LED indicators for the Switch along with an explanation of each indicator.
Figure 3-12. The LED indicators
• Power – This indicator on the front panel should be lit during the Power-On Self Test (POST). It
will light green approximately 2 seconds after the switch is powered on to indicate the ready state
of the device.
• Console – This indicator is lit green when the Switch is being managed via out-of-band/local
console management through the RS-232 console port using a straight-through serial cable.
• Speed – On the right of each twisted pair port, this LED will light when the corresponding port is
operating at 100 Mbps. An unlit LED indicates a connection speed of 10 Mbps.
• Link/Act – These indicators are located to the left of each port. They are lit when there is a
secure connection (or link) to a device at any of the ports. The LEDs blink whenever there is
reception or transmission (i.e. Activity--Act) of data occurring at a port.
