The Dell Broadcom 57840S (JNK9N) is a quad-port 10GbE blade Network Daughter Card designed exclusively for Dell PowerEdge blade servers. As an internal component, it connects directly to the server backplane and interfaces with chassis-integrated switches or pass-through modules. Its SFP+ connectivity enables high-speed internal network links without using external PCIe slots.
This adapter is ideal for dense server environments such as Dell M620, M630, M830, FC630, and FC830. It provides high-throughput internal networking for virtualization, storage access, and clustered computing—while enabling load balancing, VLAN tagging, and failover through server-side configuration.
