How to Install StarTech.com HPE 455886-B21 Compatible SFP+ Module

Follow these steps to install the transceiver quickly and safely in compatible HP devices or other SFP+‑equipped platforms:

• Power down the device or verify your equipment supports hot‑swap before insertion, following your vendor’s service guidelines.
• Hold the SFP+ module by its edges and align it with the SFP+ slot on the switch or router, ensuring the connector is oriented correctly.
• Gently insert the module into the slot until it seats firmly and you hear a subtle click indicating a secure connection.
• Connect a single‑mode fiber patch cable with LC duplex connectors to the module’s LC ports, ensuring the transmit and receive fibers are correctly aligned (Tx to Rx).
• Power up the device (if powered down) and allow time for the interface to come up; the link LED should indicate activity once the link is established.
• Verify link status and 10G throughput through the device’s management interface or CLI; consult your network performance monitoring tools to confirm link quality.
• If the link does not come up, reseat the module, try a known‑good fiber patch cord, or test with an alternate patch to isolate any fiber or port issues.
