Cabling Specifications and Compliance Information

This appendix lists the port pinouts on the supervisor engines and the standards compliance specifications.

Note   Any pin not specifically listed is not connected.

Supervisor Engines I and II Console Port

The console port on Supervisor Engines I and II is an EIA/TIA-232, data communications equipment (DCE), DB-25 receptacle. Both data set ready (DSR) and data carrier detect (DCD) are active when the system is running. The Request To Send (RTS) signal tracks the state of the Clear To Send (CTS) input. The console port does not support modem control or hardware flow control. Table A-1 lists the Supervisor Engine I and II console port pinouts.

Supervisor Engine III Console and AUX Ports

Note   The Supervisor Engine III auxiliary (AUX) port is currently not supported.

You can connect the Supervisor Engine III console port to an ASCII terminal or PC running terminal emulation software. Table A-2 lists the pinouts for the asynchronous serial console port. In addition to the RJ-45-to-RJ-45 cable provided in the console port accessory kit (shipped with your Catalyst 5000 family switch), you will need either an RJ-45-to-DB-9, RJ-45-to-D-subminiature female, or RJ-45-to-D-subminiature male adapter (these adapters are provided in the accessory kit).

Supervisor Engine II G and III G Console Ports and RSFC Console Ports

You can connect the Supervisor Engine II G or III G console port to an ASCII terminal or PC running terminal emulation software (console port) or IOS software (RSFC console port). Table A-3 lists the pinouts for the asynchronous serial console port. Table A-4 lists the pinouts for the RSFC console port.

In addition to the RJ-45-to-RJ-45 cable provided in the console port accessory kit (shipped with your Catalyst 5000 family switch), you will need either an RJ-45-to-DB-9, RJ-45-to-D-subminiature female, or RJ-45-to-D-subminiature male adapter (these adapters are provided in the accessory kit).

Supervisor Engine Interface Ports

This section describes the supervisor engine 100BASE-TX, 100BASE-FX, 1000BASE-SX, and 1000BASE-LX/LH interface ports.

100BASE-TX Cabling Specifications

Table A-5 lists the cabling specifications for the 100-Mbps uplink modules.

100BASE-TX Ports

This section lists the supervisor engine 100BASE-TX port pinouts.

40-Pin MII Ports

Table A-6 lists the pinouts for the 40-pin MII Fast Ethernet ports.

RJ-45 MDIX Ports

Table A-7 lists the pinouts for the RJ-45 MDIX Fast Ethernet ports.

100BASE-FX, 1000BASE-SX, and 1000BASE-LX/LH Ports (SC Fiber-Optic Connectors)

Use SC fiber-optic connectors (see Figure A-1) to connect to the 100BASE-FX (two port), 1000BASE-SX, and 1000BASE-LX/LH ports. Use MT-RJ fiber-optic connectors (see Figure A-2) to connect to 100BASE-FX (four port) ports. Always keep caps and plugs on the fiber-optic connectors on the cable and the switch when they are not in use.

Cabling Considerations for GBICs

The Gigabit Interface Converter (GBIC) is a hot-swappable input/output device that plugs into a Gigabit Ethernet or EtherChannel module, linking the module with the fiber-optic network. For more information on GBICs, see the "Connecting Gigabit Ethernet Modules" section.

Table A-8 provides cabling specifications for the GBICs that you install in the Gigabit Ethernet module. Note that all GBIC ports have SC-type connectors, and the minimum cable distance for all GBICs listed (multimode fiber [MMF] and single-mode fiber [SMF]) is 6.5 feet (2 m). The minimum cabling distance for the ZX GBIC is 6.2 miles (10 km) with 8-dB attentuators installed at both ends of the link and 24.9 miles (40 km) without attenuators.

1MMF only. 2Mode-conditioning patch cord (CAB-GELX-625 or equivalent) is required. Using an ordinary patch cord with MMF, 1000BASE-LX/LH GBICs, and a short link distance (less than 100 meters) can cause transceiver saturation resulting in an elevated bit error rate (BER). In addition, when using the LX/LH GBIC with 62.5-micron diameter MMF, you must install a mode-conditioning patch cord between the GBIC and the MMF cable on both the transmit and receive ends of the link. The mode-conditioning patch cord is required for link distances greater than 984 ft (300 m). For link distances less than 300 m, a patch cord is not required. 3A maximum of 12 ZX GBICs are supported in a switch chassis. 4Dispersion-shifted single-mode fiber-optic.

Note   The mode-conditioning patch cord (CAB-GELX-625 or equivalent) is required to comply with IEEE standards. The IEEE found that link distances could not be met with certain types of fiber-optic cable cores. The solution is to launch light from the laser at a precise offset from the center by using the mode-conditioning patch cord. At the output of the patch cord, the LX/LH GBIC is compliant with the IEEE 802.3z standard for 1000BASE-LX. For more information, see the "Patch Cord (1000BASE-LX/LH Uplink Port Only)" section.
