.h1;Installation and Configuration

TokenLink Plus Adapter in all PC Servers

For best performance and reliability, the TokenLink Plus adapter
is recommended for all PC servers on a token ring network, rather
than the standard TokenLink card.

EtherLink Adapter in a PC Server

For best performance and reliability, the EtherLink II or
EtherLink Plus adapter is recommended for all PC servers on an
Ethernet network, rather than the standard EtherLink board.  This
recommendation is strongly advised if you have Macintosh
computers on the Ethernet network that will be accessing the
server frequently.

Location of the Network Number on 3Com

 Servers with a Tape Drive
 QInstall, p. 2-17, 3-15
 Install, p. 6-3

If you purchased a 3Server3 or 3Server386 with a tape drive
(models 3S/201, 3S/202, and 3S/401), the network number for the
server is found on the 3+ System Tape included with the unit.
You may be required to enter this number when you install the
unit.  The instructions in the 3Server3 and 3Server386 Quick
Installation Guide and the 3+ Installation and Setup Guide refer
you to 3+Share/Server Name diskette for the number, but this disk
is not included with servers containing a tape drive.

The 3+Start Supplement for the 3S/400 now applies to
3S/200 servers as well.

.h1;Creating the First PC Netstation Startup Disk

3+ Installation and Setup Guide, p. 10-4

The procedure for creating a netstation startup diskette on page
10-4 is incorrect if you installed a PC server.  The procedure
instructs you to use the Quick Installation Workstation diskette
for a new network.  However, this diskette is not included in the
PC server version of 3+Share 1.3.1 (3C2000G).  Consequently, to
make your first PC netstation startup disk on a PC server, use
the following procedure.

1. After you install the 3+ software on the PC server, reset the
server and wait for the server menu to appear.

 1. Start up as a dedicated server.
 2. Start as a workstation
 3. Run the 3INS program
 4. Run the 3OPT program
 5. Exit to DOS

This is the server menu for a dedicated PC server.

If you designated the PC as a concurrent server, the menu will
include an additional option for running the server in the
concurrent mode.

2. Select the option Exit to DOS.

3. Change to drive C:.

4. Change to the \APPS subdirectory with the DOS CD command:

   CD \APPS

5. Go to Step 4 on page 10-5 in the 3+ Installation and Setup
Guide and perform the MAKEDISK procedure.  You may run the
MAKEDISK program as many times as necessary to create your
startup disks.

6. Reset the server and wait for the server menu to appear.

7. Select the option to start the PC as a network server.

Future PC startup disks can be created by following the procedure
as given in Chapter 10 of the 3+ Installation and Setup Guide.

.h1;Quick Installation on a Token Ring Network

Running the Quick Installation program on a server connected to a
token ring network may produce the following error message on the
server's LCD at the end of the procedure:

 Interrupt - F  (on a 3Server3)

 or

 Sync ILoop Test
 Failed   (on a 3Server386)

The error message may also appear when you reset the server from
a netstation, such as after running SETUP.  To recover from the
error, reset the server.  It will start up and operate normally.

.h1;Repartitioning the Hard Disk on a 3Server3 or 3Server386

If you repartition the hard disk in the 3Server3 or 3Server386,
you must run the 3OPT program after partitioning the disk and
save the new CIOSYS values.  Otherwise, the server will display
the error message Interrupt - 6 on the LCD.  To save the new
CIOSYS values, do the following:

 1. Start the 3OPT program with the server in the off-line mode
(see the 3+ Network Tuning Guide for instructions).

 2. From the 3OPT Main Menu screen, select the CIOSYS option by
highlighting it with the selection bar and typing 'C'.

 3. With the CIOSYS menu on the screen, press [Ctrl]+A to save
the current values.  No changes are required.

 4. At the 3OPT Main Menu, type 'S' for Save.

 You may now reset the server for normal operation.


.h1;Installing 3+ 1.3.1 on a 3+ 1.3 or Earlier Server

To install 3+ 1.3.1 on a server that already contains an earlier
version of 3+, you must back up the server to tape or diskette,
reformat the disk, install 3+ 1.3.1, and then restore your
application programs and data files from tape or diskette.  Do
not attempt to load 3+ 1.3.1 over an earlier version of 3+
without performing these steps.  If you have a 3Server3 without a
cache card, you may have to retune some of the services.


.h1;The 3ComEMM Memory Management Program

Install, p. 13-6

The LIM 4.0 driver which ships with this release of 3+ is the
only LIM 4.0 driver which is fully supported.  This driver is
supported on PC 386-based computers adapted as network servers
only.

The effectiveness of the 3ComEMM memory management program on a
PC 386-based server may be jeopardized by the type of video card
in the server.  Some video cards require more memory than others;
consequently, the more memory required by the card, the less
memory available for 3ComEMM to delegate to 3+ services.  If your
objective is to optimize the services loaded into high memory on
these systems, it is recommended that you use a monochrome card
and monitor in a PC 386 server.

.h1;The 3ComEMM Program on a PS/2 Model 80 as a Server
Install, p.13-6

The 3ComEMM memory management program for PC servers is not
supported on the PS/2 model 80 with an IBM Fixed Disk adapter.
However, the program is supported with the ESDI adapter.  To
determine the type of disk adapter in a PS/2 model 80, use the
Reference Disk included with the computer to view the system
configuration.  If you are still uncertain, contact your IBM
dealer for assistance.

.h1;The 3ComEMM Program on a Honeywell 386 Computer

The 3ComEMM memory management program is not supported on a
Honeywell 386-based computer using a token ring adaptor.

.h1;Adding a New Property for the Macintosh Service

If you connect a 3+ 1.3.1 server to an existing 3+ 1.3 or earlier
network and if the 3+ 1.3.1 server has the 3+ for Macintosh
service installed and enabled, do the following:

1. At a PC netstation with at least one floppy drive, log in to
the network as an administrator.

2. Check to be sure that you have a search path to a directory
containing the 3N command.

3. Insert the 3+ for Macintosh installation diskette into drive
A: of the netstation.

4. Make the current drive A:.

5. Enter the following command:

   ADDPROP

This program adds a new property to your existing network so that
it recognizes the Macintosh service on the new server.  If you do
not execute these steps, your network and the Macintosh service
will operate properly; however, when you display a status of the
Macintosh server, the service will not be displayed as being
installed.

.h1;Serial Ports COM2: and COM3: on a 3Server386

If you connect an AppleTalk network to a 3Server386 via
NetConnect, serial ports COM2: and COM3: on the server cannot be
used.  If you need additional serial ports, install a serial
adapter board (for example, the AST Four-Port serial board),
being sure not to configure the new ports as COM2: and COM3:.

.h1;Serial Ports COM4: and COM5: on a 3Server3

If you connect an AppleTalk network to a 3Server3 that has a Port
Expansion Board, serial ports COM4: and COM5: on the server
cannot be used.

.h1;Disabling the NetConnect Service

The NetConnect service cannot be disabled.  If you want
to disable the service, you must remove it with the 3INS
utility.

.h1;Changing the Baud Rate on a Microcom Modem

To adjust the baud rate on a Microcom modem, change the modem's
rear switches to the desired baud rate and then reset the modem.
If it fails to hang up correctly after this procedure, follow the
directions in the Microcom manual to change the modem back to its
default settings.  Then repeat the earlier step of adjusting the
rear switches and resetting the modem.  If the modem is installed
on a server, run the 3INS program and adjust the port settings to
the new baud rate and reset the server.

.h1;3+ 1.3.1 Server Using Both Ethernet and LocalTalk

If a 3+ 1.3.1 server has Ethernet and a secondary AppleTalk via
NetConnect, it is recommend that you set the following values to
the same setting.  The recommended setting is 8 or 10.  The
parameters are:

  * The Ethernet hold-back buffers (-h).  This parameter
    is a part of the ETH3.SYS or ETH386.SYS line in
    the server's CONFIG.SYS file.

  * The AppleTalk driver buffers (-b).  This parameter is
    a part of the 2APPLE.SYS or 2APPLE38.SYS line
    in the server's CONFIG.SYS file.

  * The 3+Share receive buffers set with 3OPT.

  * The NetConnect receive buffers set with 3OPT.

If you choose not to follow this recommendation, you should
review the following requirements before setting your own values
for the above parameters.

* The number of Ethernet hold-back buffers (-h) in the server's
CONFIG.SYS file must equal or be greater than the number of
3+Share receive buffers,

 and

* The number of LocalTalk buffers (-b) in the server's CONFIG.SYS
file must equal the number of NetConnect buffers.  This value
must be equal to or greater than the number of 3+Share receive
buffers.

.h1;Naming a Server with International Characters

The LCD on the 3Server3 and 3Server386 is not designed to display
international characters.  Consequently, it is recommend that you
use only the English alphabet (A through Z) and/or numbers when
naming the server.  If you do use international characters, the
LCD will either not display the name or will display the name
incorrectly.  However, this will not affect the operation of the
server.

.h1;The Canadian/French Keyboard

A netstation with a Canadian/French keyboard must use the French
software driver.  The Canadian/French software driver is not
supported on by 3+.

.h1;Status.Log File on a PC Server

The following error messages are inserted in a PC server's
Status.Log file every time you turn on or reset the unit:

 Could not init power fail driver
 Power fail initialization failed

These messages are associated with a 3+ feature that is supported
on the 3Server386 only.  They do not indicate a problem with the
PC server and no action is required.

.h1;Installing Internal Modems on a Token Ring Network

If you install an internal modem in a server, set the modem
switch to COM2.  This sets the modem to use interrupt level 3.
If you have any other adapters using this interrupt, either
reconfigure them or remove them.  (This is the default interrupt
setting for 3Com's Ethernet and Token Ring adapters, but this
does not conflict with the Ethernet on the 3Server3 and
3Server386 motherboard.)

Once set, this modem appears as a COM4 option in your
3+Route, 3+Remote, or 3+Print checker, similar to an
IBM AT card.

.h1;Supported 3+NetConnect Configurations

The following combinations of adapters for primary and secondary
networks are the only configurations supported with 3+NetConnect
on the three types of servers.

3Server3

.h1;Compaq Portable or Deskpro Computers

For proper operation, a Compaq 8088-based Portable or 8086-based
Deskpro requires ROM Revision J.  To find out what Compaq ROM you
have:

 1. Start your Compaq using the Compaq diagnostics diskette.

 2. Type test and press [Return].

 3. Choose option 5, ROMREV.

The version of your ROM is displayed.  ROM upgrades are available
from your Compaq dealer.

.h1;Printing from PageMaker 3.0

PageMaker 3.0 will not download the Aldus Prep file if it senses
that it is printing to a network spooler.  To print in PageMaker
3.0, the user must do either of the following:

 1.   Use only the Apple driver when printing.

 2.   Use the Aldus driver, but turn on the checkbox to download
the Aldus Prep file temporarily.  (This has been the
recommendation in the past, but this is now mandatory for
printing in PageMaker 3.0.)

.h1;Inserting Spaces in Filenames

When you create or rename a file from a Macintosh or PC
netstation, do not give the file a name that has a period (.)
followed by a space (for example, XYZ.  AA).  The file will be
inaccessible.  If this should occur, the only way to recover the
file is by resetting the server in maintenance mode and renaming
the file.


.h1;Communications with a PC Server

If the netstations in the network are unable to communicate with
a new PC server, even though the server started up properly, it
could be that the settings on the network adaptor in the server
do not match the settings in its CONFIG.SYS file.  For
instructions on the network adaptor settings, refer to the
adaptor guide.  For instructions to the CONFIG.SYS file, refer to
the 3+ Administrator Guide.

.h1;3+NetDOS

Note:  The 3+NetDOS program comes standard with the 3Server3 and
3Server386 and is available as an option for PC servers.

 Checking Out an MS-DOS License
 NetDOS, p. 2-3, 2.6

The reference to the MS-DOS Supplemental Diskette in the
3+NetDOS Installation Guide should read 3+NetDOS Supplemental
Diskette.

 Inserting a Blank, Formatted Diskette
 NetDOS, p. 2.6

When you insert the newly formatted diskette into the drive,
check to be sure the disk is not write-protected and that it is
properly inserted in the drive.  If 3+NetDOS encounters a problem
with the disk, you may have to repeat the procedure.

 Storing all System Files on One 3 1/2-Inch Disk
 NetDOS, p. 2-7

When you check out a 3 1/2-inch system diskette with 3+NetDOS,
all of the system files can be placed on one diskette rather than
two.  To do so, press [Return] without changing diskettes when
3+NetDOS prompts you for the second diskette.

 Creating Long Directory Paths
 NetDOS

Do not create paths over 63 characters in length.  Paths longer
than this can cause problems for some MS-DOS utilities, such as
XCOPY.

 Mixing Different Versions of DOS
 NetDOS

Do not mix different versions of MS-DOS.  For example, using MS-
DOS 3.2 utilities on a netstation booted with MS-DOS 3.3 will
result in the error message:

 Incorrect DOS version

 Recovering from an Error
 NetDOS

If 3+NetDOS experiences an error when you check out a license
(e.g., a faulty disk drive), select the abort option and repeat
the procedure.  If the number of available licenses is reduced by
1 even though you aborted the operation, edit the NETDOS.USR file
in the 3+NetDOS directory with a word processor or text editor
and increase the line "Available Licenses" by 1.

.h1;3+Backup

 Restoring Macintosh Files from Tape
 Macintosh

Before you restore Macintosh files from tape to a network server,
be sure to review the procedure in the 3+ for Macintosh
Administrator's Guide.  There are a few limitations that you need
to be aware of before you perform the procedure.

.h1;Remote Console

 3C with TokenLink
 TokenLink, p. 4-5

When you use 3C from a netstation with a TokenLink adapter board
installed in a 16-bit expansion slot, you must edit the
CONFIG.SYS file of the netstation startup diskette.  Change the
default DMA channel setting of 1 to 3 to make the 3C connection
work properly.  If you copy files from diskette to the server
using a netstation containing a TokenLink board that is using DMA
channel 1, the copied files will be incomplete or damaged.  (The
files on the diskette will be unharmed.)

 NOTE: If the TokenLink board is installed in an 8-bit
expansion slot, no special action is necessary.

Use a text editor to change the following statement in the
CONFIG.SYS file of the netstation startup diskette:

 DEVICE=TOK603.SYS ,, 3

This statement keeps the TokenLink board's default values intact
for the interrupt level (3) and I/O base address (300), but
changes the DMA channel setting to 3.  See the TokenLink
Installation Guide for more information on setting 3+ software
for this board.

 CAUTION: Before restarting the netstation with the updated
CONFIG.SYS file, make sure no other expansion board installed in
the netstation uses DMA channel 3.  If there is such a board
installed, either use a netstation that has no conflicting
expansion board (and change the first netstation's CONFIG.SYS
file back to its previous state);  or, remove the conflicting
board when using the CONFIG.SYS file that specifies DMA channel 3
for the TokenLink board.

.h1;Disk Configuration

 Number of DOS Volumes
 3Server386, pp. 5-30 and 5-41 through 5-49

If you have five or more 150 MB disk drives attached to the
3Server386, and each contains the default format of 512 bytes per
sector and 4 sectors per cluster, the system will have more than
the maximum allowable number of DOS volumes.  Up to 24 volumes
are allowed (one each for drives C: through Z:).  When you
display the configuration through the 3DISK386 "Show DOS volumes"
option, any volumes after the 24th (drive Z:) are listed as
question marks (?).

When five or more disk drives are attached to the 3Server386, or
the number of DOS volumes exceeds 24, format one or more disk
drives to have fewer, larger volumes than the defaults create.
(See the 3Server386 Guide, p. 5-45 for details.)

Attempting to restart the 3Server386 when more than 24 volumes
are defined halts the server and displays one of the following
messages on the LCD:

 Disk <SCSI ID/logical unit number> error
 code: 0302 <volume> 00 OR
 code: 0303 <volume> 00 OR
 code: 0304 <volume> 00

.h1;3+Menus

 Listing Users Linked to a Printer
 Admin, p. 4-4

The List Users Linked to a Printer menu selection produces an
error message:

 ***Unknown value: \LASERJET /LINK

and does not produce the desired list.  To see the list, modify
the form by typing the printer name after the server name on the
same line, and deleting the second line.  This is not a permanent
solution.

If you use this selection frequently, change the task item form
following instructions in Chapter 5 of the 3+Menus Reference
Guide.  Put the server and printer names on the same line.

Backing Up and Restoring from 3+Menus

Do not use 3+Menus to backup or restore a server's hard disk to
tape.  Instead, use the 3B command line commands.  Files may be
damaged or lost if this caution is not observed.


.h1;NetBIOS

NetBIOS /C Switch

Unless you are running only 3+ services, use the /C  switch on
the NetBIOS line of the AUTOEXEC.BAT file.  NetBIOS assumes that
timeout errors on SEND and RECEIVE, as well as Locator operations
that do not complete, are the result of physical network
problems.

To avoid terminating sessions because of such problems, NetBIOS
displays the message:

 Network Retrying ...
  or
 Locator Not Responding

You can wait for the network problem to go away or you can return
the timeout error to the application immediately by pressing
[Ctrl]+[Break].

When a NetBIOS application relies on getting these timeout errors
as a normal part of its operation, using the NetBIOS /C switch
returns the timeout error to the application immediately without
displaying a message.

NetBIOS /M Switch

The IBM Asynchronous Communications Server and the IBM PC LAN
programs require the NetBIOS /M switch.

.h1;3Server3 with Locator

A 3Server3 with the Locator service may hang if you reset it at
the same time that you reset a netstation that uses the full
implementation of NetBIOS.  The server will stop with the message
Loading Locator or Loading Share on the LCD.  To remedy the
problem, turn off or rest the netstation.

.h1;3+Route and 3+Remote

3+Route on Token Ring

When running 3+Route on a token ring network, you may
occasionally experience loss of modem connections.  This
typically occurs on COM2 or COM3 while operating under heavy
loads and at baud rates equal to or greater than 9600 baud.  If
this occurs , move the high speed modem to COM1 or to an
asynchronous I/O port on an expansion board.

Mixing Hayes and Microcom Modems

When you use a Microcom mode in SX mode, you must have one on
both the originating and answering systems.  That is, if your
server has a Microcom modem configured in SX mode, only PCs or
other servers that are using Microcom modems in SX mode can
communicate with each other.

If you need to use Hayes and Microcom modems interchangeably, you
may configure your Microcom AX1200 or AX2400 for Hayes
compatibility rather than SX mode.  See Appendix B of the 3+
Installation and Setup Guide for detailed information.
