SWITCH 3900 SYSTEM AND SETUP OVERVIEW |
|
This chapter contains:
■An overview of 3Com’s SuperStack® II Switch 3900 and how it provides solutions for your network
■A description of the major features and components of the system
■A network configuration example
The Switch 3900 is the ideal product for network managers who want to migrate from existing switched 10 Mb networks to switched 100 Mb or who need to deliver faster access to servers.
The Switch 3900 provides superior workgroup and departmental switching performance with the added flexibility of multiple Gigabit Ethernet links and server connections.
The SuperStack II Switch 3900 family delivers full line rate, nonblocking switching between 10/100 Mb links and 1000 Mb Gigabit Ethernet links.
The Switch 3900 family consists of two models:
■3C39024 — The 24-port 10/100BASE-TX switch, with up to three Gigabit Ethernet links. See Figure 1-1.
■3C39036 — The 36-port 10/100BASE-TX switch, with up to three Gigabit Ethernet links. See Figure 1-2.
Both versions of the Switch 3900 provide:
■One built-in Gigabit Ethernet multimode fiber (MMF) link (1000BASE-SX)
■Expansion slots on the back panel (see Figure 1-3) that can hold one or two of these optional Gigabit Ethernet modules:
■Model 3C39001 — 1000BASE-SX for multimode fiber (MMF)
■Model 3C39002 — 1000BASE-LX for single-mode fiber (SMF)
The cables for all Gigabit Ethernet ports use laser transmission and have SC connectors.
See “Optional Gigabit Ethernet Modules” on page 1-6 for more information.

Figure 1-3 Back Panel of the 24-Port and 36-Port SuperStack II Switch 3900
System Features and Benefits
The Switch 3900 is part of 3Com’s SuperStack family. To combine diverse technologies as your network grows, install the Switch 3900 in a SuperStack network.
Some key features of the SuperStack II Switch 3900 system:
■High-density Gigabit Ethernet and Fast Ethernet configurations
The Switch 3900 has 24 or 36 Fast Ethernet ports and up to three Gigabit Ethernet links.
■Autonegotiation support
The Switch 3900 supports 10BASE-T/100BASE-TX and full-duplex and half-duplex autonegotiation on all front panel ports.
■Multiple-link trunking for Gigabit Ethernet and Fast Ethernet links
You can choose the performance level of links between switches, even scaling beyond one Gigabit.
■IGMP Snooping
The Switch 3900 conserves the network bandwidth that is consumed by audio and video applications by keeping IP multicast traffic isolated to specific ports.
System Features and Benefits |
1-5 |
■Trunking links, Spanning Tree, and Advanced Redundant Power Supply (RPS) support
The Switch 3900 protects against cable and equipment failures with Spanning Tree Protocol and trunking links. The optional RPS protects against power interruptions for fault-tolerant networks.
■Manageability
The Switch 3900 provides full support for VLANs, Fast IP, and RMON Version 1, as well as a roving analysis port through SNMP management.
Switch 3900 systems include integrated management to provide fault tolerance and maximum network availability. This management is accessible in two ways:
■Switch 3900 Administration Console
■Standard network managers based on SNMP, such as 3Com’s Transcendware, Sun’s SunNet Manager, HP OpenView, and IBM’s NetView AIX applications
1-6 CHAPTER 1: SWITCH 3900 SYSTEM AND SETUP OVERVIEW
The Switch 3900 back panel has two expansion slots that can hold optional Gigabit Ethernet modules. These modules are available in the following configurations:
■1000BASE-SX Module — Multimode fiber with paired SC connectors. It supports links of up to 260 meters (852 feet) over 62.5-micron multimode fiber or up to 525 meters (1722 feet) over 50-micron multimode fiber.
■1000BASE-LX Module — Single-mode fiber with paired SC connectors. It supports links of up to 3.0 kilometers (1.86 miles) over 8-micron to 10-micron single-mode fiber.
The modules have the same physical configuration and are installed in the same way.
For more information about installing and using the optional Gigabit Ethernet modules, see the
1000BASE-SX/1000BASE-LX Gigabit Ethernet Module Installation Guide that is on the Documentation CD and shipped with either module.
Network Configuration Example
This section describes one way to place the Switch 3900 in your network to alleviate traffic congestion.
The rapid deployment of Fast Ethernet has increased bandwidth demand many times over, not only by supporting 100 Mb connections on the network but also by placing demands on the servers to manage the traffic coming through those connections.
Figure 1-4 shows how the Switch 3900 provides direct 100 Mb links to devices on the network through its Fast Ethernet ports and up to three dedicated Gigabit links to your network’s servers.
In this sample configuration, the Switch 3900 can provide up to 36 clients on your network with a dedicated 100 Mb link and can multiplex the client traffic for Gigabit-speed access to the servers. (You can use one port on the Switch 3900 for in-band management as well as for network traffic.)
