QUICK INSTALLATION

This section takes you through a step-by-step minimum installation and setup procedure for the internet/print server. Please refer to the main text of this manual for detailed information about the setup and operation of this device.

Getting Started

Step 1: Unpack the device. Make certain no components have

been lost or damaged. A packing list is provided on page 11.

Step 2: Choose an installation site on a flat, level surface or wall

near the modem or ISDN/TA you plan to use for internet connections or near the network line you plan to use for a LAN connection, and near the printer you would like to share through the server. Note that the internet/print server can be hung on a wall using the wall mounting equipment included with the product.

Making Connections

Step 3: Connect the internet/print server to your LAN using a

Category 3, 4 or 5, twisted-pair cable and the device’s single RJ-45 LAN port. This connection should be made to an Ethernet or Fast Ethernet switch or hub. (The RJ-45 port looks like a phone jack.)

Quick Installation 1

Internet/Print Server User’s Guide

Step 4: Connect the internet/print server to the printer using the

LPT port and a parallel cable. See Chapter “Print Server Setup” for information on how to setup the print server settings and see the IS Admin User’s Guide for information on shared print services.

Step 5: Connect the internet/print server to a modem or ISDN/TA

using the device’s serial port (COM). (Note that your modem or ISDN/TA should already be connected and setup according to the instructions included with it.)

Step 6: Plug the power adapter into the device and into an outlet.

Quick Installation2

Configuration

Step 7: Before you can use your internet/print server, IP addresses

on your LAN’s PCs must be set so that they are compatible with the internet/print server’s settings. The internet/print server comes with the default local IP address: 192.168.100.1 and the default subnet mask setting: 255.255.255.0. Assum- ing that you leave these settings unchanged and assign fixed IP addresses to machines on your LAN that will access the Internet through the internet/print server, you must give those machines IP addresses in the range of 192.168.100.xxx, where xxx is a number from 2 to 255. (If you want to use a different IP address range, see “Setting IP Addresses” on page 21.) You can, alternatively, set the machines on your LAN to obtain their IP addresses automatically using DHCP to get IP addresses from the internet/print server. Whether the machines use fixed IP addresses or DHCP, they must all use the same subnet mask setting as the internet/print server, and the internet/print server’s local (LAN) IP address must be set as each machine’s default gateway.

Step 8: The internet/print server can be configured and operated

via Telnet or a web browser once PC IP addresses have been properly set. (Note that some device settings can be manipulated using the IS Admin program included with the device.) Start your Telnet or browser software and enter the IP address of the internet/print server (either the default IP listed above or the new address you assigned using IS Admin). This should bring up the internet/print server start menu. See the next series of steps for information about settings that must be set for the device to work properly.

Quick Installation 3

Internet/Print Server User’s Guide

Mandatory Settings for Internet Access

Step 9: ISP Account -> Phone Number, when you signed-up for

an account with your ISP (internet service provider), you should have been given an access phone number that your modem will dial. Look under the “WAN Port Settings” menu for this setting and enter the phone number provider by your ISP.

Step 10: ISP Account -> User ID, your ISP should also have

assigned a User ID (aka, a username) that you will use for logging-in. Also under “WAN Port Settings,” enter this user ID exactly as it was provided to you.

Step 11: ISP Account -> Password, finally, to complete the ISP

login process, the internet/print server must provide the password associated with the user ID assigned by your ISP. Enter it.

You have now completed the basic steps necessary to install, configure, and begin using the internet/print server. Note that, with respect to steps 9–11, it may be necessary for you to use a “Login Script” instead. If you enter the information required in those three settings correctly and still have trouble logging-in, see the “Login Script” section on page 30 to create a login script.

Internet Server Technology

The concept behind internet servers is to provide internet access for multiple users through a single internet account. Without an internet server, each end node (i.e., PC or workstation) on a LAN must have it’s own public domain (global) IP address.

Single Global

(single

end user)

IP Address

176.220.22.1

Using an internet server allows a single global IP address to be shared by multiple end nodes simultaneously.

Introduction8

In this implementation, it is only necessary to pay for a single internet account even though many people will be able to use it.

Non-Internet Implementations

An internet server can also be used to expand a LAN by creating a localized IP “sub-group”. In this LAN-to-LAN configuration, the internet server links the two IP subgroups (as shown below). This implementation is useful when the LAN has run out of IP addresses. The internet server uses a single IP address from the first (global) LAN to establish a second (local) LAN, in much the same way it allows many users to connect to the internet through a single IP address. PC’s on the second LAN (called a local LAN since the IP addresses of computers on this LAN are managed by the internet server) can still access the internet by setting their Gateway address to the IP address of the local LAN port of the Internet server. Please

Installation 13

Internet/Print Server User’s Guide

Serial – WAN

The serial port is used for a WAN connection either to a modem or an ISDN terminal adapter. The serial port is a standard male 9-pin RS-232 connector.

Parallel – Printer

The parallel port is used for connecting to a printer for sharing to the LAN. This port is a standard female 25-pin parallel connector.

RJ-45 – LAN

The internet/print server has a single, NWay RJ-45 LAN port. This port is 10Mbps and 100Mbps capable (auto-detect, auto-configure) and designed for use in an Ethernet or Fast Ethernet LAN via a network hub. The port has standard RJ-45 pinouts.

LED Description

The internet/print server has a small LED array for indicating current port and transmission status. The power/transmit (Pw/Tx) and connect/receive (Link/Rx) LEDs only relate to activity on the LAN port. All other LED indicators display information about their related ports as labeled.

Installation14

DP-802 Front Panel / LEDs

Pw/Tx

The Pw/Tx (power/transmit) LED lights when power is supplied to the device and flashes when the LAN port transmits data.

Link/Rx

The Link/Rx (link/receive) indicator will light up when a good connection is made at the LAN port with an operating and compatible Ethernet or Fast Ethernet device. This indicator flashes when the LAN port receives data from the network.

COM

The COM port LED provides an indication of the operating status of the WAN port. When the WAN port is transmitting data, the COM port will light. If no data is being transmitted, the COM LED will be off.

Installation 15

Internet/Print Server User’s Guide

LPT

The LPT port LED lights to indicate when data is being sent to the network printer it is connected to. If no data is being transmitted, the LPT LED will be off.

Normal LED Flash Pattern

Immediately after power-up, all four of the LEDs should display steady green for several seconds. Then the COM LED and LPT LED should flash simultaneously three times. This sequence of flashes should be followed by first the COM LED flashing once and then LPT LED flashing once, repeated three times in succession. If as problem with the device is detected during this time, the LED flashes will display an error pattern (see Appendix A: Troubleshooting for more information on POST error indications). If no errors are detected, the internet server will begin operating normally.

Connecting to the Local Network

The internet/print server includes one RJ-45 NWay LAN port. To connect the device to your LAN, use a standard Category 3, 4, 5 UTP, or STP twisted-pair cable to link the device to an Ethernet or Fast Ethernet hub or switch.

Cable length limits must conform to Ethernet and Fast Ethernet wiring rules. Ethernet cable segments can be a maximum of 100 meters. Fast Ethernet wiring rules also limit the maximum length of cabling segments to 100 meters.

Once the internet/print server is physically connected to a local network and you have used the IS Admin software included to assign an IP address to the device (or simply reconfigured your

Installation16

PC’s IP address, subnet mask and gateway to match the default settings of the internet/print server), you may configure other parameters from your network station using Telnet or a web browser.

LAN Connection

Installation 17

Internet/Print Server User’s Guide

Connecting to the Internet

The internet/print server must be connected to the internet (this is also known as a “Wide Area Network or ‘WAN’” connection) using the COM serial port. The COM port can either be connected to the serial port of a modem (or fax/modem), or to an ISDN terminal adapter. The faster the WAN connection is, the faster access will be and the more users will be able to get on the internet simultaneously.

Connect the COM port of the internet/print server to a modem or ISDN terminal adapter using a standard serial cable.

Modem Connection

Installation18

Connecting Power

Power is supplied to the internet/print server through an AC power adapter.

Connecting Power

Since the internet/print server does not include a power switch, plugging its power adapter into a power outlet will immediately power it on.

Installation 19

Internet/Print Server User’s Guide

INTERNET SERVER

SETUP

Before it can be used, the internet/print server has some settings that need to be properly set. This chapter describes how to change default IP settings and then how to use Telnet or a web browser to manipulate the internet/print server. A description of the minimum setup required to operate is also provided. A full listing of all settings on the internet/print server is provided in Chapter 5. Note that the settings and their options are the same regardless of whether you are using Telnet or a web browser although they are displayed in different formats.

Usage Note: Throughout this user’s guide, we refer to

“your ISP.” An ISP (Internet Service Provider) is a company that provides internet services for a fee, usually via modems connected over telephone lines. From the ISP’s point of view, the internet server is a single user (with a single username and password).

Internet Server Setup20

Setting IP Addresses

The IP address settings, which include the IP address, subnet mask and gateway IP address are the first and most important settings that need to be configured. The internet server comes with a default Local LAN IP address and subnet mask assigned. If you do not have a preexisting IP network and are setting one up now, using the factory default IP address settings can greatly ease the setup process. If you already have a preexisting IP network, you should adjust the IP settings for the internet server to fit within your existing scheme. Both cases are discussed below. Before proceeding, please make sure that you have physically connected all components in the LAN, including the internet server, the hub or switch and the computers, as described in the previous chapter.

Using the Default Address

The internet server comes with a preset default IP address setting of

192.168.100.1. There are two ways to use this default IP address. The first way is to manually set the IP address, subnet mask and default gateway on each computer. Different operating systems and network software suites will have a different procedure/application for setting the system IP. In Windows 3.1 and 3.11, find the TCP manager and choose TCP/IP then “Setup”. In Windows 95/98, click on the START button and choose Control Panel. In the window that opens, double-click on the Network icon. Under the Configuration tab, find or add a TCP/IP component and edit the address settings accordingly.

192.168.100.1 255.255.255.0

Server Computer #1 192.168.100.2 255.255.255.0 192.168.100.1 Computer #2 192.168.100.3 255.255.255.0 192.168.100.1 Computer #3 192.168.100.4 255.255.255.0 192.168.100.1

Please note that when using the default IP address as in the above example, the first three numbers in the IP address must always be the same with only the fourth number changing. This is because the first three numbers define the network IP address (all machines must belong to the same IP network), while the last number denotes the host address (each host must have a unique number). Also note that the subnet mask is the same for all machines and the default gateway address is the Local LAN IP address of the internet server.

The second way to use the default settings is to allow the internet server to automatically assign IP addresses to your computers using DHCP. To do this, simply make sure your computers’ IP addresses are set to 0.0.0.0. Under Windows, choose the option ‘Obtain an IP address automatically’ in the TCP/IP network component described above. When your computer is restarted, it will automatically be given a valid IP address, subnet mask and gateway address by the internet server. For this option to work, the internet server’s DHCP feature must be enabled, which it is by default.

Internet Server Setup22

Using Your Own Address Settings

If your LAN is already setup for IP networking and you wish to change the IP address of the internet server to operate within your existing IP network, simply:

1. Physically connect the internet server to your LAN and power it on.

2. Configure one computer on your network to have the IP address of

192.168.100.2 (or any unique IP address in the 192.168.100.XXX domain) and a subnet mask of 255.255.255.0. Please note the original IP settings of the computer before changing them. Restart the com puter.

3. Run Telnet and connect to the internet server through its default address of

192.168.100.1.

4. When prompted for the password on the opening screen, press the <Enter> key. There is no default password.

5. In the Main Menu choose System Configuration.

6. In the System Configuration window choose Local LAN -> IP Address and type in the IP address you wish to assign to the internet server.

7. Also in the System Configuration window choose Local LAN -> Subnet Mask and enter the correct subnet mask. Hint: If left blank, the internet server will automatically assign the standard subnet mask for Class A, B or C IP addresses.

8. Press to return to the main menu.

9. Press to Save Configuration settings. The internet server will automatically save the new settings and reboot, disconnecting your telnet session. When it comes online again, the new settings will be in effect.

10. Change the IP address and subnet mask of the computer back to their original configuration. Reboot the computer.

We recommend that you make a note of each device’s IP address for reference during troubleshooting or when adding new stations or devices.

Using Telnet to Configure the Server

Once your PC is configured with an IP address on the same subnet as the server, start your Telnet program and enter the IP address assigned to the server when you are prompted for a host address.

You should immediately see the internet/print server Telnet Interface console greeting screen.

Enter the password to access the device parameters. There is no default password. Once you have access, use the menu item numbers to set the settings which are described later in this chapter.

Internet Server Setup24

Note: When using Telnet to modify device pa-

rameters, saving those parameters immediately ends the Telnet session.

Using a Browser to Configure the Server

Once your PC is configured with an IP address on the same subnet as the server, start your browser program and enter the “http://” prefix, followed by the IP address assigned to the server, in the address window.

Internet Server Setup 25

Internet/Print Server User’s Guide

You should immediately see the internet/print server web browser interface menu. Note that the internet/print server IP can be bookmarked for future access so that it doesn’t need to be entered each time.

The browser interface uses frames, so it is best if you use a framescapable browser program. Also, we advise you to temporarily suspend the use of proxies – if you are using them – while accessing the internet/print server as proxy settings may interfere with browser access to local devices.

If you use a non-frames browser, when you receive the initial internet/print server screen, you should see the main navigation menu rather than the navigation menu and the system status screen. The functions are the same, only the appearance will be different.

After you have access to the browser interface, use the menu options in the left-hand frame to choose the settings you want to view, set or modify. Some settings have limited options that must be selected from a pull-down list.

Minimum Configuration

Regardless of how you intend to use the internet/print server, you will need to consider and set some basic system settings. This section is concerned with describing only those settings that are critical to proper functioning of the internet/print server.

The following settings need to be configured for the internet/print server to operate correctly (the first is a System setting, the others are WAN port settings):

Internet Server Setup26

DNS IP Address

Domain Name Service (DNS) servers are used on the internet to maintain information about which Uniform Resource Locator (URL) name relates to which internet IP address. For example, the URL: WWW.CNN.COM, is a pseudonym for the IP address: 207.25.71.25. DNS entries allow users to access resources using URLs instead of IPs.

Options: Any internet DNS server IP address available

through the WAN connection. This address should be provided by your ISP. (Note that without a DNS server IP, internet sites will only be available using IP addresses and will not be available using URLs.)

Default Value: 0.0.0.0 Must Be User Modified? Yes.

Description: A Domain Name Service (DNS) server address is used to translate URLs into their corresponding IP addresses.

ISP Account -> Phone Number

In order for the internet/print server to control the modem to dial the phone, you must enter the dial-up phone number for your ISP. If you need to dial an area code in order to call the number, it must be included in this setting. If you must dial “#”, 0, 9 or some other number in order to get an outside phone connection, that information must be included in how this setting is configured.

Options: For dial-up connections, the local ISP phone num-

ber, complete without spaces, hyphens or other punctuation (commas may be used to indicate a pause). The maximum length is 20 characters.

Internet Server Setup 27

Internet/Print Server User’s Guide

Example: Your ISP phone number is a local call to 916-5555

and you must dial 0 in order to get an outside line from the office where you want to use the internet/print server. You would enter 0,,9165555 in the “ISP Account -> Phone Number” setting. The two commas instruct the modem to pause between dialing the 0 and dialing the rest of the number. This pause is necessary if there is normally a moment or two between dialing 0 and getting an outside dial tone.

Default Value: (none) Must Be User Modified? Yes. Description: The phone number entered in this setting is

the number the internet/print server will dial to establish its internet (WAN) connection.

Note: If the ISP phone line is busy, the inter-

net/print server will automatically redial. Three successive redial attempts will be made.

ISP Account -> User ID

Just as the internet/print server needs to know what phone number to dial to access your ISP, it also needs to know what username to login under. This setting is the username the ISP has assigned to you or your company.

Options: Needed for dial-up connections. The ISP assigned

user ID name exactly as provided (i.e., all letters capitalized where necessary, underscores and other punctuation included). The maximum length is 64 characters.

Default Value: (none)

Internet Server Setup28

Must Be User Modified? Yes. Description: This setting is the user ID that will be pro-

vided to the ISP once the modem connection is established.

Notes: It may not be possible with some ISPs to use this set-

ting to allow the internet/print server to automatically login. In that case, it will be necessary to use the Login Script as described below.

ISP Account -> Password

The password is the final step in the ISP dial-up login process. As with the username, this password should have been assigned to you by your ISP when you registered for the service.

Options: For dial-up connections, the ISP user access pass-

word exactly as provided (i.e., all letters capitalized where necessary, underscores and other punctuation included). The maximum length is 32 characters.

Default Value: (none) Must Be User Modified? Yes. Description: This setting is the user password that will be

provided to the ISP once the modem connection is established and the username has been accepted.

Notes: It may not be possible with some ISPs to use this set-

ting to allow the internet/print server to automatically login. In that case, it will be necessary to use the Login Script as described below.

Internet Server Setup 29

Internet/Print Server User’s Guide

The login script allows you to list prompts generated by the ISP each time a user dials-up and then provide the right responses so that the internet/print server can login. The login script should be used when the Username and Password settings above don’t work with your ISP or if your ISP’s login procedure includes additional prompts (for example, a transmission protocol choice).

Options: For each line item, a prompt string and a keyin

string must be provided. The prompt string is the text displayed by the ISP requesting that something be entered. The keyin string is what should be entered. Prompt strings can be up to 25 characters long including punctuation. Keyin strings can be up to 20 characters long including punctuation (a maximum of 8 separate line entries).

Example: If your ISP asks you to input a user ID, password,

and to choose from a list of available communications protocols each time you dial-up, your login script would look like something like this:

No. Prompt Keyin 1 Username Stepanka 2 Password abcd 3 Choice --> 2 With each prompt being the text of the prompt provided by the

ISP, and each keyin being the exact data you would enter.

Default Value: (none) Must Be User Modified? No (unless your ISP login proce-

dure requires you to use a login script).

Internet Server Setup30

Description: A login script is used to provide login prompt

responses when required by the ISP login procedures. Each line item in the script table should correspond with a prompt that the ISP makes once the modem connection is established. The prompt string information entered in the table should include an indication of what data is being asked for at each step in the login process. Reply string data should be provided exactly as it would be if it were hand entered.

Operation

To access the internet, do the following at each station that will use the internet/print server for internet access:

1. Make sure that TCP/IP settings are configured properly. IP pa-

rameters that must be set include:

• IP Address – must be a unique IP address chosen from the

three reserved IP ranges set aside for local network only use. See “Setting IP Addresses” earlier in this chapter.

• Default Gateway – should be set to the IP address assigned

to the internet/print server’s LAN interface.

• DNS (Domain Name Service) – an IP address provided by

your ISP.

2. Activate your browser and use normally.

PRINT SERVER SETUP

This chapter explains how to use the internet/print server as a network print server.

Print Server Features

Print servers improve network printing services in three ways: ♦ They pick up the workload of managing print file traffic to

connected printers. This provides workload relief to file servers, and allows the file servers’ full capacity to be used for file access or other direct services to network users.

♦ The internet/print server’s IEEE 1284 compliant, high-speed,

bi-directional parallel printer port can transmit to high-speed laser printers much faster than a PC's parallel printer port. A high-speed laser printer can thus be used at its full capacity.

♦ Because the internet/print server is very portable and inexpen-

sive compared to a PC-based print server, the printer can be stationed at the location of maximum convenience to users.

The internet/print server’s print server functionality offers extraordinary flexibility, operating with most major network operating systems and protocols:

Print Server Setup32

♦ TCP/IP UNIX lpr/lpd (HP-UX, SunOS, Solaris, SCO, UnixWare, IBM

AIX); Windows NT

♦ NetBEUI Windows NT, Windows 95/98, Windows for Workgroups, Micro-

soft LAN Manager, IBM LAN Server

♦ AppleTalk MacOS EtherTalk

The print server configuration, features, and operation can all be controlled using the same Telnet or browser interface as the WAN port and other aspects of the internet/print server (see the next chapter).

Connecting the Print Server

To connect your printer to the internet/print server, you should use the standard parallel cable that comes with the printer. If you need to purchase a new parallel cable, be certain that the connectors on both ends of the cable are the right type and that the total cable length does not exceed 12 feet (approximately 4 meters).

Follow these steps for a trouble-free print-server connection.

1. Confirm proper operation of the printer to be connected to the

internet/print server.

2. When you have confirmed proper operation of the printer,

switch its power off.

Print Server Setup 33

Internet/Print Server User’s Guide

3. Confirm that your network is operating normally.

4. Connect the internet/print server to the network (through the

RJ-45 port on the print server’s rear panel).

5. While the printer is powered off, install a printer cable to con-

nect its parallel port to the printer port of the internet/print server.

6. Switch printer power on.

7. Plug the AC power adapter’s output plug into the power input

socket on the rear panel of the internet/print server.

8. Plug the AC power adapter into an electric service outlet. This

will supply power to the internet/print server. (The server has no power switch).

Description: The AppleTalk print protocol requires that

shared postscript printers be identified as to whether they are Level 1 or Level 2 postscript.

AppleTalk -> Font Group

Options: No font, All fonts, Standard 35, Standard 13 Default Value: Standard 35 Description: The AppleTalk print protocol requires that

shared postscript printers be identified as to what font group is supported by the printer. Most postscript printers support Standard 35 (Adobe 35N font set). The option, “No font” will force Macintoshes to load fonts to the printer, and the option, “All fonts” will prevent Macintoshes from loading any fonts to the printer.

DHCP Server Configuration

The Dynamic Host Configuration Protocol (DHCP) allows servers and devices like the internet/print server to dynamically assign IP addresses to network devices. Dynamic IP assignment alleviates the need for the network administrator to maintain and monitor IP address assignments and simplifies IP use because IP address are automatically and dynamically assigned when a station powers-on. DHCP is factory defaulted to ON.

Important Note: If you use DHCP to set your local

IP addresses, the software IP settings of all stations on the network will need to be manually configured to 0.0.0.0., or, as in the case of Windows 95/98 users, the “Obtain

Configuration Settings 49

Internet/Print Server User’s Guide

an IP address automatically” option under TCP/IP will have to be selected.

Enable

Options: Yes/No Default Value: Yes Description: This setting is the “on/off” switch for using a

DHCP server. DHCP (Dynamic Host Configuration Protocol) allows IP addresses to be dynamically assigned. Rather than assigning a specific local IP address to each station, the internet/print server will assign IPs to each station dynamically if the DHCP server function is enabled.

IP Address Range -> Start

The range of IP addresses available to the internet/print server for DHCP allocation is set using two settings. This is the first.

Options: Any IP address within the three reserved IP

ranges. The IP chosen must correlate with the End of the range.

Default Value: 192.168.100.101 Must Be User Modified? No. Description: This setting indicates the beginning of the

range of IP addresses available for DHCP use in assigning IPs. It is paired with the next setting to create an address range.

Configuration Settings50

IP Address Range -> End

This is the second of the DHCP IP address range settings. Options: Any IP address within the three reserved IP

ranges. The IP address used must correlate with the IP set in the Beginning range setting.

Default Value: 192.168.100.150 Description: This setting indicates the end of the range of

IP addresses available for DHCP use in assigning IPs. It is paired with the previous setting to create an address range.

IP Lease Time

Options: An amount of time, measured in minutes, from 5 to

65535.

Default Value: 1440 (24 hours) Description: Dynamically assigned addresses can be peri-

odically “refreshed” by a DHCP server. The IP Lease Time setting allows you to set that time limit. If a time is entered in this setting, each dynamically assigned address will be recycled at the end of the lease time.

IP Reserve Table

Options: Local IP Address, MAC Address (a maximum of 16

separate line entries).

Default Value: (none) Description: The IP reserve table specifies ownership of par-

ticular IP addresses by particular stations or servers

Configuration Settings 51

Internet/Print Server User’s Guide

(identified by MAC address) so that those IP addresses will not be used by other devices on the LAN under any circumstances. (Note that devices listed in the Server Address Settings table should have their IP addresses listed here if DHCP is going to be used so that their IP addresses don’t get assigned to other network stations.)

Server Address Configuration

The Server Address Configuration table allows you to setup local servers, for example an FTP or web site, and provide non-local access to them through the internet/print server. Entries in the table associate a port number with the local IP of a particular LAN server so that users not on the LAN can access that server.

The internet/print server supports virtual internet servers so that your single-point ISP internet access can be used to provide externally-accessible servers for FTP and HTTP. “Virtual Servers” in this context are “virtual” because they don’t have their own public domain IP addresses in the typical internet fashion. Rather, their local IP address, with an access port number, is listed in a table inside the internet/print server. The port number provides the internet/print server with the reference to correctly route data requests.

Note that in LAN-to-LAN mode, this function is disabled and no LAN devices can be accessed from the internet.

♦ No.

Item number used for entry editing. Maximum of 16 en-

tries.

♦ Local IP Address

Configuration Settings52

The LAN IP address for the server entered. Any resource

which will be shared to the internet through the server should have a dedicated IP address.

♦ Protocol

The type of server protocol being used: TCP or UDP

♦ Port Number

Configuration Settings54

A table showing all the hours in all the days of the week. Choose Add to add a period of time to the table during which the internet server can dial out.

♦ Holiday Table

The holiday table is used to create exceptions to the

schedule table. The holiday table lists all 12 months. Choose Add to add a date to the holiday table. Any dates designated in the holiday table will keep the internet server from dialing out on that day. The Holiday table is only enabled when scheduling is enabled.

♦ Dial Up Mode

In normal operation (when scheduling is disabled) the

internet server will always dial out when it receives a data packet destined for the internet, and will hang up when the idle time condition in the System Configuration menu is met. However, when scheduling is enabled, the internet server will maintain the WAN connection according to these parameters:

• Auto Dial – Causes the internet server to auto-

matically dial out when a scheduled time occurs. If the internet server is scheduled to operate between 9:00 am and 17:00 pm on Mondays, then at 9:00 am Monday morning the internet server will dial out regardless of whether it receives a packet destined for the internet. The connection to the internet will be maintained until the scheduled period elapses.

• Dial on Demand – Causes the internet server to

dial out when it receives a packet for the internet, if the packet is received within the time allowed for dialing up in the schedule table. If a request is received to access the internet outside of the time

Configuration Settings 55

Internet/Print Server User’s Guide

limits defined in the schedule table, the internet server will not dial out.

Routing Table

The static routing table allows the internet server to coexist on the same network with a router. This implementation depends on whether the router has its own WAN access to the internet.

If the router does not have a connection to the internet, then you do not need to create a new IP network or IP subnet. You simply need to add the internet server to the existing LAN and configure the router to use the Local LAN IP address of the internet server as its default gateway. In the internet server, you must add static routes into the routing table to the other IP networks or IP subnets that the router is routing between. Use the router’s LAN IP address as the gateway for the static routes to the other IP networks or IP subnets that the internet server does not belong to. Doing this enables computers on the same IP network as the internet server to communicate with the computers on the other local IP networks or IP subnets.

If your router has its own connection to the internet then you must create a new IP network or IP subnet. All computers on the new IP network will use the internet server to access the internet. Computers remaining on the preexisting IP network will continue to use the router for internet access. In this configuration, the internet server can ease the burden for internet bandwidth on the router. However, for computers on the new IP network to communicate with computers on the old one, you must create a static route in the internet server’s routing table. When doing this, the IP address of the static route will be the preexisting IP address and the gateway will be the LAN port of the router.

Configuration Settings56

Note: If you are creating a second IP network, do not allow

the internet server to use DHCP if the router is also using DHCP, unless the router is supplying IP addresses on only one port and the internet server is not connected to that port.

Filter NetBIOS over TCP/IP

As the name states, this feature allows you to filter NetBIOS traffic when it is transmitted over TCP/IP. This can prevent NetBIOS packets, domain name queries for example, from initiating a dial-up connection.

Display Information

The internet/print server provides a display function which shows the current setting and operational status of all of its functions. In display mode, it is only possible to view the status of settings and functions, it is not possible to modify or control them.

Displaying Information

TROUBLESHOOTING

System POST

When the unit is powered on, the system first runs a Power-On Self Test (POST) as a check of system components. Errors encountered during the POST are indicated by different flashing front panel LED combinations.

Note: The LEDs flash as a normal part of the

system initialization. The error flash codes listed in the table below will be constant and thus unlike the brief LED indications at initial power-on.

Device Installation Problems

WAN

IP ADDRESSES: If you have trouble connecting with or contacting

your ISP, double-check the IP address setting of the internet/print server. Particularly if your ISP is not using DHCP to dynamically assign IP addresses, make certain that you are using the right IP for the login you have set.

ACCESS PASSWORD: It is possible that you mis-entered your

ISP login password. Use the Telnet or browser configuration program to re-enter the login password.

Troubleshooting 61

Internet/Print Server User’s Guide

Print Server

UNSUPPORTED PROTOCOL: The internet/print server sup-

ports the TCP/IP, NetBEUI, and AppleTalk print protocols. If your network is using some other print protocol (NetWare IPX/SPX for example), you will have printing problems. Most platforms should allow you to reconfigure and use a supported protocol.

LAN

IP ADDRESSES: If stations on your network have trouble connect-

ing with the internet, double check their IP address settings. Particularly if you are not using the internet server’s DHCP server function, make certain that you are using only IP addresses from the three reserved ranges and that each PC’s IP address is within the same subnet as the internet server LAN IP.

Station Configuration Problems

SUSPEND BROWSER PROXIES: When using a browser to con-

figure the internet/print server, we recommend that you suspend use of proxies until after you have completed the configuration. If you are using a proxy server on a different subnet, your browser will have difficulty contacting the internet/print server.

IP ADDRESSES: The PC you are using must have an IP address

on the same subnet as the internet/print server in order to contact it.

Troubleshooting62

Operating Problems

ISP LOGIN PROCEDURES – LOGIN SCRIPT: It may be neces-

sary for you to create login script entries in order to complete your login procedure. Some ISPs prompt for a communications protocol choice or other data after a successful modem connection. Refer to Chapter 5 for more information.

MODEM COMMANDS: It may be necessary for you to reconfigure

the initial modem commands due to operational differences in your modem. Refer to Appendix C of this User’s Guide and the documentation provided with your modem for more information. In particular, check the setting of the initial string for discrepancies with your modem’s operational features.

ISP DETAILS: Double check all ISP login information (i.e., user-

name, password, phone number) for accuracy.

OUTSIDE LINE ACCESS DIALING: If it is necessary for you to

dial a special number in order to dial a phone number outside of your office, that dialing information will need to be included in the phone number information provided to the internet/print server. See Chapters 3 and 5 for more information.

NUMBER OF USERS: While the internet/print server can handle

any number of users, it is recommended that no more than 50 attempt to access the internet through the device simultaneously. Note that the more people who access the internet through the internet/print server the slower response times will be for all.
