Table 51. Front Panel Connector (J9E3) (continued)
Pin | Signal | Type* | Description |
12 | FP_NMI_BTN* | in | FRONT PANEL NMI is connected to a BMC input port, |
|
|
| allowing the front panel to generate an NMI. FP_NMI_BTN* |
|
|
| is pulled high to +5 V on the baseboard and is intended to be |
|
|
| connected to a |
|
|
| GROUND when pushed) on the system front panel. |
13 | SM_IMB_SCL | in/out | I2C CLOCK is the clock signal for the Intelligent Platform |
|
|
| Management Bus. |
14 | FP_RST_BTN* | in | FRONT PANEL RESET is connected to the BMC. A hard |
|
|
| resent occurs and all baseboard devices, except for the BMC |
|
|
| are reset. FP_RST_BTN* is pulled high to +5V on the |
|
|
| baseboard, and is intended to be connected to a momentary- |
|
|
| contact push button (connected to GROUND when pushed) |
|
|
| on the system front panel. |
15 | +5V standby | power | +5 V STANDBY is the standby 5 volt power supply. |
16 | FP_PWR_BTN* | in | FRONT PANEL POWER CONTROL is connected to the |
|
|
| BMC and causes the power to toggle (on → off, or off → on). |
|
|
| FP_PWR_BTN* is pulled high to +5 V standby on the |
|
|
| baseboard and is intended to be connected to a momentary- |
|
|
| contact push button (connected to GROUND when pushed) |
|
|
| on the system front panel. |
17 | SM_FP_ISOL | in | SM_FP_ISOL, when asserted, isolates the front panel SM |
|
|
| bus. |
18 | GROUND | ground | GROUND is the power supply ground. |
19 | FAN_TACH(0) | in | FAN_TACH signal is connected to the BMC to monitor the |
|
|
| FAN speed. |
20 | FAN_TACH(1) | in | FAN_TACH signal is connected to the BMC to monitor the |
|
|
| FAN speed. |
21 | FAN_TACH(2) | in | FAN_TACH signal is connected to the BMC to monitor the |
|
|
| FAN speed. |
22 | FAN_TACH(3) | in | FAN_TACH signal is connected to the BMC to monitor the |
|
|
| FAN speed. |
23 | FAN_TACH(4) | in | FAN_TACH signal is connected to the BMC to monitor the |
|
|
| FAN speed. |
24 | FAN_TACH(5) | in | FAN_TACH signal is connected to the BMC to monitor the |
|
|
| FAN speed. |
25 | FAN_TACH(6) | in | FAN_TACH signal is connected to the BMC to monitor the |
|
|
| FAN speed. |
26 | FAN_TACH(7) | in | FAN_TACH signal is connected to the BMC to monitor the |
|
|
| FAN speed. |
27 | RJ45_ACTLED_R | in | NIC activity LED. |
28 | reserved | - | Reserved. |
29 | SM_PRI_SCL | in/out | I2C CLOCK is the clock signal for the Primary Private Bus. |
30 | SM_PRI_SDA | in/out | I2C DATA is the data signal for the Primary Private Bus. |
*Type (in, out, in/out, power, ground) is from the perspective of the baseboard.
