Today’s Call• Power-over-Ethernet (PoE) is a name, not a
standard!
• IEEE 802.3 Standards-based and non-standards-based PoE solutions exist today.
• What is the industry interest in creating a logo certification program for implementations of IEEE 802.3 “DTE Power via the MDI” Standards?

Accelerate Market Adoption
• Dot3PoE logo program would
indicate:
▫ Predictable Ethernet power and
data delivery using IEEE 802.3
standards
▫ Confidence in interoperability
▫ Device reliability and safe for

Some bad apples…NEGATIVE/ERRONEOUS COMMENTS FOUND ON AMAZON ABOUT
PoE PRODUCTS
• Review - Despite the specs and the connector "appearing" to be
compatible with the F---------, this did not deliver power on a 10 foot
run. A definite waste of money.
• Review - I wanted to use this device on a 50 feet Ethernet cable
going to a camera. It worked fine on much shorter cables (well under
10 feet) when I tested but luckily I tried it on a 50 foot cable before
counting on it and installing. It didn't work and I just decided to put
an outlet out by my camera to provide power.
• Review - Bad Engineering - Ethernet Portion does not work
• Review - Would not buy. Ethernet did not work
• Review - Gigabit Ethernet uses all 4 wire pairs as data lines, so it is
not possible* to have Gigabit Ethernet and PoE on the same
cable. MISINFORMATION

Challenges to Interoperability Device Types Challenges Impact
Power Sourcing Equipment
(e.g. switches, PoE injectors)
• Power delivery over distance• Short circuit protection• Voltage & current sensing• Pairing correct capability of PSE
with powered device • User dissatisfaction • Device damage• User safety
PoweredDevices
(e.g. phones, cameras, sensors)
• Power draw within ‘standard’ limits
• Safe for use in networked environments
• Power management• Short circuit protection

Certification shouldn’t be a burden
• Should fit the market needs
▫ Not a checkbox exercise
• Variables can be controlled
▫ Cost
▫ Complexity of Testing
▫ Self-Declaration vs Third party

Certification will provide benefits

Next Steps• The Ethernet Alliance is evaluating industry interest & need before
proceeding with a program launch
Should the Ethernet Alliance establish a logo certification program for Power over Ethernet products?
