Dell PowerEdge 2U Sliding Cable Management Arm CMA (770-BDSK)

The Dell PowerEdge 2U Sliding Cable Management Arm (CMA) (Dell Part Numbers: 3CP89 / 03CP89 / Dell Ordering SKU: 770-BDSK) is an essential rack organization accessory engineered to manage and route power, networking, and data cabling behind 2U Dell PowerEdge servers. Designed specifically to pair with standard sliding ReadyRails kits, this flexible arm attachment allows servers to extend fully out of the rack cabinet for servicing without disconnecting or stressing rear cable connections.

Constructed from heavy-duty steel and durable molded channels, the 3CP89 CMA eliminates cable clutter, prevents server rack snags, and maintains clean air pathways behind dense server enclosures. By securing cable bundles along articulated extension arms, it minimizes strain on physical server ports and power supplies while protecting critical network and power cabling from accidental disconnections during routine hardware maintenance.

Available from DataDive, your trusted Server Parts Supplier in Qatar, this original Dell 2U cable management arm is available in our Rack & Infra collection, ideal for organizing server rack enclosures, protecting rear cabling during hot-swap maintenance, improving thermal exhaust airflow, and completing professional server installations across 2U Dell PowerEdge platforms.
