Front of the Switch

Mode Select Button and Indicator LEDs

To optimize the amount of information that can be displayed for each of the
switch ports without overwhelming you with LEDs, the Switch 2224 uses a
Mode LED for each port. The operation of this LED is controlled by the Mode
Select button, and the current setting is indicated by the Mode indicator LEDs
near the button. Press the button to step from one mode to the next.

Port 1 Indicator LED

The LED labeled "100FX Port used as Port 1" indicates which of the switch
ports, the transceiver module or the fixed RJ-45 connector is being used as
the switch Port 1. Only one of these ports can be active at any time. If a
transceiver module is installed, it will automatically be selected by the switch
to be used for Port 1, and the LED will be lit, even if there is no active fiber-
optic cable connected to the transceiver.
If a non-supported transceiver is installed in the switch, for example a
100Base-TX twisted-pair transceiver, this LED remains off.

If the Activity (Act) indicator LED is lit, the Mode LED for each port
displays activity information for the port—it flickers as network traffic is
received and transmitted through the port.
If the Full Duplex (Fdx) indicator LED is lit, the Mode LEDs light for those
ports that are operating in full duplex.
If the 100 Mbps (100) indicator LED is lit, the Mode LEDs light for those
ports that are operating at 100 Mbps.
