Operation & Maintenance Notes

Install redundant paired controllers on matched dual-slot dedicated carrier, assign different segment IP for dual Ethernet ports to avoid network conflict

Separate Ethernet signal cable from high-power AC wiring to reduce electromagnetic interference

Check front panel indicator status regularly; cut off corresponding slot power before module disassembly replacement
