Fiber Optic redundancy

Series 8 links are redundant; FOE modules are always installed in pairs for possible link
A and B connections. Therefore, two independent fiber cables (one for Link A and one
for Link B) are required between each local and remote connection.
9.2 FOE Installation
The procedures in this guide assume that you have completed all pertinent planning
activities as outlined in the Control Hardware Planning Guide.

Handling components - ESD

Electrostatic discharge can damage integrated circuits or semiconductors if you touch the
connector pins.
