Chapter 1 Router Overview
1.1 Introduction
Quidway AR 46 Series Routers are next generation high-performance edge routers
that are developed by Huawei Technologies Co., Ltd (hereinafter referred to as Huawei
Technologies). Compared with the traditional Low-and-Mid-Range Routers of Huawei
Technologies, they allow of higher forwarding performance and a broader service
range. Quidway AR 46 Series Routers offer a more perfect hardware design,
supporting Flexible Interface Cards (FICs), hot swappable Power Supply Unit (PSU),
and 1+1 power backup. Along with NE Series Routers, AR 46 Series can provide a
complete solution for service providers and enterprise networking.
Following are the main features of AR 46 Series Routers.
I. Abundant FIC options
Tens of FICs are available for Quidway AR 46 Series Routers. Therefore, the user is
allowed of great flexibility in card selection and can save the network investment by
selecting the needed FICs in a proper quantity.
II. Provision of Ethernet access solution
The electrical and fiber (multi-mode and single-mode) FE FICs available for the Router
support PPPoE and PPPoEoA that can offer the Authentication, Authorization, and
Accounting (AAA) services for Ethernet access, hence satisfying the requirements of
government offices and enterprises in broadband access.
III. Provision of ATM and DSL solution
Digital Subscriber Line (DSL) is a simple but highly efficient broadband technology that
achieves great data transmission capacity over the existing copper wiring by using the
digital code modulation technology. The ADSL and G.HSDSL cards available for AR 46
Series Routers allow the medium-to-small-sized enterprises to access the Digital
Subscriber Line Access Multiplexer (DSLAM) equipment via Public Switched
Telephone Network (PSTN) and then the Internet.
Asynchronous Transfer Mode (ATM) transmits, multiplexes, and switches information
in cells. AR 46 Series Routers provide 25Mbps, 155Mbps, E3, and T3 ATM cards,
supporting ATM Adaption Layer Type 5 (AAL5) and offering the traffic services like
Constant Bit Rate (CBR), Variable Bit Rate (VBR) and Unspecified Bit Rate (UBR).
Installation Manual
Quidway AR 46 Series Routers Chapter 1 Router Overview
1-2
Hence, such routers are well-suited to the high-speed data service and the
transmission of large packets, hence implementing the interconnection between the
medium-and-small-sized enterprise networks and the ATM networks.
IV. Provision of MPLS solution
Multiprotocol Label Switching (MPLS), a combination of IP and ATM technologies,
replaces the IP header with a short and length-fixed label as traffic identifier, based on
which each router makes the forwarding decision. Thus, it provides faster forwarding
speed, gets support from IP routed protocols and control protocols, and hence meet the
requirements that various new applications put on the network. MPLS VPN is a VPN
technology that implements the interconnection of private networks via Label Switched
Paths (LSPs). As LSP is a tunnel across the public network on its own, MPLS has an
intrinsic advantage in terms of VPN implementation. AR 46 Series Routers usually act
as Label Edge Routers (LERs) to connect an MPLS domain with non-MPLS domain or
connect MPLS domains of different service providers, implementing service
classification, label distribution, encapsulation, and multi-label peel-off.
V. Data security and reliability
z Support NAT. Besides some basic functions, the NAT available for AR 46 can limit
concurrent connections to a single user, and thus alleviate the negative impact
caused by malicious resources occupation without compromising the normal
network applications. NAT of AR 46 also provides the ALG (Application Layer
Gateway) function to FTP and ICMP.
z Support the authentication protocols such as PAP, CHAP, data RADIUS, and
VoIP RADIUS.
z Implement packet filter and firewall for preventing the intrusion from an external
networks.
z Support VPN (including GRE, L2TP, and MPLS) and provide IPSec, and IKE,
hence ensuring the security of the private networks in an Internet environment.
z Support the Backup Center and Virtual Router Redundancy Protocol (VRRP)
technologies, enhancing the robustness and reliability of the network by providing
a backup scheme in case of communication line or device failures. So far, backup
center supports backup load sharing.
z Support hot swap of fans, interface cards, and power module to ensure high
reliability.
VI. Online software upgrading
You are allowed to upgrade the application programs and Boot ROM programs, and
add new features and functions on line as needed.

VII. Abundant fault isolation methods
z You are available with the means to monitor the states of system configurations,
system service channels, and system resources, as well as fault indication via
console and network management host. In addition, logging function is provided
for recording and outputting the abnormal information.
z You are allowed to monitor the FIC running state and make the judgment by
observing the LEDs on FIC panels.
z You are also provided with the functions of in-service system test, out-of-service
system test. In addition, loopback test and hardware key module self-test are
allowed.
VIII. Regulatory compliance
AR 46 Series Routers are designed taking into full consideration the regulations and
standards of China, North America, Europe, Europe, Australia, and Japan in EMC,
safety, network access, and some other aspects.
1.2 Router Model and Structure
Quidway AR 46 Series Routers include Quidway AR 46-20, 46-40, and 46-80. These

1.4.1 RPU
I. Functions
As the core of routers, RPU functions primarily to process protocols, forward low-speed
packets, control interfaces, and detect faults. The state monitoring information, such as
the operation states of FAN, PWR, and system can be shown directly via the LEDs on
the RPU, or reported to the Daemon for the monitoring on the network management
system. In addition, RPU also provides the hardware reset button RESET.
Following are the functions of RPU.

1.4.2 PWR
I. Functions
The power supply system of Quidway AR 46 Series Routers can work in either
single-power or dual-power mode. In dual-power mode, the two PWRs (either
supplying DC or AC power) function in a redundant way (that is, loading sharing mode).
The input interruption or failure of a PWR will not affect the operation of another PWR,
and this operating PWR will provide all the power required by the system.
Quidway AR 46 Series Routers provide two types of PWRs, i.e., AC PWR and DC
PWR, both providing the output power of 350W. PWR has the functions of overcurrent
protection and overvoltage protection.
You can connect the PWR to the backplane by inserting it from the rear of router
chassis. It is hot swappable and its switchover will not affect the ongoing system
operation.
Note:
If you want to install an AR 46 Series Router in a communication equipment room, you should make sure
that the power distribution cabinet can provide the lightning protection box or arrester against the current of
20KA and above.

LED Description
ALM (red)
PWR failure LED. ON means PWR is not in place or has failed.
RUN (green)
PWR operation LED. Constant ON means PWR is operating normally, and OFF
means PWR has failed.
AC/DC OK (red)
PWR input LED (only for AC PWR). Constant ON means the normal voltage (85 ~
264V) is inputting, and OFF means the voltage input is not normal.
1.4.3 FAN
I. Functions
AR 46-20 and AR 46-40 are configured with six fans that are separated into three
groups, and AR 46-80 is configured with eight fans that are separated into four groups.
The two fans in a group are working in a redundant way. When all these fans are
working normally, the operating temperature of the system can be maintained in the
range of 0 to 55oC. As the failure of a fan will not affect the operation of other fans, the
system will still be able to operate in the normal temperature. The rotating speed of the
fans is controlled by the RPU and is in the range of 50% to 100%. The FAN controller
uses two parameters, i.e., low-temperature threshold and high-temperature threshold
to control the rotation speed of the fans, with the former corresponding to 100% rotating
speed and the latter corresponding to 50% rotating speed. The system will send out
rotation stop alarm signals in case any fan fails. The alarm and state LEDs of FAN are
located on the RPU front panel.
