CHAPTER 1

Introducing the Zyxel Device

1.1 Overview

Zyxel Device refers to these models as outlined below.
• AX7501-B0 • DX5401-B0 • EX5401-B0
• DX3300-T0 • EX3300-T0 • EX5501-B0
• DX3301-T0 • EX3301-T0 • PX7501-B0
• DX5301-B2 • EX5300-B3
• DX5301-B3 • EX5301-B3
The AX7501-B0 is an AON (Active Optical Network) while the PX7501-B0 is a PON (Passive Optical Network) router. They provide fast Internet access. They both have one 10 Gbps Multi-Gigabit Ethernet LAN port and four 1000 Mbps Ethernet LAN ports.
The DX3300-T0, DX3301-T0, DX5301-B2, DX5301-B3, and DX5401-B0 are DSL routers, which provide fast Internet access over telephone lines. They also support WiFi6 that is most suitable in areas with a high concentration of users. You can schedule WiFi usage using Parental Control.
The EX3300-T0, EX3301-T0, EX5300-B3, EX5301-B3, EX5401-B0 and EX5501-B0 are Ethernet gateways which provide fast Internet access. The EX5501-B0 has 2.5 Gbps Multi-Gigabit Ethernet (GbE) WAN ports that are backward compatible with standard Gigabit speed. See Section 1.1.1 on page 20 for more information on Multi-Gigabit Ethernet.
The Zyxel Device also has one USB port that can be configured as a backup WAN port in case the Cellular/Fiber connection has a problem as well as for file sharing and as a media server.
The following table describes the feature differences of the Zyxel Device by model.

1.1.1 Multi-Gigabit Ethernet
A 2.5 Gigabit Ethernet port supports speeds of 2.5 Gbps if the connected device supports 2.5 Gbps. While a 10 Gigabit Ethernet port supports speeds of 10 Gbps if the connected device supports 10 Gbps and a Cat 6a (up to 100 m) or Cat 6 cable (up to 50 m) is used.
EX5501-B0PX7501
-B0
Some network devices such as gaming computers, servers, network attached storage (NAS) devices, or access points may have network cards that are capable of 2.5 Gbps or 5 Gbps connectivity.
If these devices are connected to a 1 Gbps or 10 Gbps Ethernet port, they can only transmit or receive up to 1 Gbps as speeds of 2.5 Gbps / 10 Gbps cannot be attained. Moreover, if network devices with 2.5 Gbps / 10 Gbps network cards are connected to a 2.5 Gbps / 10 Gbps Ethernet port, you must use Cat 5e / Cat 6A or better Ethernet cables to achieve 2.5 Gbps / 10 Gbps speeds. Most buildings, at the time of writing, use Cat 5e or Cat 6 Ethernet cables.
Multi-Gigabit Ethernet ports automatically allow connections up to the speed of the connected network device (100 Mbps (not supported on EX5501-B0), 1 Gbps, 2.5 Gbps or 5 Gbps), and you just need to use a Cat 5, Cat 5e or Cat 6 Ethernet cable.
See the following table for the cables required and distance limitation to attain the corresponding speed.
Table 3 Ethernet Cable Types
CABLE TRANSMISSION SPEED
Category 5 100 Mbps 100 m 100 MHz
Category 5e 1 Gbps / 2.5 Gbps / 5 Gbps 100 m 100 MHz
Category 6 5 Gbps / 10 Gbps 50 m 250 MHz
Category 6a 10 Gbps 100 m 500 MHz
Category 7 10 Gbps 100 m 650 MHz

1.2 Example Applications

This section shows a few examples of using the Zyxel Device in various network environments. Note that the Zyxel Device in the figure is just an example Zyxel Device and not your actual Zyxel Device.
AX/DX/EX/PX Series User’s Guide

1.2.1 Internet Access
The AX7501-B0, PX7501-B0, DX5401-B0 and EX5401-B0 provides shared Internet access by connecting a fiber cable provided by the ISP to the FIBRE port. It supports OMCI (ONU Management and Control Interface) to connect to the ISP’s OLT (Optical Line Terminal).
The DX3300-T0, DX3301-T0, DX5301-B2/B3 and DX5401-B0 provide Internet access by connecting the WAN port to your ISP through DSL cables.
The EX3300-T0, EX3301-T0, EX5300-B3, EX5301-B3 and EX5401-B0, EX5501-B0 provide Internet access by connecting the WAN port to your ISP through Ethernet cables.
Computers can connect to the Zyxel Device’s LAN ports (or wirelessly) and access the Internet simultaneously.
Figure 1 Zyxel Device’s Internet Access Application
Chapter 1 Introducing the Zyxel Device
You can also configure Firewall on the Zyxel Device for secure Internet access. When the Firewall is on, all incoming traffic from the Internet to your network is blocked by default unless it is initiated from your network. This means that probes from the outside to your network are not allowed, but you can safely browse the Internet and download files.
Connect the WAN port to the broadband modem or router. This way, you can access the Internet through an Ethernet connection and use the QoS, Firewall and parental control functions on the Zyxel Device.
Figure 2 Zyxel Device’s Internet Access Application: Ethernet WAN
1.2.2 Dual-Band WiFi
By default, WiFi is enabled on the Zyxel Device. IEEE 802.11a/b/g/n/ac/ax compliant clients can wirelessly connect to the Zyxel Device to access network resources.
AX/DX/EX/PX Series User’s Guide
21
Chapter 1 Introducing the Zyxel Device
The Zyxel Device is a dual-band gateway that can use both 2.4G and 5G networks at the same time. You could use the 2.4 GHz band for regular Internet surfing and downloading while using the 5 GHz band for time sensitive traffic like high-definition video, music, and gaming.
Figure 3 Dual-Band Application
The Zyxel Device is a wireless Access Point (AP) for IEEE 802.11b/g/n/a/ac/ax wireless clients, such as notebook computers, iPads, smartphones, and so on. It allows them to connect to the Internet without having to rely on inconvenient Ethernet cables.
Your Zyxel Device supports WiFi Protected Setup (WPS), which allows you to quickly set up a wireless network with strong security.
Figure 4 Wireless Access Example
1.2.3 VoIP Applications
The Zyxel Device’s VoIP function allows you to register up to two SIP (Session Initiation Protocol) accounts and use the Zyxel Device to make and receive VoIP telephone calls. The Zyxel Device sends your call to a VoIP service provider’s SIP server which forwards the calls to either VoIP or PSTN phones.

1.3 Ways to Manage the Zyxel Device

Use any of the following methods to manage the Zyxel Device.
• Web Configurator. This is recommended for management of the Zyxel Device using a (supported)
web browser.
• Simple Network Management Protocol (SNMP). Use to monitor and/or manage the Zyxel Device by
an SNMP manager.
• Secure Shell (SSH), Telnet. Use for troubleshooting the Zyxel Device by qualified personnel.
• FTP. Use FTP for firmware upgrades and configuration backup or restore.

1.4 Good Habits for Managing the Zyxel Device

Do the following things regularly to make the Zyxel Device more secure and to manage the Zyxel Device more effectively.
• Change the WiFi and Web Configurator passwords. Use a password that is not easy to guess and that
consists of different types of characters, such as numbers and letters.
• Write down the passwords and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it). Restoring an earlier working
configuration may be useful if the device becomes unstable or even crashes. If you forget your password, you will have to reset the Zyxel Device to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the Zyxel Device. You could simply restore your last configuration.
