Downloading Configuration Data to the Physical Island
Overview When you download a new island configuration to a physical island, the physical
island will start running the new configuration as soon as the download is complete.
If the physical island is running a protected configuration when you attempt to
download, you will not be able to complete the download until you have unprotected
the old configuration. If the protected configuration has a password, you will need to
enter it in order to unprotect the configuration.
Procedure To download the configuration to the physical island, select Download from the
Online pull-down menu.
The download process automatically wipes out the old configuration in the NIM’s
Flash memory and writes the new configuration to Flash.
When the download is complete, you can store the configuration to a removable
memory card if you choose.
Storing the
Configuration to
a Removable
Memory Card
After you download a new configuration to a physical island, you may optionally save
that new configuration to a removable memory card. The card serves as a backup
to the configuration in RAM and Flash.
There are several benefits to storing the configuration on a removable memory card:
If the NIM malfunctions and needs to be replaced, configuration data in the RAM
and Flash are lost. Configuration data on the card survives and can be used to
redownload data to the replacement NIM.
If you have multiple islands that need to run the same configuration, you simply
insert the card in the NIM of every island and cycle power. The configuration is
written to Flash from the card. This technique eliminates the need to carry a PC
with you to download to each physical island.
Procedure To save a configuration to a removable memory card, place a card in the card
drawer in your NIM and select Store to Removable Memory Card from the Online
pull-down menu. A detailed description of the card usage is provided in your NIM
documentation and in the on-line Help.
Note: If the physical island to which you are connected experiences a loss of power
or loss of communications during the download task, the software ends the task
and displays an error message. When you reestablish power/communications on
the physical island, it comes back in an autoconfigured state, and all previously
existing custom configuration values are lost. At this point, you should restart the
download procedure.
