9.5FC-AL physical interface

Figure 11 shows the location of the J1 Fibre Channel single connection attachment (FC-SCA). Figure 13 pro- vides the dimensions of the FC-SCA connector.

Details of the physical, electrical, and logical characteristics are provided within this section. The operational aspects of Seagate’s Fibre Channel drives are provided in the Fibre Channel Interface Manual..

9.5.1Physical characteristics

This section defines physical interface connector.

9.5.1.1Physical description

FIbre Channel drives may be connected in a loop together or with other compatible FC-AL devices. A maxi- mum of 127 devices may have addresses; however, one of the addresses is reserved for a fabric port switch device. This means 126 addresses are available for FC-AL devices. More FC-AL compatible devices may physically reside on the loop, but they will not be functional because they would not be able to obtain valid addresses.

Port bypass circuits (PBCs) allow devices to be inserted into unpopulated locations or removed from the loop with loop operation recovery after a brief interruption. These PBCs are located external to the FC-AL device. Figure 12 shows the relationship between the PBC and FC-AL device.
