CHAPTER 1
Introduction
1.1 Overview
This chapter introduces the main features and applications of the NBG7815, also called ARMOR G5. It
has four 1 Gbps Ethernet LAN ports, one 10G multi-gigabit LAN port, and one 2.5G/1G WAN port.
The NBG7815 extends the range of your existing wired network without additional wiring, providing easy
network access to mobile users. You can set up a wireless network with other IEEE 802.11a/b/g/n/ac
compatible devices. The NBG7815 is able to function both 2.4GHz and 5GHz networks at the same time.
A range of services such as a firewall and content filtering are also available for secure Internet
computing.
There is an USB port on the side panel of your NBG7815. You can connect an USB memory stick, an USB
hard drive, or an USB device for file sharing. The NBG7815 automatically detects the USB device.
1.1.1 Multi-Gigabit
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 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 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 6A or better Ethernet cables
to achieve 10 Gbps speeds. Most buildings, at the time of writing, use Cat 5e or Cat 6 Ethernet cables.
2.5 Gbps Multi-Gigabit (IEEE 802.3bz) Ethernet ports on the NBG7815 automatically allow connections
up to the speed of the connected network device (100 Mbps, 1 Gbps, 2.5 Gbps), and you just need to
use a Cat 5e or Cat 6 Ethernet cable.
1.2 Applications
Your can have the following networks with the NBG7815:
• Wired. You can connect network devices via the Ethernet ports of the NBG7815 so that they can
communicate with each other and access the Internet.
