LED Indicators

The front panels of the NetStacker II dual speed hubs display LED indicators, as shown in Figure 2-3. The LED nomenclature, color, and function are as follows:

❑Power (green): Illuminates when AC power is applied to the hub.

❑Collision “COL” (amber): A collision occurs when two or more sta- tions in the Ethernet network attempt to transmit data at the same time. The LED flashes to indicate a collision while the stations re- transmit. There is one LED for 10Mbps and one for 100Mbps.

❑Hub ID Number (green): Indicates the ID of the hub if it is part of a stack; this identifying number is auto-configured, from one to eight.

❑Link Activity “100Mbps/10Mbps” (green): Indicates that a device is connected to the port number, and that either a 10Mbps (lower LED) or 100Mbps (upper LED) link is detected. If the link is detected, the LED turns on. If data is transmitting, the LED blinks.
