Installation & Startup
- Power down rack OR perform hot-swap within 30 seconds
- Insert module into any 3500 slot and tighten captive screws to 0.5 N·m
- Launch RCU software - auto-detects 129131-01; set temperature alarm at 65°C, shutdown at 75°C
- Verify LED indicators - green "OK" steady indicates rack healthy; red "FAULT" indicates power or temperature error
- Test System OK relay - 3500/32 should energize when all power supplies are within specification
