Sony ODS-L30M Bedienungsanleitung Seite 47

Rear panel
The following illustration depicts the ODS-L60E with four
ODS-D280F/D380F drive units and two power supply
units installed. If ODS-D77F drive units are mounted, the
rear panel structure is different. For details about the
ODS-D77F, see "Rear panel (ODS-D77F)" (page 45).
a Power supply unit mount slots
Allows you to provide a redundant power supply by
installing ODBK-201 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.
A power supply unit is not required if a drive unit is not
installed in the ODS-L60E.
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 of the ODS-L30M before pressing these
switches.
c AC IN connectors
Connect these to power outlets using power cords.
d DC OUT connectors
Connect to the DC IN connectors of the ODS-D280F/
D380F drive units to supply power to the drive units.
These connectors are not used when ODS-D77F drive
units are mounted.
e Power supply unit indicators
Indicate the status of the power supply units.
Off: Normal status
Lit red: 19.5 V power supply error
f DRIVE 1 to 4 connectors (ODS control (ADI /
power supply))
Connect to the ODS CONTROL connector on the drive
unit with the same number (DRIVE 1 to 4) using an ODA
control cable (supplied with the drive unit) to enable ADI
control. When connected with an ODS-D77F, it supplies
power to the drive unit.
Note
When connecting the ODA control cable while the library
power supply is turned on, use the following procedure.
1. Connect the ODA control cable.
2. Connect the drive DC cable to the DC IN connector.
If the drive DC cable is connected first, the drive unit may
enter "Miscommunication" state, requiring the drive unit
to be restarted using the Library Maintenance Web UI.
Similarly, when removing a drive unit, use the following
procedure.
