Installation

Prepare the network.

Prepare the network.

1. Complete the network plan. Include network maps and the location
of power sources, computers, data-link equipment, hubs or
repeaters, bridges, other routers, and cabling (and cabling types and
length). Verify the design limits for the cable lengths and the number
of repeaters and nodes in your network.

It is recommended that separate maps be used for each routing
service. The network maps should show:

• The connections between each network device.

• The type of cable used for each connection.

• Network layer addresses where applicable.

• Other information that will need to be configured on the devices,

such as DTE/DCE designations.

2. Install all LAN and WAN links. Verify the LAN cabling. Verify that
WAN-link-terminating equipment is operational. Verify with your
WAN-link-service provider that the WAN link is operating correctly.

3. You need a console to verify and configure the router initially. The
console must be an ANSI or VT100 terminal or a PC running an ANSI
or VT100 terminal emulator. If the console is located at a remote
location, you also need a modem at the console and a modem at the
router for connecting the console to the router. Installation of the
console is included later in this installation procedure.

Installation

Mount the router.

Mount the router.

Before mounting the router, make sure the router’s power cord is
correct for your country’s ac power receptacle. Do not attach the power
cord yet.

Rack or Cabinet Mounting

Warning The rack or cabinet should be adequately secured to prevent it

from becoming unstable and/or falling over.

1. Remove the protective film from the top and front of the router.

2. Using a Phillips (cross-head) screwdriver, remove the top and
bottom screws from the front of one side of the router (see figure
1-1). (Save these screws in case you later want to remove the router
from the rack or cabinet and mount it on a table instead.)

Figure 1-1. Screw Removal

1-5

Installation

Mount the router.

3. Position one of the two mounting brackets over the holes as shown
in figure 1-2. The edge of the bracket with the large hole in the center
should face the router, and the other bracket edge should face front.

Figure 1-2. Bracket Position

4. Using a Phillips (cross-head) screwdriver, secure the bracket to the
router with two 10-mm #M4 screws.

5. Repeat steps 2–4 to attach a bracket to the other side of the router.

Warning The router weighs about 36 pounds (with no interface cards and

one power supply installed) . If the rack or cabinet is empty,
install the router at the bottom; if not, install the router 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
router at the bottom, then reinstall that device above the
router.) If the router is mounted high, the rack or cabinet may
become unstable and possibly fall over.

Note

router on a table near the power source.

Installation

Install interface card(s).

Install interface card(s).

You can install any of the optional interface cards into any of the four
available chassis slots (2–5). (The routing engine must remain installed
in slot 1.)

Notes The following installation procedure describes how to install an inter-

face card in an empty slot. If you are installing an interface card in place
of one already installed in a slot, refer to “Replacing an Interface Card
(System Online)” (page 3-21) or “Replacing the Routing Engine or an
Interface Card (System Offline)” (page 3-27).

This installation procedure is applicable to any of the interface cards.
For installation procedures specific to a particular interface card, refer
to the documentation provided with it.

All slots must be filled, either with card blanks or with interface cards—
you should not use the router with a slot open.

1. Connect a grounding wrist strap to your wrist and to the back of the
router.

2. Press down slightly on the insides of both locks on the card bezel
(see figure 1-6), then swing them outward until the bezel disengages
(see figure 1-5).

Note If you have installed a new 4-Port Ethernet/802.3 Interface card, each of

its four ports contains a preinstalled internal ThinLAN transceiver. You
can replace any of these transceivers with another transceiver, such as
for twisted-pair or fiber-optic cabling, or with an AUI port module,
which lets you connect external transceivers such as for ThickLAN
cabling. Instructions for replacing the transceivers in the 4-Port
Ethernet/802.3 Interface card are provided in the 4-Port Ethernet/802.3
Interface Installation Guide.

Installation

Connect a console.

Connect a console.

You must connect a console to the router in order to verify and
configure it.

Connecting a Local Console

1. Use the supplied console cable (or one of the other options
described in appendix A, “Cables and Adapters”) to connect the
router’s console port (located on the routing engine) to an ANSI or
VT100 terminal, or to a PC emulating an ANSI or VT100 terminal.

2. Start up and configure the terminal or (if using a PC) the terminal
emulation program for the following:

• ANSI or VT100

• 1 stop bit

• 8 bits/character

• Xon/Xoff handshaking

• No parity

• Baud rate of 38400, 19200, 9600, 4800, 2400, 1200, or 300

• Screen size of 24 lines

• If using Microsoft® Windows Terminal:

– Cursor: Underline
– Show Scroll Bars: unchecked

1-13

Installation

Connect a console.

Connecting a Remote Console

1. Use the supplied console cable and modem adapter (or one of the
other options described in appendix A, “Cables and Adapters”) to
connect the router’s console port (located on the routing engine) to a
full-duplex, asynchronous (character-mode) modem. (For supported
modems and their configuration requirements, see appendix B,
“Modem Configuration.”)

2. At the remote site, connect an ANSI or VT100 terminal, or a PC
emulating an ANSI or VT100 terminal, to the remote modem. Then
establish the link between the terminal’s modem and the router’s
modem (for information on doing this, refer to the documentation
for the terminal-emulation or communications software used at the
remote terminal or PC).

3. Start up and configure the terminal for the following:

• ANSI or VT100

• 1 stop bit

• 8 bits/character

• Xon/Xoff handshaking

• No parity

• Baud rate of 9600, 4800, 2400, 1200, or 300

1-14

Installation

Connect network cables.

Connect network cables.

With the power still off (you’ll switch it on in the procedure “Plug in and
verify router hardware” on page 1-18), connect the network cables as de­scribed in the documentation for the interface card(s). You should also
make sure that all network equipment and links are ready.

Caution Static discharge may damage equipment. Do not touch the router

connector pins or the cable connector pins.

Note For most interface cards (excluding, for example, the HP J2437A 4-Port

Token Ring Interface), if any port has no network attached, the port’s
Net Fail LED is lit after the router starts. To avoid unnecessary event log
messages, remember to disable that port when you configure the router.
For information on interpreting the Net Fail LED and other LED error
indications, refer to “Interpreting LED Error Patterns,” page 3-3.

To help keep the network cables orderly—and out of the way when inter­face cards are being removed or installed—arrange the cables over the
bars at the right of the router.

These cable-management bars have slots in them that you can use for
tie-wrapping the network cables. Included with each interface card is a
tie-wrap that you can use to wrap the cables and then attach the bundle
to the cable management bar, as shown in figure 1-10.

Installation

Connect network cables.

Some cables (such as WAN cables) will not fit inside the cable manage­ment bars. You can use the tie-wraps to bundle the extra cables and
hang them on the outside of the bar.

1-16

Installation

Plug in and verify router hardware.

Plug in and verify router hardware.

Note If you will be installing a second power supply, it may be more conven-

ient to do so now; however, you can also install it later (without switch­ing off the first power supply). For information about installing a second
power supply, refer to the documentation accompanying the HP J2446A
Redundant Power Supply.

The router automatically adapts to the correct ac voltage range for your
power source.

1. Plug a power cord into the power socket on the back of the router
nearest the side (the socket labeled “Factory-installed power
supply”).

2. Plug the other end of the power cord into an ac power source.

3. Open the front door on the router, switch the power supply on by
pressing the top of the switch (marked with “
(While the power supply is connected to a power source and is
switched on, the LED on the power switch is lit.)

The router’s self-test begins when the power is switched on. It can
continue for 15–35 seconds, depending on how many interface cards are
installed. During the test, the Status LED for the router is orange and the
Self-test LED for the routing engine (the second LED in the first row) is
green.

several times does not establish the console connection, refer to chapter
3, “Troubleshooting.”

1-19

Installation

Configure and boot the router.

Configure and boot the router.

Configuring the router assigns values to the parameters that control its
networking operation. The router creates a set of default values in the
configuration the first time it is booted. This default state allows the
router to function minimally as a remote bridge when connected to
LANs and WANs. However, interconnection and routing in your network
may require that you change additional configuration parameters.
Hewlett-Packard recommends that you use the Quick Configuration
utility to enter as many of these additional values as as you need. In
some cases, using Quick Configuration may be all that you need to do.
Or you can then use other configuration tools, such as the Configuration
Editor, to enter the other values that may be needed or desirable.

You have the following configuration options:

Quick Configuration creates or changes the configuration from a
single screen that presents the most commonly used router parame­ters. You can use this tool for a “getting started” configuration either
for the initial installation or after using the Reset and Clear buttons
to set the router to its default configuration. (Refer to “Reset, Clear,
and Diag Buttons” on page 2-9.) You can also use this tool to view
and/or change an existing configuration.

Starting from the Main menu (see figure 1-14), press [6] to select
“Quick Configuration.” Follow the prompts on the screen and the
Help presented at the bottom of the screen.

For details on using Quick Configuration, saving your changes, boot­ing the router, and then exiting Quick Configuration, refer to the
User’s Guide. Quick Configuration includes an option for booting the
router before exiting:

• You can answer yes to the question about booting if your network

map specifies no additional parameters. (If you know your net­work requires further configuration before operating, do not boot
within Quick Configuration; instead, use the Configuration Editor
to do the remaining configuration and boot the router. You can
use a “hotkey” to jump to the Configuration Editor from Quick
Configuration; refer to “How to use the ’HotKeys’” in the User’s
Guide.) Proceed to the steps for setting the time, setting pass­words, and verifying the installation, starting on page 1-26.

Installation

Date and Time

Figure 1-14. Main Menu Screen

Configuration Editor can be used after using Quick Configuration
if your network design calls for such features as spanning tree
bridging, static routes, or filtering, or if you have other requirements
for interoperating with other devices. The Configuration Editor
presents a hierarchy of menus and screens that include all
parameters available for customizing and integrating the router into
your network (including the subset of parameters you can access
through Quick Configuration).

At the Main menu (see figure 1-14), press [3] to select “Configuration
Editor.”

• For details on using the Configuration Editor, saving your

changes, and exiting, refer to the User’s Guide. After exiting, you
will return to the Main menu.

• Then you will boot the router using the procedure described at

the end of this list (page 1-23).

1-21

Installation

Configure and boot the router.

You could use Quick Configuration to create a minimal initial
configuration and boot the router, and then you would be able to
determine in the verification steps in the last section of this
procedure whether you need to configure more parameters to
further customize and fully integrate the router into your network. If
so, access the the Configuration Editor from the Main menu (option

3), then return to the booting steps below and verify the configura­tion again.

After using Quick Configuration to set the router’s network addres­ses, such as the IP address and subnet mask, you can complete a
fully customized configuration file using HP OpenView Interconnect
Manager (or another source of a complete configuration file that fits
the particular router model being installed) and transfer the file to
the router.

For details on HP OpenView Interconnect Manager, refer to the
product’s documentation. The router’s User’s Guide includes
instructions for transferring configuration files.

Another option is to use only the Configuration Editor, instead of
Quick Configuration, to configure the router or to modify an existing
configuration.

Note If you later replace an interface card with a different type of interface

card (for example, if you replace an Ethernet/802.3 card with a token
ring card), or if you later install a card in a slot that formerly was empty,
you must specify the new card for that slot in the configuration.

Booting the Router

If you have not booted the router as part of Quick Configuration, or if
you have made and saved further changes using Configuration Editor,
use the following procedure to boot the router when you are ready to
implement the configuration changes.

1. Starting from the Main menu (see figure 1-14), press [2] to select
“Network Control Language Interpreter” (NCL). You will then see the
NCL prompt. This prompt matches the current system name. For
example, if the system name is DEFAULT_CONFIG, then the NCL
prompt appears as shown in figure 1-15.

NCL Prompt

Installation

Configure and boot the router.

Figure 1-15. Default NCL Pr ompt

2. Boot the router (with your new configuration) by typing boot at the
NCL prompt and pressing [Return], as follows:

DEFAULT_CONFIG: boot [Return]

3. If your router does not have a manager password, skip to the next
step. If the router has a previously set manager password, you must
enter the password before booting can proceed. In this case, you are
prompted to enter the password:

Enter current manager password:

Type your manager password and press [Return].
(If you’ve forgotten the password and need to clear it, refer to

“Clearing the Passwords: The Clear Button”, page 2-11.)

4. The following message prompts you to verify that you want to boot
the router:

Do you want to reboot the system? [y/n]

Press [Y] to proceed with booting.

1-23

Installation

Configure and boot the router.

Press any key to continue

(Optional) Set the correct time and date.

Each time you power up your router, it starts with a default time and
date that differs from the actual time and date. Whether you set the
correct time and date or not depends on how you want the correct time
and date to be maintained in your network. When the time and date in
one router is used as the source for time and date in another router, this
control is termed the “Time Protocol service.”

1. Identify the Time Protocol usage for your router and determine
whether to set the date and time:

If the router will operate as a: Set date and time?

Installation

Set the correct time and date.

Client of Time Protocol service
Server of Time Protocol service
Both client and server of Time Protocol service
Neither client nor server of Time Protocol service

*

The router designated as “server only” provides the Time Protocol service. If no
router is designated “server only,” then a client/server router should provide the Time
Protocol service.

No
Yes
No *
Yes

2. If you determine a need to set the time and date, use NCL’s Time
command. (If you do not need to set the time and date, proceed with
the subsequent procedures for setting passwords and verifying the
installation, starting on page 1-28.)

At the Main menu (see figure 1-14), press [2] to select “Network Con­trol Language Interpreter.” The NCL prompt—DEFAULT_CONFIG:
or another system name you have configured—then appears at the
bottom of the screen, as shown in figure 1-17.

Set manager and user passwords.

(Optional) Set manager and user passwords.

Passwords are optional. If no password is set, anyone can use the
console to access the router for viewing, booting, changing the configu­ration, resetting statistics or variables, and using various commands.
Two passwords, a user and manager password, can be set to control
access to two levels of functions:

User password: allows viewing the statistics, event log, MIB
variables, and configuration settings.

Manager password: allows access to the following system
management tasks:

• assigning a user password

• saving a modified configuration

• booting the router

• resetting statistics or MIB variables

• enabling or disabling services

• downloading a configuration

• changing a password

• changing the date and time

• using the Fget, Fput, Ping, and Test commands

• all the functions allowed for the user password

Installation

With both passwords set, the password entered by the user when
beginning the console session controls the level of access allowed
during that session.

1-27

Installation

Set manager and user passwords.

1. At the Main menu (see figure 1-14), press [2] to select “Network Con­trol Language Interpreter.” The NCL prompt—DEFAULT_CONFIG:

4. To set the user password, repeat steps 2 and 3, substituting the user
password for the manager password in step 3.

Installation

Verify router initialization and configurat ion.

Verify router initialization and
configuration.

Earlier in the installation procedure it is normal to verify proper router
hardware operation. (See “Plug in and verify router hardware.” on page
1-18.) At this point in the procedure, after you have configured and
booted the router, you should verify that the router has initialized
properly for your intended application. You are checking two conditions
in the steps below:

Verify that the network links are operational.

Verify that all networks can be reached by the router.

You can save steps by operating from the Network Control Language
Interpreter (NCL). Select NCL from the Main menu.

Access to NCL

Figure 1-19. NCL Access fr om the Ma in Menu

Note For further details on the procedures in this section, refer to the

Operator’s Reference.

1-29

Installation

Verify router initialization and configurat ion.

Examine the event log.

Among the events posted to the event log are those which indicate the
success or failure of the configuration and initialization. Events are
occurrences such as enabling circuits and services, changes in spanning
tree states, and error conditions. Each event is labeled with the date,
time, severity, and a mnemonic for the software resource that generated
the message.

1. Access the event log.
You can see the most recent event in the second line of the console

screen. However, checking events is easier if you display and interac­tively scroll around the entire log. One way to access the interactive
log is to select “Event Log” from the Main menu. The second way is
to use NCL’s Logi command, which is more convenient if you will be
working in NCL more frequently than the Main menu. Upon entering
the event log, you will see the first event for the most recent reboot
at the top of the display. To navigate among the events displayed, use
the following control keys. You can also see new events added to the
end of the list.

[Return] Advance display by one page
[P] Roll back display by one page

[v] Advance display by one event
[^] Roll back display by one event
[>] Display last page (newest events)

[C] Display first page of events for most recent reboot
[H] Display help for event log (including more control keys)

[<] Exit from event log

Refer to chapter 5 of the User’s Guide for more key options and
other information about display control keys, a full explanation of
the parts of an event line, the severity ratings, the number and range
of events kept in the log, and the meaning of each event message.

2. In the event log, verify that the circuits and services that you
configured are being enabled. The events being listed in the event log
should be consistent with information recorded on the network plan
and maps.

1-30

Installation

Verify router initialization and configurat ion.

3. Verify that no warning, major, or fatal events have occurred.

Examine the statistics screens.

1. Access the statistics screens by using NCL’s Stats command or by
selecting Statistics Screen menu from the Main menu. A menu of
statistics screens is presented.

Figure 1-20. Example of the Stati st ics Scre en Menu

For more information on the statistics screens, refer to chapter 6 of
the User’s Guide.

Note The Statistics Screen Menu list the statistics only for those services that

have been configured.

2. Select and examine the Circuit Statistics screen. Verify that error-free
data is being exchanged over enabled circuits. Match the circuit
names with those on the network maps.

1-31

Installation

Verify router initialization and configurat ion.

3. Select and examine the individual statistics screen for each routing
and bridging service configured on the router. Verify that the config­ured services are exchanging frames or packets as expected. The
information listed should match the information on the network
maps. The statistics should reflect the circuit groups, network
interfaces, and traffic patterns expected for the router configuration
and the devices attached to the network.

The following service statistics screens are available:

Bridge Statistics This screen summarizes bridge traffic volume for
each circuit group. It shows the number of frames that were received,
forwarded, flooded, and dropped. The bridge service must be configured
for this screen to be available.

DoD IP Router Statistics This screen provides summary data for
each IP network interface. The interfaces are identified by their IP
addresses. The screen shows the number of IP datagrams received,
forwarded, delivered to upper-layer protocols, and dropped. The DoD
Internet (IP) routing service must be configured for this screen to be
available.

DECnet Router Statistics This screen summarizes DECnet traffic
volume for each circuit group. It shows the number of data packets
received, forwarded, and dropped. The statistics do not represent traffic
generated by DECnet routing layer control messages, such as Hello and
routing messages. The DECnet routing service must be configured for
this screen to be available.

IPX Router Statistics This screen provides summary data for each
IPX network interface. The interfaces are identified by the IPX network
numbers of the networks they are connected to. It shows the number of
datagrams received, forwarded, delivered to upper-layer protocols, and
dropped. The IPX routing service must be configured for this screen to
be available.

XNS Router Statistics This screen provides summary data for each
XNS network interface. The interfaces are identified by the XNS
network numbers of the networks they are connected to. The screen
shows the number of XNS datagrams received, forwarded, delivered to
an upper layer protocol, and dropped. The XNS routing service must be
configured for this screen to be available.

1-32

Installation

Verify router initialization and configurat ion.

AppleTalk Router Statistics This screen summarizes AppleTalk
traffic volume for each circuit group. It shows the number of packets
received, forwarded, and dropped. The AppleTalk routing service must
be configured for this screen to be available.

1-33

Installation

Verify router initialization and configurat ion.

Examine the bridging and routing tables.

NCL commands beginning with “rget” are used to verify that the bridging
and routing tables represent the expected network topology. Rget
commands are based on SNMP; IP routing or IP host-only service must
be enabled to use them. The following are the Rget commands for each
bridging and routing service.

(For more information on Rget commands, refer to chapter 16 of the
Operator’s Reference.)

RGETB Use the Rgetb command to display the bridge forwarding and
filtering table for this node. Verify that the bridging service is learning
addresses. Verify proper configuration of source or destination address
filters.

RGETR Use the Rgetr command to display the IP routing table for
this node. Verify that entries exist for all IP subnetworks represented in
the network map. Check the next-hop entries to determine the route that
IP packets will take to each destination subnet. Verify the number of
hops to these subnets; a very large metric may indicate that the route is
invalid (type field I).

RGETIR Use the Rgetir command to display the IPX routing table for
this node. Verify that entries exist for all IPX networks represented in
the network map. Check the next-hop entries to determine the route IPX
packets will take to each destination network. Verify the number of hops
to these networks; a very large metric may indicate that the route is
invalid (type field I).

RGETIS Use the Rgetis command to display the IPX server table for
this node. Using your IPX network map, verify that the router has
learned about all IPX servers. Note that if IPX SAP filters are being used
in the network, your router may be restricted from learning about some
servers.

RGETXR Use the Rgetxr command to display the XNS routing table
for a this node. Verify that entries exist for all of the XNS networks
represented in your network map. Check the next-hop entries to
determine the route the XNS packets will take to each destination
network. Verify the number of hops to these networks; a very large
metric value may indicate that the route is invalid (type field I).

1-34

Installation

Verify router initialization and configurat ion.

RGETD Use the Rgetd command to display the DECnet router
configuration table. Use this table and the network map to determine
that all DECnet circuit groups are enabled and are currently active.

RGETDN Use the Rgetdn command to display the DECnet router
level 1 (intra-area) routing table for this node. Use this table and the
network map to verify that the router has learned about all routers and
end nodes in its area. Also, trace the paths to the destination nodes to
verify that the hop counts and path costs are as expected.

RGETDA Use the Rgetda command to display the DECnet router
level 2 (inter-area) routing table for this node. Use this table and the
network map to verify that the router has learned about a path to all
areas. Trace the paths to the level 2 router in the destination area to
verify that hop counts and path costs are as expected. Note that DECnet
routing services on HP routers are always level 1 and level 2 routing
services, but this may not be true for DECnet routing services from
other vendors.

RGETATR Use the Rgetatr command to display the AppleTalk routing
table. Verify that network range entries exist for all AppleTalk networks.
The network ranges should be consistent with those recorded on the
network map. Check the next-hop entries to determine the route that
AppleTalk packets will take to each destination network. Verify that the
number of hops to these subnets is what you expect. Check the status
field to verify that there are no entries that are marked suspect or bad.

1-35

Installation

Verify router initialization and configurat ion.

Test node accessibility.

Use NCL’s Ping command to test that specific IP routers or end nodes
can be reached. Ping can be used on a router with IP routing enabled to
test particular end nodes and routers that run IP. Use the specific IP
address of the target. To verify a newly installed router, perform the Ping
command on another router and use the IP address of the router being
verified as the destination.

To send an AppleTalk Echo Protocol (AEP) request message to a
specific AppleTalk node address, use NCL’s Atping command.

For more complete information on Ping, refer to page 3-18 in this
manual, and to chapter 16 of the Operator’s Reference.

Note If the steps in this verification section show that network links are not

operating as desired, re-examine the configuration performed in earlier
steps. Some links and services may need further customization beyond
your initial configuration; you may need to use the Configuration Editor
to change more parameters. (For information about using the Configura­tion Editor, refer to chapter 4 of the User’s Guide; for information about
the parameters and their defaults, refer to part I, “Dictionary of Configu­ration Parameters”, of the Operator’s Reference.) Return to the
configuration and booting steps earlier in this chapter, and then repeat
the verification steps.

Features

Features

The HP AdvanceStack Router 650 provides high-performance local/
remote bridging and multiprotocol routing for interconnecting LANs and
WANs. It supports the following routing services:

TCP/IP
Novell IPX
DECnet Phase IV
AppleTalk Phase 2
Xerox XNS
Transparent Bridging with Spanning Tree
Translational Bridging
Source Route Bridging
Synchronous Pass-Through

If a packet arrives with an unsupported protocol, the router uses its
bridging capability to send the packet toward its destination. This allows
full support for environments where non-routable, uncommon, or
unsupported protocols may exist.

The router can accomodate up to four interface cards, such as the HP
J2434A 4-Port WAN Interface. This interface card includes four WAN
ports supporting RS-232/V.24/V.28, RS-422/RS-449/V.36, V.35, or X.21
interfaces. These provide direct point-to-point, PPP, and ISDN connec­tions to other routers. WAN support includes private, public, or hybrid
networks using X.25, Frame Relay, SMDS, and ISDN, over point-to-point
and/or switched circuits, with support for dial connections.

For a list of all interface cards that can be installed in the router, refer to
the HP Network Connectivity Product Catalog.

A console port allows access to the router by a terminal, or by a terminal
emulator on a personal computer. Through this interface, you can
configure, monitor, and troubleshoot the routers. This RS-232 console
interface can be accessed either locally, or remotely through a modem.
The baud rate is automatically detected. Also, enhancements to the
router’s operating system can be downloaded to the router through this
port.

2-2

Description and Operation

Additional Features:

Optional redundant power supply (HP J2446A) ensures maximum

uptime. Front-panel indicator light signals power supply failure.

Optional 8-Mbyte memory upgrade (HP J2443A) increases memory

on the routing engine to 16 Mbytes.

Interface cards, power supplies, and cooling module can be hot

swapped.

“Quick Remote” automatically satisfies Bootp requests from other

HP routers, which eliminates the need for technical expertise at

remote sites.

Detachable brackets for mounting in a 19-inch rack or cabinet.

Automatic sensing of the power voltage range with no switches

needed.

Redundant variable-speed fans ensure maximum uptime. Front-

panel indicator lights signal temperature or cooling-module failure.

Features

The option to automatically recover from power failure while

maintaining the current configuration.

Front-panel LEDs that are clearly visible at a glance. These LEDs

include a global status LED to indicate overall health or failure at a

glance. More detailed is provided by LEDs for port traffic, net failure,

processing utilization, and diagnosis of particular modules and

options.

Also, you can remotely manage an HP router through a workstation
running HP OpenView Interconnect Manager in HP-UX, or through any
other standard SNMP network management system.

After using the console interface with Quick Configuration to configure
IP routing, you can use such applications on network servers to do all
other router configuration remotely.

The Status LED is a quick indicator of the overall state of the router.
When it is lit green, the router is operating normally; when it is lit
orange, some failure has occurred, and you should check for other
orange LEDs to determine the cause of the failure.

Status appears:

Green when the router is operating normally and when the self-test

is complete with no errors. (The Status LED remains green when a

network is down or when an interface slot is empty; these conditions

allow the remaining interface cards to operate normally.)

Orange when the self-test is running. (A full self-test occurs when

the power is switched on; it lasts 15–35 seconds, depending on how

many interface cards are installed. A minimal self-test occurs when

the Reset or Diag button is pressed; it lasts about 7 seconds.) If an

error is found during the self-test, the Status LED remains orange

and one or more of the other router status or module status LEDs

will also be lit orange. It also remains lit during the configuration

clearing procedure (page 2-12).
The Status LED also appears orange when there is a failure of the fan

or of one of two installed power supplies, or when there is a tempera­ture warning.

the power switch is not lit.

Fan appears orange when there is a failure in the cooling module. If the
Fan LED is lit during router operation, replace the cooling module.

Temp appears orange when the temperature exceeds specifications. If,
during operation of a router mounted in a cabinet, the Temp LED is lit
and the Fan LED is not lit, verify that the airflow around the router is not
restricted. The temperature where the router is installed should be
within the range specified in appendix C.

The Pwr, Fan, and Temp LEDs also appear orange momentarily at the
beginning of the self-test.

Figure 2-6. Location of Reset, Clear, and Diag But tons

The Reset, Clear, and Diag buttons on the routing engine let you perform
the following tasks:

Resetting the router runs a minimal self-test and initializes (boots)

the router, regardless of the current operating mode.

Clearing the password(s) removes the current password(s), if any,

without interrupting the current state of the router. This protects you

from being denied console, Telnet, TFTP, or HP Openview Intercon-

nect Manager access if you have forgotten the password(s).

Clearing the router removes the current password(s), erases all

configuration changes to the default (factory) configuration, and

boots the router. Use this feature only if you are prepared to lose the

router’s current configuration. You must use this procedure if the

configuration is so corrupted that the console becomes inaccessible.

Factory

Test

Obtaining diagnostic information by pressing the Diag button

resets the router and generates diagnostic messages that appear on

the console, in the event log (which can be displayed from the Main

menu), and in the crash history (which can be displayed using NCL’s

Crash command).

Description and Operation

LEDs and Buttons

Resetting the Router: The Reset Button

Using a non-conducting, pointed implement such as a wooden pencil or
a toothpick, press and release the recessed Reset button on the routing
engine. (See figure 2-6 on page 2-9.) Resetting does the following:

Lights all router , module, and port status LEDs while the Reset

button is pressed.

Runs a minimal self-test of the routing engine. During the test, the

Status LED for the router is orange, the Card LED for the routing

engine is orange, and the Self-test LED for the routing engine is

green.

Initializes (boots) the router, using the most recently saved

configuration.

Displays “Waiting for speed sense” on the console so you

can start a console session if needed. (Refer to “Plug in and verify

router hardware” on page 1-18.)

Switching the power off and then on resets the router as described
above, plus it performs a more extensive self-test. However, while
pressing the Reset button preserves the event log (which can be
displayed from the Main menu) and the crash history (which can be
displayed using NCL’s Crash command), this information is lost when
you switch the power off and on.

For more information about resetting, see “Initialization Sequence” on
page 2-15.

Notes Resetting does not affect any current password(s).

Any configuration changes you have not yet saved (in either Quick
Configuration or the Configuration Editor) are discarded. That is, the
router initializes with whatever configuration was last saved.

If the Status LED does not turn green within a couple of minutes after
pressing and releasing the Reset button, the self-test has failed. In this
case, check the Pwr, Fan, Temp, and Card LEDs for the error and refer
to chapter 3, “Troubleshooting.”

Clearing the Passwords: The Clear Button

Using a non-conducting, pointed implement such as a wooden pencil or
a toothpick, press and release the recessed Clear button on the routing
engine. (See figure 2-6 on page 2-9.)

Note

Access to the router will no longer be limited by either a manager or
user password. Using the Clear button removes all constraints on access
by anyone using the console, Telnet, TFTP, or network management.

To set new passwords, use the Network Control Language (NCL)
Password command on the console. For more information, refer to
chapter 16 of the Operator’s Reference or to “Set manager and user
passwords" in this manual, page 1-28).

Description and Operation

LEDs and Buttons

Clearing the Router: The Reset and Clear Buttons in Combination

The combination of the Reset and Clear buttons restores all factory
defaults, including configuration defaults. It also removes the manager
and user passwords. You might want to use this procedure (as described
below), for example, in situations such as the following:

So many settings in the configuration need to be changed that it

would be easier to start over with the factory defaults.

You want to redeploy the router somewhere else using a different

configuration.

The configuration has become so corrupted that you cannot access

the router from the console.

Caution The Reset-Clear combination erases the changes made to the router

configuration and restores the default (factory) configuration values.
This means that bridging (without spanning tree), but not routing, is
then enabled on all ports.

Note The Reset and Clear buttons are recessed. To press each button, use a

non-conducting pointed implement like a wooden pencil or a toothpick.
(See figure 2-6 on page 2-9.)

2-12

Description and Operation

LEDs and Buttons

Note Do not wait more than 5 seconds after step 2 below. Holding the Clear

button too long prevents this procedure from working.

1. Press the Reset button, and while holding it down, immediately press
and hold the Clear button.

All LEDs are lit while Reset is pressed. (All Card LEDs are orange,
and all Self-test LEDs are green.)

2. Release the Reset button, but continue to hold the Clear button.
The Card LEDs turn orange, and the Self-test LED for the routing

engine begins flashing.

3. Release the Clear button within five seconds.

Note If the Self-test LED has stopped flashing (and the Status LED has turned

orange), you waited too long—prevents this procedure from working. If
this happens, recover by restarting the procedure. (If a console is
connected, the interface for RMON will appear; you can ignore it and
restart the procedure.)

The Self-test LED stops flashing and remains lit during the self-test
portion of the initialization sequence. (For more information about

LEDs and Buttons

Obtaining Diagnostic Information: The Diag Button

Using a non-conducting, pointed implement such as a wooden pencil or
a toothpick, press and release the recessed Diag button on the routing
engine. (See figure 2-6 on page 2-9.)

Pressing the Diag button resets the router just as does pressing the
Reset button, plus it also generates diagnostic messages that appear on
the console, in the event log (which can be displayed from the Main
menu), and in the crash history (which can be displayed using NCL’s
Crash command; for details, refer to chapter 16 of the Operator’s
Reference). When the router appears to “hang,” use the Diag button
rather than the Reset button. If this does not reset the router, then try
pressing the Reset button.

Some of the diagnostic tips in tables 3-1 and 3-2 refer you to entries in
the event log (which can be displayed from the Main menu) and the
crash history (which can be displayed using NCL’s Crash command). To
display either the event log or the crash history, you must have a console
connected to the router before you switch the router on, with the PC or
terminal set to 9600 baud.

2-14

Description and Operation

Initialization Sequence

Initialization Sequence

Whenever the router is powered on, or when its Reset or Diag button is
pressed:

1. The router automatically goes through a self-test. (A full self-test
occurs when the power is switched on; it lasts 15–35 seconds,
depending on how many interface cards are installed. A minimal
self-test occurs when the Reset or Diag button is pressed; it lasts
about 7 seconds.) During the self-test, the Status LED for the router
is orange, the Card LED for the routing engine is orange, and the
Self-test LED for the routing engine is green.

Note If you boot the router using NCL’s Boot command or the booting option

in Quick Configuration on the console, the initialization sequence begins
at step 2.

2. The router’s clock is reset to the time the router was last running. Or,
if the Time Protocol is configured to run on this router, the time is set
to the time found on a time server.

3. The router operating code (software) is automatically executed.

4. Dynamic variables (such as the counters and events) are reset.

5. The configuration is read from the PCMCIA flash card into active
circuitry. This implements any configuration changes saved since the
router was last reset.

6. Communication is automatically started with the devices that are
connected to the router and with the routing applications that are
configured. Bridging and routing tables are reset.

(Procedures for connecting devices are in chapter 1, “Installation.”
Procedures for configuring routing applications are in the User’s
Guide.)

2-15

Description and Operation

Initialization Sequence

7. If a console is connected to the router, the session is restarted. The
message “Waiting for speed sense” appears on the console.
Since the correct speed for your terminal has not been sensed yet,
that 9600-baud message may appear garbled. When you see the new
text on your console (or simply a few seconds after the Self-test LED
turns off), press [Return] and pause. Repeat if necessary until the router
senses and matches your baud rate. Your console session then begins.

(The detailed procedure for connecting a console is in chapter 1,
“Installation.”)

Basic Troubleshooting Tips

Note Some of the router’s console commands are used for the troubleshooting

instructions in this chapter. Refer to “Connect a console” (page 1-14) for
details on connecting to the console port. For details on the Configura­tion Editor, refer to chapter 4 of the User’s Guide. For details on NCL
(Network Command Language Interpreter) commands, refer to chapter
16 of the Operator’s Reference.

Make sure that you have a valid network topology. If you have
trouble after a recent change to the network, switch back to the
previous topology. If you no longer have trouble, the new topology is
probably at fault.

Make sure that the router is plugged in and that cable connections
are secure.

If the console port does not work, refer to “Connect a console” (page
1-14), and then check “Troubleshooting a Terminal or Modem
Connection” (page 3-14.)

Check the router status, module status, and port status LEDs. For
information about using patterns of these LEDs to diagnose failures,
refer to tables 3-1 and 3-2 (pages 3-3 through 3-8). For more details
regarding these LEDs, refer to “LEDs and Buttons” in chapter 2
(page 2-4).

If none of the troubleshooting procedures in this chapter solves the
problem, press the Diag button on the routing engine. If the problem
persists, call for service from your HP dealer or service provider.

Interpreting LED Error Patterns

If a failure occurs when power to the router is cycled (switched off and
on), refer to table 3-1 below for information about using LED patterns to
diagnose the failure. If a failure occurs during router operation, refer to
table 3-2 (page 3-6).

Notes In tables 3-1 and 3-2, a black box indicates an orange LED, a gray box

indicates a green LED, and an empty box indicates an unlit LED.

Some of the diagnostic tips in tables 3-1 and 3-2 refer you to entries in
the event log (which can be displayed from the Main menu) and the
crash history (which can be displayed using NCL’s Crash command). To
display either the event log or the crash history, you must have a console
connected to the router before you switch the router on, with the PC or
terminal set to 9600 baud.

If an LED error pattern according to table 3-1 or 3-2 seems to indicate a
failure but the router nevertheless appears to be operating correctly,
refer to “Verifying LED Operation,” page 3-9.

For most interface cards, the 3rd, 7th, 11th, and 15th LEDs are used to
indicate the Port Number, and the 6th, 10th, 14th, and 18th LEDs are
used to indicate Net Fail—as shown in this table. If a particular interface
card uses these LEDs differently, its documentation describes that use.

If you suspect a non-operating LED—for example, if the LEDs indicate a
failure as shown in table 3-1 or table 3-2, or they have some anomalous
pattern (for example, off or red); but the router nevertheless appears to
be operating correctly—you can verify the LEDs by resetting the router
using the following procedure.

Caution Resetting the router causes bridging and routing tables to be reset. For

other effects, see “Initialization Sequence” on page 2-15.

Press and hold the Reset button, and verify that while you are holding it,
all of the router status, module status, and port status LEDs are lit. Also,
for each interface card, verify that the Swap LED is lit and that the
colors of the port status LEDs match those shown in table 3-3
(page 3-10).

If any of the router status, module status, and port status LEDs is not lit,
or if any LED that table 3-3 indicates should be orange appears green or
red instead, the router must be replaced.

If a Swap LED is not lit, you can use the card, but it should not be hot
swapped: if you need to replace the card, you should use the procedure
“Replacing the Routing Engine or an Interface Card (System Offline)”
(page 3-27) rather than the procedure “Replacing an Interface Card

“Connect a console” (page 1-14), then try the “Reset speed sensing,”
Adjust baud rate," and “Reset the terminal” procedures (pages 3-14
through 3-15) in sequence.

If none of those procedures result in proper console access:

1. Check the LEDs (refer to “Interpreting LED Error Patterns,” page

Ping

Ping is a network-layer test that sends an Internet Control Message
Protocol (ICMP) echo request message to another node that has an IP
address and is able to respond to an ICMP echo request message. The
router must have IP routing configured in order to use this test.

1. From the Main menu, select the Network Control Language
Interpreter (NCL). The NCL prompt then appears at the bottom of
the screen. (See figure 3-1 on page 3-16.)

At the NCL prompt, enter one of the following sequences:

ping x.x.x.x [Return]
ping x.x.x.x count [Return]
ping x.x.x.x count wait [Return]

where:

x.x.x.x is the target node’s IP address in dotted decimal
notation.

count (optional) is the number of times to repeat the echo
request packet. If an integer is not included, the packet is sent
once.

wait (optional) is how many seconds to wait for a response. If
a second integer is not included, the response must be received in
five seconds to be successful.

2. You will see a message, indicating either that the target node is
alive—meaning that communications are passing successfully from
the router to the remote node on a specific link—or that the remote
node did not respond. If you cannot reach any remote node, the
problem must be isolated to the router, the links used in the test, or
all of the remote nodes.

where:

x is the target node’s network number.
y is the node identifier.
wait (optional) is how many seconds to wait for a response. If

a second integer is not included, the response must be received in
five seconds to be successful.

2. You will see a message, indicating either that the target node is
alive—meaning that communications are passing successfully from
the router to the remote node on a specific link—or that the remote

Telnet

Telnet is an upper-layer service that allows you to interact with a remote
node’s console interface, by establishing a virtual terminal connection.
This section describes the Telnet console connection from an HP router
that has IP routing and a Telnet session configured to a router or end
node that has Telnet service and is suspected of not routing successfully.

4. From the Main menu, select the Network Control Language Inter­preter (NCL). The NCL prompt then appears at the bottom of the
screen. (See figure 3-1 on page 3-16.)

5. At the NCL prompt, enter the Telnet command:

telnet x.x.x.x [Return]

where:

x.x.x.x is the IP address of the remote node
in dotted decimal notation.

6. Once the connection is established, Telnet passes your keystrokes to
the remote system.

If the remote system is another HP router:

a. You will see the system name of the remote node as the NCL

prompt at the bottom of your display. Check the event log and
routing tables of the remote node as you do for your own router.
Use the Exit command to leave NCL and return to the remote
node’s Main menu:

exit [Return]

b. To disconnect the Telnet session, use the Logout option from the

remote node’s Main menu, and when you are prompted with:

Do you want to disconnect? [Y/N:]

press [Y] for “yes”. The remote node is disconnected, the Telnet
session ends, and your local node’s system name appears as the
prompt on your display.

If the remote system is not another HP router, then type the
appropriate commands to interact with that system and to
disconnect Telnet.

7. Use the Exit command to exit from NCL and return to the Main
menu:

Replacing a Module

Replacing a Module

You can replace any interface card or the cooling module without taking
the system offline (that is, without switching the router off and taking all
networks down). If you have installed a second power supply, you can
also replace either power supply without taking the system offline.
(Replacing a module without taking the system offline is often called
“hot swapping.”)

To replace the routing engine or the PCMCIA flash card, or to replace
the power supply if a second power supply has not been installed, you
must take the system offline; refer to “Replacing a Module (System
Offline),” page 3-27.

Replacing an Interface Card (System Online)

Notes If you are replacing an interface card with a different type of interface

card (for example, if you are replacing an Ethernet/802.3 card with a
token ring card), or if you are installing a card in a slot that formerly was

Replacing the Routing Engine or an Interface
Card (System Offline)

Notes The router’s configuration information is stored in the PCMCIA flash

card mounted on the routing engine. If you need to replace the routing
engine because of some problem other than one in the flash card and
you don’t want to re-enter the configuration information, refer to
“Replacing the PCMCIA Flash Card,” page 3-31.

If you are replacing an interface card with a different type of interface
card (for example, if you are replacing an Ethernet/802.3 card with a
token ring card), or if you are installing a card in a slot that formerly was
empty, you must specify in the configuration the new card for that slot
after the card has been installed. (Refer to “Configure and boot the
router,” page 1-21.)

The following installation procedure is applicable to the routing engine
and to any of the interface cards. For installation procedures specific to
a particular interface card, refer to the documentation provided with it.

1. Disconnect all cables from the module, and save them for reconnec­tion after the new module is installed.

Replacing the PCMCIA Flash Card

A new PCMCIA flash card is not available from HP separately from the
routing engine. If the flash card needs to be replaced, you must replace
the routing engine; the replacement routing engine comes with a new
flash card preinstalled on it.

The configuration is stored in the flash card. If you need to replace the
routing engine because of some problem other than one in the flash card
and you don’t want to re-enter the configuration, you can use the follow­ing procedure to install your current flash card in place of the new one
provided with the new routing engine.

Note Instead of using the procedure below, you can transfer the configuration

from your current flash card to the new flash card using NCL
commands. First, copy the configuration from your current flash card to
another router or to a PC console. (To ensure accurate transfer of the
configuration, it’s best to do this after making a change to the configura­tion and before a router failure occurs.) Next, install the new routing
engine; finally, copy the configuration from the other router or the PC
console to the new flash card on the new routing engine.

For information about copying a configuration to another router over a
network, refer to “Using TFTP to Transfer Operating Code, Configura­tion, and NCL Display” in the User’s Guide. For information about
copying a configuration to a PC console, refer to “Using PC Modem
Access to Transfer Configuration and NCL Display” in the User’s Guide.

1. Remove the routing engine using steps 1–7 of the procedure
described under “Replacing the Routing Engine or an Interface Card
(System Offline)” (pages 3 -27 through 3-29), and place it on a flat
surface.

2. Connect a grounding wrist strap to your wrist and to the tray of the
routing engine.

Replacing the Power Supply

If a second power supply has been installed, you can replace either of
the two power supplies without taking the system offline (that is, you
can “hot swap” one of two installed power supplies).

Caution Be careful not to open the router door more than 90°. Opening the door

further could damage it.

Note If a second power supply has been installed and one of them has been

found to be faulty (that is, the Pwr LED is lit), the faulty power supply is
the one for which the switch LED is not lit.

1. Disconnect the power cord from the faulty power supply, and save it
for reconnection after the new module is installed.

2. Open the front door of the router by pulling its lock—the round post
at the upper right—to the right.

Figure 3-14. Opening Router Door

3. Using a Torx T-10 screwdriver, remove the screw(s) from the top cor­ner(s) of the power supply. (See figure 3-15.) A power supply in­stalled in the left compartment has screws in both corners; a power
supply installed in the right compartment has a screw only in the up­per-left corner.

Note In the next step, be sure that the cooling module is perfectly vertical and

is perfectly parallel to the router. If the module is tilted, you might not be
able to insert it further into the module housing.

6. Holding the door open at 90°, place the new cooling module at the
front of its housing, then carefully push it back into the housing until
the mounting ears for the screws are about 1 inch from the holes in
the router chassis. You may need to wiggle the cooling module
and/or adjust its position so that it slides in properly.

‡

If this cable is used, the DTR signal must be on (high) in your terminal emulation program or in your terminal, and
the parameters “Enable DTR on Initialization” and “Ignore DCD” must be left at their default settings (refer to
“Configuration of Console Signals” on page A-3).

A-2

Cables and Adapters

Configuration of Console Signals

You can specify in the configuration how the router handles the DTR
(Data Terminal Ready) and DCD (Data Carrier Detect) signals. (DCD is
sometimes referred to simply as CD, Carrier Detect.)

DTR

The parameter “Enable DTR on Initialization” in the User Session menu
of the configuration controls whether the console port always maintains
DTR on (high). Use the default setting of “Yes” if the console port is
directly connected to a PC or terminal.

If the console port is connected to a modem and you experience modem­related problems—for example, if the modem answers prematurely or
attempts to dial the phone—change this setting to “No.”

DCD

The parameter “Ignore DCD” on the User Session menu of the configura­tion controls whether the console port ignores DCD. When DCD is not
provided to the console port—for example, if you are using the supplied
console cable to directly connect to a PC or terminal— this parameter
should be left at the default setting of “Yes.”

(When the router is configured to ignore DCD, the transition to a
connected state is determined by the state of the DSR signal. When DSR
transitions to ON, the router attempts to speed sense; when DSR
transitions to OFF, the router terminates the session.)

Change this setting to “No” if the console port is connected to a cable or
device that maintains DCD on (high).
