Backplane pin replacement

D-subminiature pins
The D-subminiature connectors on the Alcatel-Lucent 1665 DMX backplane are all of the
receptacle type. These connectors are designated as jacks and not as plugs. The individual
connector terminals are protected somewhat by the molded plastic insert inside the
connector shell. It is unlikely that these terminals would be bent in the manner that the
exposed pin terminals of a plug might be bent. The damage concern for these receptacle
terminals is that they may be "crushed" or otherwise distorted out of shape. Attempts to
"straighten" these terminals may result in fracturing them. If a receptacle terminal has
been damaged to the extent that the mating plug connector cannot be connected, then the
recommended alternative is to replace the entire backplane.
RJ45 jacks
The RJ45 connectors (jacks) are press-fitted into the Alcatel-Lucent 1665 DMX
backplane. Should these jacks be damaged beyond simple repair methods, contact your
next level of support for the replacement procedure.

Replacement methods

Background
Connector pins are designed to withstand a considerable removal force. An impact-type
tool is used to generate a controlled removal force. Similarly, proper insertion of a press-fit
connector pin is done with an impact-type tool to control the insertion forces and not
damage adjacent pins.
Precautions
Read the following Important statements before proceeding:
Note:

plated-through hole may not meet the long-term reliability objectives. If a replacement
is needed for a previously replaced connector pin, contact your next level of support
before proceeding.
