How to install HPE StoreFabric B-Series 100GbE QSFP28 SR4 Transceiver

  • Power down or prepare for hot-swapping if your platform supports it, and verify that the target port is labeled for 100 Gb/s operation. Review your device’s maintenance guidelines before proceeding.
  • Handle the transceiver by the body to avoid touching the optical connectors or contacts. Ground yourself with proper ESD protection to prevent static damage.
  • Remove the existing module from the QSFP28 slot if upgrading, or prepare an empty slot for installation. Align the module with the slot orientation and slide it in firmly until it seats and the retention latch engages.
  • Route the fiber harness correctly and connect the MPO/MTP cable to the transceiver’s connector. Use appropriate polarity and lane mapping as dictated by your network design (check switch port documentation for any required A-to-B or A-to-A configurations).
  • After installation, power on the device (or restore power if you performed a hot-swap) and verify link status using your switch management interface. Confirm that the 100 Gb/s link comes up on all four lanes and monitor for any errors or alignment issues. Run basic loopback tests if needed to validate end-to-end connectivity.

Frequently asked questions

  • Q: What is 100GbE SR4? A: 100GbE SR4 is a short-reach, multi-lane optical transceiver standard that uses four 25 Gb/s lanes on a QSFP28 module to deliver 100 Gbps of data rate over multimode fiber, typically for datacenter interconnects within a few hundred meters.
  • Q: Is this transceiver compatible with non-HPE hardware? A: While it is engineered for HPE StoreFabric ecosystems, SR4 QSFP28 transceivers generally conform to IEEE 802.3 100GBASE-SR4 and may work with other vendors’ switches that fully support SR4 optics; however, cross-vendor interoperability can vary by firmware and platform. Always confirm compatibility with your specific hardware.
  • Q: What fiber cables and connectors do I need? A: Use multimode fiber (OM3 or OM4) with MPO/MTP connectors to connect the SR4 transceiver. The exact length and fiber grade should align with your distance requirements and installation environment.
  • Q: Can I hot-swap this transceiver? A: Yes. The HPE StoreFabric B-Series 100GbE QSFP28 SR4 transceiver is designed for hot-swapping in supported systems, enabling minimal downtime during maintenance and upgrades. Follow standard ESD guidelines and platform-specific procedures.
  • Q: What should I do if the link doesn’t come up? A: First, verify physical connections and fiber polarity. Ensure the module is properly seated and recognized by the system firmware, and confirm the switch port is configured for 100G operation. Check for lens cleanliness, ensure correct lane mapping, and review event logs or interface counters for errors related to NRZ, lane alignment, or signal integrity.
