Supersuperuncle MRW-6420P-R 420W Redundant Power Module

SKU CH-9GW8-ZZE8P

420 W redundant power module for EMACS MRW-6420P servers

  • 420W output keeps servers running reliably
  • Redundant module design maintains power during failures
  • Compatible with EMACS MRW-6420P systems
  • New condition ensures full operational life

Compatible Replacement Module

This 420 W redundant power module is built for the EMACS MRW-6420P platform. It slots directly into the existing chassis to restore or expand the power subsystem without rewiring. System integrators maintaining MRW-6420P servers use it to keep the rack online when a primary unit fails or during scheduled maintenance.

Hot-Swap Thermal Design

The unit supports hot-swap insertion so airflow remains uninterrupted while a module is exchanged. Redundant operation shares the load across modules, reducing thermal stress on each supply during normal use. Internal protection circuits guard against over-current and short-circuit events to preserve uptime.

Questions about this item

How do I install the Supersuperuncle MRW-6420P-R 420W redundant power module in an EMACS chassis, and what step is often missed?

Slide the module into the designated hot-swap bay until the latch clicks, then verify the status LED turns solid green; the step often missed is not seating the connector fully, which leaves the module unrecognised by the chassis management controller.

What maintenance or replacement will the MRW-6420P-R 420W module need during its service life?

Expect to clean the intake vents and internal fan assembly periodically to prevent dust build-up; if the fan becomes noisy or the module reports a fault via the chassis management interface, replace the entire 420W unit as it is a non-serviceable FRU.
