Chapter 1 Router Overview
1.1 Introduction
H3C AR 46 Series Routers are next generation high-performance edge routers that
H3C Technology solely developed. They provide high forwarding performance and a
broad service range. The series supports flexible interface cards (FICs), hot swappable
fan modules and power supply units (PSUs) in 1+1 redundancy. Along with the NE
Series Routers, the AR 46 series provides complete network solutions for service
providers and enterprises.
The following are the major features of the AR 46 series.
I. Abundant FIC options
The H3C AR 46 series are available with a wide range of FICs. This allows for great
flexibility and thus protects user investment.
II. Ethernet access
The electrical and fiber (multi-mode and single-mode) Ethernet FICs support PPPoE
and PPPoEoA, and can offer authentication, authorization, and accounting (AAA)
services for Ethernet access. These cards are suitable for providing broadband access,
for example, for government agencies and enterprises.
III. ATM and DSL
Digital subscriber line (DSL) is a simple but highly efficient broadband technology which
achieves great data transmission capacity over existing copper wiring by using the
digital code modulation technology. Installed with an ADSL or G.HSDSL card, the AR 46
series can connect medium-to-small-sized enterprises to digital subscriber line access
multiplexer (DSLAM) equipment across a public switched telephone network (PSTN) to
the Internet.
Asynchronous transfer mode (ATM) transmits, multiplexes, and switches information in
cells. In addition to DSL cards, the AR 46 series is available with these ATM cards: 25
Mbps, 155 Mbps, E3/T3, and IMA-E1/T1. The cards support ATM adaptation layer type
5 (AAL5) and offer traffic services such as constant bit rate (CBR), variable bit rate
(VBR) and unspecified bit rate (UBR). They are well-suited to transfer large packets
and provide high-speed data services. A small to medium-sized enterprise can use
them to connect its network to an ATM network.
IV. MPLS
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
H3C AR 46 Series Routers Installation Manual Chapter 1 Router Overview
1-2
which each router makes forwarding decision. It thus provides faster forwarding speed,
gets support from IP routing and control protocols, and accommodates to emerging
applications. In an MPLS network, labeled packets are transmitted along a label
switched path (LSP) formed by label switching routers. As an LSP is virtually a tunnel
across the public network, MPLS has an intrinsic advantage in terms of VPN
implementation. The AR 46 series usually acts as label edge routers (LERs) to connect
an MPLS domain with a 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
The following are the data security and reliability features that the AR 46 series
supports:
z NAT. Besides some basic functions, NAT can limit concurrent connections to a
single user, and thus alleviate negative impact caused by malicious resources
occupation without affecting the normal network applications. In addition, NAT of
the AR 46 series also provides the application layer gateway (ALG) function
specific to FTP and ICMP.
z Identity authentication protocols such as PAP, CHAP, data RADIUS, VoIP
RADIUS, and TACACS.
z Packet filter and application specific packet filter (ASPF), which fend off external
attacks.
z VPN (including GRE, L2TP, DVPN, and MPLS L2/L3 VPN) and the technologies
of IPSec and IKE. They can ensure security of private networks in an Internet
environment.
z Backup center and virtual router redundancy protocol (VRRP). By providing a
backup scheme in case of communication line or device failures, they enhance
robustness and reliability of networks. Backup center also supports backup load
sharing.
z Hot swappable fans, interface cards, and PSUs to ensure high reliability.
VI. Online software upgrading
You are allowed to upgrade application 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.
H3C AR 46 Series Routers Installation Manual Chapter 1 Router Overview
1-3
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
The AR 46 Series Routers are designed in compliance with 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
The H3C AR 46 series includes AR 46-20, AR 46-40, and AR 46-80. These three
models are similar in chassis structure and layout. All of them use a mid-backplane

1.4.1 RPU
As the core of the router, the RPU functions to process protocols, forward low-speed
packets, govern interfaces, and detect faults. You can gather information about the
operating state of FAN module, PSU, and system by reading their corresponding LEDs
on the main control board; alternatively, you can monitor state using a network
management system. In addition, the main control board provides a hardware reset
button: RESET.

1) 1000 Mbps Ethernet interface
The ERPU provides three 10/100/1000 Mbps Ethernet interfaces that each
accommodate an RJ-45 connector and a small form-factor pluggable (SFP) module
respectively for electrical and optical connections. But you can use only one connection
at a time.
Five types of 1000Base-FX SFP transceiver modules are available: multi-mode
short-haul (850 nm), single mode medium-haul (1310 nm), single mode long-haul
(1310 nm), single mode long-haul (1550 nm), and single mode ultra-long haul (1550
nm). They all provide LC interfaces and are hot swappable.

2) Compact Flash (CF) slot
The ERPU provides one CF (PCMCIA) slot for a hot swappable CF card.
A CF card can store application programs, configuration files, and log information. With
it, you can conveniently perform such operations as online upgrade and log
management.
