1-1 C HAPTER 1 A BOUT THE T IGER S TACK 1000 Overview SMC’ s TigerStack 1000 SMC8724ML3 and SMC8748ML3 are intelligent multila yer switches (Layer 2, 3) with 24/48 10/100/1000BASE-T ports , four of which are co mbination por ts * that are shared with four SFP transceiv er slots (see Figure 1-1, P or ts 21-24/45-48).
A BOUT THE T IGER S TACK 1000 1-2 These switches can be used to augmen t or completely re place slow legacy routers , off-loading local IP traffic to release valuable resources for non-IP routing or W AN access.
D ESCRIPTION OF H ARDWARE 1-3 These switches include built- in stacking ports that enabl e up to eight units to be connected together through a 40 Gbps stack backplane .
A BOUT THE T IGER S TACK 1000 1-4 SFP Slots The Small Form Factor Plug gable (SFP) transc eiv er slots are shared with four of the RJ-45 ports (por ts 21-24 for the SMC8724ML3 and ports 45-48 for the SMC8748ML3).
D ESCRIPTION OF H ARDWARE 1-5 Port and System Status LEDs The switches include a display panel for k ey system and por t indications that simplify installation and network troubleshooting . T he LEDs, which are located on the front panel for easy viewing, are shown belo w and described in the following tables .

D ESCRIPTION OF H ARDWARE 1-7 Optional Redundant Power Unit SMC supports an optional Redundant P o wer Unit (RPU), that can supply pow er to the switch in the ev ent of failure of the internal power supply . Power Supply Sockets There are two po wer sock ets on the rear panel of each switch.
A BOUT THE T IGER S TACK 1000 1-8 Optional Media Extender Modules 10G Xenpak Module Figure 1-6 Single-Port 10G Module (Xenpak) The module Xenpak slot suppor ts all standard 10 Gigabit Ethernet (10G) Xenpak transceiv ers . All 10GB ASE transceiv ers operate at 10 Gbps full duplex.
F EATUR ES AND B ENEFITS 1-9 Features and Benefits Connectivity • 24/48 10/100/1000 Mbps ports for ea sy Gigabit Ethernet integration and for protection of your invest ment in legacy LAN equipment.
A BOUT THE T IGER S TACK 1000 1-10 • Switching table with a total of 16K MAC address entries and 8K IP address entries. • Provides store-and-forward switchin g for intra-VLAN traffic, and IP routing for inter-VL AN traffic. • Supports wire-speed switching at la yer 2, and wire-speed routing at layer 3.
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 Tig erStack 1000 is not only designed to segment your netw ork, but also to pro vide a wide rang e of opti ons in setting up netw ork connections and linking VLANs or IP subnets . Some typical applicati ons are described below .
A PPLICATION E XAMPLES 2-3 Network Aggregation Plan With 24 or 48 parallel bridging por ts (i.e., 24/48 distinct collision domains), these switches can collaps e a complex network do wn into a single efficient bridg ed node, in creasing 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 These switches support 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 stor ms in large networks .
N ETWORK P LANNING 2-6 Using Layer 3 Routing VLANs can significantly enhance ne tw ork perfor mance and security . Howev er , if you use con ventional routers to interconnect VLANs , you can lose most of your performance adva ntage.
A PPLICATION N OTES 2-7 Application Notes 1. Full-duplex operation only applies to point-to-point access (such as when a switch is attached to a w orkstation, ser ver or another switch). When the switch is connected to a hub , both devices must operate in half-du plex mode .
