1.5.5 Using the AutoConfiguration Adapter (ACA)

The ACAs are devices for saving the configuration data of a device. In the
case of a device failure, an ACA enables the configuration data to be trans-
ferred easily by means of a substitute device of the same type.
Note: If you replace a device with DIP switches, please ensure that the DIP
switch settings are identical.
Storing the current configuration data in the ACA:
You have the option of transferring the current device configuration, in-
cluding the SNMP password on the ACA and the flash memory in the
"Save" frame using the "to Switch / Save configuration" option.
Transferring the configuration data from the ACA:
When you restart the device adopts the configuration data of the ACA and
saves it permanently in the flash memory. If the connected ACA does not
contain any valid data, for example, if it is completely new, the device
loads the data from the flash memory.
Note: Before loading the configuration data from the ACA, the device
compares the password stored in the device with the password in the
ACA configuration data.
The device loads the configuration data if
The admin password matches or
There is no password stored locally or
The local password is the initial state of delivery password or
No configuration is saved locally.
