Notes:
1. This pin is not grounded on the Hawk since it can be used to detect the presence of an mSATA
module versus a Mini PCIe card.
2. This pin is not grounded on the Hawk to make it available for mSATA module detection.
3. This signal drives the top LED (D1) on the VL-CBR-5016 paddleboard. This LED lights with
mSATA disk activity (if supported by the mSATA module).
4. Some Mini PCIe cards use this signal as a second Mini PCIe card wireless disable input. On the
Hawk, this signal is available for use for mSATA versus Mini PCIe card detection. There is an
option on the VersaLogic Features BIOS setup screen for setting the mSATA detection method.

W_Disable# Signal

The W_DISABLE# is for use with optional wireless Ethernet Mini PCIe cards. The signal
enables you to disable a wireless card's radio operation in order to meet public safety regulations
or when otherwise desired. The W_DISABLE# signal is an active low signal that when driven
low (shorted to ground) disables radio operation on the Mini PCIe card wireless device. When
the W_DISABLE# is not asserted, or in a high impedance state, the radio may transmit if not
disabled by other means such as software.
