Frequently Asked Questions

What is the maximum reach of the HPE Q2F19A QSFP28 SR4 transceiver? +

The HPE Q2F19A is a 100GbE SR4 transceiver optimized for short-reach data center applications. It supports a maximum link distance of up to 100 meters when utilizing OM4 multi-mode fiber optic cabling. This makes it an ideal solution for interconnecting high-density switches within the same rack or across adjacent rows in a standard data center environment.

Which specific HPE networking equipment is compatible with the Q2F19A module? +

The Q2F19A is designed for high-performance HPE switch series that feature 100GbE QSFP28 ports. It is generally compatible with HPE FlexFabric and Aruba switch models that support the QSFP28 form factor. We recommend checking your specific switch model’s QuickSpecs or the HPE compatibility matrix to ensure the firmware version supports this transceiver for your infrastructure.

Does the Q2F19A support breakout configurations for 25GbE connectivity? +

As an SR4 transceiver, the Q2F19A utilizes MPO/MTP connectors to provide four lanes of 25GbE data transmission. In many deployment scenarios, this module can be used with breakout cables to connect a 100GbE QSFP28 port to four individual 25GbE SFP28 ports on downstream devices, offering excellent flexibility for high-density server aggregation in modern leaf-spine architectures.

What type of fiber optic cabling should be used with the HPE Q2F19A? +

This transceiver requires multi-mode fiber (MMF) cabling with MPO/MTP connectors. For optimal performance and to achieve the maximum specified 100-meter range, we recommend using laser-optimized OM4 fiber. Using high-quality, clean fiber patches is essential to maintain low insertion loss and ensure the integrity of the 100Gbps signal across the link.

What are the primary advantages of using QSFP28 SR4 modules in a data center? +

QSFP28 SR4 modules provide a compact, high-density solution for 100GbE connectivity. By utilizing parallel optics, these modules minimize power consumption and reduce the physical footprint on your switch faceplate compared to older, bulkier standards. They are specifically engineered to provide reliable, low-latency performance required for compute-intensive workloads and high-speed storage area networks.

How does the power consumption of the Q2F19A impact switch thermal management? +

The Q2F19A is designed to operate within the standard power envelope defined for QSFP28 modules. By maintaining efficient power profiles, these transceivers help keep the overall thermal output of the switch within manageable limits. Proper airflow and cooling within your rack are still necessary when populating a switch with multiple high-speed transceivers to ensure peak hardware longevity.

Is the Q2F19A module hot-swappable during normal switch operation? +

Yes, the Q2F19A is designed to be hot-swappable, allowing you to install or replace the module without needing to power down the host switch or disrupt other active network ports. This feature is critical for maintaining uptime during network upgrades or when replacing a faulty unit, as it allows for immediate, seamless integration into your existing production environment.

What indicators should I look for to ensure the Q2F19A is installed correctly? +

Proper installation is confirmed when the module is fully seated into the QSFP28 cage until you hear a click. Once connected to a powered switch, the corresponding link status LED on the switch port should illuminate or transition to green. You can further verify the connection via the switch's CLI by checking the transceiver status and optical power levels.

Can I request a bulk quote for multiple Q2F19A units from BuyRouterSwitch.com? +
