Overview

The SMC6824MPE Power over Ethernet switch contains 24 10BASE-T/ 100BASE-TX RJ-45 ports and and two combination ports—10/100/ 1000BASE-T ports that operate in combination with Small Form Factor Pluggable (SFP) transceiver slots. An optional SFP stacking transceiver is available for connecting up to eight units to a 1 Gbps stack backplane.

All the 10BASE-T/100BASE-TX ports on the switch support IEEE 802.3af standard (802.3af) Power over Ethernet capabilities. Each port can detect connected 802.3af-compliant network devices, such as IP phones or wireless access points, and automatically supply the required DC power.

As well as its Power over Ethernet capabilities, the switch provides comprehensive network management features, such as Spanning Tree Protocol, multicast switching, virtual LANs, and Layer 2/3/4 CoS services that provide reliability and consistent performance for your network traffic.

Switch Architecture

The SMC6824MPE 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 SMC6824MPE 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

The 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 connection to any port on the stack using a single IP address.

Power over Ethernet Capability

The SMC6824MPE switch’s 24 front panel 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 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 SMC6824MPE switch automatically senses the load and dynamically supplies the required power. The switch delivers power to a device using the two wire pairs in UTP or STP cable that are not used for 10BASE-T/100BASE-TX connections. 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 arrangement of LEDs, the SMC6824MPE 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 SMC6824MPE 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 shared Small Form Factor Pluggable (SFP) transceiver slots. If an SFP transceiver (purchased separately) is installed in a slot and has a valid link on the port, 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-4.)

Note: Neither the 1000BASE-T RJ-45 ports nor the SFP slots 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. And, 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 maximum distance between end stations is limited. For Ethernet, there may be up to four hubs between any pair of stations and for Fast Ethernet, the maximum is two. This is known as the 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 SMC6824MPE PoE 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.

Collapsed Backbone

The SMC6824MPE switch is an excellent choice for mixed Ethernet and Fast Ethernet installations where 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 using one of the Gigabit Ethernet ports built into the front panel.

In the figure below, the switch is operating as a collapsed backbone for a small LAN. It is providing dedicated 100 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.

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. A 1000BASE-ZX single-mode fiber (SMF) link can run up to 100 km. This allows the switch to serve as a collapsed backbone, providing direct connectivity for a widespread LAN.

1000BASE-LX or 1000BASE-ZX 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.

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-ZX: 100 km (62.14 miles) using single-mode fiber

However, power budget constraints must also be considered when calculating the maximum cable length for your specific environment.

Selecting a Site

SMC6824MPE 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 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.

Figure 3-7 Connecting Switches in a Stack

Note: The stacking transceiver must only be installed in the port 25 SFP

slot.

To connect up to eight switches in a stack, perform the following steps:

Stack Master

Slave

1. Install SFP stacking transceivers into the port 25 slot for each switch in the stack.

2. Plug one end of a stack cable into the Tx (top) port of the top unit

3. Plug the other end of the stack cable into the Rx (bottom) port of the next unit.

4. Repeat steps 1 and 2 for each unit in the stack. Form a simple chain starting at the Tx port on the top unit and ending at the Rx port on the bottom unit (stacking up to 8 units).

3-9

NSTALLING THE SWITCH

5. Complete the stack connections by plugging one end of a stack cable into the Tx port on the bottom unit and the other end into the Rx port on the top unit.

6. Select the Master unit in the stack by pressing the push button in on only one of the switches. Only one switch in the stack can operate as the Master, all other units operate in slave mode. If more than one switch in the stack is selected as Master, or if no switches are selected, the stack will not function.

Note: The stacking feature requires that all stacking transceiver ports be

connected and the switches powered on. If one stack link is not connected, or if a switch is powered off or fails, the stack will not function. To re-establish the stack all switches in the stack must be powered on (or the faulty switch replaced), and the Master unit rebooted. This will then reboot all the other switches in the stack.

Connecting to a Power Source

To connect a switch to a power source:

1. Insert the power cable plug directly into the AC receptacle located at the back of the switch.

100-240V~ 50-60Hz 7.5A

Figure 3-8 Power Receptacles

2. Plug the other end of the cable into a grounded, 3-pin socket, AC power source.

3-10

ONNECTING TO THE CONSOLE PORT

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.

3. Check the front-panel LEDs as the device is powered on to be sure the PWR LED is lit. If not, check that the power cable is correctly plugged in.

Connecting to the Console Port

The DB-9 serial port on the SMC6824MPE switch’s front panel is used to connect to the switch for out-of-band console configuration. If using a stack, the connection must be made to the serial port of the Master unit in the stack. The on-board menu-driven configuration program can be accessed from a terminal or a PC running a terminal emulation program. The pin assignments used to connect to the serial port are provided in the following table.

ONNECTIONS

Connecting Network Devices

The SMC6824MPE PoE 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 SFP transceivers.

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

Twisted-Pair Devices

Each device requires a twisted-pair (UTP or STP) 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.

Power over Ethernet Connections

The SMC6824MPE 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.

4-1

AKING NETWORK CONNECTIONS

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 SMC6824MPE switch delivers power to a device using the two unused wire pairs in UTP or STP cable (RJ-45 pins 4, 5, 7, and 8). 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.

Cabling Guidelines

The RJ-45 ports on the SMC6824MPE 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.

4-2

WISTED-PAIR DEVICES

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

2. 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.”) Otherwise, attach the other end to an available port on the SMC6824MPE 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.

3. As each connection is made, the Link LED (on the switch) corresponding to each port will light to indicate that the connection is valid.

Today, the punch-down block is an integral part of many of the newer equipment racks. It is actually part of the patch panel. Instructions for 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 SMC6824MPE 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 Devices

An optional slide-in 1000BASE-SX, 1000BASE-LX, or 1000BASE-ZX 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.

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.

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 SMC6824MPE 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.

ABLE LABELING AND CONNECTION RECORDS

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 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.

• If the switch is installed in a rack, check the connections to the punch-down block and patch panel.

• Verify that the proper cable type is used and its length does not exceed specified limits.

• Check the adapter on the attached device and cable connections for possible defects. Replace the defective adapter or cable if necessary.

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.

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-B

In-Band Access

You can access the management agent in the SMC6824MPE 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:

AND ACCESS

• 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

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.

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

specific orientation. (See “Cabling Guidelines” on page 4-2 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 not exceed 100 meters (328 feet).

Data is delivered on the standard two wire pairs (pins 1, 2, 3, and 6), and PoE power is supplied using the two previously spare pairs (pins 4, 5, 7, and 8). 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.

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.

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.

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.

LED

Light emitting diode used for monitoring a device or network condition.

Local Area Network (LAN)

A group of interconnected computer and support devices.

Modal Bandwidth

Bandwidth for multimode fiber is referred to as modal bandwidth because it varies with the modal field (or core diameter) of the fiber. Modal bandwidth is specified in units of MHz per km, which indicates the amount of bandwidth supported by the fiber for a one km distance.

Media Access Control (MAC)

A portion of the networking protocol that governs access to the transmission medium, facilitating the exchange of data between network nodes.

MIB

An acronym for Management Information Base. It is a set of database objects that contains information about the device.

Network Diameter

Wire distance between two end stations in the same collision domain.

RJ-45 Connector

A connector for twisted-pair wiring.

STP

Shielded twisted-pair cable.

Switched Ports

Ports that are on separate collision domains or LAN segments.
