Chapter: Cable and Connector Specifications
Cable and Connector Specifications
This appendix provides the following pinout information:
•
100BaseT Fast Ethernet Specifications
•Console and Auxiliary Port Signals and Pinouts
•Fast Ethernet RJ-45 Connector Pinouts
Note All pins not listed in the tables in this appendix are not connected.
Note Cisco Systems does not provide fast ethernet (FE) port adapter cables. These cables must be ordered from outside commercial cable vendors.
Note Cisco Systems does not provide console and auxiliary cables in the kit. Console and auxiliary cables can be ordered as spares from Cisco Systems.
100BaseT Fast Ethernet Specifications
Each Fast Ethernet port on the MGX-XF-UI back card has an RJ-45 connector to attach to Category 5 UTP for 100BaseTX. Table B-1 lists the cabling specifications for 100-Mbps Fast Ethernet transmission over UTP cables.
1 EIA/TIA-568 or EIA-TIA-568 TSB-36 compliant. 2 Cisco Systems does not supply Category 5 UTP RJ-45 cables. They are available commercially. |
Console and Auxiliary Port Signals and Pinouts
The RPM-XF requires console and auxiliary cables so you can connect a console (an ASCII terminal or PC running terminal emulation software) or modem to your RPM-XF. Cisco Systems does not provide these items. You will need the following items:
•Standard RJ-45-to-RJ-45 rollover cable (see the next section, "Identifying a Rollover Cable" for more information)
•Cable adapters
–RJ-45-to-DB-9 female DTE adapter (labeled Terminal)
–RJ-45-to-DB-25 female DTE adapter (labeled Terminal)
Identifying a Rollover Cable
You can identify a rollover cable by comparing the two modular ends of the cable. Holding the cables side-by-side, with the tab at the back, the wire connected to the pin on the outside of the left plug should be the same color as the wire connected to the pin on the outside of the right plug (see Figure B-1). If your cable was purchased from Cisco Systems, pin 1 will be white on one connector, and pin 8 will be white on the other (a rollover cable reverses pins 1 and 8, 2 and 7, 3 and 6, and 4 and 5).
Figure B-1 Identifying a Rollover Cable
Console Port Signals and Pinouts
Use the thin, flat RJ-45-to-RJ-45 rollover cable and RJ-45-to-DB-9 female DTE adapter (labeled Terminal) to connect the console port to a PC running terminal emulation software. Figure B-2 shows how to connect the console port to a PC. Table B-2 lists the pinouts for the asynchronous serial console port, the RJ-45-to-RJ-45 rollover cable, and the RJ-45-to-DB-9 female DTE adapter (labeled Terminal).

Use the thin, flat RJ-45-to-RJ-45 rollover cable and RJ-45-to-DB-25 female DTE adapter (labeled Terminal) to connect the console port to a terminal. Figure B-3 shows how to connect the console port to a terminal. Table B-3 lists the pinouts for the asynchronous serial console port, the RJ-45-to-RJ-45 rollover cable, and the RJ-45-to-DB-25 female DTE adapter (labeled Terminal).

Auxiliary Port Signals and Pinouts
Use the thin, flat RJ-45-to-RJ-45 rollover cable and RJ-45-to-DB-9 female DTE adapter (labeled Terminal) to connect the auxiliary port to a PC running terminal emulation software. Figure B-2 shows how to connect the auxiliary port to a PC. Table B-2 lists the pinouts for the asynchronous serial auxiliary port, the RJ-45-to-RJ-45 rollover cable, and the RJ-45-to-DB-9 female DTE adapter (labeled Terminal).
Note Connecting to the auxiliary port through a modem is not supported.

Figure B-3 shows how to connect the auxiliary port to a terminal.

Fast Ethernet RJ-45 Connector Pinouts
Table B-6 provides pinouts for the FE RJ-45 connectors.
Note Cisco Systems does not provide FE port adapter cables. These cables must be ordered from commercial cable vendors.

Note Referring to the RJ-45 pinout in Table B-6, proper common-mode line terminations should be used for the unused Category 5, UTP cable pairs 4/5 and 7/8. Common-mode termination reduces the contributions to electromagnetic interference (EMI) and susceptibility to common-mode sources. Wire pairs 4/5 and 7/8 are actively terminated in the RJ-45 port circuitry in the 100BaseTX port circuitry in the FE-TX port adapter.
Depending on your RJ-45 interface cabling requirements, use the pinouts in Figure B-6 and Figure B-7.

SFP Specifications
Table B-7 lists the Small-Form-Factor Pluggable (SFP) module cable specifications that are used with the MGX-1GE Gigabit Ethernet back card. The table lists the SFPs and their respective cable types and lengths.
The MGX-1GE back card provides a trunk uplink that supports 1 Gbps throughput using multimode or single-mode fiber, depending on the connector type. (See Table B-7.)
