Cable Quality and Life Cycle

Choosing the Appropriate Cabling Media

–ipAssured Program

�The Effects of Heat to the Cabling System

�Current and Future Applications : Being Ready

4

� Ip-Assured Program: Flexibility with respect to supported services and useful life of cabling infrastructure

� Making Life Cycle Choices Easier

� Headroom is vital

� Equipment vendor recommendations or specifications

� Channel capacity within the cabling system (especially for the Data Center)

� Category 6 minimum recommendation for horizontal cabling. Should already adopt CAT6A for Data Center Cabling

� 50/125 micron 850 nm laser optimized multimode fiber is recommended for most backbone applications

� OM3+/OM4 is already ratified

Choosing the Appropriate Cabling Media:

System losses can affect the network’s performance

Infrastructure Assurance Lab Tests

� Conclusions from Lab tests:

– Cable standards for performance are measured at 68˚ F (20˚ C)

– Category 5e fails at 113˚ F

– A 1˚ degree rise in ambient temperature = a .6% increase in insertion loss

– PoE and PoE+ internal temperatures are additive to loss

– Cable bundles add additional stress

� Security Infrastructure Considerations

– How does a cabling system perform under less than ideal conditions?

– What constitutes the need for better than minimum?

– How can I justify the additional cost of a utility grade infrastructure?

The Environment: A Social Responsibility

–Green Initiatives:

�Weather Chaos

�Waste Management: Earning LEED Points

�Saving on Power: Simple Thermal Management Techniques

� Osang

� Nitang

� Milenyo

� Juan (Meji)

10

What is it all about? Can We Still Ignore It

� Being Efficient = Lesser Power Consumption

� Green House Gas Emissions =Global Warming

� Using Cleaner Sources of Energy = Lesser Carbon Emissions

� Reduce, Reuse, Recycle

11

Waste Management: Where Can We Help?

� There are services that can acquire LEED points related to:

–Sections 2.1& 2.2 for Construction Waste Mgt.

�Divert waste from the job site and landfills

�Measure diverted waste according to the LEED-approved conversion factors

�Recycle packaging material

�Provide LEED-approved reports & compliance proof from recycling partner

12

Saving on Power: Basic Facts on Cooling System

� 1 Watt of power consumed = 1 Watt of heat

� 83% of data centers have Power / Heat problems

� Power consumption doubled between 1998 & 2003

� Heat will seek cold before it rises

� Common: to cool the room, will cool the equipment

� Water removes heat 3467 times more efficiently than air

� Static pressure drops with one open floor tile

� Average data center has 2.7 times more AC than equipment needs…. This is where “being efficient”needs to kick in

Other Passive Solutions : Isolated Return Air Path (Hot Air Isolation)

� Hot air is segregated with return air ducts� Rear door is “sealed” to prevent exhaust air from leaking into room

� Air Dams in front of cabinet prevent air recirculation inside cabinet

� Room A/C is easy to manage, with little regard to concentrated heat loads

� Cabinets can be placed and oriented any way desired

� Cold air delivery can be shared throughout room with fewer “zone” issues

� Total Heat Load Dissipated = 22 Kilowatts

Going Back to Basics: What is Static Pressure?

�Pressure of a fluid whether in motion or at rest. It can be sensed in a small hole drilled perpendicular to and flush with the flow boundaries so as not to disturb the fluid in any way.

26

Open Floor Tiles Dramatically Reduces Static Pressure

27

Raised Floor Filler/Brush Panels

28

� Floor vents in a raised floor environment

– Proximity of floor vents to supply source

�Never closer than 8 ft

– As velocity decreases, static pressure increases

ANSI/TIA/EIA-607, ITS Grounding and Bonding

63

A flash of lightning

is often followed by

a gut-wrenching

crash…

The trouble is, it’s

not always thunder!

64

� …improper grounding of communication systems leads to $500 million / year of damage to property and equipment due to lightning (Insurance Industry Data)

� 27-33% of damaged equipment is caused by electrostatic discharge

� IEEE states, the typical AC third prong earth is almost never sufficient to prevent damage to network equipment

What are the effects of improper grounding?

66

Grounding & Induced Voltages

67

What is an Electro-Static Discharge (ESD) Event?

When a non-grounded conductor of static charges -a person or an object - comes close to a ground plane, the charge will “jump” from a point on the non-grounded conductor to the grounded object,

causing an ESD event.

68

How Much Static Does it Take?

Here are some examples of how much static electricity is generated by simple actions:

69

Why Should I Care About ESD?

Below is an example of a catastrophic ESD event

� Case Studies

– Call Center Burning Headset Problem

– Call Center Noise Problem

– Educational Institution FM Problem

70

ESD Damage - 1

This is not Human Body Model (HBM-ESD). Extensive damage on this transistor where the bond has melted is typical of surges from Inductors, Transformers and Motors.

71

ESD Damage - Summary

�In the previous slide, the damage could have prevented by proper grounding and bonding

�The unseen damages are the ones that can cause the most harm

�Grounding and bonding goes hand-in-hand with a managed ESD control program

�Can you afford not to ground properly?

�Do you have an effective ESD Control program?

�Can your systems and data survive if you don’t?

�What will the impact to your operations be and how will it affect the bottom line?
