CHAPTER 1
Introducing the Zyxel Device
1.1 Overview
Zyxel Device refers to these models as outlined below.
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.
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.
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.
