2.Blink amber 0-15 times while green stays off.

3.Blink green 0-15 times while amber stays off.

Note: See Section 8.2, “Port 80h POST Codes” for explanations of the codes.

5.5Reset Button

The Reset button is located in a small recessed hole near the serial port connector on the front panel. The Reset button is an input to the IPMC to request a cold reset. There are IPMI commands to reset the board and change power states through the software.

The Reset button is a last resort because someone must be physically present at the chassis to reset the board. The Reset button location on the front panel is shown in Figure 11.
