1-1 C HAPTER 1 A BOUT THE EZ S WITCH 10/100/1000 Overview SMC’ s EZ Switch 10/100/1000 SMCGS2 4C-Smart is a web managed switch with 24 10/100/1000B ASE-T ports, four of which are combination ports * th a t ar e s ha r e d w i t h f o u r S F P t ra n s ce i ve r s l o ts ( s ee F i g ur e 1 -1 , Por ts 21-24).
A BOUT THE EZ S WITCH 10/100/1000 1-2 Switch Architecture The switch employs a wire-speed, non-blocking switching fabric . This per mits simultaneous wire-speed transport of multiple pack ets at low latency on all por ts . The switc h also features full-duplex capability on all ports, which effecti vely doubles th e bandwidth of each connection.
D ESCRIPTION OF H ARDWARE 1-3 Description of Hardware 10/100/1000BASE-T Ports The switch contains 24 RJ-45 ports th at operate at 10 Mbps or 100 Mbps , half or full dupl ex, or at 1000 Mbps , full du plex.

2-1 C HAPTER 2 N ETWORK P LANNING Introduction to Switching A network switc h allows simultaneous transmission of multiple pac kets via non-crossbar switching .
N ETWORK P LANNING 2-2 Application Examples The EZ Switch 10/100/1000 is not only designed to segment your network, but also to pro vide a wide ra nge of options in setting up network connections .
A PPLICATION E XAMPLES 2-3 Central Wiring Closet With 24 parallel bridging ports (i.e., 24 distinct collision domains), this switch ca n collapse a complex netw ork do wn into a single efficient bridged node, increasing o verall bandwidth and throughput.
N ETWORK P LANNING 2-4 Remote Connections with Fiber Cable Fiber optic technolog y allows for longer cabling than any other media type. A 1000B ASE-SX (MMF) link can connect to a site up to 550 meters away , a 1000BASE-LX (SMF) link up to 5 km, and a 10 00B ASE-ZX link up to 100 km.
A PPLICATION E XAMPLES 2-5 Making VLAN Connections The switch supports VLANs that can be used to org anize any group of network nodes into separate broadcast domains. VLANs confine broadcast traffic to the originating group , and can eliminate broadcast stor ms in large networks .
N ETWORK P LANNING 2-6 Application Notes 1. Full-duplex operation only applies to point-to-point access (such as when a switch is attached to a work s tation, ser ver or another switch). When the switch is connected to a hub , both devices must operate in half-du plex mode .
