2.3 Operator Controls and Indicators
Four front-panel LEDs light to give you at-a-glance status information
about the operation of the Extender (see Figure 2-3.).
POWER—
This lights when AC power is connected and switched-on to
the unit.
LINK ACTIVE—
This LED lights when two SCSI Fiber Optic Extenders
are powered up and connected to one another via fiberoptic cable.
BUS ACTIVE—
This LED provides a visual indication of the SCSI
interface BUSY signal. It is a general indication that devices are
communicating via the SCSI bus.
LINK ERROR—

The SCSI Fiber Optic Extender will disconnect from the SCSI bus when
a Link Error is detected.
