ACCESSING THE RELEASE NOTES
The Release Notes provide release highlights and important information related to this release that
should be reviewed before you begin the system’s installation and configuration.
The Release Notes are located on the CD as well as on the system’s FLASH file system.
The Release Notes on the CD are located in the REL_NOTE.TXT file. This file is a DOS text file you
can read on a DOS machine. Insert the CD into the drive, change to the proper directory, and enter
the following command at the DOS prompt:
[CD-ROM drive]:\[platform directory][ISDN standard directory][option directory]CSX1200>
type REL_NOTE.TXT | more
For example, if your CD-ROM is designated as drive D, you are installing is CSX1204, using US
ISDN standards and the IP/IPX option, you would use the following path:
D:\CSX1204\US\IPIPX> type REL_NOTE.TXT | more
ACCESSING THE CYBERSWITCH
There are two ways to access the system. The first method uses a console connection through the
console port on the back of the system, and connects up either a terminal or a workstation/PC
executing a terminal emulation program. The second method is to Telnet to the system. We
describe each of these methods below.
CONNECTING AN ADMINISTRATION CONSOLE
There are two ways to set up a console connection. The first way is to simply connect up an ASCII
terminal to the console port on the back of the system. This method can only be used to configure
or manage the system. To install or upgrade system software, you must use the second method
described below.
The second way is to use a PC or workstation to connect to the system. The CyberSWITCH does
not have a CD-ROM drive. Therefore, you must upgrade or install the software through an
attached PC, UNIX workstation, or any device that meets the following requirements:
• has a CD-ROM drive
• provides an RS232 terminal program
• has X-Modem communications capability (required for software upgrade only)
• has ASCII transfer capability (required for SSB recovery)
Any computer or terminal that meets these requirements and connects to the administration port
on the system can operate as an administration console.
Using the provided RS232 null modem cable, attach an administration console to the system. The
administration port is a 9-pin, male RS232 serial adapter:

Workgroup Remote Access Switch 9
B ASICS
Accessing the CyberSWITCH
Connect one end of a null modem cable to the console port on the CyberSWITCH, and the other
end to the communication port on the PC. On the PC you must then execute a communication
package to emulate a terminal (VT100). Your communication package should support file transfer
(Xmodem and ASCII) for software upgrades and installations.
Use the following default values for your communication package:
Baud rate 9600
Parity None
Data bits 8
Stop bits 1
Duplex Full
CHANGING THE BAUD RATE
The baudrate is changeable. The default rate performs well for configuration changes. A faster rate
is useful, however, to download new software upgrades to your system.
To change the baud rate through CFGEDIT:
1. Select Physical Resources from the main menu.
2. Select Data Line from the physical resources menu.
3. Follow the instructions to make changes to the ASYNCMDM.
4. When asked, enter the baud rate you want to use.
5. Step through the remaining parameters. The last entry will ask you if you would like to save
your changes. Answer yes.
6. To make the new baud rate effective, restart the system (with the
restart command).
7. Change the communications package you are using to the same baud rate.
To change the baud rate using Manage Mode:
1. Enter the Manage Mode by entering the following command:
>

3. Follow the on-screen instructions for changing the baud rate.
TELNET CONNECTION
You can access the CyberSWITCH with Telnet. To do this, you must use Telnet client software.The
CyberSWITCH has default IP addresses configured to allow Telnet access. The default LAN IP
address is 1.1.1.1. To access the CyberSWITCH you must set the device’s IP address to be on the
same subnet as the CyberSWITCH. We recommend that you use 1.1.1.2 and do this on a LAN that
is not connected to the internet. Then place the CyberSWITCH on the LAN and Telnet to the
address.
This default address allows immediate access to the system for installation purposes. Be sure to
change this IP address as soon as possible to one on your local subnet.
Note: Do NOT place more than one CyberSWITCH on a LANwiththe default setting. With both
having the same IP address, unpredictable results will occur.
You may also Telnet in via the WAN connection. The general procedures are:
1. Connect the system to the (WAN) ISDN line.
2. From a remote device that supports UnNumbered IP connections, dial in as a PPP CHAP
device USER1 (USER1 as secret). The address on the CyberSWITCH to Telnet to is 1.1.1.1.
3. From a remote device only supporting numbered IP connections, set up an IP Address 2.2.2.3
and have it dial as a PPP CHAP device USER2 (USER2 as secret). The address on the
CyberSWITCH to Telnet to is 2.2.2.2.
After you make a Telnet connection, enter your login id and password. Then you will be presented
with a system prompt and you can enter commands at that time.
LOGIN ON THE CYBERSWITCH
Once you have a connection to the CyberSWITCH, you will be presented with a prompt to enter
your log in id. Use admin as the login id. You will then be prompted for a new password, so choose
a password that you will remember. If your software was previously accessed by your distributor,
your password will be admin (in lower case).
After you have logged in, you many enter any command at the system prompt.
MAKING CONFIGURATION CHANGES
We provide two configuration tools to set up and/or alter your configuration. These tools are:
• CFGEDIT, the full configuration utility
• Manage Mode, the dynamic management utility

Workgroup Remote Access Switch 11
B ASICS
Upgrading Software
The CyberSWITCH is configured using the configuration editor, CFGEDIT. To begin the
configuration process:
Start up the configuration editor, CFGEDIT. Your machine should beat the system prompt.To start
up the configuration editor simply type:
[system name]>
cfgedit
The main configuration menu should now be displayed. Refer to Connectivity for the configuration
steps required for the device you wish to connect.
Note: If you are prompted for configuration information that you don’t know, use the default.
This document will provide detailed instructions if something other than the default is
required.
Once the system is working, minor configuration changes can be made in real time with the
Dynamic Management feature. This feature consists of console commands that enable you to
display current system parameters, change many parameters dynamically, and write changes to
disk files so that they remain permanent. Before usingDynamicManagement commands, youmust
first enter the special Manage Mode by typing the following command at the system prompt:
>manage
While operating in Manage Mode, only Dynamic Management commands are available. All other
system commands are ignored until you exit Manage Mode.
UPGRADING SOFTWARE
An upgrade of system software may involvethe upgrade oftwo components:the second stage boot
(SSB) and the operational software (OSW). For most upgrades, if you have a working SSB, you will
only need to upgrade the OSW. If the new OSW requires an upgraded SSB, you will be alerted in
the Release Notes.
The CyberSWITCH offers two different methods of upgrade—local and remote.
• To perform a local upgrade refer to the section titled Local Software Upgrade. (A local upgrade
is performed via the administration console attached to the system’s RS232 port).
• To perform a remote upgrade refer to the section titled Remote Software Upgrade. (A remote up-
grade is performed over the network using Telnet and TFTP).
For countries other than Japan, upgrade files are located on the CSX1200 CD. Refer to the immedi-
ately following section for CD file structure information.
For Japan, refer to the CSX1200 CD for documentation only. Note that Japanese upgrade files are
provided on diskettes. Keep this in mind while reading through the following file structure and
upgrade instructions.

QUICK START
12 CyberSWITCH
CD FILE STRUCTURE
TheCSX1200CDcontainsinstallation, user documentation and upgradefiles. The CD file structure
is as follows:
For system upgrade, you will need to follow a specific upgrade path (\product name\country or
switchtype\protocol or access package). This path not only depends upon product, but also the ISDN
Standard you will be using, the software options you have purchased, and in many cases, the
switch type. For example:
• If you are installing a CSX1223 in a geographical area that uses US ISDN standards, and you
have purchased the IP/IPX software option, use the files found in the \CSX1223\US\ipipx di-
rectory.
• If you are installing a CSX1204 using a NET3 international switch, and have purchased the IP,
IPX, AppleTalk and Frame Relay options, use the files found in the \CSX1204\intnet3\ipipx-
at.fr directory.
Refer to the Upgrading System Software section of the User’s Guide for a listing of possible upgrade
path directories.
LOCAL SOFTWARE UPGRADE
To perform a local upgrade, use any valid local administration console as defined in Connecting an
AdministrationConsole. Update the SSB first, if the Release Notes indicate this is necessary, and then
follow with the update of the OSW.
LOCAL UPGRADE OF THE SECOND STAGE BOOT (SSB)
To locally upgrade the second stage boot (SSB), follow these steps:
1. Restart the CyberSWITCH.
2. When “Waiting for Commands:” appears on the system screen, enter the following command:
recover
3. Wait for the system to respond with the prompt “Ready for Hex Download”. Using your
communications program:
• Select ASCII to be the protocol used for the file transfer.
• Change character spacing to “0”. (This may be called by another name in some
communications packages. For example, some programs call it character pacing.)
• Set line spacing (or pacing) to “0”.
• insert the CSX CD into the CD drive of your administration console.

automatically reboot.
LOCAL UPGRADE OF THE OPERATIONAL SOFTWARE (OSW)
To locally upgrade the operational software (OSW) of your system, follow these steps:
1. Change the CyberSWITCH system’s baud rate to be the fastest baud rate supported by your
communications package (up to 115.2 Kbps). Change the baud rate as described on page 9.
2. Login to the CyberSWITCH as admin.
3. At the system prompt, enter the command:
flash update
This message is displayed:
4. At this time you should press “Y” <RET>. After 30 seconds, you will see the startup messages.
5. When it displays the download message, “Ready for Xmodem Download,” return to your
communication program and use the “XMODEM” protocol for the software download.
6. Enter the name of the file that is to be downloaded, using the complete pathname. Forexample,
D:\CSX1204\US\IPIPX\UPGRADE.OSW.
Note: Your terminal program may display a character for the NAKcontrol code, typically the
character “§“. This will be displayed every second until the download has started.
7. After the file has been downloaded, the system will reboot automatically and load using the
new software.
REMOTE SOFTWARE UPGRADE
Note: For security purposes, we recommend that you disable the TFTP Server after the upgrade
is complete.
The following remote upgrade procedure is supported for version 1.1.1 or newer of the Second
Stage Boot (SSB), and software release 1.2 or greater of the Operational Software (OSW). If you are
unsure of the version of software currently running on your CyberSWITCH, issue the
ver
command to display this information.
To remotely upgrade the system, you are required to have a PC/workstation that is connected to
the system’s network. It must have the following features:
• ability to read CDs
>flash update
WARNING: You are about to restart the system.
You should allow 30 seconds before a system restart occurs.
Do you still wish to restart (Y or N)?

QUICK START
14 CyberSWITCH
• TELNET client
• TFTP client
To perform a remote upgrade, first upgrade to the latest SSB, if required, then upgrade the OSW.
The Release Notes will indicate whether or not the SSB needs to be upgraded.
Note: If,during a remote upgrade,the compressed fileset cannot be uncompressed into the Flash
File System due to a lack of space, the compressed file set will not be deleted from the Flash
File System and the previous version of the OSW will be booted. If the OSW determines
there is a compressed file set (a file suffix of .OSW) in the Flash File System, then the
following message is logged in the system log:
OSW, <OSWFileName>, found in the Flash File System. The OSW has not been
updated from this file due to insufficient Flash File System space.
Please delete unnecessary files from the system.
It is possible that you will not have enough room in the \SYSTEM directory to TFTP the
upgrade file to the system. In this case:
• Delete all files in the directory except nex.bin and iop.bin.
•Issuea
flash reclaim command to gain the lost space (thiswill destroy the backup
copy of your configuration, you will be unable to issue restore command unless you
have saved at least one set of changes).
• If the upgrade still fails, delete the nex.binand iop.binand again reclaimthe space.
Your upgrade should nowwork.IMPORTANT:Do not restartthe CyberSWITCH until
the upgrade is complete.
If you are upgrading from a previous version of system software, the above message will
notbe displayed. In this case, thesystem continually restarts, attempting to install theOSW
package each time.
REMOTE UPGRADE OF THE SECOND STAGE BOOT (SSB)
WARNING:
If power is lost on the remote CyberSWITCH during this process, a local upgrade of the
SSB may be necessary before the system can again function.
To remotely upgrade the SSB, follow these steps:
1. Telnet to the CyberSWITCH and login as admin.
2. Enable TFTP, the TFTP client, and the TFTP server with admin access rights (see page 15.)
3. Using the TFTP client on the remote workstation, TFTP the recover1 file to the
CyberSWITCH in binary mode. Be sure to use the file’s full pathname. The exact method to
transfer varies, depending upon your TFTP client.
4. At the system prompt, recover the SSB by issuing the following command:

Note: If you experience a transmission timeout, check the retransmission setting on the TFTP
package. A retransmission rate of 10 seconds is usually sufficient; values less than that
may not work properly.
If you experience a problem transferring the file with TFTP, wait about three minutes
for the TFTP to fail, delete the incomplete file, and try again.
4. Using Telnet, reboot the system by issuing the command:
restart
It should take approximately 3 minutes for the system to restart and install the upgrade.
5. Login via Telnet and type the
ver command to confirm that the system software upgraded
correctly. If the upgrade did not occur, check the system log with the
dr command to find any
potential problems, and retry.
CHANGE DEFAULTS TO SECURE SYSTEM
The system is preconfigured with defaults that were designed to make it possible to have your
system up and running quickly. After your machine is functioning properly, some of these defaults
should be changed to make your system more secure. The following configuration changes are
needed to provide this security:
1. Either delete User1 and User2 or change their names and secrets.
Use Dynamic Management’s manage mode to carry out either of these functions. To enter the
manage mode, type
manage at the system prompt. If you have no need for these types of
devices (PPPdevices), simply delete these two devices. At the manage mode prompt, enter the
following command:
device delete
Follow the on-screen instructions for deleting each device.
To change the preconfigured devices’ names and secrets to secure the access to the system,
enter the following command at the manage mode prompt:
device change
Follow the prompts to change the device name and secret for User1 and User2. After you have
either deleted or changed the device information, make these changes permanent by entering
the
commit command
2. Disable TFTP Server.
Disable through Dynamic Management’s manage mode. This will secure important device
information. Device information must be secure to prevent unauthorized access to the
CyberSWITCH. To disable this access, enter the following command at the manage mode
prompt:
tftp change
Then follow the on-screen instructions to disable the TFTP feature.
3. Change the admin and guest system passwords.

Workgroup Remote Access Switch 17
B ASICS
Return Configuration to Factory Defaults
If your system was previously accessed by your distributor, the preconfigured password will
be admin (in lower case). Change this password to secure your system. To make this change,
enter the following command at the system prompt:
pswd
Then follow the prompts to enter a new password. Your password must be a 3 to 16 nonblank
character string. Be careful, passwords are uppercase and lowercase sensitive.
RETURN CONFIGURATION TO FACTORY DEFAULTS
The default configuration files are located on the CSX1200 CD. If you wish to return to the default
configuration, download the DEFLTCFG.OSW file. Follow the same steps for Local or Remote
Upgrade except you download the file DEFLTCFG.OSW instead of the UPGRADE.OSW file.
INITIAL INSTALLATION STEPS
There are initial configuration steps you must complete (regardless of remote device connections).
We outline these steps in the following sections.
BEGINNING THE CONFIGURATION PROCESS
1. Whenyou power on your system, theCyberSWITCH program automatically starts. Enter your
log-in id (
admin ). Next, enter a password.
2. Start up the configuration editor, CFGEDIT; at the system prompt, type:
cfgedit
Note: If you are unsure of any configuration values, use the defaults.
Use the displayed CFGEDIT menu to complete the remaining configuration steps.
PHYSICAL RESOURCE CONFIGURATION
1. Select Physical Resources from the main menu. Then, select Resource to display your
CyberSWITCH’s resources.
2. A displayof preconfigured resourcesand the pertinent slot numbers and switch types for those
resources appears.
3. Add all WAN resources. Depending on the type of WAN resource you have in your system,
select either a Basic Rate or Primary Rate resource from the displayed list of resources. If you
have selected Primary Rate, you should choose slave as the synchronization type. You will also
need to configure any expansion resources at this time if you selected Primary Rate. (Note: The
BASIC_RATE_NET resource type is a test facility. Do not select this for your resource type.)
After all resources have been added, return to the Physical Resource menu.
4. Configure the WAN lines. Select Data Line from the Physical Resources menu.After you select
to add a line you will be prompted for the line name. Enter LINE1 for the first line name. Next,
select the line’s slot number and port number from the displayed list. The information

requested to complete the line configuration will depend on the line type. The following
summarizes the information requested for each line type and the most common responses.
For Basic Rate:
• If you have a 4 port basic rate adapter, configure all basic rate lines at this time (up to four
lines)
• select point-to-point for the interface type
• add a data link (two for DMS and NI-1 switch types)
• use Automatic TEIs for these data links
For Primary Rate:
• ESF is the most common framing type
• B8ZS is the most common line coding type
• chose common-channel as the signaling type
• select the length of the line from the CSU to the CyberSWITCH as line build out
5. Ifyou are using any accessesbesides switched accesses (suchas dedicated accesses, frame relay
or X.25) configure the access now. Select Access. Select the type of access you wish to configure.
Follow the on-screen instructions to complete the configuration.
Note: Frame relay and X.25 accesses are available only if you have purchased the additional
software module for packet switched accesses.
The initial configuration steps on the CyberSWITCH are now complete. Press <return> repeatedly
until you return to the main CFGEDIT menu. Continue with the Connectivity section to complete
remaining configuration steps.

C ONNECTIVITY
OVERVIEW
The Workgroup CyberSWITCH can communicate with various other CyberSWITCH products via
a PPP connection. This connection can be used to transmit data and provide remote management
of your remote systems with Telnet, TFTP and SNMP. We will describe how to set up a PPP
connection with other CyberSWITCH systems, including the CSX100. For these examples, we are
assuming that CyberSWITCH “Remote” is the remote system, and will want to call into
