Keep MediaPack 5xx voice infrastructure available with a dedicated 48V DC replacement power supply. The AudioCodes FRU/MP5XX/DC48VPS is a spare part designed for environments where gateway uptime matters and service continuity cannot wait for a full hardware replacement. For operations teams, a field-replaceable power supply shortens recovery time and helps preserve the value of installed gateway hardware. For procurement, it is a practical service item that supports lifecycle management without forcing a larger capital purchase. That matters in telephony environments where a single failed component can interrupt analog-to-IP connectivity and create avoidable service tickets. This part is intended for MediaPack 5xx deployments that require a compatible 48V DC supply. It is the kind of component that belongs in a disciplined spares strategy: small enough to stock, specific enough to matter, and essential when a production gateway needs to return to service quickly.
