Chapter 1
Satellite router overview
The HX90 satellite router connects to a satellite network to provide Internet or
intranet service or both to a host—typically a computer—or to multiple hosts on a
wired (Ethernet) or wireless local area network (LAN). The router has two Ethernet
LAN ports so it can be connected to one or two LAN subnets. The HX90 satellite
router is designed to meet the needs of enterprise business customers, small
business users, and consumers.
The HX90 is an Internet Protocol (IP) router, and so it eliminates the need for an
external router.
Figure 1: HX90 satellite router

Chapter 1 • Satellite router overview
12 1039457-0001 Revision A
After your HX90 satellite router has been installed, you can use a web browser on
your computer to access the Internet or an intranet. You can use a LAN to extend
Internet or intranet connectivity to multiple computers.
The satellite router has a System Control Center that provides access to system
information such as the router’s operating status and troubleshooting information.
The System Control Center is described in Chapter 2 – System Control Center on
page 17.
Terminology
In this user guide:
•Satellite router and router both refer to the HX90 satellite router.
•Acronyms are identified in Appendix C – Acronyms used in this guide, on page 89
Scope of this user guide
This user guide describes the features and operation of the HX90 satellite router,
which provides you Internet access by satellite. This guide also provides certain
reference information, such as the meaning of the router’s front panel LEDs. The
HX90 satellite router is designed to meet the needs of enterprise business customers,
small business users, and consumers.
Audience
This guide is intended for users of the HX90 satellite router.
The satellite router’s role
Figure 2 illustrates how the HX90 satellite router provides connectivity and

This illustration shows the HX90 with a single computer host. However, the satellite
router may also be used in a multiple-host configuration, in which hosts on a LAN
share satellite Internet or intranet connectivity through an Ethernet hub, router, or
wireless base station. A host may be a computer using Windows, Mac OS, or another
supported operating system.
Note: You must provide and configure hub, router, or wireless base station
equipment if any of these are used.
Even though the HX90 satellite router is typically connected to a host, it is
self-hosted, meaning it can operate without a host. It does not depend on a
computer to establish and maintain the Internet or intranet connection. However,
the router must be connected to a satellite antenna.
The Hughes Internet Gateway is a Hughes-operated satellite station that provides a
connection between the Internet and the satellite. The gateway routes data to and
from the Internet and to and from the satellite. The satellite transmits a signal to the
antenna, which is passed to the satellite router to provide Internet connectivity.
This message applies if you use the HX90 satellite router in the United States: If
servicing of the satellite router’s outdoor antenna assembly is necessary, the
FCC requires that the work must be done by a trained professional because the
antenna assembly transmits RF energy.
