AB287A HP PCI-X 1-port 10 Gb Ethernet Fiber Adapter

AB287A is a PCI-X 133 MHz, 64-bit 10 Gigabit Ethernet card with one duplex LC connector for 10GBase-SR multimode fibre. The single port runs only at 10 Gbit/s in full-duplex mode, with no autonegotiation, and it meets IEEE 802.3ae-2002. It does not link to 10GBase-LR, ER, SW, LW or EW ports, or to 1000Base-SX or 100Base-FX.

Reach depends on the fibre: 2 to 26 m on 62.5 micron fibre at 160 MHz*km, 2 to 82 m on 50 micron fibre at 500 MHz*km, and 2 to 300 m on 50 micron fibre at 2000 MHz*km. A link LED and an activity LED sit beside the connector. LC-LC cables with 50/125 micron multimode fibre are C7524A (2 m), AF552A (15 m) and C7526A (50 m).

AB287A operates on 64-bit HP-UX 11i v1 and 11i v2 on HP Integrity and HP 9000 servers. Jumbo frames use an MTU of 9000 bytes, TCP segmentation offload and checksum offload are on by default, and on-board data and control structures are protected by ECC. The HP-UX 11i v2 driver adds receive multi-queue. HP Serviceguard and the LAN_MONITOR mode of Auto-Port Aggregation are supported; the LACP_AUTO, FEC_AUTO and MANUAL modes are not.

Allow 512 MB of memory and one CPU for each AB287A. A dual-rope PCI-X 133 slot provides the best throughput, PCI-X 66 and PCI 33/66 slots also work, and a shared slot needs the other card in PCI-X mode. Platforms with only PCI slots, or only single-rope PCI-X slots, are not supported. Card counts: 1 in the rx1600, rx1620, rx2600 and rx2620, 3 in the rx2660, 4 in the rx3600 and rx6600 with PCI-X slots, 2 in the rx7620 and rx8620, and 4 in the rx7640 and rx8640. Servers that take it include the HP Integrity rx6600 and the HP Integrity rx7620.
