Table 5: SW10
Note:
The switch provides the ability toisolate these status indication
LEDs on this adapter and restrict the LEDs from power drawing.
SW10 ON means LEDs connected to the DUT power will be ON,
SW10 OFF means that the LEDS are disabled and drawing no
current.
Table 6: SW11
Note:
Switch used to select the 12V power source for the EDSFF
Connector.
Table 7: SW12
Note:
This switch is used to select the 3.3V power source for on
board circuitry in host adapter. 3.3V source could be either regulated
supply or from the PCIe slot (3P3V_Host).
Table 8: SW15
Note:
Jumper closed for PWRDIS signal is enabled, which indicates
the device to shut off 12V and related circuitry. Open for normal
operation.
