Frequently asked questions

Is this StarTech module compatible with HP/HPE switches and routers?

Yes. This module is designed as a compatible replacement for HP/HPE devices that require the 747698-B21 form factor, providing reliable 40GbE SR4 connectivity in supported HP networking environments.

What does 40GBASE-SR4 mean for my network?

40GBASE-SR4 denotes a short‑reach 40 Gigabit Ethernet transceiver that uses four 10G lanes over multi‑mode fiber. It is well-suited for data center interconnects, connecting servers, top-of-rack switches, and aggregation devices within a typical 400-meter range on OM3/OM4 fiber installations.

What fiber type and connectors does this module require?

The module operates on multi‑mode fiber (OM3/OM4) and uses an MPO/MTP 12‑fiber interface to carry the four 10G lanes that comprise the SR4 standard. Ensure your fiber harness and connectors are compatible with this interface to achieve optimal performance.

Can I hot-swap this transceiver?

In many HP/HPE environments, QSFP+ modules are designed for hot swapping. Always follow your equipment vendor’s procedures for ESD safety and power management when inserting or removing the module to prevent damage to hardware or data.

How do I verify performance after installation?

After installation, use the device’s management interface or CLI to verify link status, duplex settings, and error counters. Run basic traffic tests or use throughput tools to confirm that the 40Gbps lane aggregation and SR4 signaling are functioning correctly across the intended distance.
