Preface
Preface
Use of This Guide and Other Switch 2000
Documentation
This guide describes how to install the B-version of the Switch 2000 (HP
J3100B) in your network and use the console interface for the
HP AdvanceStack Switch 2000 (hereafter referred to as the “Switch 2000”).
Operating
Differences This manual describes features of the B-version of the Hewlett-Packard
Switch2000 (HP J3100B). In some cases, such as the Spanning TreeProtocol
(operating within VLANs)and port trunking capabilities, there are significant
operating differences between the A-version of the Switch 2000 (HP J3100A)
and the B-version. For information on the features available in the A-version,
refer to the manuals shipped with that product.
Important! Before installing or removing an interface module (or installing
or removing a transceiver used with a module), refer to the specific module
documentation describing these procedures.
■If you need information on specific parameters in the console interface,
refer to the online help provided in the interface.
■If you need further information on Hewlett-Packard switch technology,
refer to the HP AdvanceStack Products CD shipped with your Switch
2000.

Preface
Overview of Console Applications
Figure 1. Example of the HP AdvanceStack Switch 2000 with Optional Modules
and Transceivers installed
When powered-up in the factory default configuration, the Switch 2000
automatically operates as a multiport learning bridge with the following
configuration:
■All installed ports are enabled and are members of a single broadcast
domain
■Spanning tree protocol (STP) is disabled
The console interface provides the following capabilities for use when you
want to move beyond this basic level of operation:
■Monitoring system performance and status
■Customizing the system configuration for improved performance and
unique system requirements
■Enabling network management (SNMP) access
■Setting passwords to help protect system security
■Downloading system software updates
■Troubleshooting

Installing the Switch
Installation Summary
This chapter describes the installation procedures for the HP J3100B
AdvanceStack Switch 2000 (hereafter referred to as the Switch 2000).
The following is a summary of those procedures:
1. Installinterfacemodules andtransceivers(optional).Thebesttime
to install Switch 2000 interface modules and their related transceivers is
prior to powering up the switch or during scheduled down times. Note
that,becausetheSwitch2000allowsmodulechanges(“hotswaps”)while
operating,youcanmakehardwarechangesoncetheswitchisinuse.That
is, you can replace one module with another module of the same type
without needing to reboot the switch. Similarly, you can install a module
in anunused slotwithoutneeding to reboot the switch. (An “unused slot”
isone thathasnotbeenusedsincethelasttimetheswitchwasrebooted.)
However,itisnecessarytoremoveaparticularinterfacemodulefromthe
Switch 2000 before adding, removing, or changing a transceiver in that
module.Incaseswhereonemoduleisexchangedforanotherofadifferent
type, it is necessary to reboot or reset the switch. This procedure is
described later in this chapter and also in the installation guides for the
various interface modules that are compatible with the Switch 2000.
2. Install the optional redundant power supply (RPS). This optional
power supply (HP J3136A AdvanceStack Switch 2000 Redundant Power
Supply)sharesthepowerrequirementloadwiththeswitch’smainpower
supply, and will keep the switch operating in the unlikely event that the
main power supply fails.
3. Verify the switch’s operation. This is a simple process of applying
powertotheSwitch2000andensuringthattheLEDsontheswitch’sfront
panel respond properly.
4. Mount the switch in a rack or place it on a tabletop.
Hewlett-Packard sells 19-inch free-standing equipmentracks. To ordera
rack, contact your HP-authorized LAN dealer.

cabinet designed for this product. The Switch 2000 weighs a minimum
of 17.3 lbs (7.86 kilos) with no interface modules or redundant power
supply installed. Rack or cabinet mounting should be done by two
people. If the rack or cabinet is empty, install the Switch 2000 at the
bottom; if not, install the switch as close to the bottom as possible.
(If a lightweight device is already installed at the bottom, you may
want to remove it, install the Switch 2000 at the bottom, then reinstall
the lightweight device above the Switch 2000.) If the Switch 2000 is
mounted high, the rack or cabinet may become unstable and possibly
fall over.
5. Connect the Switch 2000 toa network and connect computers and/
or other devices to the switch’s ports.
6. Configure the Switch 2000. The Switch 2000, in its factory default
configuration, operates as a multiport transparent bridge. You will need
to use the console interface to configure the switch for additional func-
tionality. Initially, this requires one of the following:
• A PCwith a terminal emulator connected tothe Console RS-232 port
on the switch either directly or via a modem
• An actual terminal directly connected to the Console RS-232 port on
the switch
(For examples of terminal emulator configurations, refer to appendix C,
“Sample Console Configurations”.)
7. AfterreceivingaminimalIPorIPXconfigurationthroughoneoftheabove
options, you can also access the console interface via Telnet or use a
network management tool for some configuration and monitoring func-
tions.

1. Install Add-In Modules (Optional)
To begin operating in your network, the Switch 2000 needs at least one
interface module. Ifyou needto install amodule, refer tothe instructions you
received with the module(s) you plan to use. Note that you must install any
optional transceivers in a module before installing the module in the Switch
2000, or remove the module from the switch before installing an optional
transceiver. (Refer to the documentation for the specific module.) For exam-
ple, the HP J3102A AdvanceStack Switch 2000 4-Port 10Base-T module illus-
trated below is shown with the optional HP J2608A ThinLAN transceiver
installed. (Transceivers must be purchased separately.)
Caution If you will be installing or removing a module while the switch is operating,
refer to the documentation you received with the module for important
information,includingany“readme”fileonthediskshippedwiththe module.
Also, refer to the module documentation if you will be installing or removing
a transceiver from a module in an operating Switch 2000.

2. Install the Redundant Power Supply
(Optional)
Caution Disconnect the power supply from the Switch 2000 before installing the
redundant power supply (RPS). Otherwise, damage to the switch’s
components could occur.
Note For important information on how to install the HP J3136A AdvanceStack
Switch 2000 Redundant Power Supply (RPS) in the Switch 2000, refer to
the documentation provided with the RPS.
TheoptionalHPJ3136AAdvanceStackSwitch2000RedundantPowerSupply
(RPS) shares the power load with the Switch 2000’s main power supply. It is
recommendedthat,ifpossible,youinstalltheRPSbeforebeginningtousethe

The RPS connects to the back of the Switch 2000. Thus, if you are going to
install an RPS, it may be more convenient to install it before installing the
Switch 2000 into a rack or other location. Inspect your installation site and
identify whether the switch’s back panel will be accessible.

This process verifies that the Switch 2000 is operating properly.
Verify the Switch Hardware
1. Connect the supplied power cord to the switch’s power receptacle.
Figure 1-3. Back Panelof the Switch 2000
2. Plug the power cord into a properly grounded electrical outlet.
Note Neither the Switch 2000 nor the RPS has a power switch.The Switch 2000 is
powered on when the power cord for either the switch itself or an installed
RPS is plugged into a power source.
If yourinstallation requires adifferent power cord than theone supplied with
the switch, be sure to use a power cord displaying the mark of the safety
agencythatdefinestheregulationsforpowercordsinyourcountry.Themark
is your assurance that the power cord can be used safely with the switch.
3. Check the LEDs on the switch’s front panel.

When theswitch is powered on, it performs a self-diagnostic test.During
the test, the following occurs:
• All LEDs turn on momentarily.
• The Power LED remains on; the Fault LED turns on.
• The RPS LED turns on if an RPS is connected and supplying power.
• The Self-test and Fault LEDs remain on for less than one minute.
When the self-test completes successfully, the following eventsoccur:
• The power LEDand, if anRPS is connected,the RPS LED,remain on.
• The self-test and Fault LEDs turn off.
Note IfanyFaultLEDisflashing,theSwitch2000hasencounteredaproblem.Refer
to chapter 9, “Troubleshooting”.
4. After the switch has passed its self-test, disconnect the power cord from
the switch and proceed with the mounting instructions.
Note If the switch’s permanent location makes it difficult to access the Console
