HPE 733664-B21 – 2U Cable Management Arm
Overview
HPE 733664-B21 is a 2U cable management arm (CMA) designed for HPE ProLiant rack server rail kits. It is used to organize and route server cables during rack installation and sliding maintenance operations.
It is deployed in enterprise data centers where structured cabling is required to maintain airflow, reduce strain on connectors, and support serviceability of rack-mounted servers. The CMA ensures cables move safely when servers are extended from the rack.
It is used with HPE Easy Install rail kits in compatible 2U ProLiant systems such as DL380-class servers and related platforms depending on rack configuration. Installation is tool-assisted and typically done during rack deployment.
Typical Deployment Scenarios
- Rack server cable management in data centers
- HPE DL380/DL360 rail kit deployments
- Structured cabling for serviceable server racks
- Enterprise infrastructure maintenance setups
