Redundant module for R1S2-5120V0V systems

The KHACHIMO R1S-1120V is a 1+1 redundant power module built for the R1S2-5120V0V platform. It supplies an ATX form-factor unit that fits into a hot-swap chassis bay. The design targets operators who need continuous uptime without shutting down to replace a failed unit.

Tested unit with standard ATX cooling

Each module is test-working before shipment and uses its internal fan for thermal management under normal load. The redundant pairing shares the power draw so neither unit runs at its limit. Acoustic output stays at typical server-room levels. Buyers who need a non-redundant single supply or a different form factor cannot use this module.

Questions about this item

How do I install the R1S-1120V 1+1 redundant module into an R1S2-5120V0V chassis and what step is commonly missed?

Slide the module into the bay until the latch clicks, then secure the retention screw; the step often missed is fastening that screw, which keeps the hot-swap connection firm.

What maintenance will the R1S-1120V 1+1 redundant power module need over time?

Periodically vacuum dust from the intake vents and verify both modules show green status LEDs; replace a module only if its LED turns amber or the system logs a fault.
