Survey Solutions for Powered Device Verification

This 10 minute video surveys challenges of designing, building, qualifying, and troubleshooting PDs in a design, fabrication, and end-user (IT) environments.   Sifos Powered Device (PD) testing solutions are reviewed.

Are handheld Ethernet and PoE testers useful for testing PoE PDs?

Simple answer:  NO.

Handheld Ethernet cable analyzers, PoE detectors, and in-line PoE monitors have no ability to resolve whether any Ethernet Powered Device (PD) will properly interoperate with 802.3 compliant PSEs in all connection environments.  These products should not be mistaken as PoE PD testers.

Specification Conformance

Verify that a PD conforms to 802.3at or 802.3bt standards to assure interoperability

Conformance to IEEE 802.3at or 802.3bt standards is necessary to assure PD interoperability  with all PSE’s in all connection environments while also assuring safe and reliable operation.  PD designers are challenged by the complexity of IEEE PoE standards and by the fact that PD controller components, by themselves, do not assure a conforming powered device. 

Product Recommendation
802.3at PD Conformance Test Report

Powered Device Analyzer + PD Conformance Test Suite

  • Fully automated, one-click, plug'n play testing of all critical PD conformance parameters

Automated Manufacturing Test

Manufacturing & Volume QA

Avoid quality issues in the field by automating acceptance tests for PDs.

Whether your final test strategies involve highly resolved PD analysis and debugging or high volume qualification of essential PD interoperability requirements, Sifos offers a variety of solutions including flexible test automation development tools.

Product Recommendation

Resolved PD analysis and troubleshooting of any 802.at or 802.3bt PD

Leverage the resources of the world’s only 802.3 PD Conformance Test instrument combined with PowerShell PDA Software to engineer highly customized test automation for QA / manufacturing settings.

  • Intuitive, high level, interpreted scripting language
  • Standard feature of all PDA-600 instruments
  • Extensively documented with built-in command help
  • API access (DLLs) to work in the Windows programming language of your choice
Product Recommendation

Volume QA and final inspection of Class 0 – Class 8 PDs to assure interoperability

Testing multiple PDs simultaneously, pick a strategy and leverage off-the-shelf GUI managed software or develop specialized automation to gain confidence in the interoperability of your PDs.

MPD-600 Automation Development Software
MPD Interactive Group Interop Test Menu – Simultaneously test up to 6 Powered Devices
  • Test up to 6 PDs simulataneously
  • Interactively operate PDs as PoE testing runs
  • Intuitive, high level, interpreted scripting language
  • Extensively documented with built-in command help
  • API access (binary libraries) to work in the programming language of your choice
  • Work with Windows or Linux PCs
PoE LLDP Test

PoE LLDP Emulation

Verify that a PD properly negotiates power and operates within LLDP negotiated power budgets.

If your PD utilizes Link Layer Discover Protocol to negotiate power with a PSE, testing for compliance to the LLDP portion of the 802.3at or 802.3bt standard will be just as important as any other aspect of conformance testing.   All 802.3at Type-2 and 802.3bt Class 4-8 PD’s are required by their respective standard to support PoE LLDP power negotiation.

Product Recommendation
PDA Interactive LLDP Menu

Powered Device Analyzer + LLDP Emulation Option

  • Flexibly emulate Type-2, Type-3, and Type-4 PSE's that utilize LLDP for power management
  • Assess protocol and message timing conformance to 802.3at and 802.3bt standards
  • Control basic protocol parameters including PSE type, capabilities, and TTL
  • Colorful spreadsheet reporting of protocol and timing violations
  • Utilize LLDP to negotiate and validate power draw compliance during the PD Conformance Test Suite and with the Load Monitor

End-User Qualification and Troubleshooting

Easily sort apart PD interoperability issues from PoE switch / cable plant problems in end-user environments

Whether qualifying new PDs for service or troubleshooting existing PDs experiencing powering instability, imagine a specialized PSE that with a simple, patch cable connection evaluates PD interoperability in all connection settings.

Product Recommendation

Plug and test up to 6 PDs at a time and let a specialized PSE do the work….

Physical Layer Integrity

Physical Layer Integrity

Asses LAN Physical Layer Integrity at the PD while powered by a PSE.

Much like PSE ports, PD 10/100/1000Base-T interfaces must function in all connection environments with DC power sharing the same wires.  

Product Recommendation

PhyView Analyzer + PHY Performance Test Suite

  • Automated, one-click analysis of PoE induced signal impairments via mechanism of DC current unbalance.
  • Measure transmitted SNR and low frequency power spectral distortion
  • Assess receiver performance with physical impairments including worst case insertion loss and ingress noise
  • Utilize with passive power injector that can furnish either 2-pair or 4-pair power to PD
