2.9 Faulty Device Replacement
The device provides 2 plug-and-play solutions for replacing a faulty device
with a device of the same type (faulty device replacement):
Configuring the new device using an AutoConfiguration Adapter (see on
page 39 “Loading the system configuration from the ACA”) or
configuration via DHCP Option 82 (see on page 278 “Setting up a DHCP
Server with Option 82”)
In both cases, when the new device is started, it is given the same
configuration data that the replaced device had.
Note: If you are replacing a device with DIP switches, check the DIP switch
settings to ensure they are the same.
Note: If you want to access the device via SSH, you also need an SSH key.
To transfer the SSH key of the old device to the new one, you have the
following options:
- If you have already created the key and saved it outside the device (e.g. on
your administration workstation), load the saved key onto the new device
(see on page 289 “Uploading the key”).
- Otherwise create a new SSH key and load it onto the new device (see on
page 287 “Preparing access via SSH”). Note that the new device now
identifies itself by means of another key.
