Dell RH820 PowerEdge 860 Control Panel Board

The Dell RH820 (board model DA0S30TH4D6) is the front-panel I/O control board for the PowerEdge 860 and PowerEdge R200 1U rack servers. This board is the hardware intermediary between the physical front-panel controls — power button, reset button, status LEDs — and the server's main board. When this component fails, symptoms include an unresponsive front power button, incorrect or non-functional status LEDs, and in some configurations, inoperative front-panel USB or VGA ports. It is a passive board carrying no firmware, meaning correct installation immediately restores normal front-panel behavior without any software intervention. The DP/N identifier RH820 is the authoritative Dell part number for cross-referencing against a failed unit.

The RH820 is a targeted serviceable replacement for system administrators and IT professionals maintaining PowerEdge 860 or R200 infrastructure past the original hardware support lifecycle. In environments where iDRAC remote management is configured, a failed front panel is operationally tolerable but represents a loss of physical redundancy for out-of-band access. In environments without remote management, a non-functional front-panel power button can render a server unbootable outside of internal jumper procedures. This part is sold in used condition — the correct purchasing context is a repair operation where the existing board is confirmed failed and the DP/N has been verified against the replacement. It is not a platform upgrade or performance component; it is a precision replacement for a discrete, failed hardware element in a known-legacy server platform.
