RJ-45 Connector
The RJ-45 connector (shown in Figure A-13) is used to connect a Category 3, Category 5, Category 5e, 
or Category 6 foil twisted-pair or unshielded twisted-pair cable from the external network to the module 
interface connector.
Figure A-13 RJ-45 Interface Cable Connector
CautionCategory 5e, Category 6 and Category 6a 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.
CautionTo 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 A-14) are used on telco modules. Each RJ-21 connector has pins 
for 12 ports.
NoteThe 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 A-27.
To connect to 10/100BASE-TX RJ-21 telco interfaces, use Category 5 UTP cables with male RJ-21 
connectors, as shown in Figure A-14. The WS-X6224-FXS analog interface module also uses an RJ-21 
connector, but the pinout arrangement is different than the 10/100BASE-TX.
Figure A-14 RJ-21 Telco Interface Cable Connectors
Ta b l e A - 2 3 lists the output signals for the RJ-21 telco connector. The receive and transmit signals are 
polarized. One pin of each signal pair carries the positive (+) signal, and the other pin carries the negative 
(–) signal.
NoteTa b l e A - 2 3 lists the output signals for the RJ-21 telco connector, not the pinouts of the cable connecting 
to the module.
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.

SC Connector
The SC connector, shown in Figure A-15, is used to connect fiber-optic module ports or transceivers with 
the external SMF or MMF network.
 
WarningInvisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into 
beams or view directly with optical instruments. Statement 1051
NoteMake sure that the optical connectors are clean before making the connections. Contaminated connectors 
can damage the fiber and cause data errors. For information on cleaning the optical connectors, see the 
“Cleaning the Fiber-Optic Connectors” section on page A-38.
Figure A-15 SC Fiber-Optic Connector
Always insert the network connector completely into the socket. A secure connection is especially 
important when you are establishing a connection between a module and a long distance (1.24 miles) 
(2 km) network or a module and a suspected highly attenuated network. If the link LED does not light, 
try removing the network cable plug and reinserting it firmly into the module socket. It is possible that 
dirt or skin oils have accumulated on the plug faceplate (around the optical-fiber openings), generating 
significant attenuation and reducing the optical power levels below threshold levels so that a link cannot 
be made. 
CautionUse extreme care when removing or installing connectors so that you do not damage the connector 
housing or scratch the end-face surface of the fiber. Always install protective covers on unused or 
disconnected components to prevent contamination. Always clean fiber connectors before installing 
them.

MT-RJ Connector
The MT-RJ connector is a small form-factor fiber-optic connector used to connect modules to a SMF or 
MMF optical network. (See Figure A-16.) The small size of the MT-RJ connector, as compared with the 
SC connector, allows for a greater port density on the modules. The MT-RJ connector is a two-fiber 
connector (transmit and receive) and has a form factor and clip lock retainer similar to the RJ-45 copper 
connector.
WarningInvisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into 
beams or view directly with optical instruments. Statement 1051
NoteMake sure that the optical connectors are clean before making the connections. Contaminated connectors 
can damage the fiber and cause data errors. For information on cleaning the optical connectors, see the 
“Cleaning the Fiber-Optic Connectors” section on page A-38.

LC Connector
WarningInvisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into 
beams or view directly with optical instruments. Statement 1051
The LC fiber optic connector, shown in Figure A-17, is a small form-factor fiber-optic connector that 
provides high-density fiber connectivity. The LC connector can be used with either MMF cable or SMF 
cable. The LC connector uses a latching clip mechanism that is similar to the one used on the RJ-45 
copper connector.
NoteMake sure that the optical connectors are clean before making the connections. Contaminated connectors 
can damage the fiber and cause data errors. For information on cleaning the optical connectors, see the 
“Cleaning the Fiber-Optic Connectors” section on page A-38.

Figure A-19 Twisted-Pair Crossover 1000BASE-T Cable Schematic
NotePower over Ethernet (PoE), uses pairs 2 and 3 (pins 1, 2, 3, and 6) in a four-pair UTP cable to transmit 
power from the switch to a powered device. This method of supplying power is sometimes called 
“phantom power” because the PoE power travels over the same pairs of wires used to transmit the 
Ethernet signals. The PoE voltage is completely transparent to the Ethernet signals and does not interfere 
with their operation.
Catalyst 6500 series switches come with an accessory kit that contains the cable and adapters that you 
will need to connect a console (an ASCII terminal or PC running terminal emulation software) or modem 
to the console port. The accessory kit includes these items:
RJ-45-to-RJ-45 rollover cable
RJ-45-to-DB-9 female DTE adapter (labeled “Terminal”)
RJ-45-to-DB-25 female DTE adapter (labeled “Terminal”)
RJ-45-to-DB-25 male DCE adapter (labeled “Modem”)
