|
|
|
|
| Pin | Signal | Comments |
|
|
|
|
| A1 | Logic_GND | Logic ground connection (long contact); provides return path for power and signal |
| connections. | ||
|
|
| |
|
|
|
|
| A2 | Shelf_GND | Shelf ground connection (long contact); provides safety ground contact between |
| SBC and RTM. | ||
|
|
| |
|
|
|
|
| B1 | Logic_GND | Logic ground connection (long contact); see above. |
|
|
|
|
| B2 | +3.3V_MP | Management power (long contact); provides up to 100mA to power management |
| system on RTM. Used exclusively for management power. | ||
|
|
| |
|
|
|
|
| C1 | IPMI_Sclk | IPMB/I2C clock signal (medium contact) |
| C2 | IPMI_Sdata | IPMB/ I2C data signal (medium contact); This signal is connected to the on board |
| ADM1026 for temperature and voltage monitoring on the RTM. | ||
|
|
| |
|
|
|
|
| D1 | 12V | 12V RTM payload power (short contact); provides up to 420mA to power active |
|
|
| devices (other than management system) on RTM. See additional requirements |
| D2 | 12V | |
| below. | ||
|
|
|
|
|
|
| Presence Signal, active low (short contact); the RTM connects this signal to |
| E1 | PS1# | Logic_GND through a 100 Ohm resistor (to facilitate manufacturing test). The Front |
|
|
| Board reads this signal to understand if an RTM is fully inserted. |
|
|
|
|
| E2 | ENABLE# | Module enable signal, active low (short contact); the Front Board sets this signal high |
| to reset the RMC/RMD. | ||
