OFC offline online originator Point-to-Point port port name POST Power On Self Test (POST) PPP processor protocol O An acronym for Open-Ended Fibre Control. When a cable link is dropped, the laser drops, to eliminate the potential for eye damage. Taking the bridge offline indicates that all SCSI and FC adapters in the bridge are offline. Taking a SCSI adapter offline means ending inputs/outputs and suspending all transactions going from the bridge to the specified SCSI devices. The SCSI adapter is no longer active or available for access. Taking a FC adapter offline means ending inputs/outputs and suspending all transactions going from the 4x50 to the specified FC device. For the bridge, online indicates that at least one adapter in the bridge is active and available for access. For a SCSI adapter, online indicates the SCSI adapter is active and available for access and input/output processing. A Fibre Channel term that refers to the initiating device. P One of three existing FC topologies, in which two ports are directly connected by a link with no fabric, loop, or switching elements present. The FC 2/1 LV and FC 4/1 HV use FC-AL to support Point-to-Point configurations. The hardware entity within a node that performs data communications over the Fibre Channel link. A field value under the FC Status menu; the FC port identifier; a 64-bit value the factory assigns to each FC adapter. See Power On Self Test. A group of tests run when the 4x50 is powered on. An acronym for Point-to-Point Protocol. A transmission path over which data is transmitted between two Fibre Channel devices. Contains the arithmetic and logic, control, and internal memory units that control the bridge. A data transmission convention encompassing timing, control formatting, and data representation. 253
