Troubleshooting

This chapter provides several methods for troubleshooting problems related to the BayStack 22 PC Card Adapter.

Diagnostic LEDs

Three LEDs on the media coupler of the BayStack 22 network card provide diagnostic information. The 10 and 100 Mb/s Link LEDs indicate successful network connections to Ethernet and Fast Ethernet devices, respectively. The Link LEDs remain steady if the connection is stable. You should check the RJ-45 connection if the LED is not steady. The Activity LED indicates active network traffic.

Table 4-1 describes the Link and Activity LED indications.
