HPE Aruba 3810M 2QSFP+ 40GbE Module

The HPE Aruba 3810M 2QSFP+ 40GbE Module is a compact expansion card designed to unlock high-speed uplinks for the Aruba 3810M Switch. This expansion module delivers two QSFP+ ports that support 40 Gigabit Ethernet, enabling you to scale your network backbone, accelerate data flows between core and distribution layers, and future-proof your infrastructure. Built to complement ArubaOS-Switch ecosystems, it offers a seamless way to boost bandwidth for data centers, campus networks, and high-density edge deployments while preserving investment in your existing Aruba 3810M platform. Whether you’re consolidating virtualization workloads, accelerating storage traffic, or supporting dense server farms, this module adds reliable 40GbE connectivity with minimal disruption.

• Ultra-fast dual 40GbE QSFP+ ports for scalable uplinks — Each QSFP+ port provides up to 40 Gbps of dedicated bandwidth, enabling high-speed uplinks and flexible aggregation options. When used in tandem, you can achieve substantial aggregate capacity to support bandwidth-intensive applications, virtualization, and large-scale data transfers with low latency and predictable performance.
• Plug-and-play expansion for Aruba 3810M switches — Engineered specifically for the Aruba 3810M, this module installs into the expansion slot with a straightforward, tool-free process. It becomes an integrated part of the switch fabric, offering quick scalability without replacing existing hardware. The design supports hot-swapping in compatible environments to minimize downtime during maintenance windows.
• Optimized for data center, campus, and core networks — Perfect for backbone connections, storage networks, and high-density access layers. The two 40GbE ports enable fast server-to-switch or switch-to-switch communication, supporting dense workloads, large file transfers, and virtualization clusters. This module helps you reduce bottlenecks at aggregation points and improves overall network responsiveness.
• Enhanced reliability and manageability — Built to enterprise-grade standards, the module integrates with ArubaOS-Switch features for policy, QoS, ACLs, VLANs, and monitoring. Management remains consistent across the network, simplifying configuration and troubleshooting while maintaining centralized visibility and control over traffic flows.
• Flexible cabling options and future-proofing — Compatible with a range of 40GbE cabling approaches, including copper DAC and optical transceivers as supported by your Aruba 3810M infrastructure. This flexibility lets you tailor distance and fiber requirements to your environment and keeps you prepared for bandwidth growth without unnecessary rework.

how to install HPE Aruba 3810M 2QSFP+ 40GbE Module

Step 1 — Prepare and decide on downtime (if required): Review your change-control policy. If your environment supports hot-swapping of expansion modules, you may proceed without powering down. If not, schedule a maintenance window to minimize impact and ensure proper safety procedures.

Step 2 — Access the expansion slot: Locate the designated expansion slot on the Aruba 3810M chassis. Remove any covers or panels as needed to expose the slot. Keep the module in its protective packaging until you are ready to install.

Step 3 — Insert the module: Align the module with the slot and insert it straight into the connector until it seats securely. A firm click or lock usually indicates proper engagement. Avoid twisting or applying uneven pressure to prevent damage to the connector.

Step 4 — Reassemble and power on (if required): Replace any panels, reconnect power, and monitor the switch for the module to be recognized. Check the LED indicators on the module and the main switch to confirm a healthy, active state according to your device documentation.

Step 5 — Configure and verify: Use the ArubaOS-Switch management interface or CLI to enable the new ports, set up uplink or aggregation configurations, and apply QoS, VLANs, or ACLs as needed. Validate connectivity by testing throughput to connected devices and verifying link aggregation groups if used. Document the configuration for future maintenance and audits.
