Overview

SMC’s TigerStack 10G SMC8724M and SMC8748M are intelligent Layer 2
switches with 24/48 10/100/1000BASE-T ports, four of which are
combination ports* that are shared with four SFP transceiver slots (see
Figure 1-1, Ports 21~24/45~48). On the rear panel there is an extender
module slot and two stacking ports. The extender module slot is not
currently functional. 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.

These switches provide 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

The switches employ 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.

The 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.

These switches include a slot on the rear panel for hot-swappable 10
Gigabit Ethernet modules. (The 10 Gigabit Ethernet modules are not
currently available, but will be supported in the future.)

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
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
SNMP-based network management software.

For a detailed description of both switches’ advanced features, refer to the
Management Guide.

Description of Hardware

10/100/1000BASE-T Ports

These ports are RJ-45 ports that operate at 10 Mbps or 100 Mbps, half or
full duplex, or at 1000 Mbps, full duplex. Because all ports on this switch
support automatic MDI/MDI-X operation, you can use straight-through
cables for all network connections to PCs or servers, or to other switches
or hubs. (See “1000BASE-T Pin Assignments” on page B-4)

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.

SFP Slots

The Small Form Factor Pluggable (SFP) transceiver slots are shared with
four of the RJ-45 ports (ports 21~24 for the SMC8724M and ports 45~48
for the SMC8748M). 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.

Stacking Ports

Each unit includes two stacking ports that provide a 10 Gbps high-speed
serial stack backplane connection. Up to eight SMC8724M or SMC8748M
switches can be connected together using optional stacking cables. Note
that the 24-port and 48-port switches can be mixed in the same stack. The
Stack Master button enables one switch in the stack to be selected as the
Master.

LANNING

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.

2

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 TigerStack 10G 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 TigerStack 10G is an excellent choice for mixed Ethernet, Fast
Ethernet, and Gigabit 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 or a Gigabit Ethernet port on a plug-in SFP transceiver.

In the figure below, the 48-port 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 and 1 Gbps full-duplex connections to servers.

PPLICATION EXAMPLES

Network Aggregation Plan

With 24 or 48 parallel bridging ports (i.e., 24 or 48 distinct collision
domains), either of the switches can collapse a complex network down into
a single efficient bridged node, increasing overall bandwidth and
throughput.

In the figure below, the 10/100/1000BASE-T ports in a stack of 48-port
switches are providing 1000 Mbps connectivity through stackable switches.
In addition, the switches are also connecting several servers at 1000 Mbps.

ETWORK PLANNING

Remote Connections 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 a switch stack 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 three TigerStack 10G switch stacks
interconnecting multiple segments with fiber cable.

PPLICATION EXAMPLES

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.

The 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.

ETWORK PLANNING

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 MMF

• 1000BASE-LX: 5 km (3.1 miles) for SMF

• 1000BASE-ZX: 100 km (62.1 miles) for SMF

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

Selecting a Site

TigerStack 10G 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

3

WITCH

• 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.

NSTALLING THE SWITCH

Ethernet Cabling

To ensure proper operation when installing the switches into a network,
make sure that the current cables are suitable for 10BASE-T,
100BASE-TX or 1000BASE-T operation. Check the following criteria
against the current installation of your network:

◆ Cable type: Unshielded twisted pair (UTP) or shielded twisted pair
(STP) cables with RJ-45 connectors; Category 3 or better for
10BASE-T, Category 5 or better for 100BASE-TX, and Category 5e, 6
or better for 1000BASE-T.

◆ Protection from radio frequency interference emissions

◆ Electrical surge suppression

◆ Separation of electrical wires (switch related or other) and

electromagnetic fields from data based network wiring

◆ Safe connections with no damaged cables, connectors or shields

following:

OUNTING

1. Consider network and cabling requirements to select an appropriate
SFP transceiver type.

2. Insert the transceiver with the optical connector facing outward and
the slot connector facing down. Note that SFP transceivers are keyed
so they can only be installed in one orientation.

3. Slide the SFP transceiver into the slot until it clicks into place.

Note: SFP transceivers are hot-swappable. The switch does not need to

be powered off before installing or removing a transceiver.
However, always first disconnect the network cable before
removing a transceiver.

Note: SFP transceivers are not provided in the switch package.

Connecting Switches in a Stack

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

1. Plug one end of the stack cable (ordered separately) in the Down
(right) port of the top unit.

2. Plug the other end of the stack cable into the Up (left) port of the next
unit.

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

4. (Optional) To form a wrap-around topology, plug one end of a stack
cable into the Down port on the bottom unit and the other end into
the Up port on the top unit.

ONNECTING SWITCHES IN A STACK

5. 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 system will select the unit with lowest MAC address as the Master.

Stacking Topologies

All units in the stack must be connected via stacking cable. You can
connect units in a simple cascade configuration, connecting Up ports to
Down ports, from the top unit to the bottom unit. Using this “line”
topology, if any link or unit in the stack fails, the stack is split and two
separate segments are formed. The Stack Link LEDs on the units that are
disconnected flash to indicate that the stack link between them is not
functioning (see Table 1-2 “System Status LEDs” on page 1-6).

When a stack link failure occurs, the stack reboots and a Master unit is
selected within each of the two stack segments. The Master unit will be
either the unit with the Master button depressed or the unit with the
lowest MAC address if the Master button is not depressed on any unit.
When the stack reboots and resumes operations, note that the IP address
will be the same for both of the stack segments. To resolve the conflicting
IP addresses, you should manually replace the failed link or unit as soon as
possible. If you are using a wrap-around stack topology, a single point of
failure in the stack will not cause the stack to fail. It would take two or
more points of failure to split the stack.

If the Master unit fails or is powered off, the backup unit will take control
of the stack without any loss of configuration settings. The Slave unit with
the lowest MAC address is selected as the backup unit.

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.

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

4. If you have purchased a Redundant Power Unit, connect it to the
device and to an AC power source now, following the instructions
included with the package.

Connecting Network Devices

The TigerStack 10G units are 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 or better for 100BASE-TX connections, and
Category 3 or better for 10BASE-T connections.

4

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.

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 “Wiring Closet Connections” on
the next page.) Otherwise, attach the other end to an available port on
the switch.

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

4. As each connection is made, the Link LED (on the switch)
corresponding to each port will light green (1000 Mbps) or amber
(10/100 Mbps) 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

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.

Caution: This switch uses lasers to transmit signals over fiber optic

cable. The lasers are compliant with the requirements of a
Class 1 Laser Product and are inherently eye safe in normal
operation. However, you should never look directly at a
transmit port when it is powered on.

1. Remove and keep the LC port’s rubber cover. When not connected to
a fiber cable, the rubber cover should be replaced to protect the optics.

2. Check that the fiber terminators are clean. You can clean the cable
plugs by wiping them gently with a clean tissue or cotton ball
moistened with a little ethanol. Dirty fiber terminators on fiber cables
will impair the quality of the light transmitted through the cable and
lead to degraded performance on the port.

3. Connect one end of the cable to the LC port on the switch and the
other end to the LC port on the other device. Since LC connectors are
keyed, the cable can be attached in only one orientation.

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 802.3 Std 802.3-2002 standards.

AKING NETWORK CONNECTIONS

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.

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-B

In-Band Access

You can access the management agent in the switch from anywhere within
the attached network using Telnet, a Web browser, or other network
management software tools. However, you must first configure the switch
with a valid IP address, subnet mask, and default gateway. If you have
trouble establishing a link to the management agent, check to see if you
have a valid network connection. Then verify that you entered the correct
IP address. Also, be sure the port through which you are connecting to the
switch has not been disabled. If it has not been disabled, then check the
network cabling that runs between your remote location and the switch.

Caution: The management agent can accept up to four simultaneous

Telnet sessions. If the maximum number of sessions already
exists, an additional Telnet connection will not be able to log
into the system.

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 one Stack Master button is pressed in.

• Check that no more than one Stack Master 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.

The switches allow you to configure ring- or line-topology stacking. When
using ring-topology stacking configuration and a switch fails, or a stacking

Twisted-Pair Cable and Pin Assignments

For 10BASE-T/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. (See “Cabling Guidelines” on page 4-1 for
an explanation.)

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.

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.

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 or better cable for 10 Mbps
connections, or 100-ohm Category 5 or better cable for 100 Mbps or
1000 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, so 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.

Note: The “+” and “-” signs represent the polarity of the wires that

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.)

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

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 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

B-4

T

WISTED-PAIR CABLE AND PIN ASSIGNMENTS

1000BASE-T is a simple test of the cable installation to be sure that it
complies with the IEEE 802.3ab standards.

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 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. 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.

for horizontal subsytems 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.
