INTRODUCING THE ROUTER 6000

FAMILY

Introduction 3Com 6000 Routers are next generation, high-performance edge routers. The

Router 6040 is a 4-slot chassis. The Router 6080 is an 8-slot chassis. 3Com 6000

Routers offer a robust hardware design, supporting Flexible Interface Cards (FICs),

hot swappable Power Supply Unit (PSU), and 1+1 power backup. Following are

the main features of 6000 Routers.

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. The ADSL cards available for 6000

Routers allow medium-to-small-sized enterprises to access the Digital Subscriber

Line Access Multiplexer (DSLAM) equipment via Public Switched Telephone

Network (PSTN) and then the Internet.

Asynchronous Transfer Mode (ATM) transmits, multiplexes, and switches

information in cells. 6000 Routers provide 155Mbps cards supporting ATM

Adaption Layer Type 5 (AAL5) and offering the traffic services like Constant Bit

Rate (CBR), Variable Bit Rate (VBR) and Unspecified Bit Rate (UBR). Hence, such

routers are well-suited to the high-speed data service and the transmission of large

8 CHAPTER 2: INTRODUCING THE ROUTER 6000 FAMILY

packets, which implement connection between medium-and-small-sized

enterprise networks and ATM networks.

MPLS Multiprotocol Label Switching (MPLS) is a combination of IP and ATM

technologies. This method replaces the IP header with a short and length-fixed

label as traffic identifier. This information is used by the router to make forwarding

decisions. This provides faster forwarding speed while getting support from IP

routed protocols and control protocols. This meets the requirements that various

new applications put on the network. MPLS VPN is a Virtual Private Network

technology that implements the interconnection of private networks via Label

Switched Paths (LSPs). As LSP is a tunnel across the public network on its own,

MPLS has an intrinsic advantage in terms of VPN implementation. 6000 Routers

usually act as Label Edge Routers (LERs) to connect to an MPLS domain with

non-MPLS domain or connect to MPLS domains of different service providers.

Data security and

reliability

■ Support for NAT. Besides some basic functions, the NAT available for 6000 can

limit concurrent connections to a single user, and thus alleviate the negative

impact caused by malicious resources without compromising the normal

network applications. NAT of 6000 also provides the ALG (Application Layer

Gateway) function to FTP and ICMP.

■ Support the authentication protocols such as PAP, CHAP, and data RADIUS

■ Implement packet filter and stateful firewall for preventing the intrusion from

an external networks.

■ Support VPN (including GRE, L2TP, and MPLS) and provide IPSec, and IKE,

hence ensuring the security of the private networks in an Internet environment.

■ Support the Backup Center and Virtual Router Redundancy Protocol (VRRP)

technologies, enhancing the robustness and reliability of the network by

providing a backup scheme in case of communication line or device failures. So

far, backup center supports backup load sharing.

■ Support hot swap of fans, interface cards, and power module to ensure high

reliability.

Online software

upgrading

You can upgrade the application programs and Boot ROM programs, and add new

features and functions on line as needed.

Abundant fault isolation

methods

■ You can monitor the states of system configurations, system service channels,

and system resources, as well as fault indication via console and network

management host.

■ You can monitor the FIC running state by observing the LEDs on FIC panels.

■ You can use in-service system test, out-of-service system test. In addition,

loopback test and hardware key module self-test are allowed.

Introduction to General Modules 13

Introduction to

General Modules

The 6000 Routers modules include RPU, PSU (PWR), FAN, and FICs.

RPU The RPU functions primarily to process protocols, forward low-speed packets,

control interfaces, and detect faults. The state monitoring information, such as the

operation states of FAN, PWR, and system can be shown directly via the LEDs on

the RPU, or reported to the network management system. In addition, RPU also

provides the hardware reset button RESET.

Ethernet interface

The RPU provides two 10/100Base-TX Ethernet ports on its panel (Ethernet 0/0/0

at left and Ethernet 0/0/1 at right). Their attributes are listed in the following table.

Table 7 Ethernet interface attributes

Power Modules The power modules of 3Com 6000 Routers can work in either single-power or

dual-power mode. In dual-power mode, the two Power Modules function in a

redundant; loading sharing mode. The input interruption or failure of a PWR does

not affect the operation of another PWR, and this operating PWR will provide all

the power required by the system.

Power Modules controls functions of overcurrent protection and overvoltage

protection.You can connect the PWR to the backplane by inserting it from the rear

of router chassis. It is hot swappable and its switchover will not affect the ongoing

system operation.

If you want to install a 6000 Router in a communication equipment room, you

should make sure that the power distribution cabinet can provide the lightning

protection box or arrester against the current of 20KA and above.

WARNING: Do not connect the AC power cord while inserting or removing a

card.

ON/OFF switch should be set to OFF while inserting or removing.

FAN The 6040 is configured with six fans, separated into three groups. The 6080 is

configured with eight fans, separated into four groups. The two fans in a group

work in a redundant manner. When all these fans are working normally, the

operating temperature of the system can be maintained in the range of 0 to 55 C.

Failure of a fan will not affect the operation of other fans, the system will still be

able to operate in the normal temperature. The rotating speed of the fans is

controlled by the RPU and is in the range of 50% to 100%.

The FAN controller uses two parameters, i.e., low-temperature threshold and

high-temperature threshold to control the rotation speed of the fans, with the

former corresponding to 100% rotating speed and the latter corresponding to

50% rotating speed. The system will send out rotation stop alarm signals in case

any fan fails. The alarm and state LEDs of FAN are located on the RPU front panel.

INSTALLING THE ROUTER

General Site

Requirements

To ensure the proper working of the routers and prolong their service life, the

installation site should meet the requirements described in the following sections.

Temperature/Humidity

Requirements

To ensure normal operation of the Router, the equipment room must maintain

temperature and humidity. Long-lasting moisture can degrade the performance of

the insulating material, which may result in electric leakage, leading to metal

erosion. The following table lists the requirements of 3Com Router 6000 in

temperature and humidity.

Table 1 Temperature/Humidity requirements in the equipment room

The values of the operating temperature and humidity in a router equipment

refers to the values measured at the position 1.5m above the floor and 0.4m

ahead of the router rack, given there are no protective boards in front or at the

back of the router rack.

Cleanliness

Requirements

Dust is harmful to the safe operation of the Router. Dust on the chassis may result

in static absorption, and causes poor contact of the metal connection components

or points.

There should not be explosive, conductive, magnetic and corrosive dust in the

equipment room where 3Com 6000 Routers are located, and the dust

concentration should meet the following requirements:

Table 2 Limitation on dust content in equipment room

Besides the dust specifications, the equipment room of the Router should also

meet the rigorous requirements for the content of salt, acid and sulfide. These

harmful gases could accelerate the metal erosion and the aging process of some

parts. The specific limits of these harmful gases are given in the following table.

Figure 1 Harmful gas limits in an equipment room

ESD Preventive

Requirements

Despite careful considerations in preventing ESD in the design of the Router,

excessive static electricity may bring enormous damage to the card circuits and

even the entire Router.

On the communication network connected to the Router, the static electricity is

primarily introduced from the outside electrical fields, such as the outdoor

high-voltage power cable and lightning, and from the inside system, such as

indoor environment, floor material and the equipment frame. To avoid the

damage caused by the static electricity, you should ensure that:

■ The equipment is well connected to ground.

■ The equipment room is dust-proof.

■ There is adequate temperature and humidity.

■ You always wear the ESD-preventive wrist strap and clothes when contacting

the circuit board.

■ You place the removed circuit board upward on the ESD-preventive

workbench, or into a static shielded bag.

■ You hold the circuit board by the outer edge when observing or moving it, so

as to avoid direct contact with the elements on it.

Electromagnetic

Environment

Requirements

All interference sources will affect the Router negatively in the conduction patterns

of capacitance coupling, inductance coupling, electromagnetic wave radiation,

and common impedance (including grounding system) coupling. To prevent the

interference:

■ Take effective measures against electricity net interference with the power

supply system.

■ Do not use the working ground of the Router together with the grounding or

lightning protection grounding device of the power equipment. Separate them

as far as possible.

■ Keep the Router far away from strong power wireless launchers, radar

launchers and high frequency and high-current equipment.

■ Use electromagnetic shielding if necessary.

Lightning Protection

Requirements

Despite careful considerations have been taken in lightning protection in the

design of the Routers and measures have been adopted, excessive-degree of

lightning may still damage the Routers. To achieve the best lightning protection

effect, you are recommended to:

■ Keep the grounding wire of the PGND of the chassis in good contact with the

earth ground.
