Juniper EX-PWR-190-DC EX-series Ethernet switches Power Supply

The Juniper EX-PWR-190-DC is a DC power supply field-replaceable unit (FRU) supplying power to Juniper EX-series Ethernet switches. As a hot-swappable FRU, it allows operators to service, replace or add power redundancy without taking the host chassis fully offline, and is one of several power-tier options Juniper offers for this platform family to match a site’s available AC/DC feed and load requirements. Correct power-FRU selection matters for redundancy planning, since chassis of this type are frequently deployed with dual power-supply configurations for N+1 resilience in production networks. Tech-Star (UK-based, shipped worldwide) supplies this Juniper power FRU as used/refurbished stock for engineers maintaining existing Juniper deployments.
