Overview
Caution TheHPJ3108AFDDIModuleisdesignatedasamodulerequiring“high
power”. Installing more than two high-power modules in the HP
J3100A Switch 2000 may exceed the switch’s power capabilities and
is not supported.
Ifnecessary,youcan“hot-swap”oneFDDIModuleforanother;thatis,replace
one module with another of the same type without rebooting the switch.
However, if you replace one moduletype with a different module type (such
as replacing an Ethernet Module with an FDDI Module), you must reboot the
switch after making the replacement.

Downloading Software
Note The earliest version of OS software files supporting the FDDI Module in the
Switch 2000 is A_02_01.swi and A_02_01.fdd. The version numbers of
theFDDIModuleOSsoftwareandtheSwitch2000OSsoftwareshouldmatch.
For more on this topic, refer to “FDDI Module OS Version” on page 25.
ObservethefollowingwhendownloadingtheOSsoftwaretotheSwitch2000:
■filename.swi and filename.fdd must be in the same directory
■filename must be the same for both files (that is, the files must be
the.swi and.fdd file pair from the disk or from the self-extracting file
j3100a.exe mentioned on page 5.
For the above reasons, avoid placing the filename.swi and
filename.fdd in separate directories, and avoid renaming them.
Note The latest version of the Switch 2000 OS supports all Switch 2000 Modules
currently available. If you are installing more than one type of Switch 2000
moduleand/orif itis necessarytodownloadanewversionoftheSwitch2000
OS, use the latest version available. To support the FDDI Module, use OS
versionA.02.01orlater.TheSwitch2000Ethernetand100VGModulesoperate
with any version of Switch 2000 OS software. For more on software compat-
ibility, see the readme.txt fileincluded onthe disk andin the compressed,
self-extracting j3100a.exe file from the electronicsources mentioned on
page 3.

How To Download the OS
Use this procedure if you need to download a new OS version to your Switch
2000 and the FDDI Module. The procedure describes how to use a personal
computer (PC) to download the OS. (If you are using a UNIX workstation,
refer to the Note on page 6.) The files used in this procedure are described
under “Software Sources and Content” on page 3.
1. Do one of the following:
• IfthesourceofyouOSfilesisthediskshippedwiththeFDDIModule,
copy the files from the disk into the DOS directory you will use for
downloading to the switch. Then go to step 2.
• Ifthe sourceofyour OS files is theself-extracting j3100a.exe file
from an electronic source (see “Software Sources and Content” on
page 3):
i. Copy the j3100.exe file into the DOS directory you will use
for downloading to the switch. (If youare using a UNIX worksta-
tion, refer to the Note on page 6.)
ii. Run the file to decompress and extract its contents.
2. Download the software upgrade by using one of the following methods:
•TFTP download using a TFTP server and the Download OS
option in the Switch 2000 console interface: This is the recom-
mended download method if you have TFTP server access to the
Switch 2000. Refer to the instructions in appendix A, “Downloading
anOperating System”, in theConsole User’sGuideyou received with
your Switch 2000. For this option, use the form
filename.swi
for the Remote File Name parameter. (The filename.fdd file
will automatically be used if an FDDI Module is already installed in
the Switch 2000.)
•Switch update utility: Refer to the instructions in the
readme.txt file provided with the update utility.
3. Ifyou areperforming afirst-timeinstallation ofan FDDI Module,go on to
“Installing the Module in an Unused Slot” on page 7.
