This document describes the hardware, functions, installation, configuration, operation and
maintenance (OM) of the eA660 series customer premises equipment (CPE).
HUAWEI eA660 is a piece of customer premises equipment (CPE) that functions as the long
term evolution (LTE) wireless gateway. It implements the conversion between LTE wireless
data and wired Ethernet data and supports data backhaul. The eA660 series can be used
independently and deployed outdoors.
The eA660 supports the LTE R8 standards and provides the following services:
Data services
The eA660 series uses LTE broadband technologies to support high-speed broadband
network access, data backhaul, and video surveillance.
Small-scale local area network (LAN)
The eA660 series can connect to external concentrators and Ethernet switches or routers
to set up a LAN with multiple computers. When terminal devices on the LAN connect to
the eA660 using network cables, the terminal devices can provide data services.
Security services
The eA660 series supports the firewall and PIN password, which protects your
computers when you access the Internet.
Firewall services
The eA660 series supports the following firewall services:
−
Firewall enabling or disabling: enables or disables firewalls.
−
Media access control (MAC) address filtering: prevents certain MAC addresses from
accessing the computers on a LAN.
−
IP address filtering: blocks certain IP addresses from accessing the local computers.
−
URL filtering: prevents computers from accessing certain URLs.
Local and remote management and maintenance
The eA660 series can be locally configured in the local city to implement device
management and network configuration, thereby ensuring stable operation of the device.
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) This device may not cause harmful interference, and (2)
this device must accept any interference received, including interference that may cause
undesired operation.
FCC Caution To assure continued compliance, any changes or modifications not
expressly approved by the party responsible for compliance could void the user's
authority to operate this equipment.
FCC Radiation Exposure Statement To comply with FCC RF exposure requirements in
section 1.1307, a minimum separation distance of 20cm is required between the antenna
and all public persons.
1.2 Application Scenarios
The eA660 provides wireless broadband and wired Ethernet data services.
The eA660 is deployed outdoors and provides wireless gateway services. The eA660 can be
deployed independently or used in conjunction with the eA100, which is deployed indoors
and connected to the eA660 using a network cable, enabling the eA660 to provide Wi-Fi and
other Internet services.
For details about the eA100, see the eLTE2.1 eA100 Series CPE Product Description.
Figure 1-1 shows an application scenario in which the eA660 is used with the eA100.
The eA660 provides a variety of data services, such as LTE-TDD wireless routing and
converting LTE wireless data into wired Ethernet data, and vice versa. Figure 1-2 shows an
application scenario in which the eA660 is used in private industrial networks.
Figure 1-2 The eA660 deployed in industrial private networks
The following example describes how to use the eA660 for video monitoring.
1. Use a power adapter to supply power for the eA660 or video camera, as shown in Figure
1-3.
Figure 1-3 The eA660 connected to a video camera.
2. Use a network cable to connect the eA660 to an external device. If the eA660 connects
to a single device, connect the power adapter directly to the eA660. If the eA660
connects to multiple devices, connect the power adapter to a Hub or switch and then to
the eA660, as shown in Figure 1-4.
The eA660 is successfully registered
to the network.
The product fails to register to the
network.

2.2.1 PoE Network Cable
The power over ethernet (PoE) network cable is a shielded network cable that is used to
connect the PoE port of the eA660. The PoE network cable connects to an RJ45 connector at
both ends.
Background Information
The PoE network cable transmits data signals to the eA660 and provides DC power for the
equipment.
Off
Controlled by the
hardware temperature.
The signal strength is equal to or
smaller than –120 dBm.
When the hardware temperature is
lower than 0°C, the hardware is heated
and the indicator is on.
When the hardware temperature is
higher than 0°C, the indicator is off.
