UNIT 3: INSTALLATION - LESSON 2: INSTALLING OPTIONAL SERVICE CARDS

Opening The Main Unit
A variety of optional service cards can be used to configure the KX-TAW848 Main Unit. The system configuration will ultimately be determined by the end users requirement for CO lines, extension ports and other optional accessories. For the purpose of this lesson, we will install a KX-TAW84880 with a KX-TAW84893, a KX-TAW84876, KX-TAW84861 and KX-TAW84896. This will demonstrate the installation procedure for each available slot type within the Main Unit.

Begin by removing the Main Unit from its carton and stand it upright on a flat work surface.

To open the front cover of the Main Unit, the cable cover must first be removed. To remove the cable cover, pull the slide button on the top of the cable cover to the right and, while holding it, slide the cable cover upwards. Then turn the cable cover slightly to remove it.

Now, lay the Main Unit down with the front cover facing up. Remove the three screws that secure the front cover.

Holding the protrusions on both sides of the front cover, lift the cover open. While the cover is open, be careful not to touch any components on the PCB, and observe electrostatic precautions.
