Figure 2-1. Installing a Metal Chassis in a Rack To install the metal switch chassis in a 19-inch rack, you need to determine the exact location and position of the switch in the rack. The mounting brackets shipped with the metal chassis allow the positioning of the switch to be adjusted to accommodate your needs.
The plastic chassis requires different rack mounting brackets. The plastic chassis rack mounting brackets use slots in the sides of the chassis. Determine which position you want for the switch in the rack and select the appropriate slots (see Figure 2-1...
Page 40
There are three slots located on the side of the chassis. To install the switch flush with the rack, use the front and middle slots. To install the switch extended out from the rack, use the middle and back slots.
Completing Rack Mounting Installation Once the switch is secured to the rack, connect the devices and apply power using the following steps: Attach all devices to the ports. “Attaching Devices to the BayStack Attach the power cord to the back of the switch.
Attaching Devices to the BayStack Switch After you have installed the BayStack 303 or 304 switch, you can connect it to any equipment that conforms to the IEEE 802.3 standard, such as the following devices: • Ethernet networking devices •...
Connecting the 10/100BASE-TX Port Both BayStack 303 and 304 switches contain an onboard 10/100 Mb/s port that uses autonegotiation with the connecting device to determine the wire speed. An optional second 10/100 Mb/s port can be added by installing the 10/100BASE-TX MDA.
Page 44
All the high-speed ports on the BayStack 303 and 304 switches support full-duplex. For more information on autonegotiation, see “Autonegotiation” on page 4-2.
The serial console interface is an RS-232 port that enables a connection to a PC or terminal for monitoring and configuring the switch. You can also connect this port to an external modem to enable remote dial-in management of the switch. The port is implemented as a data communication equipment (DCE) connection, using a male DB-9 connector.

Menu and Screen Descriptions The BayStack 303 and 304 switch console interface consists of menu and screen displays that allow you to manage the switch and monitor its performance. Menus are provided to allow selection of switch parameters and a means to change and manipulate them.
The Language selection menu lists the seven languages in which you can display the BayStack user interface. This menu is displayed at the initial power-up sequence of the switch (when the switch is first turned on). Subsequent power-up procedures display the Main Menu. After you select a language, this menu is displayed only if you press Esc from the Main Menu.
System Information The System Information screen displays the current parameter settings for the switch. All of the screens associated with system information are read only. To change any parameter or setting you must go through the System Configuration menu. The System Information screen provides three paths to switch statistics and status information.
Page 62
This field allows you to define how many seconds elapse between hello time messages that are sent from this switch to all other switches, if the Spanning Tree Protocol has defined this switch as the root switch. This field is configurable in the range of 1 to 65535 seconds with a default of 2 seconds.

• Rx CRC Error Frame This counter increments whenever a frame is received on a particular interface that is an integral number of octets in length but does not pass the frame check sequence (FCS). • Rx Frame Too Long This counter increments whenever a frame is received on this port that is greater than 1,518 octets in length.
Port Status Information screen. System Configuration The System Configuration menu provides the means to change parameter settings within specific areas of the switch network. This menu contains the following selections: 1---Switch Network Configuration 2---Port Configuration...
Page 67
When multiple paths exist, the spanning tree algorithm configures the network so that a bridge/switch uses only the most efficient path. If that path fails, the protocol automatically reconfigures the network to make another path become active, sustaining network operations.
The Port Configuration menu allows the user to define the functions of the high-speed ports. On the BayStack 303 switch, this menu addresses ports 25 and 26. On a BayStack 304 switch, this menu addresses ports 13 and 14. Options provided on the Port Configuration menu are:...
Page 69
This field allows you to define how many seconds elapse between hello time messages that are sent from this switch to all other switches, if the Spanning Tree Protocol has defined this switch as the root switch. This field is configurable in the range of 1 to 65535 seconds with a default of 2 seconds.
SNMP Configuration The SNMP Configuration menu displays a list of the parameters that allow you to set and change values, parameters, and addresses within an SNMP management environment. To change any setting, type in the corresponding number. The screen is refreshed, and the command line displays the current parameter value for the selected parameter and allows you to enter new data.
• Management using SNMP Configuration Examples The BayStack 303 and 304 switches are well suited for the initial migration from shared 10BASE-T segments to dedicated bandwidth for switch connections between segments, end-stations, 100BASE-T Fast Ethernet servers, and fiber or copper Fast Ethernet backbone connections. The switches also function well as segment or desktop switches.
Page 72
BayStack 304 switch as a segment switch Figure 3-3 illustrates how a BayStack 304 switch can be used as a segment switch to alleviate server and network center contention and to provide better ratio connections to 10 Mb/s users. This configuration also offers an additional eight dedicated 10 Mb/s connections for users.
The BayStack 303 switch can be used as a desktop switch to provide 100 Mb/s connections to the server and network center and to give dedicated 10 Mb/s connections to up to 23 users instead of shared 10 Mb/s connections (see Figure 3-4).
Managing the BayStack Switches You can manage your BayStack 303 and 304 switches in any of the following three ways: • In-band signaling using SNMP (see page •...
Page 75
Access to the switch through SNMP is controlled by community names. The community names set for the switch must match those used by the SNMP management station for successful communication to occur. The switch uses two community names.
Network Management through a Serial I/O Connection Each BayStack 303 and 304 switch can be managed using a PC or terminal connected to the switch through the RS-232 console port located on the front of the switch. The serial connection allows the network manager to view statistics and change parameter settings using the built-in user interface.

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.
(see Configuration” on When the link is first brought up, the BayStack 303 and 304 switches sense the speed of the connecting device. If the connecting device changes speed without performing a link down, the BayStack switch can correctly sense a change from 100 Mb/s to 10 Mb/s;...
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. BayStack 303/304 switch MDI-X port Figure 4-1. MDI-X to MDI cable connections...
If you are connecting a device to the BayStack switches that also implements MDI-X ports (see BayStack 303/304 switch MDI-X port Figure 4-2. MDI-X to MDI-X cable connections Installation-related Issues Ethernet 10BASE-T networks tend to be fairly simple, but they can still have problems that take time to resolve.
Remember that the BayStack switches each have a MAC station address and an IP address. 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.
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. 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).
