These are some items to keep in mind when setting up the AppleTalk Internet
Router:
Memory Considerations
---------------------
- In general 1MB of RAM is sufficient for running the router. However, you
should consider the following exceptions:
- You must use 2MB of RAM when running the router concurrently with the
AppleShare File Server. You can add memory beyond 2MB, but that only
increases performance of the file server and not of the router. The reason
is that the file server uses all additional memory for its RAM cache.
- It is recommended that you use 2MB of RAM to run the router and the
AppleShare Print Server or the router and a mail server package
concurrently. As long as you have 2MB of RAM, you can also run the router,
the AppleShare File Server, and any single foreground application, like a
print server.
- To avoid memory problems, do not use MacroMaker on a 1MB router machine.
- Be aware that having MacsBug (or any other debugger) active reduces the
amount of memory available to the router. Do not run MacsBug on a 1MB
router machine or on a router that is also running the AppleShare File
Server.
- To avoid memory problems, do not use 32-bit QuickDraw on a 1MB router
machine.
- Best use of memory can be obtained by minimizing the INITs and desk
accessories that run concurrently with the router.
- Because of the way MultiFinder runs desk accessories, we recommend that
you run the router in single Finder. MultiFinder runs desk accessories in
the system heap. This means that when you use the router desk accessory
under MultiFinder, you are more likely to run out of memory, because the
router driver and any other concurrently running process take memory from
the system heap.
Printing
--------
Note that the following considerations refer to printing from the router
machine. These considerations do not refer to a workstation printing, even
if it reaches a printer through a router.
- Avoid background printing on a router machine. When Print Monitor opens
a printer driver, it uses up memory; the router desk accessory may then run
out of memory.
- Do not attempt 32-bit color printing from a router machine.
- Be aware that the 6.0 LaserWriter driver takes up much more memory than
the 5.2 driver. Avoid using the 6.0 LaserWriter driver on a 1MB router
machine. Also avoid using the 6.0 LaserWriter driver, when running the
router and the AppleShare File Server concurrently.
INITs and Desk Accessories
--------------------------
- INITs and desk accessories are not always well-written. They sometimes
use up memory behind the operating system's back. Try to live with as few
of them as possible.
- Close unneeded desk accessories. This includes the Chooser, which would
otherwise continually broadcast look-up requests on the network.
- Responder is OK when installed with the Router.
Upgrade Utility
---------------
- If a Phase 1 router is introduced to the internet after the routers have
been running in Phase 2 mode with network ranges for at least 15 minutes,
the Phase 2 routers issue an alert and do no conversion. You must restart
the router Macintoshes with the Upgrade Utility installed to restart the
conversion.
System Software
---------------
- The Router has been tested with System 6.0.3 and will be tested with
future releases. Older systems are not recommended.
Hard Disks
----------
- The Router is RAM based. A faster hard disk will not cause faster routing
of packets. (Improvements can be seen when using a faster hard disk with
the AppleShare File Server).
EtherTalk Card
--------------
- You should use a revision J or later EtherTalk card with the router.
- An improperly terminated EtherTalk card or a break in the EtherTalk
cable causes the router to take a very long time to load. An EtherTalk card
not connected to a cable must have a BNC "T" connector attached and
terminators attached to the "T".
- Make sure your EtherTalk card is properly set for thick or thin
Ethernet. If it is improperly set, no workstations or other routers on the
network can communicate with the router.
Removal of AppleShare File Server
---------------------------------
- The removal of AppleShare File Server software after installation of the
Router/EtherTalk/TokenTalk software will remove the AppleTalk file from the
System Folder. You must re-install either the router, EtherTalk 2.0, or
TokenTalk 2.0 software.
Installation
------------
- When using the router with TokenTalk, be aware that some customers were
seeded with an AppleTalk Phase 1 (1.0) version of TokenTalk. You should
remove TokenTalk 1.0, using the 1.0 Installer diskette, and then install
TokenTalk 2.0.
- Be aware that some customers were seeded with an AppleTalk Phase 1 (1.0)
version of the AppleTalk Internet Router. You should remove the 1.0
version, using the 1.0 installer diskette, and then install the 2.0
version. The ADEV files for the LocalTalk ports were renamed with the 2.0
version of the AppleTalk Internet Router. If you do not remove the 1.0
version of the router, the router setup window will show the old and new
ADEVs, causing you to have 4 LocalTalk ports.
