Page 23: Introduction
NTRODUCTION VERVIEW The GEL-2870 is a Gigabit Ethernet Layer 2 switch with 28 1000BASE-T ports, four of which operate in combination with four Small Form Factor Pluggable (SFP) transceiver slots (see Figure 1-1, Ports 25-28). The switch also includes an SNMP-based management agent, which provides both in-band and out-of- band access for managing the switch. -
Page 24: Description Of Hardware
| Introduction HAPTER Description of Hardware WITCH RCHITECTURE The switch employs a wire-speed, non-blocking switching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports. The switch also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection. -
Page 25: Table 1: Supported Sfp Transceivers
| Introduction HAPTER Description of Hardware Each port also supports IEEE 802.3x auto-negotiation of flow control, so the switch can automatically prevent port buffers from becoming saturated. SFP T RANSCEIVER LOTS The Small Form Factor Pluggable (SFP) transceiver slots are shared with four of the RJ-45 ports (ports 25-28). -

Page 29: Network Planning
ETWORK LANNING NTRODUCTION TO WITCHING A network switch allows simultaneous transmission of multiple packets via non- crossbar switching. This means that it can partition a network more efficiently than bridges or routers. The switch has, therefore, been recognized as one of the most important building blocks for today’s networking technology. -
Page 30: Application Examples
| Network Planning HAPTER Application Examples PPLICATION XAMPLES The switch is not only designed to segment your network, but also to provide a wide range of options in setting up network connections. Some typical applications are described below. OLLAPSED ACKBONE The switch is an excellent choice for mixed Ethernet, Fast Ethernet, and Gigabit Ethernet installations where significant growth is expected in the near future. -
Page 31: Figure 5: Network Aggregation Plan
| Network Planning HAPTER Application Examples ETWORK GGREGATION With 28 parallel bridging ports (i.e., 28 distinct collision domains), the switch can collapse a complex network down into a single efficient bridged node, increasing overall bandwidth and throughput. In the figure below, the 1000BASE-T ports on the switch are providing 100 Mbps connectivity for up to 28 segments. -
Page 32: Figure 6: Remote Connections With Fiber Cable
| Network Planning HAPTER Application Examples EMOTE ONNECTIONS WITH IBER ABLE Fiber optic technology allows for longer cabling than any other media type. A 1000BASE-SX (MMF) link can connect to a site up to 550 meters away, a 1000BASE-LX (SMF) link up to 5 km, and a 1000BASE-LH link up to 70 km. This allows the switch to serve as a collapsed backbone, providing direct connectivity for a widespread LAN. -
Page 33: Figure 7: Making Vlan Connections
| Network Planning HAPTER Application Examples VLAN C AKING ONNECTIONS This switch supports VLANs which can be used to organize any group of network nodes into separate broadcast domains. VLANs confine broadcast traffic to the originating group, and can eliminate broadcast storms in large networks. This provides a more secure and cleaner network environment. -
Page 34: Application Notes
| Network Planning HAPTER Application Notes PPLICATION OTES Full-duplex operation only applies to point-to-point access (such as when a switch is attached to a workstation, server or another switch). When the switch is connected to a hub, both devices must operate in half-duplex mode. -
