2.2 Description

The Patton Model 2126 PeNetTM Print Server supports multi-

protocol printing in both Novell and TCP/IP LANs, and is fully compliant

to the ANSI/IEEE 802.2 and 802.3 Standards. Able to recognize up to

250 servers, the Model 2126 can simultaneously logon to ten of them. If

the network moves and changes frequently, the Model 2126 can also

be configured to continuously scan and log on to new servers.

In case of power loss, the Model 2126 can restore connection to

servers that are downed. It also supports all the Novell printing and

print server features. The PeNetTM supports print speeds greater than

60,000 bytes per second. Configuration is accomplished using a Novell

compatible utility. (For TCP/IP environments, configuration is

accomplished via Telnet sessions.) FLASH EPROM allows upgrades to

be done efficiently through the network.

3.0 INSTALLATION

The PeNetTM Print Server is easily installed on a Novell and/or

TCP/IP network using standard Coax cabling. The following section of

this manual describes the installation procedure required. It is highly

recommended that you follow the instructions provided to ensure a

simple and trouble free installation. Note: Please read the file named

“readme.doc” on the enclosed 3.5” hard diskette.

3.1 Checking The Supplied Parts

Unpack the unit and check that the following items have been

supplied:

1. PeNetTM Print Server

2. 5v DC wall mount power adapter

3. This Manual

4. Software utilities diskette (contains UCONNECT utility)

If any of these items are missing, then contact your supplier

immediately.

3.2 Physical Connection and Operation

The PeNetTM Print Server is straightforward to connect and operate.

As Figure 1(below) illustrates, the rear panel of the Print Server

incorporates an external power supply connection, one coaxial

connector, a Link Status LED and a Power LED. (The Centronics

connector on the front of the Print Server plugs directly into a standard

parallel printer port.)

(Continued)

Figure 1. Print Server Rear Panel

External Power Jack BNC Connection Link Status LED

Power LED

Follow the steps below to connect the Print Server to the printer and

network (the order is not critical):

1. Connect the required network cable (10Base2) to the modular

connector on the Print Server (The Link Staus LED will not glow

until power has been applied to the Print Server.)

2. Plug the power supply adapter into the jack on the rear of the Print

Server and then into a (surge protected) AC wall outlet.

When sufficient power is applied to the Print Server (external or

interface power), the Power LED will glow and the Print Server will

boot up. The Link Status LED should also glow, since you have

presumably accomplished Step 1 already.

3. Immediately after performing steps 1 & 2, connect the Print Server

directly to the parallel port of the printer and turn the printer ON (if it

is not already ON)

Approximately 15 - 30 seconds after booting up, the Print Server will

spool a status page to the Centronics port. If you have connected

the Print Server to the printer and turned the printer ON within that

time frame, the status page should print. The status page shows

the unit’s current operating parameters and proves that a good

printer connection exists.

What if a status page does not print after 15 - 30 seconds?

a) If you did not connect to (and turn ON) the printer right away, it is

possible that the Print Server spooled a status page

before

the

printer could respond. Disconnect and reconnect power to the Print

Server. This will reboot the print server and spool another status

page.

b) Is your printer set up for Postscript? If so, this will interfere with

the

default

set-up of the Print Server. The status page may be

garbled or may not print at all. See Section 4.8 on General

Troubleshooting.

c) If your printer has a large buffer, the printing of the status page

may depend on the timeout setting within your printer. It may take a

few minutes for a large print buffer to timeout and print.

Note: Some printers are able to supply 5 V DC (TTL Spec.) on

pin 18 of the Centronics connector. If your printer is one

of these, you may not need the AC power adapter.

3.3 Installing UCONNECT on a Workstation

UCONNECT is the configuration utility that is supplied with the

Print Server. UCONNECT allows the Print Server to be installed on a

Novell network, and will run on any Novell compatible workstation.

(Note: Both Novell and TCP/IP parameters can be configured using

UCONNECT. However, you cannot run a TCP/IP session in

UCONNECT. See Section 5.0 for more information.)

UCONNECT is supplied on a PC-DOS diskette. For your

convenience, we recommend that you copy the utility (file name

UCONNECT.EXE) to your workstation hard drive. The transaction

might look something like this:

MD C:\UCONNECT

(insert diskette into drive A)

COPY A:\*.* C:\UCONNECT

Once the utility program has been copied to the hard drive, type

UCONNECT at the DOS prompt and press [ENTER] to execute the

utility.

(Continued)

STOP! If you are connecting the Print Server to a TCP/IP

network that is

not

Novell based, go immediately to Section 5.0

TCP/IP Operation. If you are connecting the Print Server to a

Novell network, or to a Novell network running TCP/IP, continue

on to Sections 3.4 and 4.0.

3.4 Using PCONSOLE

PCONSOLE is a Novell supplied utility for setting up Print Queues

and Print Servers. Before it is possible to print using the Print Server

unit, it will be necessary to use PCONSOLE to inform Novell of the

presence of a new Print Server and to create/attach print queues to this

Print Server. You will require Supervisor privileges to create a new

Print Server and Queue.

Run PCONSOLE from the command prompt on a workstation and

the following screen will appear:

From the Available Options Menu select Print Server Information. This

will display a list of currently available Print Servers. Press the INSERT

key and enter the name you allocated to the PeNetTM Print Server unit

(Units LOGIN Name) within the configuration procedure explained

earlier. Press ENTER to inform Novell of the newly installed device.

Once this new Print Server is displayed in the list of available Print

Servers, select it by hi-lighting it using the cursor keys and then

Stop! Before running UCONNECT, check the following Novell

operating system parameters. If you are unfamiliar with any of

them, consult your Novell manual or contact your Novell

Administrator.

1) Check that ‘Allow Unencrypted Passwords’ has been

set to ON

2) Ensure that the unit’s Name and Password are as

allocated in PCONSOLE

3) Check that there is a connection available for the Print Server

(use Monitor on the Server Console)

4) If Selective Login is enabled, ensure correct File Server

name(s) have been entered

5) Check that Novell Mode is not disabled

3.5 UCONNECT Commands

Once the UCONNECT utility has been copied to the hard drive,

type UCONNECT at the DOS prompt and press [ENTER] to execute the

program.

UCONNECT is a menu driven program. To work within the menus,

use the arrow keys to scroll up and down between menu items. The

[esc] key is a toggle switch used to select and deselect menu items to

be edited. The [ENTER] key is used to update the file and move to

another menu screen. Some screens have slightly different commands.

These are noted on the screen itself.

4.0 NOVELL OPERATION

This section tells how to use the Print Server with a Novell network.

Functions described include locating the Print Server on the network,

configuration, testing, printing, and FLASH EPROM upgrading. For

instructions on use of the Print Server within a TCP/IP network that is

not

Novell based, please refer to Section 5.0.

4.1 Locating the Print Server on the Network

The Print Server has a unique NIC Address that has been provided

by Patton Electronics with the approval of the ISO council (this NIC

Address has been marked on a label on the underside of the unit).

Before the Print Server can be configured, operated, tested or

upgraded, it must be located and recognized by the network. Using

the UCONNECT utility, follow these steps to locate the print server:

1) Having completed the instructions in Section 3.0, you should see the

Main Menu screen.

2) Select “Configuration” and press [ENTER]. This will take you to the

Specify Print Server Address screen (following page).

Note: the appearance of many of the screens will vary based

upon the configuration of your particular network. The

network component names show are examples only.

3) In the Specify Print Server Address Screen, select “Search Network

for Print Servers” and press [ENTER]. This will take you to the Selected

Networks screen.

4) The Selected Networks screen allows you to choose the networks

you want UCONNECT to search in order to locate the Print Server. Use

the arrow keys to scroll between lines. Use the [esc] key to select and

deselect networks. Press [ENTER] to update the file with your

selections and go to the Select Required Search Method screen.

5) The Select Required Search Method screen allows you to specify the

search path(s) that UCONNECT takes in order to locate the Print

Server. The first option will route the search through the file sever your

workstation is connected to. This will limit the search. The second

option will search all selected networks in a “broadcast” manner. (The

default is

both

methods.) Use the arrow keys to scroll between lines.

Use the [esc] key to select and deselect search methods. Press

[ENTER] to update the file with your selections and go to the next

screen. 11

6) The Start Scan for Print Servers screen allows you to initiate the

scan based upon the criteria you have chosen. Select an option using

[ENTER]. Choosing “yes” will begin the search. Choosing “no” will

take you back to the Main Menu.

Once your search has begun, UCONNECT will provide you with

screens updating you on the progress of the search. If you have

chosen to search through the local file server, you will see a display-

only screen that looks like the image below:

If you have chosen the broadcast search option, you will then see a

display-only screen that looks like the following image:

7) When the search is complete, you will see a list of the Print Servers

UCONNECT has located on the Available Print Servers screen (see

below). Use the arrow keys to scroll between listed servers, and the

[ENTER] key to select a single print server to configure.

8) When you have selected a print server to configure, you will see the

Password screen. Key in the password “PATTON” and press [ENTER]

to move to the Available Configuration Options screen.

9) The Available Configuration Options screen lets you select several

pathways of configuration depending upon the operating system your

network is using. Section 4.3 will give you an overview of the

configuration options so that you can custom-tailor the Print Server to

your own requirements.

4.2 Configuration within Novell using UCONNECT

UCONNECT lets you configure the Print Server to work with several

types of Novell compatible network operating systems. This section will

guide you through the various configuration options.

4.2.1 General Configuration

The first option on the Available Configuration Options screen lets

you key in general information that will apply to any operating system.

In most cases you will need to enter information in the General

Configuration Parameters screen, as well as a second screen that

applies more specifically to the particular operating system you are

using.

Each of the options on the General Configuration Parameters screen

can be edited using the arrow and [esc] keys to scroll and select.

1) The Configuration Password may be altered to suit your needs.

2) The Upgrade Password

may

be altered, but we recommend that

you leave this password unchanged.

3) You must change the Postscript Printer field to YES if your

printer uses Postscript. Otherwise, the printer will not output

correctly.

4) The Power up Status Page field may be changed to NO if you do

not want a status page to appear upon power up of the Print Server.

(continued)

4.2.2 Novell Configuration

The second option on the Available Configuration Options screen

lets you enter information to configure the Print Server to work in a

standard Novell environment. Any of these fields may be edited.

4.2.3 Advanced Novell Configuration

The third option on the Available Configuration Options screen is

“Advanced Novell”. This is UCONNECT’s alternative to the

PCONSOLE print queue utility. Advanced Novell lets you point a

particular print server to specific file servers and print queues. This is

done in two steps:

1) When you select the Advanced Novell option, you will be prompted to

supply a print server to configure. Use the arrow and [esc] keys to

scroll and select the print server you wish to configure. Then press

[ENTER].

2) Once you have selected a print server to configure, you will receive

the Advanced Novell Configuration screen, where you can point the

print server to particular file servers and print queues.

4.2.4 TCP/IP Configuration

The fourth option on the Available Configuration Options screen lets

you configure the Print Server to work in a Novell network running

TCP/IP. Remember: You cannot run a Unix session using

UCONNECT. See Section 5.0 for TCP/IP operation.

4.2.5 Personal Netware Configuration

The fifth option on the Available Configuration Options screen lets

you configure the Print Server to work with Personal Netware.

Warning! Contact your Novell Administrator if you are unfamiliar

with Novell setup procedures.

4.2.6 Reset to Factory Defaults

The sixth option on the Available Configuration Options screen

resets the Print Server to all Factory Defaults. If you select “Yes” on the

Reset Available Configuration Options screen, UCONNECT will reset

the Print Server and return you to the . If you select “no” on the Reset

screen, UCONNECT will return you immediately to the Available

Configuration Options screen.

4.2.7 Exit

The seventh option on the Available Configuration Options screen

exits to the Main Menu. However, you will exit directly to the Main

Menu only if you have made no changes to the configuration of the unit.

If you have made changes, you will be sent into the following sequence:

1) If you select Exit and you have made configuration changes, you will

next see the Send Changes screen. If you select “No” on this screen,

you will go immediately to the UCONNECT Main Menu and your

changes will not be saved. If you select “Yes”, you will receive a

timeout at the bottom of your screen while UCONNECT sends your

configuration changes to the Print Server. (Note: the changes you

entered will not take effect until the Print Server is rebooted.)

Warning! If you select “Yes” you will lose all changes you have

made in the configuration process.

2) After you have sent your configuration changes to the print server

and have seen a timeout at the bottom of your screen, you will then see

the Reboot screen. Selecting “Yes” on the Reboot screen immediately

reboots the print server and takes you to the DOS prompt. The

configuration changes you have entered will now be in effect. Selecting

“No” on the Reboot screen takes you immediately to the UCONNECT

Main Menu. Your configuration changes will then not take effect until

the next time the Print Server is rebooted.

4.3 Testing within Novell using UCONNECT

The UCONNECT utility may be used to test the Print Server in a

Novell environment. To access the Available Test Options screen,

perform the operation described in Section 4.2, choosing Test from the

Main Menu instead of Configure. When the screen appears, pressing

[ENTER] will cause the Print Server to print a status page, thereby

testing the setup. Choosing “Exit” will take you back to the DOS

prompt.

Reboot Print Server for Changes to Take Effect
