Mapping Table
A table which is indexed by sequential LUN values, indicating selected
BUS:TARGET:LUN devices. It is used by the PSFR-CP41 to perform Fibre
Channel-to-SCSI operations by default.
MIB

Multiplexer
A device that allows two or more signals to be transmitted simultaneously on
a single channel.
Motherboard
The main PCA of the PSFR-CP41 that provides a physical and logical
connection between Fibre Channel and SCSI devices.
N_Port
A FC term defining a ”Node” port. A FC-defined hardware entity that
performs data communication over the FC link. It is identifiable by a unique
Worldwide Name. It can act as an originator or a responder.
N_Port Identifier
A FC term indicating a unique address identifier by which an N_Port is
uniquely known. It consists of a Domain (most significant byte), an Area, and
a Port, each 1 byte long. The N_Port identifier is used in the Source Identifier
(S_ID) and Destination Identifier (D_ID) fields of a FC frame.
Node Name
A field value under the FC Status Menu. The unique FC identifier, a 64-bit
value, the factory assigns to the PSFR-CP41.
Offline
Taking the PSFR-CP41 offline indicates that all SCSI and FC adapters in the
PSFR-CP41 are offline.
Taking a SCSI adapter offline means ending inputs/outputs and suspending
all transactions going from the PSFR-CP41 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The SCSI adapter is no longer active or available for access.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 PSFR-CP41 to the specified FC device.
