METRAL™ backplane pins
Follow the instructions and use the tools provided in the MT370-01 Shelf Level Press-Fit
Repair Kit to straighten METRAL
Guide pins and keying pins
If a stainless steel guide pin or keying pin has been bent out of alignment, attempts to
straighten it may damage the backplane. The recommended alternative is to replace the
bent pin.
D-subminiature pins
The D-Subminiature connectors on the Alcatel-Lucent 1850 TSS-60 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 1850 TSS-60
backplane. Should these jacks be damaged beyond simple repair methods, contact your
next level of support for the replacement procedure.
