Ref: 99980159 Title: Administrator Release Notes for 3+ 1.3.1 Date: 11/9/88 Copyright 3Com Corporation, 1991. All rights reserved. This document provides information related to the 3+ version 1.3.1 network software. Read this information carefully before installing or using 3+. This set of release notes is divided into eight sections: * Installation and Configuration * 3+NetDOS * 3+Backup * Remote Console * Disk Configuration * 3+Menus * NetBIOS * 3+Route and 3+Remote The abbreviated titles for the guides that the release notes reference are: 3Server386 3Server386 Guide Admin 3+ Administrator's Guide Install 3+ Installation and Setup Guide Mail 3+Mail User Guide Menus 3+Menus Reference Guide NetDOS 3+NetDOS Installation Guide QInstall 3Server3 and 3Server386 Quick Installation Guide Remote 3+Remote User Guide Start 3+Start Supplement for the 3S/400 TokenLink TokenLink Installation Guide Tuning 3+ Network Tuning Guide User 3+Share User Guide .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 Primary Secondary Ethernet on Token Connection Board Motherboard AppleTalk Token Ethernet on Motherboard Connection AppleTalk Board 3Server386 Primary Secondary Ethernet on EtherLink Motherboard EtherLink II EtherLink Plus TokenLink TokenLink Plus* AppleTalk on Motherboard TokenLink Ethernet on Motherboard TokenLink TokenLink Plus* AppleTalk on Motherboard * Must use DMA = 5 PC Server Primary Secondary EtherLink II EtherLink EtherLink II EtherLink Plus TokenLink TokenLink Plus* EtherLink Plus EtherLink EtherLink II EtherLink Plus TokenLink TokenLink Plus* TokenLink Plus EtherLink EtherLink II EtherLink Plus TokenLink TokenLink Plus* EtherLink/MC EtherLink/MC * Must use DMA = 5 .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 error code: 0302 00 OR code: 0303 00 OR code: 0304 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.
