper clip, or a ballpoint pen.
Pressing and releasing this switch when the unit is running
performs a system reset.
Pressing and holding this switch in for more than three
seconds when the unit is running resets its configuration to
the factory default settings.
Note: This does not clear User Account information.
See Clear Login Information, page 226, for
information on clearing user account information.
Pressing and holding this switch while powering on the
switch returns the unit to its factory default firmware level,
rather than the firmware version that the switch has been
upgraded to. This allows you to recover from a failed
firmware upgrade and gives you the opportunity to try
upgrading the firmware again.
Note: This operation should only be performed in the event
of a firmware upgrade failure that results in the device
becoming inoperable.
