Introduction
WARNING
The procedures in this section are
intended only for qualified ser-
vice personnel. Do not perform
these procedures unless qualifie
to do so. Failure to recognize and
observe normal safety precau-
tions could result in personal
injury or death.
The information in this section is arranged as follows:
•
Handling precautions
Explains precautions
that must be followed to prevent contamination to the
switch card. Contamination could degrade the perfor-
mance of the card.
•
Multi-pin (mass termination) connections
Covers the basics for connecting external circuitry to
the connector card.
•
Model 7036 installation and removal
Pro-
vides the procedures to install and remove the Model
7036 switch card from the Model 7001/7002 main-
frame.
Handling precautions
To maintain high impedance isolation, care should be taken
when handling the card to avoid contamination from such for-
eign materials as body oils. Such contamination can substan-
tially lower leakage resistances and degrade performance.
To avoid possible contamination, always grasp the relay card
and the connector card by the side edges or shields. Do not
touch the board surfaces or components. On connectors, do
not touch areas adjacent to the electrical contacts. Dirt
buildup over a period of time is another possible source of
contamination. To avoid this problem, operate the mainframe
and switch card in a clean environment.
