X3550 M4 2.5" HDD Backplane Adapter

This expansion board adapter card connects four 2.5-inch drive bays to the server backplane. It is designed for administrators upgrading or repairing the storage subsystem of an X3550 M4 server. The kit includes the necessary cables for installation. Builders working on other platforms will need a different part.

Sustained operation in a server chassis

The adapter maintains a stable electrical link between the drives and the backplane during continuous read and write cycles. Cable routing follows the chassis layout to preserve airflow under constant load. No active cooling or thermal management features are present on the board itself. It is not intended for hot-plug scenarios beyond the server's native capability.

Questions about this item

Does the 81Y6657 backplane expansion board generate extra heat when the X3550 M4 server runs continuously?

The board is a passive adapter with no active components, so it adds negligible heat beyond the drives themselves.

Which server chassis and drive bays must I already have to install this 94Y7587 adapter card?

You need an X3550 M4 server with the 4 x 2.5" drive bay cage and the matching backplane power connectors.
