Issue
An XR frame can display an invalid address on its front 7 segment LCD display - 8, 9, 10 or 11, for example. The XR communication card may fail to communicate.
Product Line
Symmetra Power Array
Symmetra RM
Symmetra LX
Environment
Any UPS in the product families listed above with an extended run (XR) frame attached.
Cause
This is caused by setting the address dial on the back of the XR communication card (either SYXRCC or SYAFSU16) incorrectly.
Resolution
Check to ensure the XR communication card's address dial is set to a valid address. This problem has been observed when the dial is set to a position in between two valid addresses. If this has been checked and the problem continues, contact technical support.
