Power Over Ethernet Review Perle PoE Media Converters Other product news Q&A
What is Power Over Ethernet • Power Over Ethernet is a standards-based method of supplying power to network devices over standard Ethernet UTP/STP copper cable •
Commonly referred to as “PoE”
•
Power Sourcing Equipment – “PSE” • PoE switches • Midspan power injectors
•
Powered Devices – “PD” • Wireless AP’s, Network IP cameras, thin client, displays, etc
Benefits of PoE Cost Saving - PoE saves time and money by avoiding the need for separate installation of Data and Power infrastructures.
Simplicity – Power is fully integrated with Ethernet infrastructure, so access to difficult for power deployment areas, such as ceilings, becomes simpler. Mobility - Powered devices (PDs) can be easily moved without need for AC outlets, minimizing business disruption. Wherever there is an Ethernet connection, a PD can be easily deployed. In addition, PoE will accelerate the deployment of wireless access points and network cameras because power, which is rarely available above the ceiling, can now be offered over the Ethernet cable. Safety - no mains voltages usage, only safe direct-current 44 - 57V levels ( low voltage )

Power over Ethernet Standards •
•
IEEE 802.3af standard ( PoE ) •
Ratified in 2003
•
Allows up to 15.4 W output power ( 12.95 W @ PD due to power loss across a 100m cable )
• 44 – 57V DC range ( output voltage at PSE ) IEEE 802.3at standard ( PoE+ ) •
Ratified in September 2009
•
30 Watts ( 600mA at 50vDC ) output power ( 25.5 watts at PD due to power loss across a 100m cable)
•
50 – 57V DC range ( output voltage at PoE )
PoE+ Applications •
IEEE 802.3at standard •
Sometimes referred to as “PoEP”, “PoE Plus” and “High PoE””
•
Backwards compatible • •
•
802.3at ( PoE+ ) Type 2 devices 802.3af ( PoE ) Type 1 devices
Same applications as PoE but with higher power PDs •
PTZ (pan-tilt-zoom) cameras
•
802.11n wireless access points with dual radios
Cisco AP1250
AXIS P5532/-E
Cisco Catalyst 4500
PoE Twisted Pair Powering Options • Standards-Based •
IEEE Alternative A (pins 1,2 and 3,6)
•
IEEE Alternative B (pins 4,5 and 7,8)
• Pre-Standard support • Legacy proprietary ( Cisco VoIP ) (pins 4,5 and 7,8; reverse polarity) • Legacy non-IEEE Large-capacitance detection method
PoE Discovery
PSE detects if the PD has the correct signature resistance PSE detects classification current indicating power range ( Class 0 – 4 ) Controlled start-up voltage ramp up Normal operation Disconnect

PoE Media Converters - Integrating PoE and Fiber •
Use PoE/PoE+ Media Converters •
Converts copper to fiber
•
Power is injected over copper •
•
PoE IS NOT injected over Fiber
•
Its a fiber to ethernet media converter and a PoE injector in one device
•
Fiber is run to the power source, and PoE is distributed over Cat 5 to the Powered Device.
Leverage the Benefits of Fiber •
Longer Distances
•
Higher Bandwidth/Capacity
•
Security
•
EMI protection – inter-building connections
•

Redundant Fiber uplink feature on dual fiber models •
Disabled as a default ( operates as a multiport switch )
•
Redundant Fiber : When the primary link fails, the media converter redirects traffic to the other fiber port within 50ms
•
Redundant Primary : When the primary link fails, the media converter redirects traffic to the secondary fiber port within 50ms. Upon restoration of the primary fiber link, traffic is automatically redirected back to the primary fiber
