Miscellaneous Checks

Check for speciﬁc hardware problems, such as broken traces or loose and/or broken solder connections.

If you have installed the adapter correctly and you still experience problems, check the software.

Make sure that you have installed the correct drivers for the network operating system you are running (refer to Chapter 4, “Loading Network Drivers”).

If any problem persists, refer to Appendix B, “Technical

Support.”

Link Beat LED

The 3C592 EISA adapters have an LED for the link beat (see Figure 1-1). The link beat LED conﬁrms that there is an active connection between the adapter and the hub.

When you ﬁrst install the adapter and power up the computer, the LED lights, but the link beat is inactive. For the link beat to be active (enabled), you need to have run the Group 3 test or have loaded the network drivers.

If you are experiencing any problems, ﬁrst make sure that your hub complies with the 10BASE-T speciﬁcations and then check the LED. The meaning of LED activity is given below:

■If the LED is on, the link beat is working.

■If the LED is off, the link beat has not been established or there is a problem with the connection between the adapter and the hub.

■If the LED is blinking, the cable polarity is reversed.
