node An FC device that contains an N_Port or NL_Port. non-participating A mode in which an L_Port in a loop is inactive and cannot arbitrate or send frames, mode but can retransmit any received transmissions. This mode is entered if there are more than 127 devices in a loop and an AL_PA cannot be acquired. See alsoL_Port, AL_PA. Nx_Port A node port that can operate as an N_Port or NL_Port. Onboard The HP BladeSystem Onboard Administrator (OA) is the enclosure management Administrator (OA) processor, subsystem, and firmware base used to support the HP BladeSystem c7000 and all the managed devices contained within the enclosure. packet A set of information transmitted across a network. participating mode A mode in which an L_Port in a loop has a valid AL_PA and can arbitrate, send frames, and retransmit received transmissions. path selection The selection of a transmission path through the fabric. HP switches use the FSPF protocol for transmission path selection. phantom address An AL_PA value assigned to a device that is not physically in the loop. Also known as phantom AL_PA. See also AL_PA,phantom device. phantom device A device that is not physically in an arbitrated loop but is logically included through the use of a phantom address. See also phantom address. PLOGI Port login. The port-to-port login process by which initiators establish sessions with targets. See also FLOGI. point-to-point An FC topology that employs direct links between each pair of communicating entities. See also buffer-to-buffer flow control. port cage The metal casing extending out of the FC port on the switch and into which a GBIC or SFP transceiver can be inserted. Port_Name The unique identifier assigned to an FC port. It is communicated during login and port discovery. POST Power-on self-test. A series of diagnostic tests run by a switch after it is powered on. primary FCS switch Primary Fabric Configuration Server switch. The switch that actively manages the configuration and security parameters for all switches in the fabric. private loop An arbitrated loop that does not include a participating FL_Port. private NL_Port An NL_Port that communicates only with other private NL_Ports in the same loop and does not log in to the fabric. public device A device that supports arbitrated loop protocol, can interpret 8-bit addresses, and can log in to the fabric. See also arbitrated loop. public loop An arbitrated loop that includes a participating FL_Port and may contain both public and private NL_Ports. See also arbitrated loop. public NL_Port An NL_Port that logs in to the fabric, can function within a public or private loop, and can communicate with private or public NL_Ports. See also private loop. quad A group of four adjacent ports that share a common pool of frame buffers. Cisco MDS 9124e Fabric Switch for HP c-Class BladeSystem 61
