QNAP ES2486AFDC-2142IT-128G - Controller

The QNAP Controller FRU for ES2486dc 2142IT 128GB (No PSU) is a field-replaceable hardware module designed for the ES2486dc-series 2U rack-mount NAS platforms. It fits the dual-controller architecture of these systems, allowing integrators to repair or upgrade a single controller node without replacing the entire NAS. Each unit restores full processing capability to the chassis once installed.

This module is supplied without a power supply and draws power from the host chassis. It connects directly to the chassis backplane and handles the data services and storage protocols supported by the system. The part is intended for qualified data centre operators and system administrators carrying out component-level service. Replacing a single controller with this FRU reduces downtime and preserves hardware redundancy in rack-mount storage operations.
