regarding the enclosed computer software package, its merchantability
or its fitness for any particular purpose.  The exclusion of implied
warranties is not permitted by some states.  The above exclusion may
not apply to you.  This warranty provides you with specific legal
rights.  There may be other rights that you may have which vary
from state to state.

.H1;Installation
.H2;Server Models Supported
3+ for Macintosh can be installed on a 3Server or 3Server3
running 3+ version 1.1 or higher, as well as on a 3S/200
running 3+ version 1.2.1 or higher.  The 3S/400 server
running 3+ version 1.3 does not support 3+ for Macintosh
version 1.2.1.  3+ for Macintosh support on the 3S/400 will
be included in a future release.


.H2;3+Route and 3+NetConnect Support
In this release, Macintosh netstations cannot use 3+Route to
access Shared Folders and printers on remote servers via
modem and telephone line connections.  IBM PC and PC
compatible users can continue to use 3+Route to send and
receive messages with 3+Mail.  Full 3+Route support for
Macintosh netstation users will be included in a future release.

However, you can configure your network to support multiple
servers by connecting the servers with Ethernet.  Each server
on the network can have an Ethernet segment and an
AppleTalk segment attached to it.  Macintosh users on
AppleTalk can then access Shared Folders or shared printers
on any server on the network.  Internetworking is not
supported on Macintoshes directly connected to Ethernet.
This will be supported in a future release.

.H2;3DISK Server Software
When installing the system software on a 3S/200 server, be
sure that you only use the 3DISK that comes with the 3S/200
server on the systems software diskette.  The 3S/200 version
of 3DISK is intended only for this specific server and is not
interchangeable with any other 3DISK.

.H2;Using 3DISK
After reformatting SCSI Bus 0 Drive ID 0 with 3DISK, use
default values for the bytes per sector and sectors per cluster
parameters for the first partition (C:).

.H2;Installing 3+Backup without Tape Unit
Make sure that you do not install 3+Backup on a network
server unless you also have a tape unit installed on this server.

.H2;3+ for Macintosh and Appleshare
3+ for Macintosh and Appleshare client software work
together on the same Macintosh netstation.

However, if you decide to convert an Appleshare server to a
3+ for Macintosh netstation, you must replace the System
Folder on the startup hard disk with the 3+ for Macintosh
System Folder.  This folder is on the 3+ for Macintosh user
diskette.

.H2;Installing the Locator Service on a 3Server
Installing the Locator service on a 3Server with the maximum
possible service configurations may require that you edit your
CONFIG.SYS file to increase the -b option on the Ethernet
drivers.  For more information refer to Appendix D in the 3+
Installation and Configuration Guide.

.H2;Disabling Printed Error Messages
If a printer error occurs when a document is printing,
PostScript printers attached to a 3+Share server will print an
error message.  You can disable message printing by
modifying the 3PLUS ON.BAT file on the server.  Follow
these steps to make the modification.

1. Establish a 3Console connection to the server.

See Appendix A of the 3+ for Macintosh Supplement for
details on establishing a 3Console connection.

2. At the C>> prompt, type:

3EDLIN \3CONFIG\3PLUS_ON.BAT ?

3. At the * prompt, type:

375

The screen displays the following:

 375:* 3share
 375:*

4. Type:

3Share /D=001 ?

The /D=001 parameter tells 3+ not to print error
messages on the printer.  If you change your mind later
and want the messages to be printed, follow these steps
again, omitting the /D=001 parameter.

5. Type:

E ?

This saves the changes and exits the 3EDLIN program.

.H2;Installing with a Port Expansion Board
Supplement, p. 2-1

If your 3Server3 has a port expansion board installed,
you must connect the AppleTalk cabling to the
AppleTalk port on the port expansion board.

In addition, do not use Com port 4 to connect a serial
device to a server.  This combination hangs the server
when you access the serial device.  For instance,
connecting a Laserwriter to Com port 4 on a server with
AppleTalk installed hangs the server when you print.

.H2;Installing with 3+ Version 1.2
Supplement, p. 2-7

If your server has 3+ version 1.2 installed, your PC
netstations are using NetBIOS, and you are adding 3+
for Macintosh, check parameters for all services after
installation.  Make sure the Locator is installed on one
and only one network server, usually the Name
server.  Otherwise, the network will not operate
correctly.

.H2;Installing Apple's EtherTalk Software
Supplement, p. 2-7

Install Apple's EtherTalk software using only their
Installer Program.  Refer to the documentation that
comes with your Ethernet board for details on setting up
Ethernet.

.H2;Installing with 3+Route or 3+Remote
Supplement, p. 2-7, 2-11

Installing 3+NetConnect alone without deinstalling
3+Route or 3+Remote will result in the message:

Runminds Failure

on the server's LCD during startup.  If your server has
3+Route or 3+Remote installed before adding 3+ for
Macintosh, you must do one of the following:

Deinstall 3+Route or 3+Remote.

Choose Install Individual Services from the
3INSTALL main menu and install either
3+NetConnect and 3+Route or 3+NetConnect and
3+Remote.

.H2;Installing and Configuring Services
Installation and Configuration, p. 4-7

When in the 3INSTALL main menu and attempting to
View and Install the Standard Configuration sets, the
command line "Forward/Backward" option suggests you
can scroll through the configuration selections.  In 3+
for Macintosh you must not scroll backwards through
these configuration sets.  Scrolling backwards can cause
an error to occur that removes you from the 3INSTALL
program.

However, if you do encounter this error, type
3INSTALL and press [Return] at the prompt to return to
the 3INSTALL main menu.

.H2;3+Share Parameter Adjustment
Installation and Configuration, p. 5-60

The default message buffer size for 3+Share for
Macintosh is 2608.  For best results, we recommend
you use this setting.  If you configure a message buffer
size larger than 4144, Macintosh netstations may lose
their connections to network servers under heavy server
load conditions.


Installation and Configuration, p.5-57

The 3+Share for Macintosh packet receive buffers are set
by default to 8.  For best results, we recommend you
use this setting.  If you adjust the packet receive buffers,
make sure they are configured to a number less than the
ETH3 -h parameter in your CONFIG.SYS file.  For
complete information on the ETH3 -h parameter, see
Appendix D of the 3+ Installation and Configuration
Guide.

.H2;CIOSYS Parameter Adjustment
Installation and Configuration, p. 5-56

3+ for Macintosh requires the CIOSYS file descriptors
and file handles to be set to a higher value than what is
normally used for PC netstation configurations.  For
best results set the number of file descriptors to 200 or
more.  For further information refer to the 3+ Installation
and Configuration Guide.

.H2;Standard Configuration Number 6
Installation and Configuration, p. 4-8

Configuration number 6 no longer contains 3+Route
service.

.H2;Macintosh Service Parameter Adjustment
Supplement, p. B-1

Installation and Configuration, p. 5-36

The number of Macintosh threads must be less than or
equal to the number of CIOSYS threads.  If Macintosh
threads are set to a higher number than CIOSYS threads,
the setting for CIOSYS threads is used.  If you want to
increase the Macintosh threads, first change the CIOSYS
threads parameter, select Keep to save the changes, then
adjust the Macintosh service threads.  For further
information refer to the 3+ Installation and Configuration
Guide.

.H2;Manual Errata
Supplement, p. 3-8

The default for number of buffers used by
3+NetConnect  is 8.

Supplement, pps. 3-11, B-6, B-8

The following mappings have been added to the default
Extension Mapping Table:

DOC=MSWD,WDBN Microsoft Word Version 3.01
file

STY=MSWD,TEXT Microsoft Word Version 3.01
style sheet

GLY=MSWD,TEXT Microsoft Word Version 3.01
global style sheet

TIF=ALD2,TIFF PageMaker Version 2.0a TIFF
format picture file

Additionally, the last extension mapping shown in
Tables B-2 and B-3 should read as follows:

<Any other extension>=3MAC,TEXT

.H1;Administration
.H2;3+ Backup

Checking the Tape Backup Log

After performing a backup, make sure that all the files were
backed up by checking the backup log.

User Level Backup

3+Backup server software versions 1.2.1 and 1.2.2 do not
support user level (directory) backup or the Log command.
PC or PC compatible users will lose these two functions over
the old backup server software version 1.2.  If the user is
running PC client 1.2 software on top of 1.2.1 or 1.2.2 server
software, the Log command will always return an "empty log"
error message.  As a result, nothing will get backed up from
the user level backup, but a "backup in progress" error
message will still be displayed.

Backing Up to Multiple Tapes

When you are performing a backup operation that requires
more than one tape, on certain hardware configurations you
may see the message "See Backup Log" on the LCD just after
inserting the second tape.  If the backup log contains the
message

Internal error 10.  rc=17.

contact your 3Com reseller.

New Printer Status Capability

The Show Status item on the Printer menu now displays the
print queue for the currently linked printer if you do not have a
printer selected in the 3+ Network Window.

If no printer is linked or selected, then the Show Status menu
item is disabled.

.H2;General Issues

Switching Between AppleTalk and Ethernet

To switch network media between AppleTalk and
Ethernet, you must log out and then select the Control
Panel from the Apple menu.  Click on the network icon,
then on either Builtin (AppleTalk) or EtherTalk, and
restart your Macintosh.  If you are switch launched,
restart your Macintosh without switch launching and
perform the steps above.  Refer to the EtherLink/NB
Installation Guide for more information.

Logging Out and Emptying the Trash

3+Share for Macintosh User Guide, p. 2-23

Dragging files into the Trash and logging out from 3+
for Macintosh, without first selecting the Empty Trash
option from the Special menu, will not discard the files
in the Trash.  Throwing away files is a Finder activity,
and logging out unmounts the Shared Folder.  The
Finder is unaware of the folder being unmounted, and it
cannot delete a file from a folder that is not currently
mounted.  When you log in again, the files you thought
you discarded will still be present in the Shared Folder.

Using a Kinetics Etherport SE Card

To use a Kinetics Etherport SE Card on a Macintosh SE
within a 3+ for Macintosh network, you must have the proper
version of the Kinetics software.  Be sure to ask your 3Com
reseller for the version that supports 3+ for Macintosh.  Refer
to the Kinetics documentation for more information.
Sharing a Folder as a Server-User
Administrator's Guide, p. 2-11

By logging into the network as a server-user, you can
create and share folders in one step.  These Shared
Folders can be accessed by all network users by
selecting the server's name in the 3+ Network Window
and clicking Open.  Because they are easy to find,
server-user Shared Folders are useful for storing
multiuser network applications or files needed by
multiple network users.

1. Log in as the server-user for the server on
which you want to create and share a
folder.

If you do not know how to do this, see "Logging
In as a Server-User" in Chapter 4 of the 3+ for
Macintosh Administrator's Guide.

2. In the 3+ Network Window, click Share.

When you first log in as a server-user, Share is
enabled.  This allows you to create a folder and
share it at the same time.  The following screen is
displayed.

3. Enter a Shared Folder name for the folder.

The Shared Folder name can be from 1 to 8
characters long with no spaces.  Use a name that is
descriptive of the folder's contents.  For example,
if the folder will contain applications, enter a
Shared Folder name of APPS.

4. Enter a password in the Password box, if
desired.

A password is not required.  However if the
Shared Folder is assigned Private access rights and
has no password, it will be inaccessible.

5. Enter the DOS path for the folder you are
sharing in the Path box.

For example, to create and share a new directory
for multiuser network applications, specify the path
C:\APPS.

The DOS path specifies the folder name and the
exact location on the server's disk where the new
folder will reside.  The DOS path always begins
with the drive designation where the folder will
reside.

Each folder you create from a Macintosh netstation
is represented by a DOS directory on the server's
disk.  In addition to the directories representing
your folders, 3+ creates directories on the server's
drive C: that are used to organize the system files.
You can see what partitions and how much space is
available on each by selecting the server's name in
the 3+ Network Window and clicking Getinfo.

The DOS directory structure is hierarchical the
same way Macintosh folders are hierarchical.  The
figure below illustrates the DOS directory structure
on drive C: of a server.

3+ Server Directory Structure

In a DOS pathname, the drive designator and levels of
the directory (or folder) hierarchy are separated by a
backslash (\).  Each level of the hierarchy is assigned a
name from 1 to 8 characters long with no spaces.  Using
this method, the path to the directory 3PLUS, shown in
the figure above, is C:\3PLUS.  The path to the directory
3NAME is C:\3PLUS\3NAME.

As server-user, you can create and share new directories
as well as share any existing directory on the server's
hard disk except the root directory (C:\).


6. Select the appropriate Access Rights for
the new Shared Folder.

Most Shared Folders created by the server-user
contain shared applications and files.  Read Only
access rights are usually appropriate for folders
containing shared applications.  The default access
rights are Read/Write/Create and are usually
appropriate for folders containing shared files or
applications that modify themselves.  When using a
multiuser network application, refer to that
application's documentation for more information
on the access rights you should assign to folders
containing the application's data files.

If you assign Private access rights, you must
assign a password.  Folders assigned Private
access rights and no password are not accessible.

7. Click OK to create the folder and Shared
Folder name.

The 3+ Network Window is displayed on the
screen and the new Shared Folder appears in the
list box.  Click Cancel to bypass creating and
sharing the folder.

Modifying a User

Administrator's Guide, p.3-22

Modifying your capability class from Admin to User or
changing the name of your Mail or Share server does not
take effect until you log out.  Prior to logging out, you
will continue to have access to Admin functions.

Deleting a Domain

Administrator's Guide, p. 3-27

Deleting the last domain in an organization causes the
organization to be deleted in the Name service.
However, the organization remains as the title of the list
box in the 3+ Network Window.  Changing the title of
the list box to Network removes the organization from
the 3+ Network Window display.

Adding Users

Administrator's Guide, p. 3-9

When adding users on your 3+ for Macintosh server, it
is not necessary to create a new domain for those users.
3+ for Macintosh uses the same Name service as the PC
netstations on your network.

User Name Character Limit

Administrator's Guide, p. 3-9

If you are using 3+Name version 1.2.1 or higher, when
you add users to your 3+ for Macintosh server, follow
the name:domain:organization scheme.  Limit the total
characters for the name to 39, and total characters for the
entire name:domain:organization to 56.
.H1;Error Messages
.H2;Changed Messages
Administrator's Guide, p. A-7

The message

Name server not responding.

indicates that the Name server is shut down, or disconnected
from the network, or busy with requests and unable to
respond to your netstation's request.  Make sure the Name
server is in operation, connected to the network, and no break
exists in the network cabling.  If the message occurs
frequently, move one or more 3+ services to a different
server.  If you are using a PC server as the network's Name
server and this message occurs frequently, try moving the
Name service to a 3Server or higher performance PC server.

Administrator's Guide, p. A-15

The message

 "server:domain:organization" is not
  responding.  Retrying...

indicates that the server is not responding to requests.  3+ will
continue trying to establish communication with the server
unless you cancel by pressing Command-. (period).
Cancelling the operation breaks all connections to the indicated
3+Share server.  Do not cancel the retries until at least one
minute has elapsed.  If you cancel, restart your Macintosh and
log in before continuing work.

Administrator's Guide, p. A-19

The message

The print queue is full.

indicates that the maximum number of print queue entries has
been reached.  Click 3+Print in the Chooser and look at the
print queue.  When one or more print jobs leaves the queue,
print the document again.  If the message appears frequently,
increase the maximum print queue entries allowed in the
3+Share Print service by using the 3INSTALL program.  See
Chapter 5 of the 3+ Installation and Configuration Guide for
instructions.

Administrator's Guide, p. A-19

The message

The print server's disk is out of space.

indicates that drive C: on the 3+Share server, to which the
printer is attached, is full.  Make space available on the drive
by removing unnecessary files in one or more user's Home
Folders, or move one or more user's Home Folders to a
different partition or server.

.H2;New Messages

Administrator's Guide

The message

 3+Admin is currently open.  You must quit 3+Admin to use 3+Print.

indicates that you are running the 3+Admin application in
MultiFinder, and you have selected 3+Print from the Chooser.
To select a printer or view the status of a particular printer, see
the instructions in the 3+ for Macintosh Administrator's
Guide.  Or, quit the Admin application first, and then use
3+Print.

Administrator's Guide

The message

Cannot link printer  <Additional Message.>

indicates that 3+ for Macintosh is unable to link to the printer
at startup.  Look up the additional message and follow the
action.  Two possible additional messages are:  "Server not
responding" and "Admin has disabled links to that printer".

Administrator's Guide

The message

 You cannot logout because you have switch
 launched.  Restart your Macintosh.

indicates that you have switch launched to the Finder or
MultiFinder on the network, are running the 3+Admin
application, and attempted to log out.  Restart your Macintosh.

.H1;Switch Launching
This section briefly describes switch launching.  Switch
launching allows you to switch from using the System Folder
on your Startup diskette to using a System Folder in another
location.

This  release of 3+ for Macintosh provides a way to
automatically switch launch to your network Home Folder
when you start up your Macintosh netstation, and at that time
eject your Startup diskette.

One advantage of switch launching, either manually or
automatically, is that once your Startup diskette is ejected you
can insert other diskettes without constantly having to swap
back and forth.  Another advantage is the ability to add any
desired fonts or desk accessories to your System file.  Since
you can have a System Folder on the network server, you do
not have to worry about available space on an 800K diskette.

NOTE:  You can only switch launch to your Home Folder.
Switch launching to other Shared Folders is not permitted.
This prevents two users from switching to the same System

Make sure that the latest versions of 3+ for Macintosh and
Apple system software are present in the Home Folder's
System Folder.  When you try to print after switch launching,
for example, you will get an error message if you do not have
3+Print in the Home Folder's System Folder.

1. Start up your Macintosh netstation using your
3+ for Macintosh Startup diskette.

2. Log in and link to your Home Folder and any
other Shared Folders or printers desired.

3. Copy the System Folder from your 3+ for
Macintosh Startup diskette into your Home
Folder.

4. Switch launch to your Home Folder.

 You can switch launch using any one of these methods:

Open any application resident in your Home
Folder.

Hold down both the Command and Option keys
and double click on either the Finder or
MultiFinder in your Home Folder's System
Folder.

Use NetSwitch or NetSwitch MF as described in
the following sections.

NOTE:  Make sure your Startup diskette is not set to
use MultiFinder.  Apple System software does not
support switch launching to another diskette or folder if
you are currently using MultiFinder.  When you switch
launch you can use MultiFinder from your Home Folder,
but you must still set the Startup diskette to use Finder at
startup.

NetSwitch

NetSwitch is a utility that allows automatic switch launching to
your Home Folder each time you start up your Macintosh
netstation.  The advantage of using this utility is the
elimination of confusion about which System file you are
using.  NetSwitch opens the Finder on the network.  If you
want to use MultiFinder, refer to the NetSwitch MF section.
If you do not have the NetSwitch application on your diskette,
contact your network administrator.

1. Start up your Macintosh netstation using your
3+ for Macintosh Startup diskette.

2. Log in and link to your Home Folder and any
other Shared Folders or printers desired.

3. Using the 3+ Network Window, save your
startup settings from the Status dialog box to
create a 3+Prep file on your Startup diskette.

4. Make sure you have a System Folder in your
Home Folder.

Copy the System Folder from your Startup diskette, if
necessary.

5. From the Finder, click on the NetSwitch icon.

6. Choose Set Startup... from the Special Menu.

7. Select Finder at the top of the dialog box;
select NetSwitch from the bottom of the dialog
box; click OK.

CAUTION:  At the top of the dialog box, be sure to
select Finder, not MultiFinder, and at the bottom of
the box, select NetSwitch.

8. Restart your Macintosh netstation.

You are automatically switch launched to the Finder on
the network, and your Startup diskette is ejected.

NOTE:  If you attempt to log out or unlink the Home Folder
after switch launching to it, a message appears indicating you
should shut down or switch launch to another diskette before
taking this action.

The Save Startup check box in the Status dialog box is
disabled after switch launching.  If you want to change your
Startup configuration, refer to "Changing Startup Settings
after Switch Launching" later in this section.

NetSwitch MF

NetSwitch MF operates the same way as NetSwitch, except
that it automatically runs MultiFinder instead of Finder from
your Home Folder.  The MF in NetSwitch MF stands for
MultiFinder.

1. Perform steps 1 through 4 from the previous
section.

2. From the Finder, click on the NetSwitch MF
icon.

3. Choose Set Startup... from the Special menu.

4. Select Finder at the top of the dialog box;
select NetSwitch MF from the bottom of the
dialog box; click OK.

CAUTION:  At the top of the dialog box, be sure to
select Finder, not MultiFinder, and at the bottom of
the box, select NetSwitch MF.

NOTE:  If you attempt to log out or unlink the Home Folder
after switch launching it, a message appears indicating that
you should shut down or switch launch to another diskette
before taking this action.

The Save Startup check box in the Status dialog box is
disabled after switch launching.  If you want to change your

Startup configuration, refer to "Changing Startup Settings
after Switch Launching" below.

Changing Startup Settings after Switch Launching
You can change your default 3+ for Macintosh startup settings
when using NetSwitch or NetSwitch MF.

To change your current 3+ for Macintosh startup settings:

1. Start up your Macintosh using your 3+ for Macintosh Startup
diskette.

If you followed the switch launch procedures in the
previous section, you are automatically switch launched
and the Startup diskette is ejected.

2. Insert the Startup diskette into the disk drive.

If you did not use NetSwitch or NetSwitchMF, the
Startup diskette will still be in the drive.

3. From the Finder, click on the Startup diskette
icon.

4. Choose Set Startup... from the Special menu.

5. Select Finder at the top of the dialog box;
select Finder Only from the bottom of the
dialog box; click OK.


CAUTION:  At the top of the dialog box, be sure to
select Finder, not MultiFinder, and at the bottom of
the box, select Finder Only.

6. Restart your Macintosh netstation.

7. Select Chooser from the Apple menu.

8. Click 3+File.

If you are already logged in, click Network.  If not, log
in and link to your Home Folder and any other Shared
Folders or printers desired.

NOTE:  If you unlink your Home Folder, you will note
be able to switch launch.

9. Using the 3+ Network Window, save your
startup settings from the Status dialog box to
create a 3+Prep file on your Startup diskette.

10. From the Finder, click the NetSwitch (or
NetSwitchMF) icon.

11. Select Set Startup... from the Special menu.

12. Select Finder at the top of the dialog box;
select NetSwitch from the bottom of the dialog
box; click OK.

CAUTION:  At the top of the dialog box, be sure to
select Finder, not MultiFinder, and at the bottom of
the box, select NetSwitch (or NetSwitch MF).

Every time you start your Macintosh netstation, the 3+ for
Macintosh Startup settings saved in this procedure are in
effect.

Minimal Boot Configuration

Even with switch launching, your startup diskette may be
almost full if you have many INIT files which need to be in
the System Folder of the startup diskette.  As an alternative, if
you switch launch and have copied your System Folder onto
your Home Folder and made a backup copy of your startup
diskette, you can put the following files on the network and
eliminate them from your startup diskette:

.BR;MultiFinder
.BR;Mouse
.BR;Keyboard
.BR;DA Handler
.BR;3+Icon Giver
.BR;NetSwitch or NetSwitch MF (whichever one you are not
using to automatically switch you to the network)
