his chapter provides information on the EN-4000™ chassis hardware and
specifications.
The EN-4000 complies with the European Union's directive on restriction of hazardous
substances (ROHS). This directive places strict controls on pollutants, including the
elimination of lead in the manufacturing process.
Highlights of the EN-4000 include:
• Industrial-hardened cybersecurity appliance and router
• IP security (IPsec) VPNs with DES, 3DES, and AES (256-bit), to maintain private
transmissions over a public network
• SSL/TLS encrypted link to the wide-area network (WAN)
• Connectivity over any IP/MPLS, Frame Relay, circuit-switched, or cellular wireless
network
• Choice of WAN interface via cellular data, T1/E1 CSU, serial, or Ethernet, optical
fiber, modem
• Cellular, Wi-Fi, and Bluetooth connectivity
• Up to four serial ports for legacy traffic support
• Alarm ports (dry contact sensing, voltage sensing, dry contact closure outputs)
• Legacy protocol support via serial or IP conversion/interworking

wired optical fiber, and cellular uplinks, complete remote management, and
support for current and legacy data protocols.
The EN-4000 chassis is designed to operate in industrial environments with a
wide range of ambient temperatures. Its tight all-metal enclosure resists dust,
moisture, and electromagnetic interference (EMI).
The EN-4000 has expanded memory and a high-speed processor that allow it to
handle multiple ports and high-speed network connections while converting
protocols, routing packets, and applying firewall rules and other security
measures.
One internal module for Wi-Fi and Bluetooth communications and one internal
cellular wireless module is are standard on selected models. Because the modules
are internal, they leave the chassis’s expansion slots open for other modules.Up
to four antennas handle 3G/4G/LTE cellular, advanced Wi-Fi, and services.
There is no cooling fan or other moving parts. All models are built on the same
hardware platform. Expansion slots for optional modules enhance flexibility and
let the EN-4000 router adapt to specific user needs. You can add Ethernet ports,
a modem, wireless ports, encryption hardware, a digital signal processor (DSP),
serial ports, T1/E1 CSU interfaces, and fiber-optic links.
Slots allow installation of serial data ports, a modem behind an FXS analog
telephone interface, and up to five additional Ethernet ports. An internal switch
allows any port to handle upstream connections and locally attached equipment.
You can select a model that uses a fixed configuration of a cellular wireless port
and one Ethernet port. Another model contains three expansion slots—two in the
front and one internal—for optional hardware modules.
Technicians with modest skills, using only a screwdriver, can install and change
most modules in the field.
The EN-4000 requires minimal power. Typical configurations draw less than
13 watts. The power source options are:
• A 12V–48V DC input line, at several voltages
• An AC power supply unit, supplying 5 V DC to the chassis
A DC power input can form a redundant pair with an AC power input: One is the
chassis’s primary input power source, and the other source provides power if the
primary source is down.

RJ45 Serial Port
Figure 1-3 shows the dual serial-port module for the EN-4000. The module is
installed in one of the expansion slots on the front of the chassis. (The module
can be installed in either expansion slot.)
As the name indicates, this module provides two serial ports. The serial ports use
RJ45 connections.

Green
Each group of 4 LEDs indicates the status of a
connection to a cellular wireless network and the
strength of signals from that network:
• Number of lights
• The number of signal-strength LEDs that light up (1 to
4 lights) indicates the strength of the signal from the
cellular wireless carrier.
• Steady
• 1 to 4 steady (unblinking) LEDs indicate that the port
is connected to a cellular wireless network.
• Blinking
• 1 to 4 blinking LEDs indicate one or both of the
following:
- that a cellular wireless network is available but that
the port does not have an IP address.
- that the cellular wireless module has not been
activated on the cellular wireless network.
(In either case, configure an IP address for the port,
so that the port can connect to the network. See the
document Configuring General Settings for the
EN-4000.)
