Definition
Link/Activity LED – This yellow LED is the activity/link
indicator and provides the status of Ethernet port 1 (J23).
• A steady On LED indicates a link is established
• A flashing LED indicates active data transfers
Speed LED – This green LED is the Speed indictor and
indicates
transmit or receive speed of
• A steady Off LED shows the port at 10BaseT speed
• A steady On LED shows the port at 100BaseT speed
Definition
Link/Activity LED – This yellow LED is the activity/link indicator
and provides the status of Ethernet port 2 (J10).
• A steady On LED indicates a link is established
• A flashing LED indicates active data transfers
Speed LED – This green LED is the Speed indictor and indicates
transmit or receive speed of Ethernet port 2 (J10).
• A steady On LED indicates the port is at 10/100BaseT speed
• A steady Off LED indicates the port is at 1000BaseT speed
