HPE 721064-B21 QSFP+ to 4x10G SFP+ DAC Cable
Overview
The HPE 721064-B21 is a 3-meter direct attach copper (DAC) splitter cable designed to break out a single 40 Gigabit Ethernet QSFP+ port into four independent 10 Gigabit Ethernet SFP+ connections. This cable is essential for high-density server racks and network aggregation points where you need to connect multiple 10GbE devices to a single 40GbE uplink port, maximizing port utilization and simplifying cabling. It's a cost-effective, low-power alternative to optical transceivers and fiber for short-reach interconnects within a rack.
Compatibility
This cable is engineered for HPE BladeSystem c-Class infrastructure. It is compatible with HPE switches and network interface cards featuring QSFP+ ports that support 4x10GbE breakout mode. Verify your specific HPE BladeSystem chassis and network modules support QSFP+ to SFP+ breakout configurations for this cable to function as intended.
Installation Notes
This is a passive copper cable, requiring no power input. Ensure the QSFP+ port on your HPE device supports 4x10GbE breakout mode. The SFP+ connectors are keyed for proper orientation. For optimal performance and to prevent damage, insert and remove the connectors carefully, ensuring they are fully seated.
