FC-AL Subsystem

Sun Blade 1000 and Sun Blade 2000 workstations support FC-AL (Fibre Channel-
Arbitrated Loop) as the interface for internal and external hard drives. The physical
medium is copper. Optical links are not supported.
The disk drives are connected to the loop through a hub chip. The hub supports two
internal connectors and the external connector. Internal signal detect circuitry
automatically detects the presence of a device at the external connector which
enables or disables the external port. The individual ports can also be bypassed
manually by a software probe and programming a GPIO register in the FC-AL
controller.
