Compliances and Safety Warnings

FCC - Class A

This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction manual,
may cause harmful interference to radio communications. Operation of this equipment in
a residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his own expense.

You are cautioned that changes or modifications not expressly approved by the party
responsible for compliance could void your authority to operate the equipment.

You may use unshielded twisted-pair (UTP) for RJ-45 connections - Category 3 or better
for 10 Mbps connections, Category 5 or better for 100 Mbps connections, Category 5, 5e,
or 6 for 1000 Mbps connections. For fiber optic connections, you may use 50/125 or 62.5/
125 micron multimode fiber or 9/125 micron single-mode fiber.

Overview

The SM24-100SFP-AH is an intelligent switch with 24 100B ASE SF P transceiver
slots, two Gigabit combination ports

that are comprised of a RJ-45 port and an SFP
transceiver slot and 2 Gig abit stacking ports. There is al so an SNMP-based
management agent embedded on the main board. This agent supports both in-band
and out-of-band access for managing the switch.

This switch provides a broad range of powerful featur es for Layer 2 switching,
delivering reliability and consistent performan ce for your network traffic. It bring s
order to poorly performi ng n etw or ks by segregating them int o separate broadcast
domains with IEEE 802.1Q co m pl ia nt VLANs, and empowers mul timedia
applications with multi cas t s w itc hi ng an d C oS services.

Introduction

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 . Th is sw itc h als o fe atur es fu ll- dupl ex c apab il ity on al l por ts, whi ch ef fe cti vel y
doubles the bandwidth o f ea ch connection.

This switch uses store-and-forward switching t o ensure maximum data inte g rit y.

With store-and-forw ar d sw it chi ng, the entire packet must be received into a buffer
and checked for validity bef or e being forwarded. This pr ev ent s er rors from being
propagated throughout the network.

Network Management Options

The SM24-100SFP-A H contains a comprehensi ve ar r ay of LEDs for “at-a-glance”
monitoring of network and port status. It also includes a management agent that
allows you to configure or m oni tor the switch using its embe dde d management
software, or via SNMP applications. To manage a switch, you can make a direct
connection to the RJ-45 console port (out-of-band ), or you can manage it through a
network connection (in- band) using Telnet, the on-board Web agent, or
Windows-based net w or k m anagement software .

For a detailed descriptio n of the swi t ch’s ad van ced features, refer to the
Management Guide .

Description of Hardware

SFP Slots

The SM24-100SFP-AH swi t ch c ont ai ns 24 Sm all Form Factor Pluggable (SFP)
transceiver slots that operate at 100 Mbps full duplex. These slots support 100 Mbps
SFP Fast Ethernet transceivers. The supported tran sceiver types are listed belo w :

• SFP 100FX Multimode LC and optionally MTRJ

• SFP 100FX Single Mode LC

• SFP 100BX Single Mode LC Bidirectional Single Fiber (15 50 nm / 1310 nm)

This switch also has two Gigabit SFP transceiver slots shared with two RJ-45 ports
(Ports 26 and 28). In its defau l t co nf igur at i on, i f an SFP t ra nsceiver (purchased
separately) is installed in a slot and has a valid link on its port, the associated RJ-45
port is disabled and cannot be used. The switch can also be configured to force the
use of an RJ-45 port or SFP slot, as required.

Console Port

The RJ-45 serial port on the sw i tch’s fron t pa nel is used to connect to the swi tc h for
out-of-band console configuration. The on-board configuration program can be
accessed from a termin al or a P C running a terminal emulatio n pr ogr am .
