3.0 Installing Circuit Boards In The Expansion 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 expansion cabinet provides a unique slot for the interface board and universal slots for the auxiliary boards
line boards, or station boards.
This publication provides installation instructions for the interface board. 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 main or expansion common equipment cabinets 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 a 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.
