How to install StarTech.com HPE 720187-B21 Compatible QSFP+ Module

• Power down the device and disconnect all cables before handling the transceiver to prevent electrostatic discharge and equipment damage.
• Identify an available QSFP+ port in the switch, router, or server network equipment that supports 40GBASE-SR4 transceivers and is compatible with HPE 720187-B21 form-factor modules.
• Gently align the QSFP+ module with the slot and slide it in until the latches engage securely. A proper click or latch engagement indicates the module is seated correctly.
• Connect the fiber cable to the MPO/MTP connector on the module using a clean, properly terminated OM3 or OM4 MMF cable. Ensure the connector is fully seated and that the fiber ends are free of dust and debris.
• Power on the equipment and verify link status through the device’s management interface or status LEDs. Confirm that the 40G link is established and that traffic flows as expected. If issues arise, reseat the module or re-terminate the fiber optics and recheck the configuration settings.
