F1: PC REQUIREMENTS
===================
The package is designed to operate on DOS-based PCs, running as a standalone
program. A minimum of 640Kbytes of memory, a floppy disk drive, a hard disk and
a network adapter card is required. At least 2.5 Mbytes of hard disk space is
required for the installed program. MS-DOS (R) version 5.x or greater is
required.
F2: SUPPORTED ADAPTER CARDS
============================
The package supports the following 3Com network adapter cards:
- EtherLink II (R) 3C503
- EtherLink II TP 3C503B-TP
- EtherLink II/16 3C503-16
- EtherLink III 3C509
- EtherLink III TP 3C509-TP
- EtherLink/MC 3C523B
- EtherLink/MC TP 3C533B-TP
- TokenLink(R) III 16/4 3C619 (see `TokenLink III 16/4 Packet Driver' below)
- Other (see `Configuring Non-Supported Cards' below)
XT (R), AT (R) and MCA (R) PCs and clones are supported. However, XT PCs will
only support 8 bit cards.
F3: FILES ON THE INSTALL DISK
=============================
The following files are present on your install disk :-
INSTALL.EXE - the program that will install the software
TFTPFLS.EXE - a self extracting file that contains the TFTP software
README - documentation on the Management Agent software
3COMTFTP.TXT - this file
DEINSTAL.EXE - the utility which removes all installed files
F4: INSTALLATION AND CONFIGURATION
==================================
The installation utility creates a directory structure on the hard disk of the
target machine. It also modifies config.sys and autoexec.bat as required. The
original versions of these files are retained so that the software may be
de-installed.
NOTE If you are installing TokenLink III 16/4 , you must first install IBM Lan
Support.
The installation process for the default configurations of the supported
network adapter cards is as follows:
* Insert the diskette in the drive A:.
* At the A: prompt, type install.
* Follow the screen prompts for the parameters you must enter or confirm.
These are:
1/ the IP address for the TFTP server
2/ the default gateway (router) IP address (optional - see below)
3/ and the sub-net mask. (a mask is generated automatically, but
you may change it).
These will be saved, along with other data, in the NETDEV.SYS file (see below).
When all the selections have been made, the files will be expanded into
appropriate directories. When you are offered the choice of how to handle your
system files, we recommend you opt for creating minimum config.sys and
autoexec.bat files. The other choices require editing of these files.
* When the installation is complete, you will be instructed to reboot the PC.
During the reboot, the system will pause. At this point, press CTRL C to abort
or any other key to invoke the server.
Once the computer has been re-booted, you must check for the correct MAC
address (if it is FFFFFFFFFFFF, refer to the Problem section below), and look
for other error messages. If clear and correct, the TFTP server is ready to
download a new software image. Should you wish to employ a non-default
configuration, refer to H: below. For information on how to use non-supported
adapter cards, refer to F9: below.
F5: OPERATION OF THE TFTP SERVER
================================
The TFTP server is designed for unattended operation. As part of the
installation process the installed software modifies the config.sys and
autoexec.bat files to load the server components and automatically start-up
the server.
The server listens for incoming TFTP transfer requests. The server will answer
requests sequentially, not in parallel. Simultaneous download is not possible.
It is not available for any other application. The TFTP Server supports the
NETASCII mode of transfer only.
Consult your 3Com managed device's User Guide for details of how to initiate
the download process.
It is essential that you have set the device's IP address before you attempt
to download. You must enter a filename, a server IP address and a destination
(target device). When a TFTP request is received, the server will validate
the filename and attempt to locate the file in one of the transfer
directories. Once initiated, the server provides you with information about
the status of the download.
You can cancel the server by pressing 'q'. This returns you to normal DOS
operation. Re-invoke the server using TFTP_S.EXE in the
\3COMTFTP\EXE directory.
F6: PACKET DRIVER
=================
Each network adapter card requires a packet driver. The packet driver is a
device driver or TSR that conforms to a specific software interface. Each type
of card installed needs a separate packet driver. For the supported 3Com cards,
packet drivers are supplied with the software. The installation program will
automatically set up the packet driver based on the information you have
provided during installation.
If you have a non-3Com or unsupported 3Com network adapter card, you can
normally obtain Public Domain packet drivers to drive your card. These are not
directly supported by the installation program. Load your packet driver to the
\3COMTFTP\EXE directory. Refer to the section on unsupported cards below.
The 3Com packet drivers are provided under the terms of the GNU General
Licence Agreement (a copy of which is held on this disk in \3COMTFTP\NOTICES).
These packet drivers and the associated source code are held on this disk in
\3COMTFTP\EXE.
F7: TOKENLINK III 16/4 PACKET DRIVER
====================================
The Token Ring packet driver IBMTOKEN is an Ethernet packet driver. The IBM
Lan Support program must be installed before it can be used. The TokenLink
Adapter must be used with default settings.
The Token Ring packet driver is provided under the terms of the GNU General
Licence Agreement (a copy of which is held on this disk in \3COMTFTP\NOTICES).
The source code of this Token Ring packet driver is held on this disk in
\3COMTFTP\EXE.
F8: CONFIGURING SUPPORTED CARDS
===============================
The standard configurations are designed to use the factory defaults for a
particular card. If you use a standard configuration, you will not have to
adjust the jumpers and switch settings on the card. Standard configurations
are available for all of the supported cards: refer to the manual which came
with the card. You can use the 3Com EtherDisk (R), which comes with your card,
to display the required data. If you use a non-standard configuration, you
will be asked during the installation to provide the details of the settings
on the card. Use the EtherDisk, which comes with your card, to display the
required data.
F9: CONFIGURING UNSUPPORTED CARDS
=================================
Use the installation process to select a card type of `Other'. This results in
a line being added to your autoexec.bat file. You must edit the autoexec.bat
file using a DOS editor. Change the line \3COMTFTP\EXE\rem replacing `rem' with
the name of the packet driver for your card and the appropriate settings.
The settings that are needed by the packet driver can be found by typing the
name of the packet driver without any settings. Make a note of the settings
that are required and enter appropriate values in the autoexec.bat file.
Hexadecimal values are entered in the form 0xN, where N is the hex number.
The usual settings are:-
Software Interrupt - 0x7e (this is the default value).
Hardware Interrupt - 0-15 (set on card: ensure that this does not
clash with any other devices).
Port I/O - 0xN (a three digit hex number, usually
between 200 and 3E0).
Cable Type - N (this is usually a flag; 1 for the normal
connection or 0 for AUI).
An example of a packet driver set is -
3C503 0x7e 3 0x300 1
| | | | |
| | | | Cable type
| | | Port I/O
| | Hardware Interrupt
| Software Interrupt
Packet Driver name
If you have installed the server on drive C, the line in your autoexec.bat file
will read :
C:\3COMTFTP\EXE\3C503 0x7e 3 0x300 1
Copy the packet driver for your card into the directory 3COMTFTP\EXE.
Ensure that NETDEV.SYS has been entered into your config.sys file as:
DEVICE=C:\3COMTFTP\EXE\NETDEV.SYS
where C is the drive that the server has been installed on.
Your machine must be rebooted for these changes to take effect.
F10: CUSTOM.EXE
===============
The custom.exe program, located in 3COMTFTP\EXE, is used to set-up the IP
address, default gateway, and sub-net mask for the server. The Install program
uses this to set-up your system with the values you enter.
You can, if you wish, use custom.exe directly. If you are going to run this
program, you should backup the netdev.sys file before proceeding.
To invoke the program change directory to \3COMTFTP\EXE and type
custom netdev.sys.
You will be presented with a menu driven interface which you can use to change
various settings. The most common settings you may wish to change are in the
'site customization' menu. It is here that you can set-up the IP address,
default gateway and sub-net mask. You can give a name to the server by which
it can be identified. You can also use this program to check the TFTP server
IP settings.
The changes will be saved to the netdev.sys file which is loaded by config.sys
file when the machine is booted.
F11: POSSIBLE PROBLEMS
======================
If, when you reboot your PC, an Ethernet address of FFFFFFFFFFFF is displayed,
or the server software does not load at all, your card has not been found.
Possible causes are:-
1) Problem: An incorrect value has been entered for the packet driver.
Action: Check that the settings on your card agree with the values you
have entered for the packet driver. You can do this by looking
at the physical card or by running the set-up utility that
came with your card.
2) Problem: The packet driver is conflicting with another piece of
software.
Action: If another network package is running on your PC, disable it
and try running the server again. You should not try and run
two network applications through the same card.
3) Problem: The card is conflicting with another piece of hardware.
Action: Check the interrupt that you have set on the card is not the
same as any other piece of hardware. A usual value that is OK
is 10, though this is only a guide.
The first request by a device to initiate a download (the client) may result
in the error message,
TFTP: ERROR FROM FOREIGN HOST
ABORTED BY CLIENT REQUEST
appearing, followed a few seconds later by a second request. This is normal
operation and shows the client validating the first block of data received,
before updating its non-volatile memory.
F12: DE-INSTALLATION
====================
A utility is provided to allow you to de-install the package from the hard
disk. The actions of this utility will be to restore your original config.sys
and autoexec.bat files and delete all server executable and data files from
the hard disk.
F13: TARGET DIRECTORY AND FILE STRUCTURE
========================================
The installation creates a directory on the target machine called 3COMTFTP. The
following sub-directories will be created also:
\3COMTFTP\EXE
\3COMTFTP\BACKUP
\3COMTFTP\xxx
The directory, \3COMTFTP\EXE, is used to hold the TFTP server program
(TFTP_S.EXE), the customised configuration file, NETDEV.SYS, and the packet
drivers (3C5??.COM) needed for the supported network adapter cards.
The directory, \3COMTFTP\BACKUP, contains the original config.sys and
autoexec.bat files.
The directories, \3COMTFTP\xxx, are used to hold the Management Agent
Images for the various managed devices.
F14: IP ADDRESS
===============
The TFTP server uses the Internet protocol. In this protocol every host
machine must have a unique Internet protocol address (IP address). If your
PC is already connected to a network, you should consult with your network
administrator who will be able to give you a suitable address.
If your site supports a number of sub-networks separated by IP routers, you
will need to configure the default gateway address.
IP addresses are 32 bit numbers which are usually written down in the so-called
'dot' or 'dotted quad' notation. This consists of four numbers separated by
dots (for example: 123.45.67.8). Each number should be in the range 0-255,
although in practice the values 0 and 255 have special meanings.
You should take great care to ensure that you do not use an IP address that is
already used (or visible) on your network. For this reason we can not supply
the server with a default IP address. You MUST enter a value for this field.
Consult your network administrator.
F15: DEFAULT GATEWAY IP ADDRESS
===============================
If the Hub you wish to serve is not on the same IP network or sub-network as
your own, you will need to access it via a gateway.
If you use a gateway, you must enter the IP address of the GATEWAY in this
field.
If you do not use a gateway, leave this field as 0.0.0.0
F16: SUB-NET MASK
=================
A Sub-Net Mask is calculated automatically by the server, based on the IP
address you entered. The calculated value will be inserted for you. This may
need to be changed depending on the addressing scheme in use on your network.
Consult your network administrator.
If the server and device are on the same IP network, ensure that the sub-net
mask of the device you are upgrading is the same as the server mask.
F17: SIMPLE EXAMPLE
===================
If your network does not use Internet Protocol, you may use a simple
point-to-point connection such as the suggested set-up below. The IP addresses
cited are only examples to show the format. Whatever IP parameters you use, you
MUST either:
a) de-install the server software, or
b) reset the parameters to null (0.0.0.0)
IMMEDIATELY after the download.
TFTP server<------------------------------------->LinkBuilder Device
192.168.100.1 IP Address 192.168.100.n
0.0.0.0 Default Gateway/Router IP Address 0.0.0.0
255.255.0.0 Sub-Net Mask 255.255.0.0*
* On the LinkBuilder FMS, this should be entered in hexadecimal notation,
i.e.: FFFF0000.
In the above diagram, n is a number between 2 and 254, and is unique for the
each LinkBuilder Unit on the network.
If you have any doubt at all, consult your network administrator.
