Miscellaneous Checks
Check for specific hardware problems, such as broken traces
or loose/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 3, “Installing the Network Drivers”).
If any problem persists, refer to Appendix C, “Technical
Support.”
Link Beat LED
The 3C590 PCI 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.
