FTP Server
An FTP server can be configured to be on the ETCNet2 network and act as a file storage
location for the configuration files of the group.
An FTP server is not provided as standard with a CEM+.
CEM+ modules can access any stock FTP server that is configured with the following
minimum settings:
• IP address of the FTP server needs to match the one specified in the network table in
the configuration.
• The CEM+ uses an authenticated login so the FTP server must have a user created
and configured for the CEM+. (The user name and password are usually casesensitive.)
• User name: etc
• Password: sensor
• The FTP server must have a specified default file storage location. The CEM+ does not
specify any path to write the file to on the server. They will only go in the default root
directory.
WARNING: By default, you cannot currently use an FTP server with more than one (1)
rack group at the same time. All CEM+ modules will send their
configurations to the FTP server with the same file names and the same
directory (root) and will overwrite other configuration files present.
Contact ETC Technical Services if this is a requirement of your system.
System Maintenance
Replacing a CEM+ Control Module
Step 1:
Step 2:
Step 3:
CAUTION:
Open the rack door and locate the control module labeled CEM+ within the rack.
Though no harm is expected by removing the control module live, ETC
recommends powering down the rack before removing any rack components.
Remove existing control module as explained in Remove a CEM+ Module on
page 49
Install the new control module in the rack and use your thumbs on the outer edge
of the control module to firmly seat the module in its connectors until you feel it
hit the back of the connector.
CEM+ uses high density edge card connections to pass power and data to and
from the rack which requires 7 lbs insertion force. A partially inserted CEM+ may
result in incorrect operation or even damage to components of the rack.
Step 4:
Apply power to the Sensor+ rack.
Verifying the Configuration of the New Control Module
For Single Rack Systems
Sensor+ racks contain a backplane memory chip that allows the CEM+ to detect upon boot
if it holds the correct configuration for the system. If the CEM+ was last booted with the
same configuration, it will finish booting with its local copy of the group configuration and
