5.4 Power-On and Checkout
The desktop and rack-mounted versions of the DataTalker differ in how power is applied. The
desktop version has a power switch that you must turn on. The rack version has no power
switch; you apply power by inserting it into a powered-up rack. It is always on as long as the rack
is powered up.
