Installation Summary

This chapter describes the installation procedures for the HP J3245A
AdvanceStack Swit ch 800T (hereafter 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 tran sceivers us ed in t he Switch 80 0T, use cat egory 5,

four-pair , 100 o h m UTP (unshielded twisted-pair) cables. 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.

1

Installation

• For 100Base-FX transceivers used in the Switch 800T, use fiber

optical cables that:
– Are fitted with type SC connectors
– Conform to ISO/IEC 793-2 type B1 and ITU-T G.652 standards

Caution Ensure that the power source circu its are adequate and properly

grounded. That is, ensure that any Switch 800T installation , together wit h
any other devices, does not overload the power circuits, wiring, and over­current protection. To determine the possibility of overloading the supply
circuits, add tog eth er the ampere ratings from the nameplates of all
devices instal led 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”.

) 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 front
panel respond properly.

4. Mount the switch in a rack, on a wall, or on a tabletop.
Hewlett-Packar d sells 19-inch free-standing equi p ment racks. T o o rder 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 (redun dant)
power to keep the switch operatin g in the event of a failure in either a
power circuit or a power supply unit.

6. Connect the Switch 800T to a netwo rk and connect computers and/

or other devices to the switch’s ports.

7. Configure the Switch 800T. The Switch 800T, in its factory defaul t
configuration , operates as a multiport transparen t b ri d ge. You will need
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 emulator connected to th e Consol e RS- 232 port

on the switch either directly or via a modem

• An actual terminal directly connec ted to the Console RS-232 port on

(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 optio ns, you ca n also acce ss the conso le interface via Teln et or use
a network management tool, such as Hewlett-P ack ard’s AdvanceStack
Assistant, for some configuration and monitoring functions.

Mounting
Precautions

■ In a rack or cabinet

■ On a table

■ On a wall

The hardware for mounting the switch is included in the accessory kit
(5063-8544) packed with the switch.

Hewlett-Packar d sells 19-inch free-s t an d in g equ ipment racks. For more
information, contact your HP authorized LAN dealer.

Before mounting the switch, read and follow these mounting precautions:

■ Plan the switch’s location and orientation relative to other devices and

equipment. Also consid er 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-pair cabl es. In the back of the switch, leave
1-1/2 inches ( 3.8cm) of space for the power cord.

■ Ensure that any ins t allation 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 appendi xes at the
back of this manual.

■ Do not install the Switch 800T in an envi ronment where the operating

ambient temperat ure mi ght exceed 55°C (131°F).

■ For proper cooling, make sure the air flow around the sides and back of

the switch is not restricted.

■ If an HP J2962A AdvanceStack Switch 800T Redundant Power Supply is

installed, make sure the air flow around the fan area of the RPS is not
restricted.

You can use one of the following to provid e 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:

Caution If you use a pow er c ord that plugs into the power cord recept ac le

(figure 1- 1 3), do not use the opti onal redu n dant pow er su pp l y ( RPS).
If your installation requires a different p ower cord than the o ne

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 mark is your ass urance that the power cord can

4. Connect a Power Supply

To Use the (Optional) HP J2962A AdvanceStack Redundant
Power Supply (RPS):

Caution Remove the power cord from the Switch 800T before connecting the

(optional) redundant power supply (RPS).

You can use th e optional HP J 2962A Ad vanc eStack R edundant Power Supply

(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 circu it. It also eliminates reliance on a single device power
supply. To connect the RPS to the Switch 800T, it is necessary to first turn

off powe r t o th e sw it c h by re moving th e switch’ s own powe r co rd. Thus, if
you are using the RPS, Hewlett-Packard recommends that you connect the
RPS to the S w itch 800T before connec ting 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.

About the Console In ter face. The console interface enab les you to r econ­figure 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.

The Switch 800T offers two methods of access to the console interface:

■ Console RS-232 (out-of-b and) access:

• Directly connected to the Console RS-232 port, using a serial cable

and a PC running a terminal emul ato r or an actual terminal

• Remotely connected to the Conso le RS -232 port, usi n g mod ems an d

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 limited by setting Manager-level and Operator-level
passwords.

Starting and Ending a Console Session

Starting and Ending a Console Session

Note This manual assumes that either a termi na l d evice is already con f igu red and

connected to your Switch 800T (as described in chapter 1, “I nstallation”) or
that you have already en ab led Telnet access to the switch . (To enable Telnet
access, refer to “Console Features” on page 3-17.)

How To Start a Console Session:

1. Start your PC terminal emulator, terminal, or Telnet session on a remote
terminal device.

Using the Console Interface

2. Do one of the following:

• If you are using Telnet, go to the next step.

• If you are using a PC terminal emulator or a terminal, you should then

see the following p rom pt:

Waiting for speed sense. Press <enter> to continue.

Note: If the console displays a series of random and/or unread-
able characters instead of the above prompt, the Baud Rate
setting for the terminal may be different from that of the console
interface. The switch’s autosensing feature remedies this prob-

lem when you pr e ss a key.

Press [Enter] and go to the next step.

3. The display the n briefly displays a messa ge in d icating the baud rate at
which the s erial inter face (Cons ole RS-232 port) is operating, followe d by
the copyright screen. Do one of the following:

• If a password has been set, the Password prompt appears. Type the

password and press [Enter] to display the Main Menu (figure 2-1).

• If no password has been set, you will see this prompt:

Press any key to continue.

If there is any system-down information to report, the switch displays it
in this step and in the Event Log.

Using Password Security

There are two levels of console access: Manager and Operator. For securit y,
you can set a password on each of these levels.

Leve l Actions Perm it te d

Manager: Access to all console interface areas. This is t he default level. (That is, if a

Manager password has
session, then anyone having access to the console can acc ess any area of
the console interface.)

Operator : Access to the Status and Counter s, Event Lo g, and minima l Configuration

areas for display only.

Using Password Security

Using the Console Interface

To use password security:

1. Set a Manager password (and an Operator password, if applicable for your
system).

2. Exit from the current console session. A Manager password will now be
needed for full access to the conso le.

If you do steps 1 and 2, above, then the next time a console session is started,
the console interface w ill prompt for a password. Assuming that both a
Manager password and an Operator pass word 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 sessio n to end after the speci fie d
period of inactivity, thus giving you added security against unauthorized
console access. (Once a Manager password is set and the console session is
ended, access to the full console interfac e f or any sub sequent sessions
requires the Manager pass word to be enter ed .)

Using Password Secu rity

Note If there is only a Manager password set (with no Operator password), and the

Manager password is not enter ed corr ectly when the console s ession b egins ,
the switch operates on the Operat or level.

If there are both a Manager p assword and an Operator passw ord, 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:

Rebooting the Switch

Rebooting the Switch

Rebooting the switch terminates the current console session and performs a
reset of the operating system. Some of the reasons for performing a reboot
include:

■ Activating certain configuration changes that require a reboot

■ Resetting statistical counters to zero

To Reboot the switch, use the Reboot Switch option in the Main menu. (If
a Manager password has been previously set, Reboot Switch appears o nly
if this password is entered at the beginning of the console session.)

two levels of reset:

■ Hardware re s e t : Momentarily interrupts switch operation, performs a

complete hardware self-test. This also clear s the Event L o g.

■ Configuration reset: This is a drastic action that interrupts switch

operation, clears any passwords, cl ears 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.

■ The time server information (us ed if yo u want the switch to get its time

information from another device operating as a Timep server)

You can manually configure an IP address, subnet mask, and a Gateway IP
address by setting the IP Config parameter to Manual. Or, you can use
Bootp to configure IP for the switch from a Bootp server. In this case you must
also confi gu re your Bootp server accordin gly. If you plan to use Bootp, refer

Virtual LAN ( VLAN) Features

Enables you to create up to eight port-based VLANs. A VLAN is a group of
ports designated by the Switch 800T as belo n ging to the same broadcast
domain. This feature enables you to configure port-based virtual LANs to help
isolate broadcast traffic and increase security. Typically, 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 d efault sta te, VLANs are n ot configu red. All ports belong to th e

same broadcast/multicast domain. This domain is called “DEFAULT_VLAN”
and appears in the “VLAN Names” screen. You can cre ate up to seven add i­tional VLANs by adding new VLAN names, and then assigning one or more
ports to each V LAN. ( The switch accepts a maximum of eight VLANs, includ­ing the d efault VLAN.) Note that each port can be as signed to onl y one VLAN.
DEFAULT_VLAN can be re named, but not delet ed. Any p orts not specific ally
assigned to another VLAN wi ll remain assigned to DEFAULT_VLAN.

Configur ing the Switch

Configurable Features

Note B efore 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.)

Config urable Features

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 colla borative computing, wher e th ere 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-versio n of the Switch 2000) can then be configured to direct the
multicast traffic to only the ports where needed.

Configuring the Switch

In the factory default state (IGMP disabled), the switch forwards all IGMP
traffic. When IGMP is enabled, you can configure the switch to any of the
following states on a per-port basis:

■ Automatic (the defaul t): Causes the switch to int erpret IGMP packets and

to filter IP multicast tr affic 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 th e switch to forward all IGMP and IP multicast

transmissions through the port.

For more information on IGMP and how to configure it, refer to “IP Multicast
(IGMP)” on 7-23.

which management stations receive the traps. An authentication trap is sent
and the Security LED on the front panel of the switch begins flashing if a
management station attempts an unauthorized access. (The ClearLED

command turns off the Security LED—page 6-6.) Check the event lo g to help
determine why the authentication trap was sent. (Refer to chapte r 4 for

Spanning Tree Features

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 Enab led pa rameter to Yes. This ens ures 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 switc h, bridge, or data link failure, STP develops a new spanning tree that
may result in chan ging some ports from th e b lock ing state to the fo rward in g
state.

If VLANs are configured , then yo u can conf igu re STP separately for each
VLAN.

Configur ing the Switch

Configurable Features

Caution Because the switch automatically gives faster links a higher priority, the

default STP parameter setti n gs are usu ally adequate for spanning tre e
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 Concepts”, and examine the IEEE 802.1d st andard.

The switch automatically senses port identity and typ e, and automatically
defines port cost and pri ority for e ach type. The inte rface a llows you to ad just
the Cost and Priority for each port, as well as the global STP parameter values
for the switch.

To configure STP, refer to “Spanning Tree Proto co l (STP)” on page 7-2.

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—broadcast domains—still requires a rout er, ABC func t ions withi n
VLANs and, by using multiple subnets per VLAN (multi-netting), can reduce
or eliminate the need fo r routers within the VLAN.)

Configur ing the Switch

Configurable Features

When enabled, ABC also allows you to set the broadcast limit parameter
(Bcast Limit) in the Port Co nfig urati on screen (figur e 3- 5) for al l ports on

Using SNMP To Monito r and

Using SNMP To Monitor and Manage the
Switch

You can manage the switch via SNMP from a network management station.
(The switch supports SNMP v1 and SNMP v2c, except as noted below for
SNMP v2 Notifications.) If you are using IP, you must either configure the
switch with the appropriate IP address or, if you are using Bootp to configure
the switch, ensure that the Bootp pr oc ess provid es the IP address. (The IPX
address is aut omatic all y configu red.) If mult ip le VLANs ar e configu red, ea ch
VLAN interface shoul d have it s own IP or IPX network address. This chapt er
provides an over view of SNMP manageme nt for th e switch and describes the
configuration process for the various features. For param eter-specific infor­mation, refer to the Help provided in the individual configuration screens.

SNMP Management

SNMP management features on the switch include:

■ Security via con f igu ration of SNMP communities

Manage the Switch

■ Event reporting via SNMP traps and RMON (SNMP v2 Notifications are

not supported at this time.)

■ Managing the switch with a network manageme nt tool such as HP

AdvanceStack Assistant

■ Monitoring data normally associated with the SNMP agent (“Get” opera-

tions). Supported Standard MIBs include:

• Bridge MIB (RFC 1493)

• Etherlike MIB (RFC 1650)

• Ethernet MAU MIB (RFC 1515)

• Interfaces Evolution MIB (RFC 1573)

• Novell Standard IPX MIB (ipx.mib)

• RMON MIB (RFC 1757)—etherstats, events, alarm s, and his t o ry

• SNMP MIB-II (RFC 1213)

The switch SNMP agent also uses certain var iabl es that are includ ed in a

Hewlett-Packard proprietary MIB file you can add to the SNMP database
in your network management tool. You can copy the MIB file from the
compact disk (CD) shipped with the switch, or from following World Wide
Web site:

SNMP Configuration Pr ocess

SNMP Configuration Process

The general steps to confi gu ri n g f or SNMP access to the preced in g featu res
are:

1. From the Main menu, select Configuration.

2. Enable and configure an IP address for the switch, in clu d in g an y n eces­sary gateways. An IPX addr ess is automatical ly configu red. (For more on
configurin g IPX and I P, refer to page 3-7 and page 3-9.)

3. Configure the appropriate SNMP communities. (The “public” community

exists by default and is used by HP’s network management applications.)
(For more on configuring SNMP communities, refer to page 3-13.)

4. Configure the appropriate trap receivers. (For more on configuring trap
receivers , r efer to page 3-15.)

In many networks, manager addresses are not used. In this case, all manage­ment stations usi ng the correct community name may access this device with
the View and Acces s levels t hat have be en set for that comm unity. If you wan t
to restrict acc ess to one or more specific no des, you can enter up to 10 IP and/
or IPX addresses of such nodes into the Manager Address field. Configuring

one or more IP or IPX addresses in the Manager Address field means that
only the network management stations at those addresses are authorized to
use the community name to access the switch.

Using SNMP To Monito r and

Manage the Switch

Caution Deleting the community named “public” disables many network management

functions (such as auto-discovery, traffic monitoring, and threshold setting).
If security for network management is a concern, it is recommended that you
change the write access for t he “public” community to “Restricted ”.

Note SNMP community and trap receive r configu rations are ac tivated w hen saved.

Rebooting the switch is not necessar y unles s you have also configured other
parameters that require rebooting in order to be activated. (For more on when
it is necessary to reboot, refer to “Rebooting the Switch” on page 2-10.)

Figure 6-1. Selecting the Command Prompt

2. Do the following:

• If there are no VLANs (virtual LANs) configured , go to step 3.

• If VLANs are configured, the prompt displays the name of the default,

or first VLAN, then asks you to select the VLAN in which to operate.
Use the Space bar to select the VLAN in which you want to operate,
then press [Enter].

3. The command prompt appears near th e bottom of the sc reen. Th e text in
the prompt matches the System Name parameter. (If there are multiple
VLANs configured, then the text in the prompt matches the name of the
VLAN in which the command prompt is operating.) For example, in the
factory default configuration (no system name or VLANs configured), the
command prompt looks like this:

DEFAULT_CONFIG:

4. Type in the command you want to execute and press [Enter]. For exampl e,
to set the time to 9:55 a.m. you would execute the follow ing co mm an d:
