PCIe3 4-port 10 GbE SR Adapter (FC EN15 and FC EN16; CCIN 2CE3)
Learn about the specifications and operating system requirements for the feature code (FC) EN15 and
EN16 adapter.
Overview
The FC EN15 and EN16 are the same adapter. FC EN15 is a full-height adapter, and FC EN16 is a low-
profile adapter. The names of these two adapters are:
• FC EN15: PCIe3 4-port 10 GbE SR Adapter
• FC EN16: PCIe3 LPX 4-port 10 GbE SR Adapter
The PCIe3 4-port 10 GbE SR Adapter is a PCI Express (PCIe) generation 3, x8, short form-factor adapter.
The adapter provides four 10 Gb small form-factor pluggable (SFP+) optical SR transceiver ports, as
shown in Figure 78 on page 208. The ports have little connector (LC) duplex-type connectors and utilize
shortwave laser optics and MMF-850nm fiber cabling. See “Cables” on page 209 for more information
about the optical cables. The adapter supports the Ethernet network interface controller (NIC) function
and also provides SR-IOV NIC support. SR-IOV capability for the NIC function is supported with the
appropriate firmware and operating system level for any of the four ports. Enabling the SR-IOV function
requires an HMC.
The adapter provides the following features:
• Four 10 Gb ports that can function in the NIC mode
• AIX Network Installation Management (NIM) support
• The adapter supports interrupt moderation to deliver increased performance while significantly
reducing processor utilization
• The adapter supports multiple media-access control (MAC) per interface.
• The adapter supports integrated media-access control (MAC) and physical layer (PHY).
• The adapter supports the following standards for the different ports and functions:
– IEEE 802.3ae in the 10 GbE ports
– 802.3ab in the 1 GbE ports
– Ether II and IEEE 802.3 for encapsulated frames
– 802.1p for setting up priority levels in tagged VLAN frames
– 802.1Q for VLAN tagging
– 802.3x for flow control
– 802.3ad for load-balancing and failover
– IEEE 802.3ad and 802.3 for link aggregation
• The adapter provides message signal interrupts (MSI), MSI-X, and support of legacy pin interrupts.
• The adapter supports jumbo frames up to 9.6 KB.
• The adapter supports TCP checksum offload transmission control protocol (TCP), user datagram
protocol (UDP), TCP segmentation Offload (TSO) for IPv4 and IPv6.
• Supports TCP segmentation or large send offload
• Supports EEPROM-SPI and single EEPROM
• Compliant with European Union Directive 2002/95/EC on the Restriction of the Use of Certain
Hazardous Substances in Electrical and Electronic Equipment
