CBO DAC cable 3 m for Dell Networking 470-AAXG direct-attach copper cable

CBO DAC cable 3 m for Dell Networking 470-AAXG direct-attach copper cable is a 3-meter passive direct-attach copper (DAC) solution designed for short-range, low-latency connections between compatible SFP+ or QSFP ports on Dell Networking equipment and other supported network devices. The cable provides a physical-layer link suited for rack-to-rack or within-chassis interconnections in data centers and enterprise network environments, offering plug-and-play operation without additional transceivers.

Advantages

This direct-attach copper cable delivers low latency and stable physical connectivity with minimal power consumption compared with active optical solutions. Its fixed-length copper construction simplifies installation and reduces component count by eliminating separate transceivers. The cable is optimized for short-reach links, providing predictable performance for aggregated switching, server uplinks, and top-of-rack connections when used with compatible ports.

Suitable for

• Short-range interconnects between racks in data centers
• Chassis-to-chassis connections inside network cabinets
• Server uplinks to switches with compatible SFP+/QSFP ports
• High-throughput, low-latency links in enterprise networks

Key specifications

• Cable type: passive direct-attach copper (DAC)
• Length: 3 meters
• Interface compatibility: SFP+ or QSFP form-factor ports (verify device compatibility)
• Typical use: short-reach, rack-to-rack and in-chassis connections
• Power profile: low power consumption compared to active optical transceivers

How to use

Ensure both network devices support DAC connections on the targeted SFP+ or QSFP ports and verify firmware or vendor compatibility notes before installation. With devices powered down or live-insert compatible, insert each cable end into the corresponding port until it clicks into place. Confirm link status via the device management interface or indicator LEDs and adjust network settings such as speed, duplex, or link aggregation as required by your network design. For removal, depress the release latch and pull the connector straight out to avoid damaging the port.

Recommendations

Use the cable for short-distance, high-bandwidth links within the same rack or between adjacent racks; avoid long cable runs beyond the recommended 3 m. Keep connectors and port areas free of dust and handle the cable by the connector housings to prevent strain. Verify compatibility with your Dell Networking or other vendor equipment to ensure predictable operation.
