.H1;Installation
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.

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.

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.

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:).

Installing 3+Backup on a Server without a 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.

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.


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.

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.

.LT
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 ?
.EL

This saves the changes and exits the 3EDLIN program.

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.  No jumper changes are necessary.

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.

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.

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.

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.


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.

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.

Standard Configuration Number 6

Installation and Configuration, p. 4-8

Configuration number 6 no longer contains 3+Route service.

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.

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

.H1;Administration

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.

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 ormore 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 Folder.


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)
