Chapter 1 Product Overview

1.1 Brief Introduction

H3C SecPath V1000-A Security Gateway (referred to as the security gateway

throughout the manual) is new-generation network security device intended for the use

on enterprise networks. It can act as the core security gateway for small-and

medium-sized enterprises or the convergence and network access gateway for large

enterprises.

H3C SecPath V1000-A Security Gateway (the SecPath V1000-A) provides:

z Two fixed 10/100/1000 Mbps auto-sensing Ethernet interfaces that can be optical

or electrical

z One multifunctional interface module (MIM) extended slot, which can hold

1FE/2FE/1GBE/2GBE

z Dual-power redundancy (AC+AC)

z Temperature sensing inside the chassis

z Network management

With the support to hot-swappable modules, power redundancy and temperature

monitor, the SecPath V1000-A can deliver carrier-level reliability.

The security gateway supports multiple Virtual Private Network (VPN) services, such

as Layer 2 Tunneling Protocol (L2TP) VPN, IP Security (IPsec) VPN, Generic Routing

Encapsulation (GRE) VPN, and Dynamic VPN. It can connect to remote users through

dial-up, leased line, VLAN or tunnel, thus building VPNs in the form of internet, intranet,

or access network. The security gateway brings together the technologies of firewall,

AAA, Network Address Translation (NAT), and Quality of Service (QoS) to provide a

safe and reliable private network over the insecure Internet.

The SecPath V1000-A has the following features:

I. IP VPN solution

Networks benefit enterprises in many ways; one of them is that a company

headquarters can release important information to its branch offices quickly and

conveniently. To interconnect the networks of a company over the Internet, however,

you need VPN technologies. The SecPath V1000-A provides abundant IP VPN

services; among them, L2TP and GRE provide layer 2 and layer 3 tunnels, and IPsec

provides tunnels encapsulated with a security protocol to have a securer network.

The SecPath V1000-A has powerful tunneling capabilities, supporting up to 10000

connections in parallel and with an encryption speed of 250 Mbps.

II. Data security and reliability

The security gateway supports:

z NAT. Besides the basic functions, the NAT of the SecPath V1000-A can limit the

number of concurrent connections to a single user. This eliminates the malicious

resource seizures while common network applications are being provided. In

addition, its enhanced NAT ALG function provides NAT traversal for H.323, FTP,

ICMP, and so on.

z AAA and RADIUS user authentication protocols.

z Packet filter and Application Specific Packet Filter (ASPF) to prevent the attacks

from external networks.

z VPN (including GRE and L2TP) with the IPsec and IKE technologies to guarantee

the security of private networks over the Internet.

z Virtual Router Redundancy Protocol (VRRP) to provide backup in case of

communication line or equipment failures. This effectively enhances network

robustness and reliability.

z Deeper application recognition (DAR) to recognize and classify packets more

deeply, thus enhancing the control over data flows.

z Object oriented management, simplifying configuration management and

improving the usability.

III. Online software upgrade

You can upgrade the application and Boot ROM programs on line to add features and

extend functions.

IV. Network management

The security gateway supports the SNMPV3 network management and provides

powerful device management.

V. Regulatory compliance

Designed taking into considerations the national and international standards dominant

in China, North America, Europe, Australia, and Japan, the security gateway complies

with the requirements of these countries and regions in EMC, safety, and network

access.

Installation Manual

H3C SecPath V1000-A Security Gateway Chapter 2 Preparation for Installation

2-1

Chapter 2 Preparation for Installation

2.1 Site Requirements

The security gateway must be used indoors. To guarantee the normal operation and

long service life of your security gateway, install it in an environment that can meet the

requirements in the following subsections.

2.1.1 Temperature/Humidity

The equipment room must maintain adequate temperature and humidity. Long-lasting

high humidity is prone to cause bad insulation and even electricity creepage.

Sometimes the mechanical performance changes of materials, the rustiness and

corrosion of some metal parts are also likely to occur. If the relative humidity is too low,

the captive screws can become loose due to insulation washer contraction. Meanwhile,

the static is likely produced in the dry environments, jeopardizing the CMOS circuit of

the product. The higher the temperature is, the greater the damage to your device.

Long-lasting high temperature can speed up the aging of the insulation materials,

greatly lower the device reliability, and hence significantly shorten its service life.

The following table lists the temperature and humidity requirements.

Table 2-1 Temperature/Humidity requirements in the equipment room

Temperature Relative humidity

0 – 40

C (32 – 104

F) 10 – 90% (non-condensing)

2.1.2 Cleanness

Dust is a hazard to the operating safety of your device. The dust accumulated on the

chassis can cause electrostatic adsorption, one of the sources that cause the poor

contact of connectors or metal contact points. This not only shortens the service life of

your device but also causes communications failures. When the indoor relative

humidity is low, electrostatic adsorption is more likely to happen.

The equipment room must be free of explosion hazards and the electrical and magnetic

conductible dust as well. The contents of the dust must be limited as shown in the

following table:

Installation Manual

H3C SecPath V1000-A Security Gateway Chapter 2 Preparation for Installation

2-2

Table 2-2 Limit to the content of dust in an equipment room

Substance Unit Content

Dust Particles/m³

≤ 3 X 104

(No visible dust on the

table top for three days)

Note: diameter of a dust particle ≥ 5μm

Besides the dust, there are rigorous limits on the harmful gases that can accelerate the

erosion and aging of metals, such as salts, acids, and sulfides, as shown in the

following table.

Table 2-3 Limits on the contents of harmful gases in the equipment room

Gas Maximum (mg/m

)

SO2 0.2

H2S 0.006

NH3 0.05

Cl2 0.01

2.1.3 ESD Prevention

Although the security gateway is designed to be electrostatic discharge (ESD)

preventive, the card circuits and even the device can be badly damaged when

excessive static electricity is present.

On the communication network connected to your device, the static electricity mainly

comes from the outside electrical fields, such as outdoor high-voltage power cables

and lightning, and from the indoor environments, floor materials and the internal system

such as the equipment frame. To prevent damage, observe the following:

z Connect your device and the floor to the earth ground properly.

z Keep the equipment room as clean as possible.

z Maintain adequate temperature and humidity.

z Wear an ESD-preventive wrist strap and clothes when handling the circuit board.

z Place the removed circuit board upward on the ESD-preventive workbench, or into

a static shielding bag.

z Hold the circuit board by its edge when observing or moving it, avoiding direct

contact with the elements on it.

2.1.4 Electromagnetic Environment

All interference sources, wherever they are from, impact the security gateway

negatively in the conducted emission patterns of capacitance coupling, inductance

coupling, electromagnetic wave radiation, and common impedance (including the

grounding system) coupling. To resist the interference, make sure to:

z Take effective measures against the interference caused by the power supply

grid.

z Use an earthing system or lightning protection grounding different from that for the

power supply equipment and keep them as far as possible.

z Keep the device far from strong the power radio launchers, radar launchers, and

high frequency and high-current equipment.

z Use electromagnetic shielding when necessary.

2.1.5 Lightning Protection

Although the security gateway is designed to be lightning resistant, your device can get

damaged when excessive lightning is present. To protect your device against lightning,

z Ensure the chassis is connected to the earth ground.

z Ensure the earth point of the power socket is well connected to the earth ground.

z Add a lightning arrester onto the front end of the power input to better protect the

power supply from lightning strikes.

2.1.6 Mounting Rack

When installing the device in a rack, make sure that:

z There is adequate clearance between the air inlet/exhaust vents and the rack for

ventilation.

z The rack has a good ventilation system.

z The rack is firm enough to support the device and its accessories.

z The rack is well earthed.

2.2 Safety Precautions

Be sure that you observe all safety precautions when you install your security gateway

and pay adequate attention to the following icons:

Warning appears in operation procedures that, if performed incorrectly, might

cause bodily injury to the operators or damage the device.

Caution means care should be taken in these operations during installation and

use. Improper operations may result in abnormal running of the device.
