8.2.3
Overview
These installation instructions and release notes describe revision 8.2.3 of
the CoreBuilder
™
6000 Extended Switching software from 3Com
Corporation, dated October 9, 1997. This revision supersedes revision 8.2.1,
dated May 30, 1997.
Hardware
Dependencies
LANplex® Extended Switching software revision 8.0.0 or greater, or
CoreBuilder Extended Switching software revision 8.2.1 or greater, requires
that you have installed one of the following versions of the LANswitching
Management Module Plus (LMM+) in system slot 1:
■
Revision 1.21 or greater (for revision 1 modules)
■ Revision 2.12 or greater (for revision 2 modules)
If you attempt to run LANplex system software 8.0.0 or greater, or
CoreBuilder system software 8.2.1 or greater, on an earlier revision of the
LMM+, the system fails to reboot automatically when you turn it on.
To reboot a system that has failed to reboot automatically, connect a
terminal to the serial port on the LMM+ installed in the system. When the
system prompt asks whether you want to “ignore the checksum error,” enter
y
(for Yes). The system reboots.
Upgrading Your LMM or LMM+
To verify that you have an LMM+ module and not an LMM module installed:
1 Check that the module’s ejector tab is labeled “LMM+”.
2 Determine the revision of your LMM+. From the top level of the
Administration Console, enter:

If you have an LMM+ at a revision earlier than 1.21 (for revision 1 modules)
or 2.12 (for revision 2 modules), call 3Com at 1-800-876-3266 and press
option 2. 3Com will replace your LMM+ with an LMM+ at the correct
revision, free of charge. (Contact 3Com at the same number to upgrade an
LMM to an LMM+. There is a fee for this upgrade.)
Extended Switching
Software
Requirement
Release 8.0.0 or greater of Extended Switching Software requires a
minimum of 2 MB of memory on Ethernet/FDDI Switching Modules
(EFSMs). Memory configuration may vary. If you have an EFSM with 1 MB of
memory, you can order a memory upgrade. Contact your sales
representative.
To determine the amount of memory on the EFSM, look at the lower ejector
tab label or use the
system display
command from the top level of the
Administration Console. EFSMs with only 1 MB of memory have blank
lower ejector tabs. EFSMs with a minimum of 2 MB of memory have “2MB”
on the lower ejector tab labels.

For more information about this release, see “What’s New at Revision 8.2.0?”
on page 14.
Before You Start Before you install your new software, read all of these release notes.
Carefully read “System Issues” on page 23 and “Known Problems” on
page 26.
The top-level menus in your Administration Console may vary from those
illustrated in these release notes depending on your level of access privilege
and on the modules you have installed in your CoreBuilder chassis.
Updating Your
System Software
You can install a new software version from any host that is running FTP
server software.The system software is distributed for both the UNIX and
the MS-DOS platforms.
The following media types are used to distribute compressed files for
software releases:
■
UNIX tar format 3
1
/
2
-inch, double-sided, high-density 1.44 MB diskettes
■
MS-DOS format 3
1
/
2
-inch, double-sided, high-density 1.44 MB diskettes
To install or upgrade your system software, you must:
1 Copy the software from the diskette to your UNIX or MS-DOS computer’s
hard disk.
2 Decompress the software.
3 Load the system software from your computer’s hard disk to flash memory
on the LMM+.
Details for these procedures are provided in the next sections.

Copying System
Software to a
Hard Disk
You can copy system software to a computer that runs either a UNIX or an
MS-DOS operating system.
Copying to the UNIX Platform
The CoreBuilder software for a UNIX system is distributed on six diskettes.
Diskettes #1, #2, #3, #4, and #5 contain the CoreBuilder software. Diskette #6
contains the SNMP MIBs.
To copy the software to a UNIX hard disk, follow these instructions.
If the directory
/usr/lp6000R
does not exist on your computer, create the
directory before proceeding. If your
/usr
directory is full, use a different
directory and substitute the name of the actual directory for /usr in this
and subsequent procedures.
1Insert diskette #1 into the disk drive. These instructions assume drive rfd0.
2Extract the first part of the software file using the following commands:
# cd /usr/lp6000R
# tar xvf /dev/rfd0
3Remove diskette #1 using the following command:
# eject
4Insert diskette #2 into the disk drive and extract the second part of the file
using the following command:
# tar xvf /dev/rfd0
5Remove diskette #2 using the following command:
# eject
6Insert diskette #3 into the disk drive and extract the third part of the file
using the following command:
# tar xvf /dev/rfd0
7Remove diskette #3 using the following command:
# eject
