Rear panel (ODS-D77F)
a Drive unit indicator
Indicate the status of the drive units. From the top, the
three indicators are as follows.
• POWER indicator
Lit green: Power is being supplied.
• LINK indicator
Blinking blue slowly (once per second): FC cable is not
connected.
Lit blue: FC cable is connected.
Blinking blue rapidly (four times per second): FC cable
is connected and a command is being received.
Notes
• This indicator is lit blue when the FC cable is
physically connected correctly. It is lit blue while the
FC cable is connected, even when in states where the
drive unit cannot be controlled from a computer.
• This indicator is lit blue during drive unit initialization
after power is applied, even if an FC cable is not
connected. In this case, the indicator starts blinking
blue slowly after initialization is finished.
• STATUS indicator
Lit green: The drive unit can be replaced (i.e., drive is
offline and drive power is off).
Lit red:
• An alarm occurred (alarm code other than 00-000).
• Library and drive units are not communicating
normally.
• The drive unit power supply was forcibly turned off
(POWER indicator also turned off) due to a library
power supply fan fault.
Slow blinking green (1-sec. interval): The drive is
initializing.
Rapid blinking green (0.25-sec. interval): Firmware
update in progress.
Off: Normal status.
b ODS CONTROL connector (ADI / power supply)
Connect to the DRIVE connector with the same number as
the drive on the ODS-L30M to supply power to the drive
unit and to enable ADI control.
