1 INTRODUCTION OVERVIEW This device is an intelligent Layer 3 switch designed for delivering Fiber-To-TheHome (FTTH) high-speed Internet access. It can provide first or second level aggregation of fiber optic nodes. When functioning as a lower level aggregation device, it supports up to 24 subscribers through SFP fiber optic downlink connections to the customer’s premises equipment (CPE).
CHAPTER 1 | Introduction Description of Hardware For communications between different VLANs, this switch uses IP routing. For communications within the same VLAN, the switch uses store-and-forward switching to ensure maximum data integrity. With store-and-forward switching, the entire packet must be received into a buffer and checked for validity before being forwarded. This prevents errors from being propagated throughout the network.
CHAPTER 1 | Introduction Description of Hardware ◆ ■ 1000BASE-LX ■ 1000BASE-LH 100 Mbps Ethernet SFP transceivers ■ 100BASE-FX For information on the recommended standards for fiber optic cabling, see “1000 Mbps Gigabit Ethernet Collision Domain” on page 56. Each port supports auto-negotiation of flow control, so the switch can automatically prevent port buffers from becoming saturated.
CHAPTER 1 | Introduction Description of Hardware EXPANSION MODULE SLOTS The two expansion module slots on the switch are reserved for future use. 100BASE-TX MANAGEMENT PORT The 10/100BASE-TX port labeled “Management” provides a dedicated management interface which is segregated from the data traffic crossing the other ports.

3 MAKING NETWORK CONNECTIONS CONNECTING NETWORK DEVICES This switch is designed to interconnect multiple segments (or collision domains). It can be connected to network cards in PCs and servers, as well as to hubs, switches or routers. It may be connected to devices using optional SFP or XFP transceivers. TWISTED-PAIR DEVICES Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends.
CHAPTER 3 | Making Network Connections Twisted-Pair Devices CONNECTING TO PCS, SERVERS, HUBS AND SWITCHES 1. Attach one end of a twisted-pair cable segment to the device’s RJ-45 connector. Figure 16: Making Twisted-Pair Connections 2. If the device is a PC card and the switch is in the wiring closet, attach the other end of the cable segment to a modular wall outlet that is connected to the wiring closet. Otherwise, attach the other end to an available port on the switch.
CHAPTER 3 | Making Network Connections Fiber Optic SFP Connections FIBER OPTIC SFP CONNECTIONS Each of the optional SFP transceivers on the switch’s front panel can connect directly to a CPE at the subscriber’s premises. The transceiver ports require multimode duplex fiber optic cable with an LC connector at the switch end. The connector used at the other end of the cable depends on the target device. When connecting to a CPE, the fiber cable is normally hard-wired directly to the unit.
CHAPTER 3 | Making Network Connections Fiber Optic SFP Connections networking device, connect one end of the cable to the LC connector on one of the switch’s SFP transceivers and the other end to the LC port on the other device. Since both LC connectors are keyed, the cable can only be attached in the correct orientation.
