3Com Router 6000 Family Installation Manual

Preparing for Installation

Chapter 1 Router Overview

1.1 Introduction

3Com 6000 Routers are next generation high-performance edge routers that 3Com

Corporation solely developed. They provide high forwarding performance and a broad service

range. The Router 6000 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 Router 6000 provides complete network solutions for service providers and enterprises.

The following are the major features of the Router 6000.

I. Abundant FIC options

Abundant FICs are available with the Router 6000 allowing great flexibility and investment protection.

Chapter 1

II. Ethernet access

The electrical and fiber (multi-mode and single-mode) FE FICs available with the Router

6000 support PPPoE and PPPoEoA that can offer authentication, authorization, and

accounting (AAA) services for Ethernet access, hence satisfying the requirements of government offices and enterprises in broadband access.

III. ATM and DSL

Digital subscriber line (DSL) is a simple but highly efficient broadband technology that

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 Router 6000

can connect the medium-to-small-sized enterprises to the digital subscriber line access

multiplexer (DSLAM) equipment through a public switched telephone network (PSTN) and then to the Internet.

Asynchronous transfer mode (ATM) transmits, multiplexes, and switches information in

cells. The Router 6000 can be installed with these ATM cards: 25 Mbps, 155 Mbps, E3,

and T3. The cards support ATM adaption 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

medium-and-small-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 each routers

3Com Corporation

1-2

3Com Router 6000 Family Installation Manual

forwarding decision. It thus provides faster forwarding speed, gets support from IP routed

protocols and control protocols, and accommodates to emerging applications. MPLS VPN

is a VPN technology that uses label switched paths (LSPs) to interconnect private

networks. As a LSP is virtually a tunnel across the public network, MPLS has an intrinsic

advantage in terms of VPN implementation. The 3Com 6000 Routers usually act 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 Router 6000 supports:

z NAT. Besides some basic functions, NAT can limit concurrent connections to a

single user, and thus alleviate negative impacts caused by malicious resource

occupation without affecting the normal network applications. In addition, NAT of

the Router 6000 also provides the application layer gateway (ALG) function specific to FTP and ICMP.

z Authentication protocols such as PAP, CHAP, data RADIUS, and VoIP RADIUS. z Packet filter and firewall, which fend off external attacks.

z VPN (including GRE, L2TP, and MPLS) 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.

Chapter 1

Preparing for Installation

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 The monitoring of the states of system configurations, system service channels,

and system resources is available, 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 and

out-of-service system test. In addition, loopback test and hardware key module self-test are allowed.

1.4.2 PSU

I. Functions

The power supply system of the Router 6000 can work in either single-power or dual-power

mode. In dual-power mode, the two PSUs (DC-input or AC-input) function in redundancy or

load sharing mode. That means, when a PSU fails or its power supply is disconnected, another PSU can still work and supply all the power required by the system.

Both AC-input PSU and DC-input PSU are available with the Router 6000. The PSUs supply 350W power and provide overcurrent and overvoltage protection.

You can connect a PSU to the backplane by inserting it from the rear of the router chassis. It is hot swappable and its switchover does not affect the ongoing system operation.

 Note:

Chapter 1

When installing your router in a communications equipment room, ensure that the AC

power distribution cabinet can provide a lightning protection box or arrester against

the current of 20 KA and above.

Chapter 2 Preparing for Installation

2.1 General Site Requirements

The Router 6000 must be used indoors. To guarantee normal operation and longevity of your device, its installation site should meet the requirements described in this chapter.

2.1.1 Temperature and Humidity

The equipment room must maintain proper humidity to prevent poor insulation, electricity

creepage and corrosion accompanying high humidity, or washer contraction and

electrostatic discharge accompanying low humidity. In dry environments where the relative

humidity is very low, electrostatic discharge (ESD) is more likely causing the complementary metal-oxide-semiconductor (CMOS) circuitry to fail.

A proper temperature condition must also be maintained to prevent premature material aging and degraded reliability accompanying high temperature conditions.

Chapter 2

The following table lists the temperature and humidity requirements.

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

Temperature Relative humidity

0oC to 40oC (32oF to 104oF)

5% to 90%

2.1.2 Cleanness

Dust is hazardous to the operating safety of your device. Dust buildup on the chassis may

result in static absorption, causing poor contact of metal components or points. When indoor

humidity is extremely low, this is more likely to happen to shorten the useful life of the device and cause communication failures.

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

conductible dust as well. The following table lists the limits on dust particles:

By design, the router is ESD preventative; but excessive buildup of static electricity can still damage the card circuitry and even the entire device.

On the communication network connected to the router, static electricity is primarily introduced

from the outside electrical fields, such as the outdoor high-voltage power cabling and lightning,

and from the inside system, such as indoor environment, floor material and the equipment frame. To avoid damage, ensure that:

Chapter 2

z The equipment is well connected to earth. z The equipment room is dust-proof. z Maintain adequate temperature and humidity.

z Wear an ESD-preventive wrist strap and clothes when contacting the circuit

board.

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

into a static shielded 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 Compatibility

All interference sources, from the outside or from the inside of the router/application system,

adversely affect the router in the conduction patterns of capacitance coupling, inductance

coupling, electromagnetic wave radiation, and common impedance (including grounding system) coupling. To prevent the interference, do the following:

z Take effective measures against interference from the power 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 router far away from strong power wireless launchers, radar launchers

and high frequency and high-current equipment.

z Use electromagnetic shielding when necessary.

3Com Router 6000 Family

Installation Manual

Figure 3-8 Ethernet cable

Ethernet cables fit into the following two categories:

z Straight-through cable, at both ends of which, the wires are crimped in the RJ-45

connectors in the same sequence. The cable connects different types of devices,

such as a terminal device (PC for example) or router to a Hub or LAN switch. The network cables shipped with the router are standard cables.

z Crossover cable, at both ends of which, the wires are crimped in the RJ-45

connectors in different sequences. The cable connects the same type of devices,

such as PC to PC or PC to router. You can make crossover cables by yourself as needed.

Chapter 4

Starting and Configuring the Route

 Note:

In preparing network cables, shielded cables are preferred for electromagnetic

compatibility sake.

2) Fiber-optic Ethernet interface cable

For the 10/100/1000M Ethernet interfaces on the RPU2, select single mode or

multi-mode optical fibers depending on the type of the installed 1000Base-FX SFPs.

As the interfaces that these SFP modules provide use LC-type fiber-optic connectors,

you must use fibers with LC-type connectors for them. All these SFPs are hot

swappable.

 Note:

SFPs are optional. They are provided only when ordered.

III. Connecting the Ethernet cable

 Note:

The fiber-optic and electrical connections that a 10/100/1000 Mbps Ethernet interface

provides cannot operate at the same time. By default, if both connections are present,

the system considers the electrical interface as the operating interface.

Connect the electrical Ethernet interface cable Follow these steps to connect the cable:

3Com Corporation

Installation Manual

Starting and Configuring the Route

Step 1: Connect one end of the Ethernet cable to an Ethernet port on the router and

the other end to another device.

z For a 10/100 Mbps port provided by the RPU, connect it to a PC or another router

using a crossover cable or to a Hub or LAN switch using a straight-through cable.

z For a 10/100/1000 Mbps Ethernet port provided by the RPU2, either

straight-through or crossover cable can be used to connect to a Hub or LAN

switch because MDI/MDIX autocrossover is supported.

Step 2: View the LINK LED of the Ethernet interface: ON means a link is present. OFF means

no link is present; check the line for the cause.

1) Connect the fiber-optic Ethernet interface cable

Caution:

In connecting optical fibers, observe the following:

z Do not over-bend the fiber. Its curvature radius must be greater than 10 cm (3.9 in.). z Ensure that the Tx and Rx ends are correctly connected. z Ensure that the fiber ends are clean.

Chapter 4

Warning:

Laser danger: Invisible laser radiation may be emitted from the fiber-optic ports which

are connected with lasers. To protect your eyes against radiation harm, never stare

into an open fiber-optic port.

Follow these steps to connect a 10/100/1000 Mbps fiber-optic interface on the RPU2:

Step 1: Use two fibers to connect the Rx and Tx ends of the interface to another device: Rx to

Tx, and Tx to Rx.

Step 2: Power on the router and read the LINK LED of the interface: ON means the Rx link is present. OFF means no Rx link is present; check the line for the cause.

3.9 Connecting the Router to a WAN

Many types of WAN interfaces are available with the Router 6000 and the one provided by the

main control boards is an AUX interface. The following subsections describe how to connect it. For connecting the WAN interface on a FIC, refer to the relevant contents in the chapter “FICs”.
