3Com Router 3000 Ethernet Family Installation Guide

Chapter 1 Product Overview

1. Product Overview

1.1 Introduction

3Com Router 3000 Ethernet Family are Ethernet access routers designed for small office home office (SOHO) subscribers. They provide an uplink Ethernet interface and four downlink layer 2 (L2) switched 10/100BASE-T Ethernet interfaces that can be isolated.

The 3Com Router 3000 Ethernet Family support multiple virtual private network (VPN) services, such as layer 2 tunneling protocol (L2TP) VPN, IP security (IPSec) VPN, generic routing encapsulation (GRE) VPN, and Huawei dynamic VPN (DVPN). The y 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 (NA T), 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 3Com Router 3000 Ethernet Family has a build-in hardware encryption chip, which can significantly improve encryption performance.

The interfaces that the 3Com Router 3000 Ethernet Family series provide are compliant with the international standards and can work with the produ cts of other vendors at every layer. The existing investment of users can thus be protected to the maximum.

2. Installing the Route

2.1 Safety Precautions

Caution:

Observe the safety precautions in this section when installing or maintaining your router to avoid bodily injuries or device impairment caused by improper actions.

z Maintain an indoor temperature in the range 0 to 45 C (32 to 113 F) and a humidity level

in the range 10 to 90%.

z Keep the router away from radio transmitting stations, radar stations, and high-frequency

devices. Use electromagnetic shielding if necessary.

z Do not put the router on an unstable table or platform. z Make sure that the rack/workbench has a good ventilation system and is properly

grounded.

z Wear an ESD-preventive wrist strap during installation, making sure that it has good

skin-contact.

z Reserve adequate clearance at the air intake and exhaust vents for ventilation. z For power supply, use a single-phase three-line power socket with a neutral point or use

a universal PC power socket, making sure that the neutral point is well connected to building ground.

z Make sure the correct voltage is used. z Put a lightning arrester at the front end of the power input to enhance its lightning

protection. To this end, put a special lightning arrester at the front end of signal cables that are led outdoors, such as ISDN, telephone, and T1 cables.

z Do not open the chassis when the router is operating or when electricity hazards are

present to avoid electrical shocks. Before you open the chassis, obtain the permission of your sales agent.

z Correctly connect the interface cables. Do not connect a telephone cable (including the

ISDN cable) to a serial port.

z Do not hot swap any cable.
