Overview

The SMC6128PL2 is an intelligent PoE switch with 24 10/100BASE-T
ports, two 10/100/1000BASE-T ports and two Gigabit combination

1

ports

that are comprised of a RJ-45 port and an SFP transceiver slot.
There is also an SNMP-based management agent embedded on the main
board. This agent supports both in-band and out-of-band access for
managing the switch.

The switch provides a broad range of powerful features for Layer 2
switching, delivering reliability and consistent performance for your
network traffic. They bring order to poorly performing networks by
segregating them into separate broadcast domains with IEEE 802.1Q
compliant VLANs, and empower multimedia applications with multicast
switching and CoS services.

Switch Architecture

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

These switches use 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.

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 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

These switches contain a comprehensive array of LEDs for “at-a-glance”
monitoring of network and port status. They also include a management
agent that allows you to configure or monitor the switch using its embedded
management software, or via SNMP applications. To manage a switch, you
can make a direct connection to the RS-232 console port (out-of-band), or
you can manage it 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 advanced features, refer to the
SMC6128PL2 Management Guide.

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.

SFP Slots

The Small Form Factor Pluggable (SFP) transceiver slots are shared with two
of the RJ-45 ports. 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.

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 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 Ethernet, Fast Ethernet, or Gigabit
Ethernet network to significantly boost bandwidth while using conventional
cabling and network cards.

Application Examples

The SMC6128PL2 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 in the following pages.

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 a switch port and allow power to be supplied over
the connecting cable. 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 three PoE devices. It is
also providing dedicated 100 Mbps full-duplex data connections to the
devices. In addition, other non-PoE devices can be connected to the switch.

Collapsed Backbone

The SMC6128PL2 is an excellent choice for mixed Ethernet, Fast Ethernet,
and Gigabit Ethernet installations where significant growth is expected in the
near future. In a basic stand-alone configuration, it can provide 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
Fast Ethernet ports built into the front panel or a Gigabit Ethernet port on a
plug-in SFP transceiver.

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 1000 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 Connection with Fiber Cable

Fiber optic technology allows for longer cabling than any other media type. A
1000BASE-SX (MMF) link can connect to a site up to 550 meters away, a
1000BASE-LX (SMF) link up to 5 km, and a 1000BASE-ZX link up to 100
km. This allows the switch to serve as a collapsed backbone, providing direct
connectivity for a widespread LAN.

A 1000BASE-SX SFP transceiver can be used for a high-speed connection
between floors in the same building, a 1000BASE-LX SFP transciever can be
used to connect to other buildings in a campus setting, and a 1000BASE-ZX
SFP transceiver can be used for a long-haul connection to a remote site.

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

Making VLAN Connections

These switches support 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.

These switches also support multiple spanning trees which allow VLAN
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 if 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) for multimode fiber.

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

•1000BASE-ZX: 100 km (62 miles) for single-mode fiber.

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

Selecting a Site

TigerSwitch 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 45 °C (32 to 113 °F) and
its humidity within 10% to 90%, non-condensing

- provide adequate space (approximately two inches) on all sides for
proper air flow

- be accessible for installing, cabling and maintaining the devices

3

- 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 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.

higher than the ambient room temperature, check that the
rack-environment temperature is within the specified operating
temperature range. (See page C-2.)

• Mechanical Loading: Do not place any equipment on top of a
rack-mounted unit.

• Circuit Overloading: Be sure th at the sup ply circuit to the rack assembly

Connecting Network Devices

The SMC6128PL2 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 tranceivers.

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.

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.

WISTED-PAIR DEVICES

Cabling Guidelines

The RJ-45 ports on the switch supports 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 device’s RJ-45

connector.

Figure 4-1 Making Twisted-Pair Connections

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 outlet that is
connected to the wiring closet. (See “Network Wiring Connections”
on page 4.) Otherwise, attach the other end to an available port on the
switch.

4-3

M

AKING NETWORK CONNECTIONS

Make sure each twisted pair cable does not exceed 100 meters (328 ft)
in length.

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.

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.

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 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 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

An optional Gigabit SFP transceiver (1000BASE-SX, 1000BASE-LX, or
1000BASE-ZX) 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 fiber optic
cable 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.

4-5

M

AKING NETWORK CONNECTIONS

Warning: 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 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.

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.

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.

ROUBLESHOOTING

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, 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 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.

Twisted-Pair Cable and Pin Assignments

For 10/100BASE-TX connections, a 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.

Caution: DO NOT plug a phone jack connector into any RJ-45 port.

This will damage the switch. Use only twisted-pair cables with
RJ-45 connectors that conform with FCC standards.

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.

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.

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

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

2. Reduce the number of connectors used in the link.

3. Reconnect some of the connectors in the link.

Bandwidth

The difference between the highest and lowest frequencies available for
network signals. Also synonymous with wire speed, the actual speed of the
data transmission along the cable.

Collision

A condition in which packets transmitted over the cable interfere
other. Their interference makes both signals unintelligible.

Collision Domain

Single CSMA/CD LAN segment.

CSMA/CD

CSMA/CD (Carrier Sense Multiple Access/Collision Detect) is the
