Avaya AL1905E01-E5 P-series/Cajun switching and IP Office telephony Power Supply

The Avaya AL1905E01-E5 is a 300W AC redundant power supply for the Ethernet Routing Switch 5600 series, fitting the 5698TFD, 5650TD and 5632FD switch models. It is a hot-swappable field-replaceable unit, and fitting a second matching supply alongside an existing one gives N+1 power redundancy so the switch keeps running if one unit fails. The ERS 5600 series is part of the Nortel enterprise switching range that passed to Avaya with its 2009 acquisition of Nortel’s enterprise networking business, and remains in service across a number of established campus deployments. This is the correct spare for restoring power capacity or redundancy on a compatible ERS 5600-series switch. Specifiers should confirm their exact switch model before ordering, since Avaya’s ERS range used several similarly-numbered power supplies at different wattages. Tech-Star (UK-based, shipped worldwide) supplies refurbished Avaya hardware for engineers maintaining or expanding existing ERS 5600-series deployments.
