Cabling Specifications for the Cisco AccessPath Integrated Access System

This appendix provides selected port and cable assembly pinouts for the Cisco AccessPath Integrated Access System. Further details can be found in the hardware documentation specific to each shelf of the AccessPath system. If you need more information, refer to the documents listed in the table "Related and Referenced Documents" in the chapter "About This Guide."

The appendix includes the following cable assembly and pinout information:

In addition, the appendix includes the following information on cable connections:

Note This appendix specifies pinouts only for the pins used. Pins not listed in the tables in this appendix are not connected.

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



Access Server Shelf Cable Assemblies and Pinouts

Each Access Server Shelf comes with a console cable preconnected to the console port on the Failsafe/Console Management Shelf (these console cables may also be connected to an ASCII terminal or PC running terminal emulation software). An auxiliary cable kit includes cables for connecting to T1 lines and to peripherals such as modems. The Access Server Shelf cable assemblies and pinouts include the following:

For console connections, proceed to the section "Access Server Shelf Console Port Signals and Pinouts" later in this appendix; for modem connections, proceed to the section "Auxiliary Port Signals and Pinouts" later in this appendix.

10BaseT Transceivers

Each of the Access Server Shelves uses a Model BL50 10BaseT IEEE 802.3 Transceiver to connect from its Ethernet LAN port to the Router Shelf. These transceivers should already have been installed before the AccessPath system was shipped. See Figure B-10.


Figure B-10: Model BL50 10BaseT Transceiver



The Failsafe/Console Management Shelf uses a Model BL50R 10BaseT IEEE 802.3 Transceiver. This transceiver should already have been installed before the AccessPath system was shipped. See Figure B-11.


Figure B-11: Model BL50R 10BaseT Transceiver



The 10BaseT transceivers (both models BL50 and BL50R) have four switch settings and seven diagnostic lights. The switches should be kept at the factory settings (shown in Figure B-10), unless changes to the switch settings are recommended by Cisco-certified maintenance personnel.

For information on the factory switch settings, refer to Table B-6.

For information on the diagnostic lights, refer to Table B-7.

For information on pinouts, refer to Table B-8.

Router Shelf Cable Assemblies and Pinouts

Connecting Port Adapter Cables

The instructions for connecting the cables for each port adapter installed in the Cisco 7206 are contained in the respective configuration note for each port adapter. For example, if you are connecting the cables for a Token Ring port adapter, refer the configuration note PA-4R Token Ring Port Adapter Installation and Configuration (Document Number 78-2661-xx). This configuration note accompanies every Token Ring port adapter that is shipped from the factory as an installed item in a Cisco 7206 or as a FRU. The document is also available on the Cisco Connection Documentation, Enterprise Series CD, and on Cisco Connection Online (CCO).

Connecting I/O Controller Cables

The console and auxiliary ports for the Router Shelf are located on the I/O controller. The I/O controller also has an optional Fast Ethernet port (refer to Figure B-12.) This section contains connection equipment and pinout information for the console, auxiliary, and Fast Ethernet ports on the I/O controller.


Figure B-12: Router Shelf I/O Controller Connections



Console and Auxiliary Port Connection Equipment

The I/O controller has two EIA/TIA-232 ports: a DCE-mode console port and a DTE-mode auxiliary port. The console port is a DCE DB-25 receptacle for connecting a data terminal, which you will use to configure the interfaces and bring up the router. The auxiliary port is a DTE DB-25 plug for connecting a modem or other DCE device (such as a CSU/DSU or other router) to the Router Shelf (refer to Figure B-13).

Note Both the console and auxiliary ports are asynchronous serial ports; any devices connected to these ports must be capable of asynchronous transmission. (Asynchronous is the most common type of serial device; for example, most modems are asynchronous devices.)

Before connecting a terminal to the console port, configure the terminal to match the router console port as follows: 9600 baud, 8 data bits, no parity, 1 stop bit (9600 8N1). You need an EIA/TIA-232 DCE console cable to connect the terminal to the console port. After you establish normal router operation, you can disconnect the terminal.

You must supply your own interface cable between the auxiliary port and the equipment you are connecting. For console and auxiliary port pinouts, refer to the following sections "Console Port Signals" and "Auxiliary Port Signals."


Figure B-13: Console and Auxiliary Port Connections



Console Port Signals

Both Data Set Ready (DSR) and Data Carrier Detect (DCD) signals are active when the system is on. 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 B-9 lists the signals used on the console port. The console port requires a straight-through EIA/TIA-232 cable.

1 GND - Ground
2 TxD <-- Transmit Data
3 RxD --> Receive Data
6 DSR --> Data Set Ready (always on)
7 GND - Ground
8 DCD --> Data Carrier Detect (always on)

Auxiliary Port Signals

Table B-10 lists the signals used on the auxiliary port. The auxiliary port supports hardware flow control and modem control.

5 CTS <-- Clear To Send (used for hardware flow control)
6 DSR <-- Data Set Ready
7 Signal Ground - Signal Ground
20 DTR --> Data Terminal Ready (used for modem control only)

Fast Ethernet MII Connection Equipment

The Fast Ethernet port on the I/O controller has a single MII, 40-pin, high-density D-shell type connector that is configurable for 100 megabits per second (Mbps). The MII connector supports IEEE 802.3u interfaces compliant with the 100BASE-X and 100BASE-T standards. The single MII connection requires an external transceiver that permits connection to multimode fiber for 100BaseFX or 100BaseT4 physical media (refer to Figure B-14).

Caution Make sure input power to your Router Shelf is turned off and the router is completely powered down before connecting an external transceiver to the Fast Ethernet port on the I/O controller. If you connect an external transceiver to the Fast Ethernet port when the router is powered on, the system will reset and you could lose data.

Figure B-14: Fast Ethernet Port Connection



Depending on the type of media you use between the MII connection and your switch or hub, the network side of your 100BaseT transceiver should be appropriately equipped with ST-type connectors (for optical fiber), BNC connectors, and so forth.

Figure B-15 shows the pin orientation of the female MII receptacle on the Fast Ethernet port.

The MII receptacle uses 2-56 screw-type locks, called jackscrews, to secure the cable or transceiver to the MII port. MII cables and transceivers have knurled thumbscrews that you fasten to the jackscrews on the MII connector and tighten with your fingers. Use the jackscrews to secure your MII cable to the MII receptacle.

100BaseTX Adapters (Dual Router Shelf Configurations Only)

Each of the Router Shelves in a dual Router Shelf configuration uses a Model BL-6000 MII-to-MII Crossover IEEE 802.3u Adapter to connect from its Fast Ethernet MII port in Slot 0 to the corresponding port on the other Router Shelf.

The female MII connector on the Router Shelves is in an idle state, compliant to IEEE 802.3u, until cables are attached.

The Router Shelf software configuration must contain the following lines:

interface FastEthernet0/0
 !
 full-duplex
 no keepalive

The inclusion of these lines stops the Router Shelf from sending out packets it will expect to see returned, otherwise it will shut down the line.

These transceivers should already have been installed before the AccessPath system was shipped.

The adapters have four diagnostic lights. For information on the diagnostic lights, refer to Table B-12.

The adapters use the pinouts required by the Router Shelf MII receptacle. For information on these pinouts, refer to Table B-11.


Table B-12: Model BL6000 100BaseTX Adapter Diagnostic Lights

Switch Shelf Pinouts

This section lists the pinouts for ports on the supervisor engine module of the AccessPath system Switch Shelf. All pins not specifically listed are not connected. Following is a list of the signal summaries contained in this section:

Switch Shelf DB-25 Console Port Signals

The console port on the supervisor engine module does not support modem control or hardware flow control. Both data set ready (DSR) and data carrier detect (DCD) signals are active when the system is running. The Request To Send (RTS) signal tracks the state of the Clear To Send (CTS) input. Table B-21 lists the signals used on the console port for all supervisor engine module types.

Pin Signal Direction Description
1 GND Ground
2 RxD --> Receive data
3 TxD <-- Transmit data
4 CTS <-- Clear to send
5 RTS --> Return to send
7 GND Ground
8 DTR --> Data terminal ready
20 DCD <-- Data carrier detect

Switch Shelf 40-Pin MII Fast Ethernet Connector Signals

Most Ethernet transceivers require a transceiver cable to connect an Ethernet transceiver to the supervisor engine module Ethernet ports. For descriptions of Ethernet transceivers, connectors, and cables, refer to the section "Connecting the Switch" in the Chapter 3  "Installing the Switch" in the Catalyst 5000 Hardware Installation and Maintenance Guide.

AccessPath System AC Power Cabling

AC power cabling is preconfigured before the AccessPath system is shipped. However, if you add or remove AccessPath system shelves, you will need to refer to the matrix in Table B-29.

Power supplies are connected to specific power receptacles in ways that simplify power connections and preserve redundant power by using different power strips for redundant power supplies.
