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.

Table 5-3. Power-On and Checkout Procedure

Step Procedure

1Desktop version: Ensure that the power supply is connected to the unit’s power connector and an AC outlet.

Rack version: Ensure that the DataTalker is properly seated in a RackTalker rack. Tighten the front panel screws to ensure a good connection with the RackTalker power bus.

2Desktop version: Apply power (press the power switch on the back of the unit to I [on]).

Rack version: Plug the RackTalker rack into an AC outlet, if it is not already powered up.
