Description

STK-RPS-150PS: Product Overview
The ENTERASYS STK-RPS-150PS is an external Redundant Power Supply (RPS) unit designed to provide power backup for compatible Enterasys network switches. This device functions as a centralized redundancy solution, allowing multiple switches to share a common backup power source instead of each switch requiring an internal redundant power supply. The RPS connects to supported switches via a dedicated redundant power port and cable, continuously monitoring the primary power supply of each connected switch. If it detects a failure in a switch’s internal power supply, the RPS instantly takes over to provide uninterrupted power, preventing network downtime.
The unit is engineered for high availability environments where network uptime is critical. It features hot-swappable power modules and fans, enabling maintenance and component replacement without shutting down the connected switches. The STK-RPS-150PS typically supports multiple switches simultaneously, making it a cost-effective redundancy solution for wiring closets and network deployments where multiple switches require power protection. Its design focuses on reliability and serviceability, with status indicators providing clear visual feedback on the unit’s operational state and any fault conditions.

Core Features & Customer Value
The primary value of the STK-RPS-150PS is its cost-effective redundancy​ for multiple network switches. Instead of purchasing an internal redundant power supply for each switch, organizations can protect several switches with a single RPS unit, significantly reducing hardware costs. This is particularly valuable in wiring closet deployments where multiple access layer switches require high availability but individual internal redundancy would be prohibitively expensive.
The hot-swappable design​ ensures that maintenance can be performed without network disruption. If the RPS unit itself requires service or if a power module fails, it can be replaced while the connected switches continue operating from their internal power supplies. The clear status indicators enable quick fault identification, reducing mean time to repair (MTTR) during power-related issues. For network administrators, this translates to improved network reliability and reduced downtime.
Typical Applications
In enterprise network wiring closets, the STK-RPS-150PS provides power redundancy for multiple access layer switches that connect end-user devices. This ensures continuous network connectivity even if a switch’s power supply fails.
In retail environments, the RPS unit protects point-of-sale (POS) system switches, ensuring that payment systems remain operational during power supply failures.
In educational institutions, it provides backup power for classroom and laboratory network switches, maintaining network availability for teaching and learning activities.
