Chapter 1 Product Overview
1.1 Introduction
H3C AR 18-2X Series Routers (hereinafter referred to as the AR
18-2X series) are Ethernet access routers designed for small office
home office (SOHO) subscribers. By far, the series have six models:
AR 18-21/18-22/18-22-8/18-22S-8/18-23-1/18-23S-1. They provide
an uplink Ethernet interface and four downlink layer 2 (L2) switched
10/100BASE-T Ethernet interfaces that can be isolated.
The AR 18-2X series support multiple virtual private network
(VPN) services, such as layer 2 tunneling protocol (L2TP) VPN, IP
security (IPSec) VPN, generic routing encap sulatio n (G RE) VPN, and
dynamic VPN (DVPN). They can provide tunnel connections to remote
users to build VPNs that can be internets, intranets, or access
networks.
The series support firewall, AAA (authentication, authorization,
accounting), network address translation (NAT), and quality of service
(QoS). Therefore, they can ensure security and guaranteed services
to the private networks constructed on the open Internet.
In the series the AR 18-22S-8 and AR 18-23S-1 has a build-in
hardware encryption chip, which can significantly improve encryption
performance.
The interfaces that the AR 18-2X series provide are compliant
with the international standards and can work with the products of
other vendors at every layer. The existing investment of users can
thus be protected to the maximum.

2.6 Connecting the Router to LAN
I. Ethernet cable
A 10/100Base-TX Ethernet interface is usually connected to an
Ethernet using a category 5 twisted pair cable, as shown in
Figure 2-5:
Figure 2-5 Ethernet cable assembly
Ethernet cables fit into two categories: straight-through and
crossover.
z Straight-through cable, at both ends of which, the wires are
crimped in the RJ45 connectors in the same sequen ce. The
cable is used for connecting different types of devices, such
as a terminal device (PC for example) or router to a Hub or
LAN switch.
z Crossover cable, at both ends of which, the wires are
crimped in the RJ 45 connectors in different sequence. The

cable is used for connecting the same type of devices, such
as PC to PC or PC to router.
Caution:
In preparing network cables, shielded cables are preferred for the
sake of electromagnetic compatibility.
II. Connecting an Ethernet cable
Caution:
Read the mark above the port to be connected ca refully before making
connection to make sure it is the right port.
The 10/100BASE-T interface on the AR18-2X series supports
MDI/MDIX autosensing. Therefore, you can connect your router to
another device using either straight-through cable or crossover cable
without considering whether the two devices are of the same type.
You can simply connect one end of the network cable to the
Ethernet port on the router and the other end to another device.
2.7 Verifying Installation
After you complete installation, verify that:

M+B (that is, both of type M and B) file exists, it is impossible
to have another M or B file. If you change the file type of
another file to B, the M+B file becomes a type M file.
z You can modify the file name of an application image in
Flash memory using the command after it boots. For more
information, refer to Comware V3 Operation Manual –
System Management.
z You cannot modify the file type of the type S application
image file, but you can modify the file type of type M or B and
N/A application image files in the Boot Rom menu or using
commands after the application image boots.
z Secure boot file is the last system boot resort. You can
download it in the Boot Rom menu and must name it
secure.bin. However, you cannot modify this file or change
the type of another file to S. If you change the name of the
secure boot file with the rename command after the system
boots, the file is removed from Flash memory. To use the
secure boot file after that, you need to download it again.
