1-6CHAPTER 1: SWITCH 3900 SYSTEM AND SETUP OVERVIEW

Optional Gigabit Ethernet Modules

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.

Providing Dedicated Links for Fast Ethernet

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.)
