HOOTING
(b) Backup of Power Supply Module
The power supply module of each system can be backed up.
By adding backup power supply modules to system A and system B, even if an
error occurs in the power supply system connected to one power supply module,
or if the power supply module fails, the other power supply module can continue
the operation.
This enables the faulty power supply system to be restored, and the faulty power
supply module can be replaced while the system is running.
The power supply module can also be replaced for preventive maintenance while
the system is running.
(c) Module which can be mounted to main base unit or extension base unit
For the module which can be mounted to the main base unit or extension base
unit, refer to Section 2.3.
(d) Redundant System Operations
Refer to Section 5.1, for redundant system operations.
POINT
The extension base unit cannot be connected to the main base unit where the
Redundant CPU whose first 5 digits of serial No. is "09011" or earlier is mounted.
If connected, a stop error "BASE LAY ERROR (error code: 2010)" occurs.
When connecting the extension base unit, use the Redundant CPU whose first 5
digits of serial No. is "09012" or later.
