Nortel NTYS05AFE6 Avaya P-series/Cajun switching and IP Office telephony Power Supply

The Avaya Nortel NTYS05AFE6 is a 1140E IP deskphone in graphite finish with icon keycaps, supplied without a power supply unit (RoHS-compliant version). The 1140E is a mid-range IP deskphone from the Nortel/Avaya unified communications range, supporting the standard 1100-series feature set including a backlit display and support for expansion modules on some deployments. Since this unit ships without a PSU, it is intended either for Power over Ethernet deployments or for reuse with an existing compatible power supply already in service. This is the correct spare for restoring or expanding an existing 1140E deployment. Specifiers should confirm their required keycap style (icon vs text) and whether a PSU is separately needed before ordering. This carries Nortel enterprise numbering (NTYS-prefix); Avaya acquired Nortel’s enterprise networking business in 2009, and the wider networking portfolio later moved to Extreme Networks in 2017. Tech-Star (UK-based, shipped worldwide) sources and tests refurbished Avaya and Nortel-lineage hardware like this one to keep 1100-series deskphone deployments running past end of manufacturer support.
