Introducing the NPS-520

This chapter introduces the main applications of the NPS-520. It also introduces the ways you can manage the NPS-520.

1.1 Overview

The NPS-520 (labeled NPS in the following graphic) is a print server that allows the computers in a network to share a printer, especially a multi-function printer (MFP). A MFP is a printer that can also work as a scanner, fax machine, copy machine, card reader and so on. The NPS-520 has one USB port and one Ethernet port. If a MFP comes with a USB port but no Ethernet port, the NPS-520 allows you to connect the MFP to your network and provides users on the network with shared access to the printer.

Figure 1 Application Overview

Windows 2000 SP4 and later computers connected to the NPS-520 can use all features available on an MFP, such as copying, printing, scanning and so on. They should also support LPR (Line Printer Remote) or IPP (Internet Printing Protocol). Other computers connected to the NPS-520 can only use the printer to print. Computers must take turns using the printer.

1.2 Ways to Manage the NPS-520

Use any of the following methods to manage the NPS-520.

•ZyXEL Utility. The utility is a tool that helps you configure the NPS-520 in a Windows computer.

•Web Configurator. You must use the web configurator if your are using a Linux/UNIX or Macintosh computer.

NPS-520 User’s Guide

Chapter 1 Introducing the NPS-520

1.3 Good Habits for Managing the NPS-520

Do the following things regularly to make the NPS-520 more secure and to manage the NPS520 more effectively.

•Change the password. Use a password that’s not easy to guess and that consists of different types of characters, such as numbers and letters.

•Write down the password and put it in a safe place. If you forget your password, you will have to reset the NPS-520 to its factory default settings.

1.4Hardware and Utility Installation

Follow the instructions in the Quick Start Guide to make hardware connections and install the ZyXEL utility.

1.5 The Reset Button

If you forget the password and cannot access the ZyXEL utility’s TCP/IP Setting and System Setting screens or the web configurator, you will need to use the Reset button on the side of the NPS-520. This means you will lose all configurations that you had previously. The password will be reset to 1234 and the IP address will be reset to 192.168.1.6.

1Make sure the Ready LED on the NPS-520’s panel is on (not blinking).

2Press the Reset button for more than five seconds and then release it.

3The Ready LED is off when you press the button. Then the Ready and Status LEDs flash once.

4When the Ready LED turns steady on, the defaults have been restored and the NPS-520 is ready.
