Chapter 1: About the Switch
Overview
This switch is an intelligent Fast Ethernet switch with 24 10BASE-T / 100BASE-TX
(RJ-45) Ports and 2 Slots for 100BASE-FX or Gigabit Uplink Modules. This switch
can easily tame your network with full support for Spanning Tree Protocol, Multicast
Switching, Virtual LANs, and Layer 2/3/4 CoS services.
Figure 1-1. Front and Rear Panels
Switch Architecture
The FMS-24K 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.
Auto-negotiation is used to select the optimal transmission speed and
communication mode for each connection. With store-and-forward switching and
flow control, maximum data integrity is always maintained, even under heavy
loading.
This switch includes two slots on the front panel for slide-in 1000BASE-LX,
1000BASE-SX, 1000BASE-T, 100BASE-FX, or 1000BASE-X (GBIC) modules.
Cascade connections between switches can be made using these modules.
The switch also supports a stacking module that can be installed into slot Module 2.
The stacking module allows up to eight units to be linked together and managed
from one unit using one IP address.

Management Options
This switch 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 the switch, you can make a direct connection to the
RS-232 console port (out-of-band), or you can manage the switch through a network
connection (in-band) using Telnet, the on-board Web agent, or Windows-based
network management software.
The management agent provides a wide range of advanced performance-enhancing
features. Port-based VLANs provide traffic security and efficient use of network
bandwidth. QoS priority queueing ensures the minimum delay for
moving real-time
multimedia data through the switch. Flow control
eliminates the loss of packets due to
bottlenecks caused by port saturation. Port security is provided to filter unwanted
traffic from the switch.
For a detailed description of the switch’s advanced features, refer to the
Management Guide.
Description of Hardware
RJ-45 Ports
The switch base unit contains 24 10BASE-T/100BASE-TX RJ-45 ports. All of these
ports support automatic MDI/MDI-X operation, so you can use straight-through
cables for all network connections to PCs or servers, or to other switches or hubs.
(See “10BASE-T/100BASE-TX Pin Assignments” on page B-2.)
Each of these ports support auto-negotiation, so the optimum transmission mode
(half or full duplex), and data rate (10 or 100 Mbps) can be selected automatically, if
this feature is also supported by the attached device. If a device connected to one of
these ports does not support auto-negotiation, the correct speed will be sensed by
the port, but the transmission mode will default to half duplex.
Each port also supports auto-negotiation of flow control, so the switch can
automatically prevent port buffers from becoming saturated.

Port Status LEDs
The base unit also includes a display panel for key system and port indications that
simplify installation and network troubleshooting. The LEDs, which are located on
the front panel for easy viewing, are shown below and described in the following

This module supports 5 V 1000BASE-SX, 1000BASE-LX and 1000BASE-LH GBIC
transceivers:
1000BASE-SX GBIC transceivers provide one short-wavelength (850 nm) Gigabit
port that can be used for a high-speed backbone or server connection. This port can
be connected to a site up to 220 m (722 ft) away with 62.5/125 micron multimode
fiber cable, or up to 500 m (1641 ft) with 50/125 micron multimode fiber cable.
1000BASE-LX GBIC transceivers provide one long-wavelength (1300 nm) Gigabit
port that can be used for a high-speed backbone or server connection. This port can
be connected to a site up to 5 km (16404 ft) away with single-mode fiber cable.
1000BASE-LH GBIC transceivers provide one long-wavelength (1550 nm) Gigabit
port that can be used for a long-haul connection to a remote location. This port can

The module provides two 1 Gbps ports via USB Type-A connectors. The right port is
a transmit port and the one on the left a receive port. The module allows up to eight
switches to be linked together using stacking cables (ordered separately). The push
button on the module enables one switch in the stack to be selected as the master.
Combo Module

To connect a device to an SFP port, do the following:
1. Use your cabling requirements to select an appropriate SFP transceiver type.
2. Insert the SFP transceiver (sold separately) into an SFP slot. The slot’s LED
indicator turns on to confirm that it is correctly installed.
The 1000BASE-T RJ-45 ports support automatic MDI/MDI-X operation, so you can
use straight-through cables for all network connections to PCs or servers, or to other
switches or hubs. (See “10BASE-T/100BASE-TX Pin Assignments” on page B-2.)
