SFP-module HP Enterprise J9731A-RFB 10GbE 2-poorts

HP Enterprise J9731A-RFB 10GbE 2-Port SFP module is a compact dual-port 10 Gigabit Ethernet transceiver designed for compatible HPE networking equipment. The J9731A-RFB delivers two SFP+ interfaces in a single module, enabling high-bandwidth uplinks and server connections where increased port density and small form factor are required. This module is intended for use in supported HP Enterprise switches and routers and is identified by MPN J9731A-RFB and EAN 5706998984944.

Advantages

The SFP Module HP Enterprise J9731A-RFB 10GbE 2-Port offers dual 10GbE connectivity in an SFP-compatible form factor, allowing flexible deployment in chassis and fixed switches that accept SFP+ transceivers. Its compact design helps maximize port density while keeping power consumption and heat generation appropriate for rack-mounted and data center environments. Using a vendor-compatible transceiver simplifies inventory and replacement processes for HPE-based networks.

Suitable for

• High-bandwidth uplinks between switches and aggregation layers
• Server-to-switch connections requiring 10 Gigabit Ethernet
• Data center and enterprise network environments with limited port space
• Network upgrades where compact SFP+ transceivers are preferred

How to use

Install the J9731A-RFB module into a compatible HPE switch or router SFP+ slot following the equipment manufacturer’s installation instructions. Insert compatible SFP+ optical or DAC cables into each port to connect to other network devices. Verify module recognition and link status via the device management interface or CLI, and configure network settings such as speed, duplex, and VLANs as required by your network design. For safety, perform installations with equipment powered down if recommended by the switch documentation.

Recommendations

Use HP Enterprise certified or vendor-compatible SFP+ cables and transceivers to ensure interoperability with HPE hardware. Confirm compatibility of the J9731A-RFB with your specific switch model and firmware version prior to deployment. Monitor link status and module temperature during initial operation and include the module in routine inventory and lifecycle management to maintain predictable network performance.
