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/

Chapter 1: Introduction
Overview
The SM24-100SFP-AH is an intelligent switch with 24 100BASE SFP transceiver
slots, two Gigabit combination ports1 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 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 features for Layer 2 switching,
delivering reliability and consistent performance for your network traffic. It brings
order to poorly performing networks by segregating them into separate broadcast
domains with IEEE 802.1Q compliant VLANs, and empowers multimedia
applications with multicast switching and CoS services.

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
doubles the bandwidth of each connection.
This switch uses store-and-forward switching to ensure maximum data integrity.
With store-and-forward switching, the entire packet must be received into a buffer
and checked for validity before being forwarded. This prevents errors from being
propagated throughout the network.
Network Management Options
The SM24-100SFP-AH contains a comprehensive array of LEDs for “at-a-glance”
monitoring of network and port status. It also includes a management agent that
allows you to configure or monitor the switch using its embedded 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 network management software.
For a detailed description of the switch’s advanced features, refer to the
Management Guide.
Description of Hardware
SFP Slots
The SM24-100SFP-AH switch contains 24 Small Form Factor Pluggable (SFP)
transceiver slots that operate at 100 Mbps full duplex. These slots support 100 Mbps
SFP Fast Ethernet transceivers. The supported transceiver types are listed below:
• SFP 100FX Multimode LC and optionally MTRJ
• SFP 100FX Single Mode LC
• SFP 100BX Single Mode LC Bidirectional Single Fiber (1550 nm / 1310 nm)
This switch also has two Gigabit SFP transceiver slots shared with two RJ-45 ports
(Ports 26 and 28). In its default configuration, if an SFP transceiver (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 switch’s front panel is used to connect to the switch for
out-of-band console configuration. The on-board configuration program can be
accessed from a terminal or a PC running a terminal emulation program.
