PSA-3000 & PSE Conformance Test Suite

The PSE Conformance Test Suite for the PSA-3000 produces over 130 PoE test parameters per PSE port depending upon PSE capabilities.   These parameters are measured in 23 distinct tests that may be selected and sequenced across up to 24 PSE ports at a time. The test covers over 95% of the PSE PICS (conformance check list items) in the IEEE 802.3at specification*. The PSE Conformance Test Suite is widely used throughout the internetworking community as the industry “norm” for PSE specification compliance.

The PSE Conformance Test Suite for the PSA-3000 provides:

  • Robust 802.3at (PoE+) PSE Compliance Testing
     
  • Fully Automated Port Sequencing and Statistics for up to 24 PSE Ports
     
  • Greater than 95% 802.3at PICS Coverage from 23 Tests Producing up to 137 Test Parameters per PSE Port
     
  • Fully Emulates All Type-1 (PD Class 0, 1, 2, or 3) and Type-2 (PD Class 4) PD’s Including LLDP-Capable PD’s
     
  • Adapts to All Prevalent PSE Signaling and Power Behaviors
     
  • Adapts to Prevalent Composite 802.3at and Proprietary Detection Signaling Behaviors
     
  • Configurable Waveform Trace Diagnostic Generation and Retention to 10 Waveforms per Test
     
  • Colorful and Informative Spreadsheet Reporting with Compliance (Pass/Fail) Notations and Parameter Statistics

PSA-3000 & PSE Multi-Port Suite

The PSA-3000 supports an optional feature for Multi-Port system testing and analysis of PSE's.   This type of testing is primarily useful for development and analysis of PSE system-wide behaviors such as the distribution of power to one or more Powered Devices.   It can also be an efficient means for QA of higher (24 and up) port-count PSE's.

At the heart of Multi-Port system testing is the ability to present user-defined Powered Devices on many or all PSE ports simultaneously.  Using Live PD Emulation, every PSE port can experience any user-defined PD including Type-2 (Class 4) PD's with full LLDP support.   Live PD Emulation means a user-defined PD is always present regardless of the state of the PSE port.  PSE ports may administratively remove power, restore power, negotiate power, and re-nogotiate power as they choose.

The PSE Multi-Port Test Suite is a group of 16 tests that emulate user-defined Type-1 (Class 0-3) PD's across many or all PSE ports in order to assess PSE behaviors such as power administration by port, total power capacity, group power-up, shutdown, and overload timing, port interactions and interdependence, and power stressing over time.  Though the PD emulations are exclusively Type-1, these tests are applicable to both Type-1 and Type-2 (high power) PSE's as they are not in any way bound to PoE LLDP protocol rules.Key features of the PSE Multi-Port Suite for the PSA-3000 are:

  • Configure up to 192 ports of simultaneous Live PD Emulation with per-port Live Status monitoring
  • Live PD Emulation of Type-1 (Class 0-3) and Type-2 (Class 4), including LLDP-Capable Powered Devices and 4-Pair (proprietary) High Power Devices
  • Up to 192 Ports of fully automated Type-1 (non-LLDP) system testing and analysis including power management decisions, power capacity, multi-port startup / shutdown / overload timing analysis, and multi-port interactions including port voltage perturbations.
  • Colorful and Informative Spreadsheet Reporting with Compliance (Pass/Fail) Notations and Parameter Statistics

PSL-3000 & PSE Multi-Port Suite

The PSL-3000 Programmable Load supports an optional feature for Multi-Port system testing and analysis of PSE's.   This type of testing is primarily useful for development and analysis of PSE system-wide behaviors such as the distribution of power to one or more Powered Devices.   It can also be an efficient means for QA of higher (24 and up) port-count PSE's.

At the heart of Multi-Port system testing is the ability to present user-defined Powered Devices on many or all PSE ports simultaneously.  Using Live PD Emulation, every PSE port can experience any user-defined PD including Type-2 (Class 4) PD's with full LLDP support.   Live PD Emulation means a user-defined PD is always present regardless of the state of the PSE port.  PSE ports may administratively remove power, restore power, negotiate power, and re-nogotiate power as they choose.

In combination with the PSL-3000, the PSE Multi-Port Test Suite is a group of 9 tests that emulate user-defined Type-1 (Class 0-3) PD's across many or all PSE ports in order to assess PSE behaviors such as power administration by port, total power capacity, port interdependence, and power stressing over time.  Though the PD emulations are exclusively Type-1, these tests are applicable to both Type-1 and Type-2 (high power) PSE's as they are not in any way bound to PoE LLDP protocol rules.

Key features of the PSE Multi-Port Suite for the PSL-3000 are: 

  •  Low per-port Cost

  • Configure up to 192 ports of simultaneous Live PD Emulation with per-port Live Status monitoring
  • Live PD Emulation of Type-1 (Class 0-3) and Type-2 (Class 4), including LLDP-Capable Powered Devices and 4-Pair (proprietary) High Power Devices
  • Up to 192 Ports of fully automated Type-1 (non-LLDP) system testing and analysis including power management decisions, power capacity, and multi-port independence tests
  • Colorful and Informative Spreadsheet Reporting with Compliance (Pass/Fail) Notations and Parameter Statistics

LLDP Emulation & Analysis for PSA-3000 & PSL-3000

LLDP Emulation involves modeling numerous characteristics of a PD as it uses LLDP to request and agree upon power allocations from a PSE.   Normally, such transactions are performed immediately after powering the PD, though they may be ongoing with subsequent power adjustments induced by either the PD or the PSE.   Characteristics that may be modeled are PD Power Request, PSE Power Allocation (echo), periodicity of packet transmission, timing of responses to value changes, LLDP time-to-live, and various TLV fields that communicate device status and information.

LLDP Analysis involves capturing and analyzing bi-directional PoE-specific LLDP packets and associated packet timing during PD power-ups and during ongoing (post power-up) power adjustments.
