Serial-port iLO/M.2 enablement kit

This HPE P65741-B21 accessory adds a serial port and iLO/M.2 enablement to the ProLiant ML30 Gen11 server. It is designed for administrators who need legacy console access and dedicated management storage on this specific platform. The kit integrates directly into the server chassis without external cabling. It suits IT teams standardising on Gen11 hardware.

Enablement type changes management options

The enablement function activates the iLO/M.2 slot and provides a physical serial interface for out-of-band control. This allows remote firmware updates, hardware monitoring and OS deployment without a connected display or keyboard. The serial connection also supports legacy automation scripts that require a COM port. No additional software licences are included.

Fits ML30 Gen11 only; other servers unsupported

The accessory is validated for the ML30 Gen11 and does not install in earlier ProLiant models or other HPE lines. It provides one serial port and one M.2 enablement path; builders needing multiple serial interfaces or additional M.2 drives must look elsewhere. Capacity is limited to the single enabled slot and port.

Questions about this item

Will the serial-port bracket or the M.2 enablement module need replacement during the server's life?

The P65741-B21 is a passive enablement kit with no moving parts or batteries, so it does not require scheduled replacement.

What limits continuous operation first — thermal headroom of the M.2 slot or the serial port's UART throughput?

The serial port is a standard low-speed UART, so its throughput ceiling is reached long before any thermal limit on the M.2 interface.

How much extra power draw and fan noise does the kit add when the server runs 24/7?

The kit draws negligible power and adds no active cooling, so it does not increase fan speed or audible noise.
