HPE 684216-B21
FlexFabric 361FLB 1 GbE 2‑Port FlexibleLOM Adapter Card
The HPE 684216‑001 (361FLB) is a FlexibleLOM mezzanine network Adapter Card tailored for HPE ProLiant c-Class Gen8 blade servers. It provides two 1 Gbps Ethernet ports (10/100/1000Base‑T via RJ‑45) using Intel I350 controller over a PCIe x4 interface, offering reliable connectivity in converged server environments. Designed as a cost-effective FlexFabric Adapter Card , it supports later upgrades to 10 GbE without changing form factor, helping protect initial infrastructure investments. With low power consumption (~2.8 W) and OEM optimization for blade chassis backplane, it enables efficient network performance and remote management integration in legacy blade system environments
Features
This dual-port 361FLB Adapter Card is based on the Intel I350 controller and connects via PCI Express 2.1 ×4 mezzanine slot inside supported Gen8 c-Class blade servers. It delivers full 1 Gb/s per port with support for auto-negotiation at 10/100/1000Base‑T. Designed for internal chassis integration, it offers enterprise-grade link resilience with support for Wake-on-LAN, PXE boot, VLAN tagging, and robust driver support under HPE system management framework. Compatible with blades such as BL460c Gen8, BL420c Gen8, BL660c Gen8, and aligns with HPE virtualization-friendly network fabric architecture.
Advanced Options
Refurbished versions of the Adapter Card typically ship with ~90-day warranties from trusted resellers, while OEM-new units provide standard HPE warranty support and service coverage. Its mezzanine form factor supports low-profile installation, minimal chassis footprint, and passive cooling via server backplane. Although not a FlexFabric‑capable Adapter Card like newer Gen9/10 models, the 361FLB remains effective for baseline networking in Gen8 legacy deployments and offers upgrade flexibility.

Reliability & Performance
Built for long-term reliability within HPEc-Class blade chassis, the 361FLB adapter delivers consistent and predictable 1 GbE performance under load. The Intel I350 chipset ensures stable operation with minimal CPU overhead, while its low (<3 W) power consumption contributes to efficient chassis thermal design. Hardware support for functions like PXE boot and Wake-on-LAN enables remote provisioning and management in data center environments. OEM certification ensures seamless integration with HPE server management tools and firmware upgrades. The mezzanine design preserves rack blade slot space and simplifies installation and replacement. For operators using Gen8 blade systems, this adapter delivers a balance of functionality, low operational cost, and upgrade path for future 10 GbE needs. Refurbished units are cost-effective for less critical paths, while OEM-new units retain full support and lifecycle firmware access.
