Status indicator Description
Activity
This green status indicator flashes when the disk drive is
being accessed. It is on when the drive is idle.
Online
The green status indicator is on when the disk drive is
online and operating normally. This indicator will be off
in the following situations:
• There is no controller on the bus.
• +5.1 VDC is not available.
• The drive is not properly installed in the enclosure.
Fault
This amber status indicator is on when there is a disk drive
failure. Depending on the host controller, this indicator may
flash when the controller detects an error condition.
The amber status indicator flashes in synchronization with
the other two status indicators in response to the EMU
locate command.
Disk drive status displays
The disk drive status indicators can assume three states: on, off, or flashing. The status indicators states
for operational drive status are shown in Table 9 . See Table 10 for the non-operational drive status
indicator states.
