Gigabit Combo Ports
In addition to the 48 10/100 Mbps ports, the Switch features two Gigabit Ethernet Combo ports. These two ports are 1000BASE-T
copper ports (provided) and Mini-GBIC ports (optional). See the diagram below to view the two Mini-GBIC port modules being
plugged into the Switch. Please note that although these two front panel modules can be used simultaneously, the ports must be
different. The GBIC port will always have the highest priority.

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 - 5. 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 local console management through the RS-232
console port.
Link/Act – 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.
