893-01010-A 4-1 Chapter 4 T roub leshooting and Diagnostics The BayStack 303 and 304 Ethernet Switches are designed to be as simple and reliable as possible. Occasionally , problems may arise that are largely associated with two areas: problems related to the BayStack switches and problems related to the installation.
Using the BayStack 303 and 304 Ethernet Switches 4-2 893-01010-A A utonegotiation Port connection problems can occur when a port is connected to a station that is not operating in a compatible mode (for example, connecting a full-duple x port to a half-duplex port).
Troubleshooting and Diagnostics 893-01010-A 4-3 MDI and MDI-X Connections BayStack switches use MDI-X ports that allo w you to connect directly to end stations without using crossov er cables (see Figure 4-1 ). Ports that implement the crossov er function internally are known as MDI-X ports (where “X” refers to the crossov er function).
Using the BayStack 303 and 304 Ethernet Switches 4-4 893-01010-A If you are connecting a de vice to the BayStack switches that also implements MDI-X ports (see Figure 4-2 ), use a crossov er cable.
Troubleshooting and Diagnostics 893-01010-A 4-5 Addresses Remember that the BayStack switches each hav e a MA C station address and an IP address. The MA C station addresses are unique because each address contains the Bay Networks manufacturer ID and node ID codes.
Using the BayStack 303 and 304 Ethernet Switches 4-6 893-01010-A The 100 Mb/s ports are designed to operate using Category 5 UTP cabling only . Category 5 UTP cable is a 2-pair cable certified to handle up to 100 MHz bandwidth.
