Overview

Top rule

Effective immediately, the technical information for the PCIe3 4-port 10 GbE BASE-T RJ45 adapter (features EN2W and EN2X), as announced in Hardware Announcement 122-084, dated October 11, 2022, has changed.

Existing technical information

PCIe Gen3 short x8 adapter provides four 10 GbE BaseT ports. The ports are RJ45. They default to autonegotiate the highest speed, either 10 Gb (10 GBaseT), 1 Gb (1000 BaseT), or 100 Mb (100 BaseT) full duplex. Each RJ45 port's configuration is independent of the other. The adapter supports Ethernet NIC traffic.

The RJ45 ports use 4-pair CAT-6A cabling for distances of up to 100 meters or CAT-6 cabling for distances up to 37 meters. CAT5 cabling is not tested and is not supported.

Features EN2W and EN2X are electronically identical with the same CCIN 2F04, but they have different tailstock brackets. Feature EN2W has a tailstock for full-height PCIe slots available for Power® E1080, Power E1050, Power S1024, Power S1022, Power S1014, Power S1022s, Power L1024, and Power L1022 servers, and feature EN2X has a short tailstock for low-profile PCIe slots available for Power E1080, Power S1022, Power S1022s, and Power S1022 servers.

Details for the ports include:

  • NIM install supported for VIOS, AIX®, and Linux®
  • IEEE 802.3an (10GBASE-T), IEEE 802.3ab (1000BASE-T GbE), IEEEu (100BASE-T), 802.1p priority, 802.1Q VLAN tagging, 802.3x flow control, 802.3ad load-balancing and failover, link aggregation, IEEE 802.3ad 802.3
  • Multiple media access control (MAC addresses) and promiscuous mode for PowerVM® and VIOS per interface
  • Message Signaled Interrupt (MSI-X, MSI) support of legacy pin interrupts
  • Ether II and IEEE 802.3 encapsulated frames
  • Jumbo frames up to 9.6 KB
  • TCP checksum offload for Internet Protocol (IP) version 4 and IPv6
  • TCP segmentation offload (TSO)
  • Receive Side Scaling (RSS) support for IPv4, IPv6, and User Datagram Protocol (UDP)
  • UDP checksum offload for IPv4 and IPv6
  • AIX, IBM® i, and Linux provide software iSCSI support through the adapter

Revised technical information

The PCIe Gen3 short x8 adapter provides four 10GBASE-T ports. The ports are RJ45, and they default to autonegotiate to the highest speed, which is either 10 Gb (10GBASE-T) or 1 Gb (1000BASE-T) full duplex. Each RJ45 port's configuration is independent of the other. The adapter supports Ethernet NIC traffic.

Supported distances per cable type and connection speed:

  • 10GBASE-T: Distances up to 100 meters using CAT6A or better
  • 1000BASE-T: Distances up to 100 meters using CAT5e, CAT6, or CAT6A

Features EN2W and EN2X are electronically identical with the same CCIN of 2F04. Feature EN2W has a full-high tailstock, and feature EN2X has a low-profile tailstock.

Details for the ports include:

  • NIM install supported for VIOS, AIX, and Linux
  • IEEE 802.3an (10GBASE-T), IEEE 802.3ab (1000BASE-T GbE), IEEE, 802.1p priority, IEEE 802.1Q VLAN tagging, IEEE 802.3x and ab flow control, and IEEE 802.3ad LACP
  • Multiple MAC addresses and promiscuous mode for PowerVM and VIOS per interface
  • Supports MSI-X for load balancing of interrupt handling between multiple cores or CPUs
  • Supports interrupt moderation
  • Ether II and IEEE 802.3 encapsulated frames
  • Supports jumbo frames
  • Supports Link Layer Discovery Protocol (LLDP)
  • TCP checksum offload for IPv4 and IPv6
  • TSO enabled
  • RSS support for IPv4, IPv6, and UDP
  • UDP checksum offload for IPv4 and IPv6
  • Supports firmware updates
  • AIX, IBM i, and Linux provide software iSCSI support through adapter
