Page 5: Introduction
Section 3 will review basic PoE technology, PSE product characteristics, and the hardware/software features of the PowerSync Analyzer. The PowerSync Analyzer family from Sifos Technologies also includes the following products: PSA-3000: Chassis-based analyzer with capacity to test up to 24 PSE ports. The PSA-3000 fully supports optional modules including the 802.3at PSE Conformance Test Suite and the PSE Multi-Port Suite. -

PSA_Installer_#.#.#.exe ForceTCLInstall=1 Sifos Technologies has determined that certain CAD software packages in the market will install proprietary versions of Tcl/Tk that are not compatible with PSA software. If conflicts arise with the Tcl/Tk installation, the above command line installation procedure should be attempted. If that does not resolve the issue, contact Sifos Support for further guidance. - Page 10 PowerSync Service Analyzer Reference Manual June 12, 2017 Sifos Technologies page...
