# 4. Buttons and Switches

This section describes the buttons and switches on the debug board

# 4.1 Buttons

Power Button: with this button, the PWRBTN# signal for the COM Express module can be triggered

Reset Button: with this button, the SYS\_RESET# signal for the COM Express module can be triggered

# 4.2 Switch

With this 4 pole DIP switch, several modes can be selected

<table><tr><td>Switch #</td><td>Function</td></tr><tr><td>1</td><td>POST WATCHDOGON = DisableOFF = Enable (default)</td></tr><tr><td>2</td><td>BIOS MODEON = PICMG MODEOFF = FAILSAFE MODE (default)</td></tr><tr><td>3</td><td>BIOS FAILSAFE MODEON = Boot from SPI0 (default)OFF = Boot from SPI1</td></tr><tr><td>4</td><td>NOT USED</td></tr></table>

# 5. Port 80 and LEDs

This section describes the hexadecimal display and LED functionality

# 5.1 Port 80 Display

During power-up and BIOS execution, the CPU will first retrieve commands from POST and then execute them. Each command has a corresponding debug port data code or BIOS POST checkpoint code. The results from each checkpoint can be reviewed on the LED display so the technician or administrator can properly debug the system. The POST code is written on I/O port 80 hex

The POST code is shown on the two 7-segment LED displays on the debug board

The Port 80 decoding interface is dependent on module design.

# 5.2 LED Indicators

LED Function

<table><tr><td>CB_RESET#</td><td>LED will lit on active rest signal for carrier board</td></tr><tr><td>CB_PWROK</td><td>LED will lit on active power OK from COM Express module</td></tr><tr><td>SLP_S3#</td><td>LED will lit on released SUS_S3# signal from COM Express module</td></tr><tr><td>SLP_S4#</td><td>LED will lit on released SUS_S4# signal from COM Express module</td></tr><tr><td>SLP_S5#</td><td>LED will lit on released SUS_S5# signal from COM Express module</td></tr><tr><td>EC_STATUS</td><td>LED will show the status of the BMC on the COM Express module</td></tr><tr><td>PWR_BTN#</td><td>LED will lit on active power button signal for COM Express module</td></tr><tr><td>SYS_RESET#</td><td>LED will lit on active reset signal for COM Express module</td></tr></table>

# 5.3 EC Status LED

The EC state and status of (also known as BMC status) is indicated via LEDs

<table><tr><td>Behavior</td><td>Description</td></tr><tr><td colspan="2"></td></tr><tr><td>Blinking status LED</td><td>A blinking Status LED indicates a failure during power-up. The number of flashes indicates the error code. A missing/wrong system voltage, stuck on the reset line, BIOS failure, or an unexpected shutdown of an on-board power supply can all trigger this signalling code. Error codes are board specific. Please check the corresponding COM Express module manual for details.</td></tr><tr><td>Bright blue flash</td><td>A system state change occurs. Power-button activity, Reset-button activity, PCI_RST# activity or activity on SLP_Sx signals can all trigger this signalling mode.</td></tr><tr><td>Fast blinking status LED</td><td>If and when the board is running on Fail-Safe-BIOS, the Status LED will be blinking extremely fast until addressed.g</td></tr><tr><td>Short bright blue flashes every 4s</td><td>System is in Suspend-to=RAM.</td></tr></table>
