Switch LED Indicators

The LED indicators of the Switch include Power, Console, and

Link/Act. The following shows the 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.

♦ Act/Link These indicators are located to the left and right 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.

Stacking Module LED Indicators

The switch’s current order in the switch stack is also displayed

on the Stacking Module’s front panel − under the STACK NO.
