Switch Architecture

The switch employs a wire-speed, non-blocking switching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports. The switch also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection.

The 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.

PoE/Link

This switch includes two Gigabit combination ports with RJ-45 connectors and associated SFP slots. The optional SFP stacking transceiver enables up to eight units to be connected together through a 1 Gbps stack backplane. The switch stack can be managed from a master unit using a single IP address.

Power-over-Ethernet Capability

The switch’s 24 10/100 Mbps ports support the IEEE 802.3af Power-over-Ethernet (PoE) standard that enables DC power to be supplied to attached devices using wires in the connecting Ethernet cable. Any 802.3af compliant device attached to a port can directly draw power

1-2

Page 23

from the switch over the Ethernet cable without requiring its own separate power source. This capability gives network administrators centralized power control for devices such as IP phones and wireless access points, which translates into greater network availability.

For each attached 802.3af-compliant device, the switch automatically senses the load and dynamically supplies the required power. The switch delivers power to a device using the two data wire pairs in UTP or STP. Each port can provide up to 15.4 W of power at the standard -48 VDC voltage. Independent overload and short-circuit protection for each port allows the switch to automatically shut down a port’s power when limits are exceeded.

Network devices such as IP phones, wireless access points, and network cameras, typically consume less than 10 W of power, so they are ideal for Power-over-Ethernet applications.

Network Management Options

With a comprehensive arrange of LED indicators, this switch provides “at a glance” monitoring of network and port status. The switch can be managed over the network with a web browser or Telnet application, or via a direct connection to the console port. The switch includes a built-in network management agent that allows it to be managed in-band using SNMP or RMON (Groups 1, 2, 3, 9) protocols. It also has an RS-232 serial port (DB-9 connector) on the front panel for out-of-band management. A PC may be connected to this port out-of-band via a options.)

Description of Hardware

10/100BASE-T Ports

The PoE switch base unit contains 24 10BASE-T/100BASE-TX RJ-45 ports. All 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 “10/100BASE-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 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 IEEE 802.3x auto-negotiation of flow control, so the switch can automatically prevent port buffers from becoming saturated.

1000BASE-T/SFP Ports

These are combination Gigabit RJ-45 ports with alternate Small Form Factor Pluggable (SFP) transceiver slots. If an SFP transceiver (purchased separately) is installed in a slot, the associated RJ-45 port is disabled.

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 “1000BASE-T Pin Assignments” on page B-5.)

Note: The 1000BASE-T RJ-45 ports do not support PoE capability.

Introduction to Switching

A network switch allows simultaneous transmission of multiple packets via non-crossbar switching. This means that it can partition a network more efficiently than bridges or routers. The switch has, therefore, been recognized as one of the most important building blocks for today’s networking technology.

When performance bottlenecks are caused by congestion at the network access point (such as the network card for a high-volume file server), the device experiencing congestion (server, power user, or hub) can be attached directly to a switched port. By using full-duplex mode, the bandwidth of the dedicated segment can be doubled to maximize throughput.

When networks are based on repeater (hub) technology, the distance between end stations is limited by a maximum hop count. However, a switch turns the hop count back to zero. So subdividing the network into smaller and more manageable segments, and linking them to the larger network by means of a switch, removes this limitation.

A switch can be easily configured in any network to significantly boost bandwidth while using conventional cabling and network cards.

Application Examples

The switch is not only designed to segment your network, but also to provide a wide range of options in setting up network connections. Some typical applications are described below.

Supplying PoE

The switch is an excellent choice for supplying power to connected PoE devices such as web cameras, IP telephones or access points. You can easily connect a PoE device to the network and build on this basic configuration, to allow power to be delivered over the connection to the PoE device. Each of the 24 ports on the switch can provide power to a connected device.

In the figure below, the switch is supplying power to 3 PoE devices. It is also providing dedicated 100 Mbps full-duplex connections to the devices. In addition, other non-PoE devices can be connected to the switch.

Collapsed Backbone

The switch is an excellent choice for mixed Ethernet, Fast Ethernet, and Gigabit Ethernet installations in which significant growth is expected in the near future. You can easily build on this basic configuration, adding direct full-duplex connections to workstations or servers. When the time comes for further expansion, just connect to another hub or switch via one of the switch’s Fast Ethernet or Gigabit Ethernet ports.

In the figure below, the switch is operating as a collapsed backbone for a small LAN. It is providing dedicated 10 Mbps full-duplex connections to workstations and 100 Mbps full-duplex connections to power users and servers. In addition, connected IP phones and wireless access points are receiving PoE power from the switch.

Network Aggregation Plan

With 24 parallel bridging ports (i.e., 24 distinct collision domains), the switch can collapse a complex network down into a single efficient bridged node, increasing overall bandwidth and throughput.

When up to eight switch units are stacked together, they form a single “virtual” switch containing up to 200 ports. The whole stack can be managed through the Master unit using a single IP address.

In the figure below, the 10BASE-T/100BASE-TX ports in a switch stack are providing 100 Mbps connectivity for up to 72 segments. In addition, the stack is also connecting several servers at 1000 Mbps.

Remote Connections with Fiber Cable

Fiber optic technology allows for longer cabling than any other media type. Using a 1000BASE-SX multimode fiber (MMF) SFP transceiver, you can run a link up to 550 m, a 1000BASE-LX single-mode fiber (SMF) link can run up to 5 km, and a 1000BASE-LH single-mode fiber (SMF) link can run up to 70 km. This allows the switch to serve as a collapsed backbone, providing direct connectivity for a widespread LAN.

1000BASE-LX, 1000BASE-LH, or 100BASE-FX SFP transceivers can be used to interconnect remote network segments, or can be used to provide a link to other buildings in a campus setting. 1000BASE-SX SFP transceivers can be used for Gigabit fiber connections between floors in the same building.

The figure below illustrates this switch connecting multiple segments with fiber cable.

Making VLAN Connections

This switch supports VLANs which can be used to organize any group of network nodes into separate broadcast domains. VLANs confine broadcast traffic to the originating group, and can eliminate broadcast storms in large networks. This provides a more secure and cleaner network environment.

VLANs can be based on untagged port groups, or traffic can be explicitly tagged to identify the VLAN group to which it belongs. Untagged VLANs can be used for small networks attached to a single switch. However, tagged VLANs should be used for larger networks, and all the VLANs assigned to the inter-switch links.

The switch also supports multiple spanning trees which allow VLANs groups to maintain a more stable path between all VLAN members. This can reduce the overall amount of protocol traffic crossing the network, and provide a shorter reconfiguration time when any link in the spanning tree fails.

PPLICATION NOTES

Application Notes

1. Full-duplex operation only applies to point-to-point access (such as when a switch is attached to a workstation, server or another switch). When the switch is connected to a hub, both devices must operate in half-duplex mode.

2. 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.

3. As a general rule the length of fiber optic cable for a single switched

link should not exceed:

• 1000BASE-SX: 550 m (1805 ft) using multimode fiber

• 1000BASE-LX: 5 km (3.2 miles) using single-mode fiber

• 1000BASE-LH: 70 km (43.5 miles) using single-mode fiber

• 100BASE-FX: 20 km (12.43 miles) using single-mode fiber

• 100BASE-FX: 2 km (1.24 miles) using multimode fiber

However, power budget constraints must also be considered when

calculating the maximum cable length for your specific environment.

Selecting a Site

Switch units 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 50 °C (32 to 122 °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 LED indicators to be clearly visible

• Make sure that 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 m (6.6 feet) of each device

- is powered from an independent circuit breaker

Connecting Network Devices

The switch is designed to be connected to 10 or 100 Mbps network cards in PCs and servers, as well as to other switches and hubs. It may also be connected to remote devices using the optional 1000BASE-X, or 100BASE-FX SFP transceivers.

If 802.3af-compliant PoE devices are connected to the switch’s 10/100 Mbps ports, the switch automatically supplies the required power.

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 or better for 100BASE-TX connections, and Category 3 or better for 10BASE-T connections.

ETWORK

ONNECTIONS

4-1

Page 56

AKING NETWORK CONNECTIONS

Power-over-Ethernet Connections

The PoE switch automatically detects an 802.3af-compliant device by its authenticated PoE signature and senses its required load before turning on DC power to the port. This detection mechanism prevents damage to other network equipment that is not 802.3af compliant.

Note: Power-over-Ethernet connections work with all existing Category

3, 4, 5, 5e or 6 network cabling, including patch cables and patch-panels, outlets, and other connecting hardware, without requiring modification.

The switch delivers power to a device using the two signal wire pairs in UTP or STP cable (RJ-45 pins 1, 2, 3, and 6). The switch can provide up to

15.4 W of power continuously on each 10/100 Mbps port. However,

taking into account some power loss over the cable run, the amount of power that can be delivered to a terminal device is 12.95 W. If a device draws more than 15.4 W, from a port, an overload condition occurs and the port turns off the power.

The switch controls the power and data on a port independently. Power can be requested from a device that already has a data link to the switch. Also, the switch can supply power to a device even if the port’s data connection has been disabled. The power on a port is continuously monitored by the switch and it will be turned off as soon as a device connection is removed.

4-2

Page 57

WISTED-PAIR DEVICES

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 normal 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 4-1 Making Twisted-Pair Connections

4-3

Page 58

AKING NETWORK CONNECTIONS

3. If the device is a network 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 the section “Network Wiring Connections” on page 4-4) 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.

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 Link LED (on the switch) corresponding 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 newer equipment racks. It is actually part of the patch panel. Instructions for making connections in the wiring closet with this type of equipment follow.

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. See “Cable Labeling and Connection Records” on page 4-9.

Fiber Optic Devices

An optional slide-in 1000BASE-SX, 1000BASE-LX, 1000BASE-LH, or 100BASE-FX SFP transceiver may be used for backbone or remote connections, or for connecting to a high-speed server.

Each single-mode fiber optic port requires 9/125 micron single-mode fiber optic cabling with an LC connector at both ends. Each multimode fiber optic port requires 50/125 or 62.5/125 micron multimode fiber optic cabling with an LC connector at both ends.

Warning: 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.

Note: When selecting a fiber SFP device, considering safety, 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: 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.

1. Remove and keep any protective port covers. When not connected to a fiber cable, the 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 optic cables will impair the quality of the light transmitted through the cable and lead to degraded performance on the port.

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 valid.

The 100BASE-FX fiber optic transceiver operates at 100 Mbps, full duplex. The 1000BASE-SX, 1000BASE-LX and 1000BASE-LH fiber optic transceivers operate at 1 Gbps, full duplex. The maximum length for fiber optic connections will depend on the fiber type as listed under “1000 Mbps Gigabit Ethernet Collision Domain” on page 4-8.

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 and 6 specifications include 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.

4-9

Page 64

AKING NETWORK CONNECTIONS

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.

Diagnosing Power Problems with the LED Indicators

The Power and RPU LED indicators work in combination to indicate power status as follows.

Table A-2 Power/RPU LED Indicators

Power LED RPU LED Status

Green Green Internal power functioning normally; RPU is

present.

Green Amber Internal power functioning normally; RPU plugged

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, the internal power supply may be defective.

A-2

Page 67

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.

Note: The management agent accepts 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.

Stack Troubleshooting

If a stack fails to initialize or function, first check the following items:

• Check that all stacking cables are properly connected.

• Check if any stacking cables appear damaged.

• Check that only one Master Select button is pressed in.

• Check that all switches in the stack are powered on.

After checking all items, reboot all the switches in the stack. If the problem is still not resolved, contact your dealer for assistance.

Twisted-Pair Cable and Pin Assignments

For 10/100BASE-TX connections, the twisted-pair cable must have two pairs of wires. For 1000BASE-T connections the twisted-pair cable must have four 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: DO NOT plug a normal phone jack connector into any RJ-45

port. Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards.

Caution: Each wire pair must be attached to the RJ-45 connectors in a

specific orientation. (See “Cabling Guidelines” on page 4-3 for an explanation.)

Figure B-1 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.

10/100BASE-TX Pin Assignments

Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45 connections: 100-ohm Category 3 or better cable for 10 Mbps connections, or 100-ohm Category 5 or better cable for 100 Mbps connections. Also be sure does not exceed 100 meters (328 feet).

Data and PoE power are delivered on the standard two wire pairs (pins 1, 2, 3, and 6). Since 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.

Straight-Through Wiring

If the twisted-pair cable is to join two ports and only one of the ports has an internal crossover (MDI-X), the two pairs of wires must be straight-through. (When auto-negotiation is enabled for any RJ-45 port on this switch, you can use either straight-through or crossover cable to connect to any device type.)

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-X and MDI 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

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. Cables must also pass test parameters for Return Loss and Equal-Level Far-End Crosstalk (ELFEXT). These 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.

IBER STANDARDS

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 to 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.

Fiber Standards

The current TIA (Telecommunications Industry Association) 568-A specification on optical fiber cabling consists of one recognized cable type for horizontal subsystems 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.
