SLC 500 Memory Retention Characteristics

The 1747-BA supports SLC 500 processor RAM memory retention by supplying backup voltage when normal chassis power is unavailable. The battery circuit is designed specifically for maintaining stored processor memory data.

Battery replacement timing depends on controller operating conditions, storage environment, and power cycle frequency. Firmware and processor memory operation remain dependent on the installed SLC 500 CPU configuration.
