• Improve employee or customer engagement and satisfaction

• Converged building infrastructure

– Connect everything over Ethernet network

– Easy to move lights and other endpoints

– Software driven changes

• Analytics improve business


• What is it?




Current State of Digital Building

• Infant stage – few actual use cases

• ROI is difficult to measure

– Lower labor rates for LV electricians

– Cost/port estimated to be $100

– Most savings realized on transfer to LED

• Hardware, sensors and software are available today

• Cisco driving. Siemens and Johnson Controls are resisting.

TSB-184-A Overview

• Revision of old document to support higher power and current levels

• Tested multiple cable bundle sizes

• Measured temperature rise in center of bundle

• Limit temperature rise to less than 15oC above ambient

• Temperature rise can:

– Cause signal degradation (e.g., attenuation)

– Cause long-term damage if temperature exceeds cable rating

Actual Results from TSB-184-A Testing

• 100-cable bundles

• Cat 6 and 6A, 28, 26, and 23 AWG performance with PoE

• Implications:– All AWGs work, have different bundle size limits

– All AWGs will have different temp rises for different bundles sizes

– Cat 6A has best performance

* Assumes 10 meters of patch at 20 degrees CFrom ANSI/TIA-568-C.2, Table G.2

▪ Additional insertion loss at higher

temperature de-rates maximum

channel lengths

▪ Conservative values

▪ Use vendor headroom

warranties to estimate

performance

▪ Consult cable vendor for specific

performance

What is the Impact to You?

• Heat of cable governed by:– Ambient temperature

– Type of PoE used

– Category cable type (and its implementation)

– Bundle size

• Insertion Loss affected by Heat

• Therefore, can a relationship be established between bundle size and channel length?– For a given ambient temperature, and assuming 4PPoE type 4?

Putting it all Together

▪ Use the channel table to compute effect

of temperature rise to channel length

▪ Model shows 7.8oC improvement with

Cat 6A over Cat 5e

– Cat 5e exceeds 15oC limit

– 7.8oC translates to a loss of ~3 meters

▪ Measured shows 13.4oC improvement

with Cat 6A over Cat 5e

– 13.4oC translates to a loss of ~5 meters

▪ Recommendation: INSTALL CAT 6A!

5m loss!

Cat 6A is more efficient

• Cat 5e = more heat = more power lost

• Cat 6A is more efficient– Larger wires, less heat, more power transferred

• How efficient?

Cable Type Power Lost

Category 5e 24.4 W

Category 6A 20.1W

Category 6A is 4.3 W more

efficient per link!





Impact of 2017 NEC® Code• Generally does not apply for power supplied over a

communications cable when power levels are 60 watts or less

– Applicable for PoE++, Type 4

– Not applicable for PoE++, Type 3 and lower

– 60 W covers vast majority of installations

• Recognizes a new UL listing for Limited Power (LP) cables

– LP listed cables are NOT required to run PoE

– If you do not have LP listing, you have to watch bundle sizes per ampacity table

• Uncertainty on how inspection will work

– Likely will vary by state and local interpretations

– Speculation: Inspections may occur by application type

When will the 2017 NEC® Apply to Me?

▪ Depends on state

▪ Some states do not

have statewide

adoption

▪ Some states 1 or 2

versions behind

▪ Code is always open to

interpretation at a

local/state level!

If the NEC® 2017 Requirements Apply

You are running IEEE802.3bt Type 4 PoE++

Either:

• Use a LP listed cable rated to at least 0.5A

OR

• Refer to ampacity table 725.144 for bundle size. Bundle size depends on:– Cable Temperature Rating

– Wire Gauge

– Ambient temperature

Ampacity Table

For common 23AWG cables:

• Maximum bundle size for a 60oC rated cable running 802.3bt Type 4 is 91 cables

• Maximum bundle size for a 75oC or 90oC cable running 802.3bt Type 4 is 192 cables
