Front-Panel Components and LED Indicators

The front panel of the Switch consists of LED indicators for Power, Console, Link/Act and Speed, 8/16/24 Fast-Ethernet,
ports, two optional module ports (DES-3018/3026 only), a gigabit 1000BASE-T copper port (DES-3010F/G), a 100BASE-
FX Ethernet port (DES-3010F) and a SFP Gigabit Ethernet port (DES-3010G). Also, the front panel has a RS-232
communication port.
Comprehensive LED indicators display the status of the Switch and the network.

Description
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.
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.
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/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.
