7.2 Replacing the modules used with CP 443-1 RNA

NOTICE
Behavior in PRP mode
If you start the download, this can lead to a timeout being indicated in PRP mode. In this
case, restart the download. You should also refer to the explanation in the section
Communication in PRP mode (Page 50)
What to do if a download is interrupted
Disturbances or collisions on the network can lead to packets being lost. In such cases, this
can lead to an interruption of the firmware download. The firmware loader then signals a
timeout or negative response from the module being loaded. En entry is made in the
diagnostics buffer. The CP restarts with the firmware that existed before the aborted
download.
Repeat the download using the active MAC address after the CP has started up again.
If you cannot start the download again following an aborted attempt, you should turn off the
entire rack and turn it on again. You can then restart the firmware download.
Note
PRP mode
A timeout may be indicated in PRP mode. In this case, restart the firmware download again.
