Description
This section describes the procedures for the repair/replacement of the press-fit connector
pins used on the backplane of the Alcatel-Lucent 1850 TSS-60 shelf. Trouble clearing
procedures may lead you to inspect the backplane for damaged connectors.
Circuit packs are plugged into METRAL™ signal pin connectors which have been
press-fit into the backplane. A plastic shroud is included with the connectors to protect the
pins. The signal pin press-fit terminals in these connectors my be replaced individually if
they have been damaged beyond simple repair methods.
D-subminiature connectors
Interface cabling to and from the Alcatel-Lucent 1850 TSS-60 shelves is connected
through D-Subminiature connectors which have been press-fit into the backplane. Should
these connectors be damaged beyond simple repair methods, contact your next level of
support for the replacement procedure.
RJ45 jacks
Interface cabling to and from the Alcatel-Lucent 1850 TSS-60 shelves is connected
through RJ45 connectors (jacks) which have been press-fit into the backplane. Should
these jacks be damaged beyond simple repair methods, contact your next level of support
for the replacement procedure.
Shelves and backplanes
The Alcatel-Lucent 1850 TSS-60 has its connectors and terminal identifiers stenciled on
the back surface for identification of location or position. The stenciling can only be seen
when the back cover is removed.
Pins are identified by a column and row position on the backplane. D-Subminiature
connectors are identified by their designation and J-number. All the METRAL™ pins used
on the Alcatel-Lucent 1850 TSS-60 shelves have the same tail length of 4.30 mm (0.169
in.).
