CHAPTER 1
Introduction
1.1 Overview
The PM7516-R0 is a Symmetric Passive Optical Network (XGSPON) Bridge Optical Network Terminals
(ONT) with one 10G Ethernet port.
1.1.1 Network Bridge
The Ethernet port on the Zyxel Device acts as a bridge. You can connect a switch or router to it. In the
example figure below, the service provider (OLT) uses one physical fiber line to provide service for the
Ethernet port on the Zyxel Device. The PM7516-R0’s Ethernet port provides a 10G service to the devices
behind a switch or router.
Figure 1 PM7516-R0 as a Network Bridge
1.1.2 Internet Access
Your Zyxel Device provides Internet access by connecting a fiber optic line provided by the Internet
Service Provider (ISP) to the PON port. It supports OMCI (ONU Management and Control Interface) for
provisioning and management by the ISP's OLT (Optical Line Terminal).
1.1.3 Multi-Gigabit
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 only 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
at up to 1 Gbps as speeds of 10 Gbps cannot be attained. Moreover, if network devices with 10 Gbps
network cards are connected to a 10 Gbps Ethernet port, you must use Cat 6 or better Ethernet cables
to achieve 10 Gbps speeds.

1.2 Managing the Zyxel Device
Use the Zyxel Device’s built-in Web Configurator to manage it. You can connect to it using a web
browser. For details on connecting to it, see the Section 2.1.1 on page 12.
1.3 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 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.

1.4.3 UPS Port
You can connect a UPS to the UPS port to keep the Zyxel Device running in case the main power fails.
The following diagram and chart show the pin assignments of the UPS port on the Zyxel Device.
Note: The main power and UPS cannot be used at the same time.
Figure 4 UPS Port Pin Layout
1.4.4 Reset Button
If you forget your password or cannot access the Web Configurator, you will need to use the RESET
button on the rear panel of the device to reload the factory system configuration. This means that you
will lose all configurations that you had previously and the password will be reset to the default.
1Make sure the POWER LED is on (not blinking).
2Press the RESET button for more than 5 seconds or until the POWER LED begins to blink. Wait for the
POWER LED to turn solid green. At this point, the device is reset to factory default settings.

CHAPTER 2
The Web Configurator
2.1 Overview
The Web Configurator HTML-based management interface allows easy system setup and management
through an Internet browser such as Internet Explorer 11, Mozilla Firefox, or Google Chrome. In order to
use the Web Configurator you need to allow:
• Web browser pop-up windows from your Zyxel Device. Web pop-up blocking is enabled by default in
Windows 10.
• JavaScript (enabled by default).
• Java permissions (enabled by default).
2.1.1 Accessing the Web Configurator
1Make sure your Zyxel Device hardware is properly connected (refer to the Quick Start Guide).
2Manually configure your computer’s IP address to 192.168.0.X (X represents any number from 2 to 254.
For example, 192.168.0.25. Then set the subnet mask as 255.255.255.0.
3Launch your web browser. If the Zyxel Device does not automatically redirect you to the login screen,
go to https://192.168.0.1.
4A login screen displays.
5Type the default username admin and the default password from the device label and click Login. If
you have changed the password, enter your password and click Login.

system status, and interfaces.
Figure 10 Connection Status > System Info
Each field is described in the following table.
Table 6 Connection Status > System Info
LABEL DESCRIPTION
Device Information
Model Name This shows the model number of your Zyxel Device.
Serial Number This field displays the serial number of the Zyxel Device.
GPON SN This field displays the serial number the Zyxel Device uses for its GPON connection.
MAC Address This is the MAC (Media Access Control) address unique to your Zyxel Device. The MAC
address uses six pairs of hexadecimal notation and follows an industry standard that ensures
no other adapter has the same address.
Firmware
Version This is the current version of the firmware inside the Zyxel Device.
LAN Information
IP Address This is the current IP address of the Zyxel Device in the LAN.

Chapter 3 System Information
PM7510-R0 User’s Guide

IP Subnet Mask This is the current subnet mask in the LAN.
System Status
System Uptime This field displays how long the Zyxel Device has been running since it last started up. The
Zyxel Device starts up when you plug it in and turn it ON, when you restart it (Maintenance >
Reboot), or when you reset it.
System Resource:
CPU Usage This field displays what percentage of theZyxel Device’s processing ability is currently used.
When this percentage is close to 100%, the Zyxel Device is running at full load, and the
throughput is not going to improve anymore. If you want some applications to have more
throughput, you should turn off other applications.
Memory Usage This field displays what percentage of the Zyxel Device’s memory is currently used. Usually,
this percentage should not increase much. If memory usage does get close to 100%, the
Zyxel Device is probably becoming unstable, and you should restart the device or turn off
the device (unplug the power) for a few seconds.
PON Status
Link State This field displays Up when the interface has a connection with OLT (fiber terminal) and Down
when it does not.
Rx Power This displays the optical transceiver’s optical receiving power in dBm.
Tx Power This displays the optical transceiver’s optical transmitting power in dBm.
Tx Bias This field displays the transceiver’s bias current in mA.
Supply Voltage This field displays the transceiver’s voltage in Volts.
Temperature
(degree C) This field displays the transceiver’s temperature in Celsius.
Interface Status
Interface This field displays the port type.
Status This field displays Up when the GPON connection is up or connected and displays Down
when the connection is down.

CHAPTER 4
LAN
4.1 Overview
A Local Area Network (LAN) is a shared communication system to which many networking devices are
connected. It is usually located in one immediate area such as a building or floor of a building.
4.2 LAN Setup
A LAN IP address is the IP address of a networking device in the LAN. You can use the Zyxel Device's LAN
IP address to access its Web Configurator from the LAN. Click Network Setting to open the LAN screen.
Use this screen to set the Local Area Network IP address, subnet mask, multicast, and IGMP snooping of
your Zyxel Device.
Figure 11 Network Setting > LAN
The following table describes the fields on this screen.
Table 7 Network Setting > LAN
LABEL DESCRIPTION
LAN IP Setup
IP Address Enter the LAN IPv4 address you want to assign to your Zyxel Device in dotted decimal notation,
for example, 192.168.0.1 (factory default).
Subnet Mask Type the subnet mask of your network in dotted decimal notation, for example 255.255.255.0
(factory default). Your Zyxel Device automatically computes the subnet mask based on the IP
address you enter, so do not change this field unless you are instructed to do so.
Multicast Multicast packets are sent to a group of computers on the LAN and are an alternative to unicast
packets (packets sent to one computer) and broadcast packets (packets sent to every
computer).
Devices use the IGMP (Internet Group Management Protocol) network-layer protocol to
establish membership in a multicast group. The Zyxel Device supports IGMP v1/IGMP v2. Select
None to disable it.

IGMP Snooping Select Enabled to enable IGMP snooping to forward group multicast traffic only to ports that are
members of that group. Otherwise, select Disabled.
