How to install StarTech.com HPE JL484A Compatible SFP28 Module

• Preparation: Power down the device if required by your equipment’s hot-swap policy, or verify that the slot supports hot-swapping before removal or insertion.
• Locate the SFP28 slot: Identify the appropriate port on your switch, router, or server where an SFP28 transceiver is supported and available.
• Remove existing module (if upgrading): If replacing an existing transceiver, release the latch, gently pull the module straight out, and set it aside.
• Install the new module: Align the StarTech.com SFP28 module with the slot, slide it in firmly until it seats, and engage the latch to secure it in place.
• Connect the fiber cable: Insert a clean LC duplex multimode fiber patch cord into the module’s LC connector, ensuring a snug, secure connection with proper fiber handling.
• Verify link status: Re-enable the port if required and monitor the interface through your network management system to confirm a stable link and expected optical diagnostics values.
