Catalyst 1800 Token Ring Switch Cable Kit Guide

This guide provides configuration and connection instructions for the EIA/TIA-232 console/modem cable and the adapters used when connecting a PC, a VT series terminal, or a modem to the Catalyst 1800TokenRingswitch to access out-of-band management via theEIA/TIA-232 DB-9male console port.
Note EIA/TIA-232 was known as recommended standard RS-232 before 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-ROM package. The Documentation CD-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 Documentation CD-ROM, contact your local sales representative or call customer service. The CD-ROMpackage is availableas a single package or as an annual subscription. Youcan also access Cisco documentation on the World Wide Web at http://www.cisco.com, http://www-china.cisco.com, or http://www-europe.cisco.com.
Management terminal and modem requirements are as follows:
VT 320/420-series terminal or VT-type terminal running emulation programs for the VT series
IBM or compatible PC running a VT-series emulation software package
Hayes-compatible modem
This guide also provides the following pin assignments:
DB-9 console port connector on the Catalyst 1800 chassis
DB-9 PC connector

Connecting to a VT-Series Terminal

DB-25 VT-series connector
DB-25 modem 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-232 cable with RJ-45
connectors at each end
One RJ-45 to DB-9 female adapter (for console port connection)
One RJ-45 to DB-9 female adapter (for PC connection)
One RJ-45 to DB-25 female adapter (for VT terminal connection)
One RJ-45 to DB-25 male adapter (for modem connection)
Connecting to a VT-Series Terminal
Follow these steps to connect a VT 320/420-series terminal to a Catalyst 1800 Token Ring switch (see Figure 1):
Step 1 Plug either end of the EIA/TIA-232 cable intothe RJ-45-to-DB-9 female adapter labelled
“Console port.”
Step 2 Connect the console port female adapter to the male DB-9 console port on the front of the
Catalyst 1800 chassis.
Step 3 Plug the RJ-45 connector at the other end of the EIA/TIA-232 cable into the
RJ-45-to-DB-25 female adapter labelled “VT series.”
Step 4 Connect the VT-series DB-25 female adapter to the DB-25 male adapter on the cable
extending from the VT terminal’s COMM port.
Step 5 Turnon the terminal and access the setup directory. Set the followingparameters 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-band management. Refer to the Catalyst 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-232 cable intothe RJ-45-to-DB-9 female adapter labelled
“Console port.”
Step 2 Connect the console port female adapter to the male DB-9 console port on the front of the
Catalyst 1800 chassis.
Step 3 Plug the RJ-45 connector at the other end of the EIA/TIA-232 cable into the
RJ-45-to-DB-9 female adapter labelled “PC.”
Step 4 Connect the DB-9 female 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-band management. Refer to the Catalyst 1800 Token Ring Switch User Guide for instructions on using the console interface.
