PCIe3 4-port (10 Gb FCoE and 1 GbE) LR and RJ45 adapter (FC EN0M and FC EN0N; CCIN 2CC0)
Learn about the specications and operating system requirements for the feature code (FC) EN0M and FC
EN0N adapters.
Overview
The PCIe3 4-port (10 Gb FCoE and 1 GbE) LR and RJ45 Adapter is a PCI Express (PCIe) generation 3, x8,
adapter. The FC EN0M is a regular-height adapter and the FC EN0N is a low-prole adapter. The adapter
has four-ports and is a Fibre Channel over Ethernet (FCoE) converged network adapter (CNA). This
adapter provides a PCIe 3.0 host bus interface. The adapter is a high-performance adapter that
consolidates trafc for networking and Fibre Channel storage. The adapter is optimized for cloud
computing, virtualization, storage, and other data center applications. Both the FCoE and network
interface controller (NIC) functions are available for all the four ports. Use of the FCoE requires that you
use convergence enhanced Ethernet (CEE) switches. The link aggregation and failover features of the
adapter make it suitable for critical network applications that require redundancy and high availability.
Important: There is no FCoE support on POWER9 systems.
The four-port adapter provides two 10 Gb FCoE Long Range (LR) optical ports and two 1 Gb RJ45
Ethernet ports. The two 10 Gb FCoE ports provide an SFP+ optical transceiver and have little connector
(LC) duplex-type connectors. Each FCoE port provides Ethernet connectivity with a nominal data rate of
10 Gbps (gigabits per second). The optical transceiver uses shortwave laser optics and is attached with
MMF-850nm ber cabling with LC connectors. See Cables
for more information about the optical cables.
An FCoE switch is required to be attached for any FCoE trafc on this adapter.
Each of the 1 Gb ports provides Ethernet connectivity at a data rate of 1 Gbps and is connected with
Ethernet cables. Figure 70 on page 192 shows the FC EN0M adapter.
Restriction: The 1 Gb Ethernet ports do not support data rates of 10 Mbps (megabits per second).
The adapter provides the following features:
• The adapter supports both the dedicated mode and SR-IOV (Single Root I/O Virtualization) mode to
function as a NIC.
• The adapter can function as a boot adapter.
• The adapter supports all Fibre Channel and Ethernet topologies.
• The adapter provides end-to-end data path parity and cyclic redundancy check
