PoE End-Point, Mid-Span PSE, Chip, Powered-Patch Panel, and Integrated Modular Connector Development…. IEEE 802.3 PSE Compliance and DV Test…. Engineering and Manufacturing Script Development Tool…. Portable PoE Service Analyzer

Overview Power-over-Ethernet (PoE) challenges design and test engineers to evaluate multi-channel, low power DC sources that are activated and deactivated through signaling protocols while supporting several power delivery and polarity configurations. The application and management of DC power over many local area network connections must be completely transparent and non-disruptive to the traditional data transmission functions of those network connections.

The PSA-100 is a powerful, yet compact instrument for fully characterizing and testing PoE parameters on one or two PSE ports. The PSA-100 can be controlled via PSA Interactive, a comprehensive graphical user interface and via PowerShell, a powerful script automation environment for all PowerSync Analyzer products. The PSA-100 is optionally capable of running the PSE Conformance Test Suite offering the most comprehensive automated IEEE conformance tests in the industry. The PSA-100 includes a fully automated PoE Service Analyzer to support comprehensive analysis of PoE Service at the outlet to a PD. The dual-port PSE test instrument provides testing capabilities for Power Sourcing Equipment (PSE) including PoE End-Point Switches, Midspan Hubs, Powered Patch Panels, and Integrated Modular Connectors. The module supports 10/100/1000 Mbps Ethernet formats. It has been designed to complement and integrate into existing strategies and tests for Ethernet networking equipment.

PSA Interactive Graphical User Interface The Sifos PSA Interactive Graphical User Interface (GUI) is a flexible and powerful tool designed to allow user quickly to configure and perform both standard and user-defined measurements on IEEE 802.3 compliant power sourcing equipment (PSE). PSA Interactive provides an intuitive view of the full range of testing resources available within the PSA-100 PowerSync Analyzer. Users can quickly harness the flexibility and power of these resources to perform design verification and diagnostic measurements or to prototype sequences that will eventually be automated in PowerShell scripts. PSA Interactive organizes PSA-100 resources and testing features into nine distinct subsystems:

• Port Detection Configuration

• Trigger Configuration

• Load and Load Transient Configuration and Activation

• DC Meters (Average, Max Peak, Min Peak, and Trace Voltage and Current meters)

• AC Voltage Meter

• Time Interval Meter

• PSE Conformance Tests

• PSE Conformance Test Sequencer

• Waveform Viewer

PSA Interactive enables rapid multi-port configurations and one-button testing and analysis through intuitive subsystem dialogs that flexibly address test ports and PSA chassis’.

PowerShell Tcl/Tk Environment

The PowerShell Scripting Environment provides a high level, live-keyboard means to control and program automated test sequences for the PSA-100 Compact PowerSync Analyzer. PowerShell enables fully automated testing suites that span multiple ports, blades, and frames. Built upon the popular Tool Command Language (Tcl), it offers an extensive and extensible programming language. PowerShell provides a complete API for the PSA-100 including high level commands that capture and display graphical waveforms as well as option-enabled commands to execute and sequence standard IEEE 802.3 PSE Conformance Tests. PowerShell commands access all of the resources of the PSA-100 and enable the rapid development of highly customized test scripts. PowerShell fully supports off-line script development and debug through its robust built-in emulation mode. PowerShell libraries can be integrated into broader Tcl environments that interlace traditional network transmission tests with Power-over-Ethernet tests. This enables seamless integration of custom or standard PSE tests with existing Tcl-based test suites. Other features offered by the PowerShell Tcl environment include:

• Interpretive command execution (no compilation, simple debug)

• Simple, intuitive PowerSync Analyzer commands (API)

• Integrated command “help” tools

• Full access to PSA triggering and signal synchronizing features

• Fast test execution speeds

• Script-configured test report files

• Use in tandem with PSA Interactive GUI

• Fully script compatible with PSA-1200 and PSA-2400 Analyzers from Sifos

• AnyEdit Smart Editor for PowerShell

• Traditional Tcl Console or Command-Knowledgeable Wish Console with PSA waveform viewer capability

802.3af PSE Conformance Test Suite (PSA-100-CT) The IEEE 802.3 PSE Conformance Test Suite is a library of fully automated, flexibly sequenced, and self-adapting tests that provide a high degree of specification compliance testing on PSE ports without the need for any external instrumentation. These tests are accessible to both PSA Interactive (GUI) and to PowerShell. The PSE Conformance Test Suite consists of the following modules for testing 802.3af compliant and pre-standard 802.3at High Power PSE’s:

Detection Voltages PSE Power Capacity Detection Current Compliance Short Circuit Compliance Detection Acceptance Range (R and C) Overload Transient Response Detection Timing DC MPS Validity PSE Source Resistance DC MPS Shutdown Classification Voltage AC MPS Shutdown Classification Timing AC MPS Signal Characteristics Power-Up Turn-On and Rise Time Overload Shutdown Power-Up Inrush Compliance Turn-Off Time PSE Voltage and Ripple Turn-Off Voltage PSE Noise PSE Output Capacitance & Shunt Resistance

Each test captures and reports one or more parameters that are directly related to the IEEE 802.3 specification. Under sequencer control, multiple PSE tests can automatically sequence across multiple PSE ports in accordance with user selections.

PowerShell Wish Console



The 802.3 PSE Conformance Test Suite includes several report generation options including automatic Microsoft Excel spreadsheet that reports test results, test statistics, test limits, and pass/fail results on one or more cycles of testing. An example of a PSE Conformance Test Suite test report is shown below:

PoE Service Analyzer Application The PoE Service Analyzer is a special automated test and reporting application to enable comprehensive parametric and interoperability analysis at any PD connection point in a PoE enabled wiring plant. See Sifos Technologies, PoE Service Analyzer Product Overview for further information regarding the PoE Service Analyzer.
