Catalyst 1800 Token Ring Switch Cable Kit Guide

This guide provides configuration and connection instructions for the EIA/TIA-232console/modem cable and the adapters used when connecting a PC, a VT series terminal, or a modem to the Catalyst 1800 Token Ring switch to accessout-of-bandmanagement via theEIA/TIA-232DB-9male console port.

Note EIA/TIA-232was known as recommended standardRS-232before its acceptance as a standard by the Electronic Industries Association (EIA) and Telecommunications Industry Association (TIA).

Cisco documentation and additional literature are available in a CD-ROMpackage. The DocumentationCD-ROM,a member of the Cisco Connection Family, is updated monthly. Therefore, it might be more up to date than printed documentation. To order copies of the DocumentationCD-ROM,contact your local sales representative or call customer service. TheCD-ROMpackage is available as a single package or as an annual subscription. You can also access Cisco documentation on the World Wide Web at http://www.cisco.com,http://www-china.cisco.com,orhttp://www-europe.cisco.com.

Management terminal and modem requirements are as follows:

•VT 320/420-seriesterminal orVT-typeterminal running emulation programs for the VT series

•IBM or compatible PC running a VT-seriesemulation software package

•Hayes-compatiblemodem

This guide also provides the following pin assignments:

• DB-9console port connector on the Catalyst 1800 chassis

• DB-9PC connector

The Catalyst 1800 console cable kit (part number 78-1188-01)includes

•One 6-foot(1.8-meter)length of unshielded twisted pair (UTP)EIA/TIA-232cable withRJ-45connectors at each end

•One RJ-45toDB-9female adapter (for console port connection)

•One RJ-45toDB-9female adapter (for PC connection)

•One RJ-45toDB-25female adapter (for VT terminal connection)

•One RJ-45toDB-25male adapter (for modem connection)

Connecting to a VT-SeriesTerminal

Follow these steps to connect a VT 320/420-seriesterminal to a Catalyst 1800 Token Ring switch (seeFigure 1):

Step 1 Plug either end of theEIA/TIA-232cable into theRJ-45-to-DB-9female adapter labelled “Console port.”

Step 2 Connect the console port female adapter to the maleDB-9console port on the front of the Catalyst 1800 chassis.

Step 3 Plug theRJ-45connector at the other end of theEIA/TIA-232cable into the

RJ-45-to-DB-25female adapter labelled “VT series.”

Step 4 Connect theVT-seriesDB-25female adapter to theDB-25male adapter on the cable extending from the VT terminal’s COMM port.

Step 5 Turn on the terminal and access the setup directory. Set the following parameters on your terminal:

Transmit	9600
Bits per character (BPC)	8
Parity	None
Stop bit	1
Flow control	Off

After these parameters are set, you can access out-of-bandmanagement. Refer to theCatalyst 1800 Token Ring Switch User Guide for instructions on using the console interface.

Connecting to an IBM PC or Compatible

Follow these steps to connect an IBM PC or compatible to a Catalyst 1800 switch (see Figure 2). Note that the PC must be running a VT terminal emulation program.

Step 1	Plug either end of the EIA/TIA-232cable into theRJ-45-to-DB-9female adapter labelled
	“Console port.”
Step 2	Connect the console port female adapter to the male DB-9console port on the front of the
	Catalyst 1800 chassis.
Step 3	Plug the RJ-45connector at the other end of theEIA/TIA-232cable into the
	RJ-45-to-DB-9female adapter labelled “PC.”
Step 4	Connect the DB-9female adapter to the appropriate male communications port on the
	PC.
Step 5	Turn on the PC and configure its VT emulation package with following parameters:
Transmit		9600
Bits per character (BPC)		8
Parity		None
Stop bit		1
Flow control		Off

After these parameters are set, you can access out-of-bandmanagement. Refer to theCatalyst 1800 Token Ring Switch User Guide for instructions on using the console interface.

Connecting to a Modem

Follow these steps to connect an IBM PC or compatible to a Catalyst 1800 switch (see Figure 3). Note that the PC must be running a VT terminal emulation program.

Step 1	Plug either end of the EIA/TIA-232cable into theRJ-45-to-DB-9female adapter labelled
	“Console port.”
Step 2	Connect the console port female adapter to the male DB-9console port on the front of the
	Catalyst 1800 chassis.
Step 3	Plug the RJ-45connector at the other end of theEIA/TIA-232cable into the
	RJ-45-to-DB-25male adapter labelled “Modem.”
Step 4	Connect the DB-25male adapter to the appropriate female communications port on the
	modem.
Step 5	Turn on the modem and configure its VT emulation package with following parameters:
Transmit		9600
Bits per character (BPC)		8
Parity		None
Stop bit		1
Flow control		Off

After these parameters are set, you can access out-of-bandmanagement. Refer to theCatalyst 1800 Token Ring Switch User Guide for instructions on using the console interface.
