Installation

Phase 2: Prepare the Network

1. Create or update the network plan. Include power sources,

computers, data links, hubs, repeaters, bridges, other routers, and

cabling (including types and lengths). Verify the design limits for the

cable lengths and the number of repeaters and nodes in your

network.

2. Create or update the network map. This map provides a diagram of

how the network topology now looks or will look as the router

hardware is installed. Generally, this diagram includes:

• The physical location of each network device and end node

• The connections between each device and end node

• The network-layer addresses for identifying network and links

For each LAN link, include the following on the map:

• LAN type (Ethernet/802.3, Token Ring/802.5, or FDDI)

• LAN speed (4, 10, 16, or 100 Mbit/s)

• Physical medium (cable type)

1-4

For each WA N link, include the following on the map:

• WAN link type (circuit type) and WAN link sp eed

• Interface type (X.21, V.35, etc.)

• HDLC address (DCE/DTE) for HP Point- to-Point links

• X.121 address and connection ID (for X.25 links)

• Quality of service (LLC1, LLC2, X.25)

• Other pertinent data, such as:

– ISDN, switched 56, or other dial type numbers – Frame relay DLCI encoding type and length, and management

type (ANSI Annex D, Annex D switch, LMI, or LMI switch)

– SMDS individual address

If you use multiple protocols (routing or bridging services) in your

network, you may want to make a separate map for each protocol.

3. If the router will be configured from another router using Quick

Remote or from a Bootp server, ensure that the Quick Remote or

Bootp operation has been enabled on the remote devices. (For more

on remote configuration using Quick Remote or Bootp, refer to the

User’s Guide shipped with your router.)

Installation

Phase 2: Prepare the Network

4. Before you apply power to the router, connect all LAN and WAN

links to the router. Verify the LAN cabling and that the WAN link

terminating equipment is operational. Your WAN link service

provider can verify that the WAN link is operating correctly.

Note

Configuring from Quick Remote or a Bootp s erver requires that the supporting WAN and/or LAN links be connected before the router boots from the factory default.

5. Use a console as described in this chapter to verify and configure the

router. The console must be an ANSI or VT100 terminal or a PC

running an ANSI or VT100 terminal emulator. You also need either a

cable or a modem and a modem cable for connecting the console.

(Refer to appendixes A and B.)

Console Note Connecting a console to the router’s console port is optional if the router

will be configured and administered from a remote site. That is, if the router will be automatically configured using Quick Remote or a Bootp server, then a remote operator can verify and administer the router over the network.

Phase 3: Prepare the Router Hardware

B. Connect a Console (Optional)

When Is a Console Necessary?

Connecting a console is necessary if your managem e nt of the router requires direct access through the console port by either a local operator or by a remote operator using a modem. Direct access through the console port is optional if the router is to be configured from a remote site using Smartboot (Quick Remote or a Bootp server) and if the router is to be managed from a remote site using Telnet.

To install a console:

1. Do one of the following:

• Connect the serial port of an ANSI or VT100 terminal (or a PC emulating one of these) to the console port using an RS-232 cable.

• Connect a full-duplex, asynchronous (character-mode) modem to the console port using an RS-232 cable. 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 according to the modem instructions.

Note For recommended console and modem cables, and cable pin-outs, refer

to appendix A, ‘‘Cables and Connectors’’. For supported modems and their configuration requirements, refer to appendix B, ‘‘Modem Configuration’’.

2. Switch on the terminal’s power (or switch on the PC’s power and start the terminal emulation program). Configure for the following:

• ANSI or VT100

• 1 stop bit

• 8 bits/character

• Xon/Xoff handshaking

• No parity

• Baud rate of 57600, 38400, 19200, 9600, 4800, 2400, 1200, or 300

• Screen size of 24 lines

Installation

Phase 3: Prepare the Router Hardware

Connecting an FDDI Ring to the FDDI Interface

FDDI connections on HP routers use a dual-port FDDI interface with optional node bypassing. Node bypassing is achieved by using an optical bypass switch, also known as an “FDDI dual-switch module”. (For part number, refer to the release notes you received with your router or most recent software upgrade.) Using a bypass switch to connect your FDDI ports to an FDDI network prevents the FDDI network ring from ‘‘wrap-

in cases when your router is connected as a dual-attach station

ping’’ (DAS) and powers down. FDDI operation requires HP router software version 5.76 or later.

This subsection describes basic connections between the router and the FDDI ring. For more information on cable conf igurations connecting the HP Router BR to dual-attach and single-attach stations (DAS and SAS), refer to appendix D, “FDDI Cable Attachment Configurations”.

For an illustration of ‘‘wrapping’’, refer to ‘‘FDDI Port (Router BR Only)’’ on page 2-11.

To determine the current version of software in your router, use the Stamp command in the Network Control Language Interpreter (NCL). For more on NCL commands, refer to the user’s guide you received with your router.

Installation

Phase 3: Prepare the Router Hardware

1. Disconnect the router from any directly connected FDDI ring.

2. Connect the bypass switch to the FDDI ring by plugging the MIC A

and MIC B connectors from the FDDI ring into the corresponding ‘‘A’’ and ‘‘B’’ ports in the bypass switch. (For details on connecting to the FDDI ring, refer to the instructions for your bypass switch.)

3. Ensure that the bypass cables are keyed properly to allow only the

connection of the ‘‘A’’ cable to the router’s ‘‘MIC A’’ port and the ‘‘B’’ cable to the router’s ‘‘MIC B’’ po rt. (Refer to the instructions for your bypass switch.)

4. Connect the bypass cables to the FDDI ports as shown above.

5. Insert the DIN connector on the bypass unit into the Optical Bypass

jack on the HP Router BR.

Note The router will not detect the presence of a new connection to the FDDI

ring until you reboot the router (which is covered later in this chapter).

1. Attach the male end of the cable to the router’s WAN port.

Hand-tighten the screws attached to the cable connector.

2. Attach the other end of the cable to the WAN link terminating

equipment.

Note If any port has no network attached, the port’s Net Fail LED goes on

after the router starts.

Phase 3: Prepare the Router Hardware

D. Plug In and Verify the Router Hardware

When you power up a router that is in the factory default state1 (or if you clear it by using the Clear/Reset button combination--page 2-17), the router sends Bootp requests over all active ports for one minute. Depending on the response from the network, th e rout er then does one of the following:

If the router does not receive a response from either a Quick Remote or Bootp source within approximately one minute of receiving power or being cleared, it configures itself as a bridge and begins bridging operations.

If the router receives a minimal configuration over a WAN link from a Quick Remote source, it boots itself with this configuration and begins routing and bridging operation accordingly. (For information on Quick Remote set-up and operation, refer to the User’s Guide shipped with your router.)

If the router receives a reply from a Bootp server, it configures itself with the intermediate configuration contained in the reply. The router then attempts to download a full configuration from the TFTP server indicated in the Bootp reply message. Following download of the full configuration, the router then reboots itself and begins routing and bridging in accord with the full configuration. (For information on set-up and operation with a Bootp server, refer to the User’s Guide shipped with your router.)

Note When powered up in the factory default, the router, by default, begins

bridging on all ports if Smartboot does not elicit a configuration from a remote source (described above). Thus, if the router is expected to use Smartboot for configuration, but instead begins operating in the default bridging mode due to some unforseen problem, there may be unexpected effects on the adjacent networks. For this reason, it is recommended that you attempt to identify potential network responses to (unexpected) default bridging before powering up the router for the first time (or clearing the router to the factory default).

The router is shipped from Hewlett-Packard in the ‘‘factory default’’ configuration. Changing the configuration in any way and then rebooting the router replaces the factory default with the new configuration. To return the router to its factory default, clear it by using the Clear/Reset button combination described on page 2-17.
