Overview
SMC’s TigerSwitch 10/100/1000 (SMC8612T) has 12 10/100/
1000BASE-T ports, four of which are combo ports that are shared with
four Small Form Factor Pluggable (SFP) transceiver slots.

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. This switch also features full-duplex capability on all
ports, which effectively doubles the bandwidth of each connection.

Switching Method
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.
10/100/1000
Management Options
This switch contains a comprehensive array of LEDs for “at-a- glance”
monitoring of network and port status. It also includes a built-in network
management agent that allows the switch to be managed in-band using
SNMP or RMON (Groups 1, 2, 3 and 9) protocols, with a Web browser, or
remotely via Telnet. It provides 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 for configuration and monitoring out-of band via a null-modem
cable. (See Appendix B: for wiring options.)
This switch provides a wide range of advanced performance-enhancing
features. Port-based and tagged VLANs, plus support for automatic
GVRP VLAN registration and IGMP multicast filtering, providing traffic
security and efficient use of network bandwidth. QoS priority queueing
ensures the minimum delay for moving real-time multimedia data across
the network. Flow control eliminates the loss of packets due to bottlenecks
caused by port saturation. Broadcast storm control prevents broadcast
traffic storms from engulfing the network. For a detailed description of the
advanced features, refer to the Management Guide.

ESCRIPTION OF HARDWARE
Description of Hardware
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-3.)
Each of these ports support auto-negotiation, so the optimum
transmission mode (half or full duplex), and data rate (10, 100, 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 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
four of the RJ-45 ports (Ports 9~12). 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.

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; 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.
2
A switch can be easily configured in any Ethernet network to significantly
boost bandwidth while using conventional cabling and network cards.

Application Examples
The TigerSwitch 10/100/1000 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
This switch is an excellent choice for mixed Ethernet, Fast Ethernet or
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 for up to 12 workstations or servers. When the
time comes for further network expansion, you can easily build on this
basic configuration by adding Fast Ethernet or Gigabit Ethernet links
directly to one or more workgroup switches.
In the figure below, this switch is operating as a collapsed backbone for a
small LAN. It is providing dedicated 20 Mbps full-duplex connections to
workstations, 200 Mbps full-duplex connections to power users, and
2 Gbps full-duplex connections to servers.

With 12 parallel bridging ports (i.e., 12 distinct collision domains), this
switch can collapse a complex network down into a single efficient bridged
node, increasing overall bandwidth and throughput.
In the figure below, the 1000BASE-T RJ-45 ports on the switch are
providing 2 Gbps full-duplex connections for up to 12 local segments. In
addition, the switch is also connecting remote servers over fiber optic

Remote Connection with Fiber Cable
Fiber optic technology allows for longer cabling than any other media type.
A 1000BASE-LX SFP transceiver link can connect to a site up to 5 km
away. This allows the Gigabit Ethernet switch to serve as a collapsed
backbone, providing direct connectivity for a widespread LAN. A Gigabit
SFP transceiver can also be used for a high-speed connection between
floors in the same building, or to connect to other buildings in a campus
setting. The figure below illustrates a Gigabit Ethernet switch connecting
multiple segments with fiber cable..

Making VLAN Connections
VLANs can be based on port groups, or each data frame can be explicitly
tagged to identify the VLAN group it belongs to. When using port-based
VLANs, ports can be assigned to one or more groups. Port-based VLANs
are suitable for small networks. A single switch can be easily configured to
support several VLAN groups for various organizational entities (such as
Finance and Marketing).
When you expand port-based VLANs across several switches, you need to
make a separate connection for each VLAN group. This approach is,
however, inconsistent with the Spanning Tree Protocol, which can easily
segregate ports that belong to the same VLAN. When VLANs cross
separate switches, you need to use VLAN tagging. This allows you to
assign multiple VLAN groups to the “trunk” ports (that is, tagged ports)
connecting different switches.

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. For network applications that require routing between dissimilar
network types, you can attach this switch directly to a router.
4. As a general rule the length of Gigabit fiber optic cable for a single
switched link should not exceed 550 m (1805 ft) for 1000BASE-SX
multimode fiber or 5 km (16404 ft) for 1000BASE-LX single-mode
fiber.
However, power budget constraints must also be considered when
calculating the maximum cable length for your specific environment.

Note: 1. When connected to a shared collision domain (such as a hub
with multiple workstations), switch ports must be set to
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

Fiber Optic Devices
A Small Form-Factor Pluggable (SFP) transceiver (1000BASE-SX,
1000BASE-LX or 1000BASE-LH) may also be used for backbone and
long distance connections.
Multimode fiber optic ports require 50/125 or 62.5/125 micron
multimode fiber optic cabling with an LC connectors (for SFPs) at both
ends. Single-mode fiber ports require 9/125 micron single-mode fiber
optic cable with an LC connectors (for SFPs) at both ends.
Caution: Fiber optic SPF transceivers use lasers to transmit signals over
fiber optic cable. You should never look directly at a transmit
port when it is powered on.
1. 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.
2. 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.
3. As a connection is made, check the green Link LED on the switch

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 such as EliteView. 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.

Twisted-Pair Cable and Pin Assignments
Caution: DO NOT plug a phone jack connector into any RJ-45 port.
Use only twisted-pair cables with RJ-45 connectors that
conform with FCC standards.
For 1000BASE-T connections, a twisted-pair cable must have four pairs of
wires. Each wire pair is identified by two different colors. For example, one
wire might be red and the other, red 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.

1000BASE-T Pin Assignments
1000BASE-T ports switch 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 to 8
at one end of the cable are connected straight through to pins 1 to 8 at the
other end of the cable.
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 or 5e unshielded twisted-pair (UTP) or shielded
twisted-pair (STP) cable for 1000BASE-T connections. Also be sure that
the length of any twisted-pair connection does not exceed 100 meters
(328 feet).

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
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: When testing your cable installation, be sure to include all patch
cables between switches and end devices.
Adjusting Existing Category 5 Cabling
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 6 cables.
2. Reduce the number of connectors used in the link.
3. Reconnect some of the connectors in the link.
