THE GROWINGNEED FOR ENERGY

EFFICIENCYBusinesses are increasingly concerned about how muchenergy their network infrastructures use. Energy costs are an

ever-increasing component of overall operational expenses,

and they adversely affect the bottom line. Deploying more

energy-efficient technologies would seem to be a simple

decision. But companies must weigh energy savings against

performance and productivity requirements.

Businesses want to support the environment, but they know

that ensuring the integrity of their networks and keeping the

total cost of ownership low is vital to staying competitive. They

want products that not only deliver power savings, but also the

best performance and reliability. Controlling energy use is

critical to meeting these requirements, particularly given the

estimate from IDC, a global provider of market intelligence,

that the cost of powering and cooling data centers will increase

from $26 billion in 2007 to $44 billion globally by 2010.

3Com is committed to

maximizing customers

productivity while mini-

mizing the environmental

impact of their networks.

As a member of The Green Grid, a global consortium that promotes

energy efficiency in data centers and business computing eco-

systems, we are actively involved in efforts to standardize ways

of measuring energy efficiency. Through our membership, we

influence and vote on initiatives that complement our participation

in the IEEE 802.3 Ethernet working groups activities, especially

its P802.3az Energy-efficient Ethernet Task Force.

DELIVERING ON THEGREEN CHALLENGE3Com helps customers realize the financial benefits of updating

their systems to more energy-efficient models that deliver out-

standing reliability and performance. Our current generation of

switches use up to 78 percent less power than previous versions.

Independent research by In-Stat found that 3Coms local area

network (LAN) switches are up to 60 percent more energy

efficient, or green, than competitors products. The report,

Green Networking Equipment: Who Leads and Who Lags,

finds that in addition to being the most energy-efficient, 3Coms

switches far outpace the rest of the industry by delivering more

fabric capacityGigabits per secondper watt of electricity used.

The report says there are significant differences in the energy

efficiency of similarly equipped switch equipment and that as

many businesses develop green initiatives ... IT managers willbe forced to absorb some degree of responsibility for their

organizations power usage.

With the introduction of the 3Com Switch 7900E / H3C S7500E,

which according to public data is up to 75 percent more energy

efficient than the equivalent Cisco Catalyst 6500 switch, 3Com

has further enhanced its green credentials.

Product Life Cycle Processes for ReducingEnergy Consumption

According to industry research, slightly more than 1 percent of

the electricity consumed by commercial buildings is used by

networking equipment.

As network energy consumption grows, our engineers continue todevelop innovative methods for reducing power usage without

impacting operational performance or functionality. For our

customers, this means transporting more data for less money.

Some 3Com- and H3C-branded products even feature hybrid

electrical and optical interfaces on a single circuit board to reduce

customers investment in hardware and related system power

consumption. And we are working on ways to detect the length of

network cables so only the amount of power required is actually

supplied and used.

that 3Coms local area network

switches are up to 60% more energy

efficient than competitors products.

are alert to the consumption of raw materials such as plastics,

metals, water and other key resources. And we avoid using

excess material that adds to a products weight to help reduce

shipping-related CO2 emissions.

We focus on ensuring resilience and minimizing environmentalcontamination. These efforts include the work of a specialized

team dedicated to advancing product reliability and energy-

saving thermal design. Early in the development cycle, strict

reliability specifications are defined and procedures such as

failure mode and effects analysis (FMEA), highly accelerated

life test (HALT), thermal emulation and thermal testing are used

to improve product reliability and thermal performance. In the

manufacturing phase, a highly accelerated stress audit (HASA)

is used to further enhance product reliability and strength.

Thermal Controlled and Fanless CoolingIn addition to reducing power use, heat generation and coolingrequirements, our innovations let systems dynamically detect

when fans can run at lower speed. In periods where ambient

temperature is low or network traffic is light, these systems

reduce the typically large amounts of energy that fans consume.

To further reduce power use, 3Com offers fanless products,

including the OfficeConnect, Baseline and Switch 4200 families.

Leveraging Advanced Silicon TechnologyMost 3Com and H3C products use 90-nanometer silicon

technology (90-billionths-of-a-meter transistors) to deliver

highly advanced functionality without increasing power usage.

Innovations in reducing leakage current let the most recent 90-

nm processors deliver a 35 percent increase in speed while

cutting active power needs by 60 percent. We also produce an

increasing number of products that use even more energy-

efficient 65-nm silicon, and we have plans to take advantage

of 45-nm technology, which will reduce power consumption

by an additional 30 percent.

Increasing Power Supply EfficiencyInefficient computer power supplies waste approximately 30 to

40 percent of the electricity consumed. Much of this wasted

energy is converted into heat, requiring larger cooling fans.

As seen in this comparison chart, moving to newer technology can provide significant savings for an organization with a typical network (100

Ethernet switches and approximately 2,000 networked nodes). For example, by replacing an older 3Com switch such as the Switch 4900 with the

3Com Switch 4500G/5500-SI, an organization could realize savings that correspond to:

79, 890kwh, the equivalent of lighting 62 homes for one yearBased on EPA date indicating 1,250 kwh per year for lighting an average home

3Com- and H3C-branded switches use power supplies with 80

percent or better efficiency under full load. A number of our

switches also support DC connections to dedicated power racks,

which are an even more energy-efficient option.

Power Savings from Control of Port Modesand Power over EthernetEthernet ports on some of our switches can adopt a sleep mode

in which they automatically shut down if there is no data link.

When there is data transmission, the ports automatically resume

normal activity.

The technology we use enables customers to take advantage of

intuitive Power over Ethernet management where full power on

each port is not required. Network managers can determine

the total power budget by setting a switchs maximum power

output based on what is connected to a port. These initiati vesenable the design of smaller and more efficient internal power

supplies. And for customers who need full power, the external

DC system offers a highly resilient and, most importantly, 90-

percent efficient electrical conversion.

MAKING A DIFFERENCE

Regulatory Compliance3Com-branded and H3C-branded products comply with or exceed

the European Unions RoHS Directive (the restriction of the use

of certain hazardous substances in electrical and electronic equip-

ment), which bans sales into the EU of new equipment containing

excessive levels of lead, cadmium, mercury, hexavalent

chromium, polybrominated biphenyl (PBB) and polybrominated

diphenyl ether (PBDE) flame retardants. And shipments of our

products to China comply with China-RoHSthe China

Ministry of Infor- mation Industry Order #39, Administrative

Measures on the Control of Pollution Caused by Electronic

Information Products.

We enforce guidelines for removing hazardous substances and

comply with the WEEE (Waste Electrical and Electronic Equipment)

directive, which makes producers responsible for disposal and

recycling of their products.

As an ENERGY STAR partner, 3Com is part of a global effort to

help customers save money and protect the

environment through energy-efficient

products and practices. For example, the

power adapters we design to be ENERGY

STAR compliant are lighter, smaller and on

average 30 percent more efficient than

conventional models.

Manufacturing Processes3Coms engineering teams minimize the discrete component

count on printed circuit boards to reduce the raw materials

consumed and save power. We also use texture mapping rather

than printing, electroplating or bronzing to reduce materialsuse. And we use recyclable materials whenever possible in

component manufacturing.

To limit waste, we minimize the physical dimensions of our

products. Simple package design further reduces materials

use and facilitates recycling activities. And sea rather than air

transport is the preferred choice for global distribution of 3Com-

and H3C branded products for additional energy savings and

reduced environmental impact.

Product documentation is published online, which eliminates

printed materials, reduces shipping weight and saves an average

of 10,000 trees a year. This calculation is based on a standard

stack of wood that measures 4 feet wide x 4 feet high x 8 feet

long, that can produce 90,000 sheets of paper and 1.8 million

product shipments per year with 500 pages per document pack.

Safety and Recycling DesignBecause recycling is such a critical environmental issue, our

New Product Introduction Process requires the selection of

materials that can be effectively recycled. The companys

recycling and anti-pollution initiatives include:

Eliminating added SCCP flame retardants and plasticizers Eliminating in large plastic product parts certain flame

retardants classified under European Council Directive

67/548/EEC

Eliminating lead, cadmium and mercury from batteries

Eliminating PVC from large plastic product parts

Identifying materials with special handling needs

Eliminating paints or coatings that are not compatible with

recycling or reuse

Identifying and removing components with hazardous

materials

Eliminating or removing molded/glued-in metal

Eliminating intentionally added toxins in packaging

Enabling easy disassembly of external enclosures

Allowing manual separation of plastics

Reducing the number of plastic material types

Ensuring separability of packing materials

Using a standard minimum 65 percent reusable/recyclable

materials
