Link LED

The 3C509B NICs have a light-emittingdiode (LED) that indicates whether an active 10BASE-T network connection exists between the NIC and the hub. The LED flashes if the polarity of the network cable is reversed.

When you first install the NIC and power on the computer, the LED lights, but the network link is inactive. To enable the network link, you must install the network driver.

Table 1-2 describes the LED states.

Table 1-2NIC LED Interpretation

LED State	Meaning
On	If drivers are installed, the connection is active.
	If drivers are not installed, this state indicates that the NIC is
	receiving power.
Off	If the LED is not lit, something is preventing the connection
	between the NIC and the hub.
Blinking	If the LED is blinking, the cable polarity is reversed. Try a
	different network cable or contact your MIS representative.

If the NIC LED indicates a problem, check the following:

1Ensure that your network hub and the network cable connecting to your EtherLink III NIC comply with the 10BASE-T specifications.

2Ensure that the hub is powered on.
