1-1 Chapter 1: Introduction Overview The SM24-100SFP-AH is an intelligent switch with 24 100BASE SFP transceiver slots, two Gigabit combination ports 1 that are comprised of a RJ-45 port and an SFP transceiver slot and 2 Gigabit stacking ports. There is also an SNMP-based management agent embedded o...

Introduction 1-2 1 Switch Architecture The SM24-100SFP-AH switch employs a wire-speed, non-blocking switching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports. This switch also features full-duplex capability on all ports, which effectively doubl...

2-1 Chapter 2: Network Planning Introduction to Switching 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 mo...

2-2 Network Planning 2 Application Examples The SM24-100SFP-AH 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 in the following pages. Collapsed Backbone The SM24-100SFP-AH is an exce...

2-3 Application Examples 2 Network Aggregation Plan With 24 parallel bridging ports (i.e., 24 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 SFP ports on the switc...

2-4 Network Planning 2 Remote Connection with Fiber Cable 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 ...

2-5 Application Examples 2 Making VLAN Connections The SM24-100SFP-AH 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...

2-6 Network Planning 2 Application Notes 1. 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. 2. Avoid using flow control on...

3-1 Chapter 3: Installing the Switch Selecting a Site Switch units can be mounted in a standard 19-inch equipment rack or on a flat surface. Be sure to follow the guidelines below when choosing a location. • The site should: • be at the center of all the devices you want to link and near a power out...

3-2 Installing the Switch 3 Optional Rack-Mounting Equipment If you plan to rack-mount the switch, be sure to have the following equipment available: • Four mounting screws for each device you plan to install in a rack—these are not included • A screwdriver (Phillips or flathead, depending on the ty...

3-3 Mounting 3 2. Mount the device in the rack, using four rack-mounting screws (not provided). Be sure to secure the lower rack-mounting screws first to prevent the brackets being bent by the weight of the switch. Figure 3-2. Installing the Switch in a Rack 3. If installing a single switch only, tu...

3-4 Installing the Switch 3 3. If installing a single switch only, go to “Connecting to a Power Source” at the end of this chapter. 4. If installing multiple switches, attach four adhesive feet to each one. Place each device squarely on top of the one below, in any order. 5. If also installing an RP...
