SMA CLUSTER CONTROLLER, User Manual

Page: 108 / 114

Problem Cause and corrective measure
The Cluster Controller does not send
any data to Sunny Portal. The data transmission is incorrectly configured.
Corrective measures:
• If the Cluster Controller is not yet registered in
Sunny Portal, register the Cluster Controller in
Sunny Portal (see Section 11.1, page 56).
• Test the connection to Sunny Portal (see
Section 11.5, page 58).
• Check the settings for Sunny Portal (see Section 11,
page 56).
An error has occurred in the LAN.
Corrective measures:
• Check whether the network settings of the individual
network components are correct. Adapt the network
settings if required.
• Check whether the network components are
defective or damaged. Replace defective or
damaged network components.
After replacement of the Cluster Con-
troller, two systems with the same sys-
tem name appear in Sunny Portal. The system has been registered twice in Sunny Portal. The
new Cluster Controller logs into Sunny Portal with a new
system identifier. Sunny Portal creates a new system for
this system identifier, even if you have given the system the
same name.
Corrective measures:
• Assign the system identifier of the old system to the
replacement device (see Section 11.6, page 59).
• In the replacement device, enter the e-mail address of
a user who has administrator rights for the system in
Sunny Portal.
• In Sunny Portal, delete the new system created by the
replacement device.
