The Fast Ethernet Switch employs a wire-speed, non-blocking swi tching 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.
Network 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 di rect conne cti on 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.
For a detailed description of the switch’ s advanc ed features, refer to the Use r Guide.

Figure 1-1. Front Panel
10/100/1000BASE-T Ports
There are two types of RJ-45 ports, Ethernet ports that operate at 10 Mbps, 100
Mbps or 1000 Mbps, half or full duplex, and Fiber ports that operate at 1000 Mbps,
full duplex.
Because all ports on this switch support automatic MDI/MDI- X operation, you can
use straight-through cables for all network connections to PCs or servers, or to other
switches or hubs. (See “1000BASE-T Pin Assignments” on page B-30)
Each of these ports support auto-negotiation, so the optimu m tr ansmission mode
(half or full duplex), and data rate (10, 100, or 1000 Mbps) can be selected
automatically. If a device connected to one of these ports does not support
auto-negotiation, the communication mode of that port can be configured manually.
1-6
Description of Hardware
Each port also supports auto-negotiation of flow control, so the switch can
automatically prevent port buffers from becoming saturated.
On the LS-OS-6224U, there are two RJ-45 ports, which are shared with two of the
SFP transceiver slots.
1
SFP Slots
On all devices except the LS-OS-6224U, the Small Form Factor Pluggable (SFP)
transceiver slots are shared with two of the RJ-45 ports (Ports 25~26/49~50). 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 i s disabled and cannot
be used. The switch can also be configured to f orce the use of an RJ-45 port or SFP
slot, as required.
Note: Wh en selecting a fiber SFP device, considering saf ety, please make sure that
it can function at a temperature that is not less than the recommended
maximum operational temperature of the product. You must also use an
approved Laser Class 1 SFP transceiver.
Hinweis:Hinweis:Bei der Wahl eines Glasfasertransceivers muß für die Beurteilung der
Gesamtsicherheit beachtet werden, das die maximale Umgebungstemperatur
des Transceivers für den Betrieb nicht niedriger ist als die für dieses Produkts.
Der Glasfasertransceiver muß auch ein überprüftes Gerät der Laser Klasse 1
sein.

Chapter 3: Making Network Connections
Connecting Network Devices
This switch is designed to interconnect multiple segments (or collision domains). It
can be connected to network cards in PCs and servers, as well as to hubs, switches
or routers. It may also be connected to devices using optional SFP transceivers.
Twisted-Pair Devices
Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors
at both ends. Use Category 5, 5e or 6 cable for 1 000BASE-T connections, Category
5 for 100BASE-TX connections, and Category 3, 4 or 5 for 10BASE-T connections.
Cabling Guidelines
The RJ-45 ports on the switch support automatic MDI/ MDI-X pinout confi guration, so
you can use standard straight-through twisted-pair cables to connect to any other
network device (PCs, servers, switches, routers, or hubs).
See Appendix B for further information on cabling.
Caution: Do not plug a phone jack connector into an RJ-45 port. This will damage the
switch. Use only twisted-pair cables with RJ-45 connectors that conform to
FCC standards.
Connecting to PCs, Servers, Hubs and Switches
1. Attach one end of a twisted-pair cable segment to the device’s RJ-45
connector.
Figure 3-1. Making Twisted-Pair Connections
3-21
Making Network Connections
3
2. If the device is a PC card and the switch is in the wiring closet, attach the other
end of the cable segment to a modular wall outl et that is connect ed to the wiring
closet. (See “Wiring Closet Connections” on the next page.) Otherwise, attach
the other end to an available port on the switch.
3. Make sure each twisted pair cable does not exceed 100 meters (328 ft) in
length.
Note: Avoid using flow control on a port connected to a hub unless it is actually required
to solve a problem. Otherwise back pressure jamming signals may degrade
overall performance for the segment attached to the hub.
4. As each connection is made, the green Link LED (on the switch) co rresponding
to each port will light to indicate that the connection is valid.
Network Wiring Connections
Today, the punch-down block is an integral part of many of the newer equipment
racks. It is actually part of the patch p anel. Instructions f or making connections in the
wiring closet with this type of equipment follows.
1. Attach one end of a patch cable to an available port on the switch, and the other
end to the patch panel.
2. If not already in place, attach one end of a cable segment to the back of the
patch panel where the punch-down block is located, and the other end to a
modular wall outlet.
3. Label the cables to simplify future troubleshooting.

Fiber Optic SFP Devices
3
Fiber Optic SFP Devices
An optional Gigabit SFP transceiver (1000BASE-SX, or 1000BASE-LX) can be used
for a backbone connection between switches, or for connecting to a high-speed
server.
Each multimode fiber optic port requires 50/125 or 62.5/125 micron multimode fiber
optic cabling with an LC connector at both ends.
Each single-mode fiber port requires 9/125 micron single-mode fi ber optic cable with
an LC connector at both ends.
Caution: This switch uses lasers to transmit signals over fiber optic cable. The lasers are
compliant with the requirements of a Class 1 Laser Product and are inherently
eye safe in normal operation. However, you should never look directly at a
transmit port when it is powered on.
1. Remove and keep the LC port’s rubber cover. When not connected to a fiber
cable, the rubber cover should be replaced to protect the optics.
2. Check that the fiber terminators are clean. You can clean the cable plugs by
wiping them gently with a clean tissue or cotton ball moistened with a little
ethanol. Dirty fiber terminators on fiber cables will impair the quality of the light
transmitted through the cable and lead to degraded performance on the port.
3. Connect one end of the cable to the LC port on the switch and the other end to
the LC port on the other device. Since LC connectors are keyed, the cable can
be attached in only one orientation.
Figure 3-3. Making LC Port Connections
4. As a connection is made, check the green Link LED on the switch
corresponding to the port to be sure that the connection is val id.
The 1000BASE-SX and 1000BASE-LX fiber optic ports operate at 1Gbps full
duplex, with auto-negotiation of flow control. The maximum length for fiber optic
cable operating at Gigabit speed will depend on the fiber type as listed under
“1000 Mbps Gigabit Ethernet Collision Domain” on page 3-24.
3-23

Connectivity Rules
When adding hubs (repeaters) to your network, please follow the connect ivity rules
listed in the manuals for these products. However, note that because switches break
up the path for connected devices into separate collision domains, you should not
include the switch or connected cabling in your calculations for cascade length
involving other devices.
1000BASE-T Cable Requirements
All Category 5 UTP cables that are used for 100BASE-TX connections should also
work for 1000BASE-T, providing that all four wire p airs a re connect ed. However, it is
recommended that for all critical connections, or any new cable ins tallations,
Category 5e (enhanced Category 5) or Category 6 cable should be used. The
Category 5e specification includes test parameters that are only recommendations
for Category 5. Therefore, the first step in preparing exis ting Category 5 cabling for
running 1000BASE-T is a simple test of the cable installation to be sure that it
complies with the IEEE 802.3ab standards.

Cable Labeling and Connection Records
When planning a network installation, it is essenti al to label the opposing ends of
cables and to record where each cable is connected. Doing so will enable you to
easily locate inter-connected devices, isolate faults and change your topology
without need for unnecessary time consumption.
To best manage the physical implementations of your network, follow these
guidelines:
• Clearly label the opposing ends of each cable.
• Using your building’s floor plans, draw a map of the location of all
network-connected equipment. For each piece of equipment, identify the devices
to which it is connected.
• Note the length of each cable and the maximum cable length supported by the
switch ports.
• For ease of understanding, use a location-based key when assigning prefixes to
your cable labeling.
• Use sequential numbers for cables that originate from the same equipment.
• Differentiate between racks by naming accordingly.
• Label each separate piece of equipment.
• Display a copy of your equipment map, including keys to all abbreviations at each
equipment rack.

Diag LED is Red • Try power cycling the switch to clear the condition.
• If the condition does not clear, contact your dealer for assistance.
Power and Cooling Problems
If the power indicator does not turn on when the power cord is plugged in, you may
have a problem with the power outlet, power cord, or internal power supply.
However, if the unit powers off after running for a while, check for loose power
connections, power losses or surges at the power outlet, and verify that the fans on
the unit are unobstructed and running pri or to shutdown. I f you still canno t isolate the
problem, then the internal power supply may be defective.
Installation
Verify that all system components have been properly installed. If one or more
components appear to be malfunctioning (such as the power cord or network
cabling), test them in an alternate environment where you are sure that all the other
components are functioning properly.
In-Band Access
You can access the management agent in the switch from anywhere within the
attached network using Telnet, a Web browser, or other network management
software tools. However, you must first configure the switch with a valid IP address,

subnet mask, and default gateway. If you have trouble establishing a link to the
management agent, check to see if you have a valid network connection. Then
verify that you entered the correct IP address. Also, be sure the port through which
you are connecting to the switch has not been disabled. If it has not been disabled,
then check the network cabling that runs between your remote location and the
switch.
Caution: The management agent can accept up to four simultaneous Telnet sessions. If
the maximum number of sessions already exists, an additional Telnet
connection will not be able to log into the system.

All 1000BASE-T 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.
The table below shows the 1000BASE-T MDI and MDI-X port pinouts. These ports
require that all four pairs of wires be connected. Note that for 1000BASE-T
operation, all four pairs of wires are used for both transmit and receive.
Use 100-ohm Category 5, 5e or 6 unshielded twisted-pair (UTP) or shielded

Cable Testing for Existing Category 5 Cable
Installed Category 5 cabling must pass tests for Attenuation, Near-End Crosstalk
(NEXT), and Far-End Crosstalk (FEXT). This cable testing information is spec ified in
the ANSI/TIA/EIA-TSB-67 standard. Additionally, cables must also pass test
parameters for Return Loss and Equal-Level Far-End Crosstalk (ELFEXT). These
B-30
Fiber Standards
tests are specified in the ANSI/TIA/EIA-TSB-95 Bulletin, “The Additional
Transmission Performance Guid elines for 100 Ohm 4-Pair Category 5 Cabling.”
Note that when testing your cable installation, be sure to include all patch cables
between switches and end devices.
Adjusting Existing Category 5 Cabling to Run 1000BASE-T
If your existing Category 5 installation does not meet one of the test parameters for
1000BASE-T, there are basically three measures that can be applied to try and
correct the problem:
1. Replace any Category 5 patch cables with high-performance Category 5e or
Category 6 cables.
2. Reduce the number of connectors used in the link.
3. Reconnect some of the connectors in the link.
B
Fiber Standards
The current TIA (Telecommunications Industry Association) 568-A specification on
optical fiber cabling consists of one recognized cable type for horizontal subsystem
and two cable types for backbone subsystems.
Horizontal 62.5/125 micron multimode (two fibers per outlet).
Backbone 62.5/125 micron multimode or single mode.
TIA 568-B will allow the use of 50/125 micron multimode optical fiber in both the
horizontal and backbone in addition to the types listed above. All optical fiber
components and installation practices must meet applicable building and safety
codes.
