HPE JH234A

Overview

The HPE JH234A is a 1 meter direct attach copper cable designed to provide 40 gigabit per second connectivity between devices with QSFP+ ports. It enables high-speed links without the need for separate transceivers, making it a practical choice for connecting switches, server adapters, or storage targets in close proximity. Its copper construction helps maintain low latency and reduces power consumption compared to optical cables, which benefits rack environments by lowering heat output and operating costs.

Key features

• Direct attach copper design eliminates the need for additional transceivers, simplifying setup and reducing costs.
• Compatible with HPE Aruba switches such as the 2930M access and CX 8360 core series, ensuring seamless integration.
• Ideal for switch stacking, short uplinks, and top of rack configurations where space and cable management are important.
• Low latency connection supports fast data transfer and responsive network performance.
• Reduced power draw compared to optical alternatives helps maintain cooler rack environments and lowers energy expenses.
• Durable build quality and a weight of approximately 0.41 kg keep the cable stable and secure once installed.
• Compact 1 meter length allows for neat routing without excess slack, improving airflow and organization.

Key specs

• Length: 1 meter
• Connector type: QSFP+ to QSFP+
• Data rate: 40 Gbps
• Weight: approximately 0.41 kg
• Physical dimensions: 28.45 x 32.77 x 3.56 cm

Connectivity and compatibility

This cable is designed to connect devices equipped with QSFP+ ports, commonly found on high-performance HPE Aruba switches and server adapters. It supports direct 40G links without requiring separate transceivers, which simplifies network design and reduces hardware requirements. The cable works well in environments where devices are located close together, such as within the same rack or adjacent racks.

Ideal uses and environments

The HPE JH234A fits well in data centers and enterprise networks where short-distance, high-speed connections are needed. It is particularly useful for switch stacking and top of rack uplinks, where cable length and management are critical. Its low latency and power efficiency make it a strong choice for setups that prioritize performance and energy savings. Network administrators who require quick deployment and reliable 40G links will find this cable a practical and cost-effective solution.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
