Configuring USB Modems
This document describes how to configure USB modems for use with Embedded NGX 7.5 appliances.
Note: The Embedded NGX screenshots that appear in this document relate to
Safe@Office gateways. However, the procedure is relevant for all of the Embedded
NGX appliances listed in “Prerequisites,” page 2.
Overview
The Embedded NGX 7.5 appliance allows attaching a wide variety of USB-based dialup (PSTN/ISDN)
and cellular (2G/3G) modems to its USB 2.0 ports. An attached USB modem can serve as a backup
Internet connection. Alternatively, in locations where broadband Internet access is not widely available,
in POS (Point of Sale) applications, and in mobile applications, the USB modem can serve as the
primary Internet connection. The modem can be permanently connected (always on), or it can be
automatically dialed when needed and disconnected when not in use (dial on demand).
Note: The Embedded NGX appliance supports attaching one USB modem.
2 Configuring USB Modems
Prerequisites
In order to use a USB modem with your Embedded NGX appliance, you will need the following:
An Embedded NGX appliance with USB ports
These include: Safe@Office 500W, Safe@Office 500W ADSL, Safe@Office 425W/425WU,
UTM-1 Edge X ADSL, UTM-1 Edge W, UTM-1 Edge W ADSL, or UTM-1 Edge X Industrial.

You can buy a compatible USB modem directly from your local retailer, or you can order one from
Check Point. For information on pricing and availability, please contact your Check Point

Connecting USB Modems
Warning: Before attaching a USB modem, ensure that the total power drawn by all
connected USB devices does not exceed 2.5W per port (0.5A at 5V). If the total current
consumed by a port exceeds 0.5A, a powered USB hub must be used, to avoid damage
to the gateway. For information on the current used by your USB modem, refer to the
modem's specifications.
