The Expansion Disk Cabinet has 2 UltraSCSI buses. Up to 5 drive units can be installed in the
upper drive bays of the cabinet as shown in the Figure 8.2 below. Internally, they are connected to
an interface board by a single-ended UltraSCSI bus. And, up to 5 drive units can be installed in the
lower drive bays. Also, they are connected to an interface board by a single-ended UltraSCSI bus.
The interface board has a single-ended to differential interface converter in it, and each interface
board is connected to the host server by a differential UltraSCSI bus.
Each interface board has a POWER LED. If a FAULT LED and an ACTIVE LED of a disk bay that
has a disk drive doesn't light up, check the POWER LED on the interface board in the cage if it is
light up or not. A failed unit can be isolated by checking this POWER LED, a ACTIVE LED, a
FAULT LED, and a POWER LED on the power supply unit.
