Feature Descriptions
Ethernet PHY User LEDs
[
, callout 21]
The three Ethernet PHY user LEDs shown in
are located near the RJ45 Ethernet
jack P3. The on/off state for each LED is software dependent and has no specific meaning at
Ethernet PHY power on.
Refer to the Marvell 881116R Alaska Gigabit Ethernet transceiver data sheet for details
concerning the use of the Ethernet PHY user LEDs. They are referred to in the data sheet as
LED0, LED1, and LED2. See the data sheet and other product information for the Marvell
881116R Alaska Gigabit Ethernet Transceiver
