Preface
Overview of Console Applications
Example of the HP AdvanceStack Switch 800T with Four 100Base-TX Transceivers
installed
When powered-up in the factory default co n f igu r ation, the Switch 800Tautomatically operates as a multiport learning bridge with the following
configuration:
■All ports are enabled and are members of a single broadcast domain
■Spanning tree protocol (STP) 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
This chapter describes the installation procedures for the HP J3245A
AdvanceStack Switch 800T (h er eafter referred to as the Switch 800T).
The following is a summary of those procedures:
1.Site Preparation. Ensure that the cabling infrastructure meets the
network specifications for your intended use of the Switch 800T.
•For 100Base-TX transc eivers used in the Swi tch 800T, us e categor y 5,
four-pair, 100 oh m UTP (unshielded twisted-pair) cabl es. Cable
lengths can be up to 100 meters. For a connection to an end node, use
straight-through cable. For a connection to a hub or a switch, use a
crossover cable.
•For 100Base-FX transcei vers used in the Switch 800T, use fiber
optical cable s that:
–Are fitted with type SC connectors
–Conform to ISO/IEC 793-2 type B1 and ITU-T G.652 standa rds
CautionEnsure that the power source circuits are adequate and properly
grounded. That is, ensure that any Switch 800T installation , together with
any other devices, does not overload the power circuits, wiring, and overcurrent protection. To determine the possibility of overloading the supply
circuits, add together the ampere ratings from the nameplates of all
devices installed o n the same circuits and compare the total with the
rating limits for the supply circuits. For additional information, refer to
appendix B, “Specifications”.

Installation Summary
2.Install transceivers (optional). The Swi t ch 800T is shipped wi th fo u r
HP J3192B AdvanceStack 10 0Base-TX Twis ted-Pair Transceive r Modules
(referred to in this manual as “trans ceiv ers”) already insta lle d.
CautionBecause the Switch 800T can be damaged by installing or removing a
transceiver while powered-up, the ONLY time to install additional
transceivers is before powering up the switch or with the power
disconnected during scheduled down times.
The J3192A
Always use the “B” version (J 3192B
twisted-pair transceiver is not supported in the Switch 800T.
) or any later J3192 transceiver(s).
3.Verify the switch’s operation. This is a simple process of applying
power to the Switc h 800T and ensuring that the LEDs on the switch’s fr ont
panel respond properly.
4.Mount the switch in a rack, o n a wall, or on a tabletop.
Hewlett-Packard sells 19-inch free-standing eq ui p ment racks. To order a
rack, contact your HP-authorized LAN dealer.
5.(Optional) Connect the J2962A HP AdvanceStack Redundant
Power Supply (RPS) instead of using the switch’s own power
supply. This optional power supply can be used instead of the switch’s
main power supply to provide both primary and backup (redunda nt)
power to keep the switch operating in the event of a failure in either a
power circuit or a power supply unit.
6.Connect the Switch 800T to a network and co nnect computers and/
or other devices to the switch’s ports.
7.Configure the Switch 800T. The Switch 800T, in its factory default
configuration, operates as a multiport transparent bridge. You will ne ed
to use the console interface utility to configure the switch for additional
functionality. Initially, this requires one of the following:
•A PC with a terminal emulato r conn ected to the Consol e RS- 232 por t
on the switch either directl y or via a modem
•An actual terminal directly connected to the Consol e RS-232 port on
the switch
1-2
(For examples of terminal emulator configurations, refer to appendix C,
“Sample Console Configurations”. )
After configuring a minimal IP or IPX configuration through one of the
above options, you can also access the console interface via Telnet o r use
a network management tool, such as Hewlett-Pack ar d ’s AdvanceStack
Assistant, for some configuration and monitoring functions.

Installation
1. Install Add-In Transceivers (Optional)
The Switch 800T is shipped with four HP J3192B AdvanceStack 100Base-TX
Twisted-Pair Transceiver Modules already installed. (The switch does not
support use of the “A” version—HP J3192A—o f t his tr an sceiver.) Additional
twisted-pair (UTP) or fiber transceivers must be purchased separately. (You
need a minimum of one transceiver inst alled to connect the switch to your
network, and one additional trans ceiver installed for each connectio n to a
server, hub, switch, or other device.) The Switch 800T is designed to operate
with either of the following two tran sceivers:
CautionTo avoid damage to circuitry in the Switch 800T and transceivers,
always have the power to the Switch 800T turned off while a transceiver is being installed or removed.
For proper cooling and for reduction of electromagnetic emissions, ensure
that a slot cover (provided with your Switch 800T) is installed on any unused
transceiver slot.

information, contact your HP authorized LAN dealer.
Mounting
Precautions
Before mounting the switch, read and follow these mounting precautions:
■Plan the switch’s location and orientation relative to other devices and
equipment. Also consider the cabling that will be attached to the switch
and ports that will be used. In the front of the switch, leave 3 inches
(7.6 cm) of space for twisted-pai r cables. In the back of the switch, leave
1-1/2 inches (3.8cm) of space for the power cord.
■Ensure that any installation of a Switch 800T, together with any other
devices, does not overload the power circuits, wiring, and over-current
protection. To determine the possibility of overloading the supply circuits,
add together the ampere ratings from the nameplates of all devices
installed on the same circuits and compare the total with the rating limits
for the supply circuits.
■Make sure that the power source circuits are properly grounded, then use
the supplied power cord to connect the Switch 800T to the circuit. Refer
to the Safety and Regulatory Statements that follow the appendixes at the
back of this manual.
■Do not install the Switch 800T in an environme n t where the operating
ambient temperature mi gh t exc eed 55°C (131°F).
■For proper cooling, make sure the air flow around the sides and back of
the switch is not restricte d.
■If an HP J2962A AdvanceStack Swit ch 800T Redundant Power Supply is
installed, make sure the air flow around the fan area of the RPS is not
restricted.

4. Connect a Power S upply
4. Connect a Power Supply
The Switch 800T does not have a power switch. It is powered-on when the
power cord is pl ugged i n. Th e swit ch’s power s upply au tomatica ll y adjus ts to
any AC power source between 100-127 volts and 200-240 volts. There are no
voltage range set t in gs to configure.
You can use one of the following to provide power to the Swit ch 800T:
■The power cord provided with the Switch 800T.
OR
■The optional HP J2962A AdvanceStack Redundant Power Supply (RPS).
To Use the Power Cord Provided with the Switch 800T:
CautionIf you use a power c or d that plugs into the power cord receptacle
(figure 1-13), do not use th e opt i onal redu n dant pow er su pp l y ( RPS).
If your installation requ ires a different power cord than the one
supplied with the switch, be sure to use a power cord displaying the
mark of the safety agency that defines the regulations for power cords
in your country. The mar k i s your assurance that the power cord can
be used safely with the switch.
1.Ensure that the switch is properly mounted. (Refer to “3. Mount the
Switch” on page 1-8.)
2.Plug the power c ord into the switch’s pow er co rd receptacle and into an

Installation
To Use the (Optional) HP J2962A AdvanceStack Redundant
Power Supply (RPS):
CautionRemove the power cord from the Switch 800T before connecting the
(optional) redundant power supply (RPS).
You can use the opt ional HP J2962 A Adva nceS tack Red undant Power S upply
(RPS) instead of the Switch 800T’s built-in power supply. This can help ensure
continuous switch operation in the event of a power failure on an individual
power supply circuit. It also eliminates reliance on a single d evice power
supply. To connect the RPS to the Switch 800T, it is necessary to first turn
off powe r to t he switch by removing the switch’s own pow e r co rd. Thus, if
you are using the RPS, Hewlett-Packard recommends that you connect the
RPS to the Sw itch 800T before connecting the switch to your network. Otherwise, you must schedule downtime to connect the RPS. When the RPS is
connected to a Switch 800T and power is applied to the RPS, the RPS LED on
the Switch 800T’s front panel is lit.
NoteFor importan t info rmati on on h ow to i nstal l and connect the (optio nal) HP

Using the Console Interface
Overview
This chapter descri b es the fo llowing features:
■Starting and ending a console session (page 2-2)
■The Main Menu (page 2-4)
■Screen structure and nav igation (page 2-5)
■Using password security (page 2-7)
■Rebooting the switch (page 2-10)
■Resetting the switch (page 2-12)
About the Console Inter face. The console in terface enab les you to reco nfigure the switch and to monitor the switch status and performance. It consists
of a series of management screens accessed through a menu-driven screen
structure that begins at the Main Menu, and is organized as described in this
section.

Using the Console Interface
The Switch 800T offers two methods of access to the console interface:
■Console RS-232 (ou t -o f-band) access:
•Directly connected to the Console RS-232 port, using a serial cable
and a PC running a terminal emulato r or an actual terminal
•Remotely connected to the Console RS-232 port, using modems and
a PC running a terminal emulator or an actual terminal
Refer to chapter 1, “Installation”, for information on making RS-232
hardware connections.
■In-Band access using Telnet from a PC or UNIX station on the network.
This method requires that you first configure an IP address and subnet
mask by using either out-of-band console access or Bootp. The Switch
800T allows one outbound and one inbound Telnet session to be running
simultaneously.
Console access can be lim ited b y setting Manager-level and Operator -level
passwords.

Using Password Security
Using Password Security
There are two levels of console access: Manager and Operator. For security,
you can set a password on each of these leve ls.
Level Action s P er m it te d
Manager:Access to all console interface areas. This is the default level. (Tha t is, if a
Manager password has
session , then anyone having access to the console can access any area of
the console interface.)
Operator:Access to the Status and Counters, Even t Log, and minimal Configuration
areas for display only.
Use of the LOGOUT command.
On the Operator level, the Command Prompt, Set Passwor ds, Download OS,
and Reboot options are not available in the M ain menu.
To use password security:
1.Set a Manager password (and an Operator password, if applicable for your
system).
not
been set prior to starting the current console
Using the Console Interface
2.Exit from the current console session. A Manager password will now be
needed for full access to the console.
If you do steps 1 and 2, above, then the next time a console session is started,
the console interface will prompt for a password. Assuming that both a
Manager password and an Operator password hav e been set, the level of
access to the console interface will be determined by which password is
entered in response to the prompt.
If you set a Manager password, you may also want to configure the
Connection Inactivity Time parameter in the Serial Link configuration
screen (page 3-16 ). This caus es the consol e session to end after the speci fied
period of inactivity, thus giving you added security against unauthorized
console access. (Once a Manager password is set and the console sessi on is
ended, access to the full cons o le in ter f ace for any subsequent sessions
requires the Manager password t o be entered .)
2-7
Using the Console Interface
Using Pas sw ord Security
NoteIf there is only a Manager password set (with no Operator password), and the
Manager password is not entered co rrectly when the co nsole sess ion begin s,
the switch operates on the Operator level.
If there are both a Manager pas sword and an Operator password, but neit her
is entered correctly, access to the console will be denied.
If a Manager password is not set, anyone having access to the console
interface can operate the console with full manager privileges, regardless of
whether an Operator password is set.
Passwords are case-sensitive.
The rest of this section covers how to:
■Set a Password
■Delete a Password
■Recover from a Lost Password
To set Manager and Operator pass w ords:.
Using the Console Interface
1.From the Main menu select Set Passwords. This screen appears:

Resetting the Switch
Resetting requ ires physical access to th e front of the Switch 800T. There are
two levels of reset:
■Hardware reset: Momentarily interrupts switch operation, performs a
complete hardware self- t est. This also clears the Event Log.
■Configuration reset: This is a drastic action that inte rru p t s switch
operation, clears any passwords, clears the event log, performs a complete self-test, and reboots the switch in its factory default configuration.
You should consider performing a configuration reset only if you want all
configurable parameters reset to the factory default values.

domain. This feature enables you to configure port-based virtual LANs to help
isolate broadcas t traffic and increase securit y. T yp ically, if VLANs are used,
all ports carrying traffic for a particular subnet address should be configured
to the same VLAN. For more on when, why, and how to use VLANs, refer to
“Virtual LANS (VLANs)” on page 7-14.
In the factory defaul t sta te, VLANs are not configur ed. All ports b elong to the
same broadcast/multicast domain. This domain is called “DEFAULT_VLAN”
and appears in the “VLAN Names” screen. You can create up to seven additional VLANs by adding new VLAN names, and then assigning one or more
ports to each VLAN. (The switch accepts a maximum of eigh t VLANs, including the defau lt V LAN.) Note that each port can be as signed to onl y one VLAN.
DEFAULT_VLAN can be rena med, but not delet ed. Any ports not specific ally
assigned to another VLAN wi ll remain assigned to DEFAULT_VLAN.
NoteBefor e you delete a VLAN, you must re-assign its ports to another VLAN.
When VLANs are used, and are managed from an SNMP workstation, you
should configure the IPX and/or IP services for each VLAN. (Refer to pages
3-7 and 3-9.)
Spanning T ree protocol (STP), ABC, IGMP, and some o ther features o perate

IP Multicast (IGMP) Service Features—Multimedia
Traffic Control
The IGMP (Internet Group Management Protocol) feature helps to reduce
network congestion and improve security by reducing unnecessary multicast
traffic on a per-port basis. This is useful in multimedia applications such as
LAN TV, desktop conferencing, and collaborative comput in g, where there is
multipoint communication; that is, communication from one to many hosts,
or communication originating from many hosts and destined for many other
hosts. In such multipoint applications, IGMP will be configured on the hosts,
and multicast traffic will be generated by one or more servers (inside or
outside of the local network). Switches in the network (such as the Switch
800T or the B-version of the Switch 2000) can the n be configured to direct the
multicast traffic to only the ports where needed.
In the factory default state (IGMP disabled), the swit ch forwar ds all IGMP
traffic. When IGMP is enable d, you can conf igu re the switch to any of the
following states on a per-port basis:
■Automatic (the default) : Causes the switch to interpret IGMP packets and
to filter IP multicast traffi c based on the IGMP packet information for that
port.
■Blocking: Causes the switch to drop all IGMP transmissions received and
block all outgoing IP Multicast packets for that port.
■Forwarding: Causes the switch to forward all IGMP and IP multicast
transmissions through the port.

Spanning Tree Featu r es
Enables you to activate the IEEE 802.1d Spanning Tree Protocol (STP) and to
adjust spanning tree parameters. In the factory default, STP is off. Thus, if
there are any redundant paths (loops) between nodes in your network, you
should set the Spanning T ree Enabl ed para meter to Yes. Thi s ensu res that al l
redundant ports (those providing backup parallel connections) are in a blocking state and not used to forward data. In the event of a topology change such
as a switch, b ridge, or data link fai lure, STP d evelops a new spanning tr ee that
may result in changing some ports from the blocking s tate to the forwarding
state.
If VLANs are configured, then yo u can conf igu r e S TP separ ately for each
VLAN.
CautionBecause the switch automatically gives faster links a higher priority, the
default STP parameter settin gs are usually adequate for spanning tree
operation. Because incorrect STP settings can adversely affect network
performance, you should avoid making changes without having a strong
understanding of how STP operates. For more on STP, refer to chapter 7,
“Advanced Concep t s”, and examine the IEEE 802.1d standard.
The switch automatical ly senses port identity and type, and automatically
defines port cost and prio rity for each type. The inte rface allo ws you to adju st

Automatic Broadcast Control (ABC) Features—Layer 3
Switching
ABC reduces the amount of IP and/or IPX broadcast traffic on a network by
enabling the switch to serve as a proxy for the ultimate destination of broadcast IP ARP and RIP packets, and IPX NSQ, and RIP or SAP packets. This
reduces the number of ports over which IP and/or IPX broadcasts are sent,
increases the amount of network bandwidth available for other purposes, and
can reduce the need for routers withi n a network. These factors can lower
costs and reduce latency in the network. (While communication between
VLANs—broad cast domains—st ill requires a router, ABC functions within
VLANs and, by using multiple subnets per VLAN (multi-netting), can reduce
or eliminate the need for ro uters within the VLAN.)
When enabled, ABC also allo ws you to set the broadcast limit parameter
(Bcast Limit) in the Port Con fig uratio n screen ( figur e 3-5) for al l ports o n
