Lion (VL-EPMe-42) Reference Manual
28
The VersaLogic VL-CBR-2402 cable is a USB 3.0 Type-C to Type-A socket adapter. The VL-
CBR-2402 cable can be used to connect the Lion to any certified USB 3.0 hubs.
LEDs
FPGA Controlled LEDs
The FPGA controls three LEDs (the Blue is an individual LED and the Green/Yellow is a dual-
package):
Blue – used for SATA (and mSATA) activity indication.
Green – used for Power-Good indication when in S0 (and will do a very low duty cycle
pulse when in sleep modes as an indication that the board is still powered).
Yellow – used for errors or debug (software enables this).
The Yellow LED can be also used for debug purposes.
Power LEDs
The power LED on the VL-CBR-4005 indicates that the paddleboard is being powered by the 3.3
V supply (though it does not indicate that all S0 power supplies are within specified limits). The
LED is lit only when the board is in the S0 power state. If the board enters a Sleep or Hibernate
mode, the LED will not be lit.
Power Button
Connector J13 includes an input for a power button. Shorting J13 (pin 17) to ground causes the
board to enter an S5 power state (similar to the Windows Shutdown state). Shorting it again
returns the board to the S0 power state and reboots the board. The button can be configured in
Windows to enter an S3 power state (Sleep, Standby, or Suspend-to-RAM), an S4 power state
(Hibernate or Suspend-to-Disk), or an S5 power state (Shutdown or Soft-Off).
The input can be connected to ground using the normally open contacts of a pushbutton switch or
a relay, or with a switching transistor (open-collector or open-drain) capable of sinking 1 mA. The
input must be driven to a voltage between 0 V and 500 mV to be recognized by the Lion. Do not
add an external pull-up resistor to this signal.
This connector uses IEC 61000-4-2-rated TVS components to help protect against ESD damage.
In configurations where a power button is not connected to the board, if the system is put into an
S5 state, power can be restored by turning off the power supply and turning it back on. This
behavior is set by default in the BIOS.
