Appendix B
Transceivers, Module Connectors, and Cable Specifications
Module Connectors
Figure B-11
RJ-45 Interface Cable Connector
Caution
Category 5e and Category 6 cables can store large levels of static electricity because of the dielectric
properties of the materials used in their construction. Always ground the cables (especially in new cable
runs) to a suitable and safe earth ground before connecting them to the module.
Caution
To comply with GR-1089 intrabuilding, lightning immunity requirements, you must use foil twisted-pair
(FTP) cable that is properly grounded at both ends.
RJ-21 Connector
The RJ-21 connectors (shown in
Figure B-12
) are used on telco modules. Each RJ-21 connector has pins
for 12 ports.
Note
The RJ-21 connector for the WS-X6624-FXS module has pins for 24 ports. See the
“RJ-21 Connector
(WS-X6624-FXS Only)” section on page B-21
.
To connect to 10/100BASE-TX RJ-21 telco interfaces, use Category 5 UTP cables with male RJ-21
connectors, as shown in
Figure B-12
. The WS-X6224-FXS analog interface module also uses an RJ-21
connector, but the pinout arrangement is different than the 10/100BASE-TX.

RJ-45 (both ends)
Warning
If the symbol of suitability with an overlaid cross appears above a port, you must not connect the
port to a public network that follows the European Union standards. Connecting the port to this type
of public network can cause severe personal injury or can damage the unit.
