HPE 733664-B21 2U CMA server rack for DL380p Gen8

Product Identity

The HPE 733664-B21 is a 2U cable management arm designed for the Easy Install Rail Kit used with the HP ProLiant DL380p Gen8 server. It provides a dedicated pathway to organise and secure cabling at the rear of the rack-mounted chassis. The black metal construction matches the server aesthetics and fits within standard rack environments. This accessory targets administrators deploying or maintaining that specific server model.

Installation Experience

The arm attaches directly to the compatible Easy Install Rail Kit without requiring separate tools or complex fasteners. Its design follows the rail geometry so cables remain routed correctly when the server slides in and out for service. Misalignment can occur if the rail kit itself is not the designated Easy Install version for the DL380p Gen8. Installers should verify the rail model before mounting to avoid fitment issues.

Sustained Operation

Once fitted, the arm holds cables in a fixed radius that accommodates repeated extension and retraction of the server on its rails. The metal arms resist fatigue from continuous vibration in dense rack rows. Cable stress relief is maintained over long duty cycles because the routing path does not rely on plastic clips that can become brittle. The component serves purely as a passive mechanical guide with no active cooling or electronic functions.
