Device damage caused by electrical fields or electrostatic discharge
Electrostatic sensitive devices (ESD) are individual components, integrated circuits, modules
or devices that can be damaged by electrostatic fields or electrostatic discharge.
NOTICE
Device damage caused by electrical fields or electrostatic discharge
Electrical fields or electrostatic discharge can cause function failures that result from
damaged individual components, integrated circuits, modules or devices.

Installing a communications processor

Introduction
The communications processors (CPs) are then installed on the R-CPU.
Note
Installing a communications processor in the H-system
For the H-system, you need an active backplane bus to install the communications
processors. You can find more information in the Active backplane bus
