When installing terminating resistors, apply the following two rules:
1.
Use only two terminating resistors in any network
2.
Install terminating resistors at the ends (communication and/or
physical) of the trunk line located in the overhead horizontal
wireway.
Incorrect placement of terminating resistors and/or using more than two
will cause improper network operation and result in communication
losses.
