How to install Supermicro SuperChassis 743AC-1200B-SQ

• Prepare your workstation and rack: ensure you have a clean, static-free area and the appropriate rack rails and mounting hardware for a 4U chassis.
• Mount the chassis in the rack: align the chassis with the rack rails, secure it using the provided screws, and verify stability before proceeding.
• Install the motherboard: place your ATX, Micro ATX, or EATX motherboard into the chassis, align standoffs with the motherboard holes, and secure the board with screws. Attach the I/O shield if provided and route power and data connectors as required.
• Install the power supply and connect power: ensure the 1200 W power supply is securely mounted, connect the main power cable, and route cables for clean management inside the chassis.
• Install drives into the external bays: insert 3.5" drives into the eight external bays and 5.25" devices (if used) into the three external bays, securing them according to the chassis’ drive trays. Connect drive backplanes or SATA/SAS cables as appropriate for your configuration.
• Connect front panel and I/O cables: attach any front USB or status LEDs, connect chassis management cables if available, and verify all cables are tidy and clear of fans or drive doors.
• Finalize connections and test: power on the system, enter BIOS/UEFI, and configure boot order, storage arrays, and RAID where applicable. Verify all fans spin correctly and windows or your OS boots as expected.
