All the platforms can operate as standalone systems, or can be stacked together in the same system.

Switch Architecture

The Fast Ethernet 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.
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

Introduction

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. For a detailed description of the switchs advanced features, refer to the User Guide.

Description of Hardware

Figure 1-1. 100Base-TX 48 Ports Front Panel
Figure 1-2. 100Base-FX 24 Ports 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 C-16) Each of these ports support auto-negotiation, so the optimum transmission 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. Each port also supports auto-negotiation of flow control, so the switch can automatically prevent port buffers from becoming saturated. On the OS-LS-6224U, there are two RJ-45 ports, which are shared with two of the SFP transceiver slots.

SFP Slots

On all devices except OS_LS_6224U 100Base-FX ports, 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 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.

Status LEDs

The LEDs, which are located on the front panel for easy viewing, are shown below and described in the following table.

Chapter 2: Installing the Switch

Selecting a Site

Switches 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 outlet. be able to maintain its temperature within 0 to 45C (32 to 113 F) and its humidity within 5% to 95%, non-condensing provide adequate space (approximately two inches) on all sides for proper air flow be accessible for installing, cabling and maintaining the devices allow the status LEDs to be clearly visible Make sure twisted-pair cable is always routed away from power lines, fluorescent lighting fixtures and other sources of electrical interference, such as radios and transmitters. Make sure that the unit is connected to a separate grounded power outlet that provides 100 to 240 VAC, 50 to 60 Hz, is within 2.44 m (8 feet) of each device and is powered from an independent circuit breaker. As with any equipment, using a filter or surge suppressor is recommended.

To connect a device to a power source: 1. Insert the power cable plug directly into the receptacle located at the back of the device.
Figure 2-6. Power Receptacle 2. Plug the other end of the cable into a grounded, 3-pin socket.
Note: For International use, you may need to change the AC line cord. You must use a line cord set that has been approved for the receptacle type in your country.
Check the front-panel LEDs as the device is powered on to be sure the Power LED is lit. If not, check that the power cable is correctly plugged in. If you have purchased a Backup Power Supply, connect it to the switch and to an AC power source now, following the instructions included with the package.
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 1000BASE-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 configuration, 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 devices RJ-45 connector.
Figure 3-1. Making Twisted-Pair Connections
Making Network Connections
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 outlet that is connected to the wiring closet. (See Wiring Closet Connections on the next page.) Otherwise, attach the other end to an available port on the switch. Make sure each twisted pair cable does not exceed 100 meters (328 ft) in length.

Figure 3-3. Making LC Port Connections
As a connection is made, check the green Link LED on the switch corresponding to the port to be sure that the connection is valid.
The 1000BASE-SX and 1000BASE-LX fiber optic ports operate at 1 Gbps (100BASE-FX at 100Mbps) 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.
Note: Fiber statistics will be displayed only if the SFP supports digital diagnostics.

Connectivity Rules

When adding hubs (repeaters) to your network, please follow the connectivity 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 pairs are connected. However, it is recommended that for all critical connections, or any new cable installations, 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 existing 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 essential 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 buildings 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.

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 prior to shutdown. If you still cannot 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,

Troubleshooting

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.

Appendix C: Cables

Twisted-Pair Cable and Pin Assignments
Caution: DO NOT plug a phone jack connector into any RJ-45 port. Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards.
For 10BASE-T/100BASE-TX connections, a twisted-pair cable must have two pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be green and the other, green with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable.

Caution: Each wire pair must be attached to the RJ-45 connectors in a specific orientation. (See Cabling Guidelines on page 3-21 for an explanation.)
The figure below illustrates how the pins on the RJ-45 connector are numbered. Be sure to hold the connectors in the same orientation when attaching the wires to the pins.
1 Figure C-1. RJ-45 Connector Pin Numbers
10BASE-T/100BASE-TX Pin Assignments
Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45 connections: 100-ohm Category 3, 4 or 5 cable for 10 Mbps connections or 100-ohm Category 5 cable for 100 Mbps connections. Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet). The RJ-45 ports on the switch base unit 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. In straight-through cable, pins 1, 2, 3, and 6, at one end of the cable, are connected straight through to pins 1, 2, 3, and 6 at the other end of the cable. When using any RJ-45 port on this switch, you can use either straight-through or crossover cable.

1000BASE-T Pin Assignments
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 twisted-pair (STP) cable for 1000BASE-T connections. Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet). Table C-2. 1000BASE-T MDI and MDI-X Port Pinouts 1000BASE-T MDI and MDI-X Port Pinouts

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 specified 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

Fiber Standards

tests are specified in the ANSI/TIA/EIA-TSB-95 Bulletin, The Additional Transmission Performance Guidelines 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. 2. 3. Replace any Category 5 patch cables with high-performance Category 5e or Category 6 cables. Reduce the number of connectors used in the link. Reconnect some of the connectors in the link.
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.
