Ruckus RPS21-E 400W Hot-Plug Redundant Power Supply

RUCKUS RPS21-E - 400 W Hot-Swappable AC Power Supply Module

Overview

The RUCKUS RPS21-E is a 400 W AC power supply module designed for enterprise-class access switches, particularly the ICX series from RUCKUS. It is intended for hot-plug or redundant power roles in switch chassis or fixed chassis models that support dual power supplies. With this module installed, network engineers deploying large access fabrics×such as campus aggregation switches or high-density wiring-closet switches×can ensure that the power subsystem matches the throughput and resilience requirements of the network. For example, in a 24-port or 48-port 1 Gb access switch stack, the RPS21-E gives you a full 400 W of output, enabling the switch to power its internal modules and offer room for future growth without replacing the PSU. Because it is hot-swappable, you can insert or replace the unit without shutting down the entire switch, which is critical in environments that cannot tolerate downtime (such as data-centers or campus core switches). Whether you are building out resilient access layers or planning for stacking performance with redundancy, the RPS21-E is a practical power-module choice that aligns with enterprise deployment standards.
