fw5_peripherals FULL WIRING SHEET 5 of 5 — OPTIPLEX 5080 MICRO: POWER, USB, AUDIO, CAN, DISPLAYS (rev 3.15) Port allocation rule: real-time/bandwidth devices DIRECT on the board (CAN, mic, phone); tolerant low-speed devices on ONE POWERED hub.  Built-in AX201 BT 5.2 = A2DP + BLE (no BT dongle). BIOS: Deep Sleep DISABLED (WOL needs 5VSB) · Smart Power On DISABLED · WOL/PXE ENABLED · replace the CR2032 (deep-storage 0W leaves only the coin cell holding the clock).
