Chapter 1

Introduction to the BayStack 303 and 304

Ethernet Switches

This chapter introduces the BayStack 303 and 304 Ethernet Switches and covers the following topics:

• Summary of key features

• Physical description

Features

The BayStack 303 and 304 Ethernet Switches are members of the Bay Networks BayStack family of high-performance Ethernet solutions. Both BayStack 303 and 304 switches have built-in management software and power-up diagnostics that allow the switch to begin Ethernet frame switching functions immediately. These BayStack switches provide switch connectivity between 802.3 Ethernet device running any network protocols.

The BayStack 303 and 304 switches have 10 Mb/s ports, autonegotiating 10/100 Mb/s ports, and a 100 Mb/s media adapter (MDA) slot for either a 10/100BASE-TX or a 100BASE-FX ﬁber port connection.

The 10BASE-T port density of the BayStack 303 switch is ideal for low-cost performance-enhancing segmentation within the wiring closet, and the higher port density of the BayStack 304 switch allows the extension of dedicated switching to power desktop users. The 100 Mb/s ports provide a high-throughput connection to a backbone or server and can be conﬁgured to operate in either half- or full-duplex data transfer mode. The 100BASE-T ports can also be used to provide a link between traditional 10BASE-T networks and the faster 100BASE-T networks.

893-01010-A 1-1

Using the BayStack 303 and 304 Ethernet Switches

Multiple switches can be connected to one another (or to other 802.1D bridges/ switches/hubs) to form a switched/segmented (or bridged) Ethernet backbone.

Key features of the BayStack 303 and 304 Ethernet Switches are:

• Provides 10 Mb/s and 100 Mb/s switching in the following conﬁgurations:

— 12 (BayStack 304) or 24 (BayStack 303) 10BASE-T half-duplex ports

with standard RJ-45 connections — One 10/100BASE-TX half- or full-duplex autonegotiating port — Addition of an optional 10/100BASE-TX half- or full-duplex

autonegotiating copper port or 100BASE-FX ﬁber port

• Supports IEEE 802.3u autonegotiation standard on 10/100BASE-TX ports

• Supports up to 1024 media access control (MAC) addresses per switch

• Provides store-and-forward switching mode

• Provides signiﬁcant aggregate throughput for all packet sizes, including the minimum size (64 bytes) Ethernet frame:

— 420,000 packets per second (pps) for BayStack 304 Ethernet Switch — 380,000 pps for the BayStack 303 Ethernet switch

• Supports IEEE 802.1d Spanning Tree Protocol on each port to provide automatic network conﬁguration of a loop-free topology and redundant inter-switch links

• Supports broadcast and multicast trafﬁc control

• Provides user interface that supports international languages: English, German, French, Italian, Spanish, Japanese, and Chinese

• Supports in-band Telnet connections through any port

• Provides SNMP (Simple Network Management Protocol) manageability through any port; supports MIB II and Bridge MIB

• Supports Groups 1, 2, 3, and 9 RMON

• Supports TFTP remote software image download

• Provides indicators for power, system, and port operation

10BASE-T Ports

The 10BASE-T port connections are provided for the 10 Mb/s Ethernet segment or nodes to attach to the BayStack 303 and 304 Ethernet Switches. The RJ-45 jacks accept standard Category 3, 4, or 5 copper unshielded twisted pair (UTP) cable connections. Pin assignments for the standard RJ-45 connector are given in

able 1-1. The BayStack switches are shipped with the 10BASE-T connectors

conﬁgured as MDI-X (media-dependent interface-crossover). These ports connect over straight cables to the network interface controller (NIC) card in a node or server, similar to a conventional Ethernet repeater hub. If you are connecting to another Ethernet hub or Ethernet switch, you need a crossover cable unless an MDI connection exists on the associated port of the attaching device (see

Connecting 10BASE-T Ports” on page 2-8 for a description of the crossover

The 10 Mb/s ports operate in half-duplex mode only, and each port has an associated LED that indicates link status of the line.

10/100BASE-TX Port

Both the BayStack switches have one built-in and one optional 10/100BASE-TX port that is designed to operate either at 10 Mb/s or at 100 Mb/s depending on the connecting device. This port supports the IEEE 802.3u autonegotiation standard, which means that when this port is connected to another device that also supports the IEEE 802.3u autonegotiation standard, the two devices negotiate the best speed and duplex mode of operation.

The 10/100BASE-TX port also supports half- and full-duplex mode operation. For more information on autonegotiation, see “

Connecting the 10/100BASE-TX

Port” on page 2-9.

The 10/100 Mb/s port consists of a standard 8-pin modular RJ-45 connector used to connect hubs, switches, and end stations using only 2-pair Category 5 UTP cabling.

The link status indicator for the 100BASE-TX port is located on the LED panel on the front of the switch. This area also contains a full-duplex (F Dx) status indicator that lights when the port is operating in full-duplex mode. When the port is operating in half-duplex mode, the indicator is off. See “

Half-duplex and

Full-duplex Mode” on page 2-9 for more information on duplex mode.

A speed LED (100) is also provided to indicate when the port is operating as a 100 Mb/s port. The LED is off when the port is operating as a 10 Mb/s port. See

Autonegotiation” on page 2-10 for more information on autonegotiation of wire

speed. Like the 10BASE-T ports, all 10/100B ASE-T ports are also conﬁgured as MDI-X.

able 1-1 on page 1-5 lists the pin assignments for the RJ-45 connector.

MDA Slot

Each BayStack switch is conﬁgured with one expansion slot that can be populated with an optional plug-in media-dependent adapter (MDA) to support a high-speed connection to servers, shared Fast Ethernet hubs, or backbone devices. Two types of media adapters are available for the BayStack switches:

• Model MTX-1, 10/100BASE-TX copper connection

• Model MFX-1, 100BASE-FX ﬁber connection

Both media types support half- and full-duplex operation and have an LED to indicate when the port is operating in full-duplex mode. See Appendix

“Technical Speciﬁcations,” for a full description of the MDA.

Warning: Power to the switch must be turned off prior to installation of the

MDA.

Console Port Connector

The console port has a DB-9 male connector used to connect a management terminal to the BayStack switch by means of a straight-through DB-9 to DB-9 standard serial port cable. Using a terminal, you can monitor the results of startup self-diagnostics, perform manual boot conﬁguration and SNMP agent conﬁguration, and customize your network using the supplied menus and screens.

The console port runs at 9600 baud and uses 8 data bits, 1 stop bit, and no parity as the communications format, with ﬂow control disabled.

In less complex applications with no network management, where no conﬁguration changes are required, you do not need to use the console port on the BayStack switches.
