The AB378A is a single-port 4 Gb-capable adapter that operates in PCI 33 MHz/66 MHz and PCI-X 66 MHz/133 MHz/266 MHz bus speeds with a 64-bit bus width. The port supports Auto-Speed Negotiation and is capable of 1 Gb, 2 Gb, or 4 Gb data transfer rates. Auto-Speed Negotiation enables each port on the adapter to automatically negotiate the highest speed common to the port and the infrastructure connecting the port. Use the fcmsutil diagnostic tool to display link speed and other Vital Product Data (VPD) information.

The AB378A single port adapter supports Online Addition and Replacement (OLAR) on OLAR-capable systems running HP-UX 11i v1 or 11i v2. OLAR refers to the ability of a PCI card to be replaced (removed or added) without shutting down and rebooting the system.

The AB378A single port adapter supports fabric topologies. The direct attach topology is supported using arbitrated loop topology.
