Technical Purpose and Design

The ​​CBL-G5GPU-C240M7=​​ is a ​​Cisco-certified GPU power cable​​ engineered specifically for the ​​UCS C240 M7 rack server​​. It provides dedicated power connectivity between the server’s power supply and high-performance GPUs, such as NVIDIA A100 or AMD Instinct accelerators, ensuring stable operation for AI, machine learning, and HPC workloads.

• ​​High-Wattage Support​​: Delivers up to ​​300W per GPU​​, meeting the demands of modern accelerators.
• ​​Cisco UCS C240 M7 Compatibility​​: Tailored pinout design ensures seamless integration with the server’s internal power distribution board.
• ​​Dual 8-Pin PCIe Connectors​​: Secures stable power delivery, minimizing voltage drops during peak loads.

Key User Questions Answered

“Which GPUs are compatible with this cable?”

The CBL-G5GPU-C240M7= supports ​​NVIDIA A100, H100​​, and ​​AMD MI250X​​ GPUs, provided they are installed in the UCS C240 M7’s GPU sleds. Always verify Cisco’s compatibility matrix for firmware-specific requirements.

“Can I use third-party cables instead?”

​​Not recommended.​​ Non-Cisco cables may lack precise voltage regulation or shielding, risking GPU throttling or hardware damage under sustained loads.

“How many cables are needed per GPU?”

One CBL-G5GPU-C240M7= cable ​​per GPU​​ is required. The UCS C240 M7 supports up to ​​4 GPUs​​, necessitating four cables for full configuration.

Where to Purchase Genuine CBL-G5GPU-C240M7= Cables

For guaranteed performance and warranty coverage, source directly from authorized partners like ​​itmall.sale​​. Counterfeit cables often fail under thermal stress, risking costly downtime.
