The Extreme Networks 10911 is an EPS-500 external AC power supply, a redundant power unit that connects to a compatible Extreme Networks Summit switch to provide backup power if the switch’s internal supply fails. The EPS-500 sits outside the switch chassis and is used across several Summit-series switch models that support external redundant power, giving network operators a way to add power resilience without swapping the switch itself. Genuine units such as this one are a routine requirement for restoring power redundancy after a failure or adding it to an existing deployment that did not originally specify it. Exact compatibility should be confirmed against the specific Summit switch model before ordering. Tech-Star (UK-based, shipped worldwide) stocks Extreme Networks power hardware to support ongoing network maintenance. Please contact our sales team to confirm compatibility and for current stock and pricing.
