3.0 Installing Circuit Boards In The Main Cabinet
CAUTION
Circuit boards for the DXP Plus system are susceptible to damage caused by electrostatic discharge, and
you must keep this fact in mind as you handle the circuit boards. Refer to the Comdial publication
IMI01-005, Handling Of Electrostatically Sensitive Components, for general information.
Specific
handling precautions are also included in this installation instruction.
Each circuit board is supplied in a static protection bag. Do not open a static protection bag prior to board
installation time.
The board slots are keyed so that only those boards that will operate from a particular slot will plug into that slot.
The main cabinet provides unique slots for the CPU board, the services board, and the interface board for the main
cabinet). The remaining board slots are universal and will accept auxiliary boards, line boards, or station boards .
This publication provides installation instructions for the CPU and services boards. Since you will install line and
station boards as well as auxiliary boards and other optional circuit boards on an as needed basis, each of these
boards include its own installation instruction for your reference.
3.1
Creating A Static Safe Work Area
When servicing the common equipment cabinet at the installation location, it is a good practice to place a
conductive mat in front of the cabinet area and ground the mat to a good earth ground. (The third wire ground of
the AC power line is also an acceptable grounding point.) The grounded conductive mat provides a safe static
electric discharge path.
When removing the common equipment cabinet from the installation location for servicing, it is a good practice to
prepare a static-safe work area on which to place the cabinet.
You should supply yourself with a static discharge wrist strap, and wear it every time you handle electronic circuit
boards either at the cabinet mounting location or at your work area.
