Rear Panel - Sony ODS-series Benutzerhandbuch

Rear panel

The following illustration depicts the ODS-L30M with
two drive units and two power supply units installed.
a Power supply unit mount slots
Allows you to provide a redundant power supply by
installing ODBK-101 optional power supplies (not
supplied). Doing so provides continuous operation in the
event one of the power supply units fail in systems that
require a high degree of reliability.
For details on adding or replacing power supply units,
consult your local Sony representative.
b Main power switches
Switch the main power supplies on or off. When using the
unit, leave these switches set to on, and use the on/standby
button on the front panel to switch between the operation
and standby modes.
Note
When turning the main power supplies off, always set the
unit to standby mode using the on/standby button on the
front panel before pressing these switches.
c AC IN connectors
Connect these to power outlets using power cords.
d Drive unit indicators
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.
42
Name and Function of Parts
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).
Slow blinking green (1-sec. interval): The drive is
initializing.
Rapid blinking green (0.25-sec. interval): Firmware
update in progress.
Off: Normal status.
e 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 (Automation/Drive Interface)
control.
f FC (Fibre Channel) connectors
Allow you to connect to servers and external storage via a
Fibre Channel switch.
