89301010.BK Page 3 Tuesday, June 10, 1997 8:00 PM Installing the BayStack Switches 4. You can stack switches on top of one another to configure a switched/ bridged/segmented Ethernet backbone. For performance reasons, the high-speed ports should be used to interconnect switches. 5. Attach the power cord to the back of the switch. The BayStack switches do not have a power on/off switch. When you connect the AC power cord to a suitable AC outlet, the switch powers up immediately.

89301010.BK Page 10 Tuesday, June 10, 1997 8:00 PM Using the BayStack 303 and 304 Ethernet Switches The indicator for the built-in 100BASE-TX port is located on the LED panel on the right of the front panel. The indicator for the MDA port is located on the MDA. When the half- and full-duplex indicator is lit, the port is operating in full-duplex mode (meaning the port is operating at either 20 Mb/s or 200 Mb/s, depending on the connecting device).

In more complex networks, it is possible to route a message from any given source to any given destination by more than one path. Routing a message over multiple paths can cause several bridges to claim priority in sending the same message.

The use of SNMP, a common and well-defined protocol, allows the network manager to manage any SNMP-compliant device in a multivendor environment.

Upgrades can be incorporated into your BayStack switches by using Trivial File Transfer Protocol (TFTP) through a network connection from a networked PC or UNIX workstation acting as a TFTP file server.

Occasionally, problems may arise that are largely associated with two areas: problems related to the BayStack switches and problems related to the installation.

89301010.BK Page 2 Tuesday, June 10, 1997 8:00 PM Using the BayStack 303 and 304 Ethernet Switches Autonegotiation 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-duplex port to a half-duplex port). Problems and mismatches occur when the switch is connected to a port that either: • Does not support autonegotiation. • Supports a form of autonegotiation that is not compatible to the IEEE 802.

89301010.BK Page 3 Tuesday, June 10, 1997 8:00 PM Troubleshooting and Diagnostics MDI and MDI-X Connections BayStack switches use MDI-X ports that allow you to connect directly to end stations without using crossover cables (see Figure 4-1). Ports that implement the crossover function internally are known as MDI-X ports (where “X” refers to the crossover function). Note: For the transmitter of one device to connect to the receiver of another device, the sum of crossovers must always be an odd number.

The MAC station addresses are unique because each address contains the Bay Networks manufacturer ID and node ID codes. The switch is shipped with a default IP address of 000.000.000.000. It is not required to have a valid IP address for normal switching operation or if you are managing the switch from a console.

Category 5 UTP cable is a 2-pair cable certified to handle up to 100 MHz bandwidth. To minimize crosstalk noise, maintain the twist ratio of the cable up to the point of termination (untwist at any termination should not exceed 0.5 inches).

To use this port, a media dependent adapter (MDA) is inserted in the switch through the front panel. The media adapter slot accepts either a 100BASE-TX (UTP) or 100BASE-FX (fiber) media adapter to provide a switched Fast Ethernet link to high-speed servers, switches, hubs, or routers.
