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.
