Ethernet PHY User LEDs
[
Figure 1-2
, callout

]
The three Ethernet PHY user LEDs shown in
Figure 1-20
are located near the RJ45 Ethernet
jack P2. The on/off state for each LED is software dependent and has no specific meaning at
Ethernet PHY power on.
Refer to the Marvell 88E1116R Alaska Gigabit Ethernet transceiver data sheet for details
concerning the use of the Ethernet PHY user LEDs. They are referred in the data sheet as
LED0, LED1, and LED2. The data sheet and other product information for the Marvell
88E1116R Alaska Gigabit Ethernet Transceiver is available at the Marvell website
