LED or Button Description
Power
This LED will light green after the Switch is powered on to indicate the normal operation
of the Switch’s power supplies. The indicator is dark when the Switch is powered off.
Console
This LED should blink during the Power-On Self Test (POST). When the POST is fin-
ished successfully, the LED goes dark. This indicator will light solid green when the
Switch is being logged into via out-of-band/local console management through the RS-
232 console port in the front of the Switch using a straight-through serial cable.
Link/Act
When the LED mode has been changed to Link/Act, the LEDs will light steady green to
indicate a valid link. A blinking LED indicates activity on the port.

To the right of every Link/Act LED lies the speed LED, corresponding to every port.
Depending on the switch model, these lights will assume different roles.
DES-3010F/FL/G – A solid green LED indicates the port is transferring data at
100Mbps while a dark, unlit LED will indicate a rate of 10Mbps.
Port 9 – The LED of this port, when lit solid green, indicates a transfer rate of
1000Mbps. When this LED is unlit, it denotes a transfer rate of 10/100Mbps.
Port 10 – For the 3010F and 3010FL, a solid green LED indicates a transfer
rate of 100Mbps and a dark LED indicates no link. For the 3010G, solid green LED
indicates a transfer rate of 1000Mbps and a dark LED indicates no link
DES-3018 / DES-3016 / DES-3026 – A solid green LED will indicate a valid link at
100Mbps, and when blinking, indicates the port is currently transferring data. A solid
amber LED will indicate a valid link at 10Mbps, and when blinking, indicates the port is
