Overview
SMC’s TigerSwitch™ 10/100 is a stackable switch with 12 or 24
10BASE-T/100BASE-TX ports, plus two slots for optional slide-in
100BASE-FX or 1000BASE-SX modules. One of these slots can also
be used for an optional stacking module that allows you attach up
to four switches to a 4.8 Gbps high-speed backplane. There is also
an SNMP-based Network Management Module installed in the rear
panel. This module supports both in-band and out-of-band access
for managing the switch and the attached stack. (One module only
must be installed in one switch to manage the stack.)

Switch Architecture
The TigerSwitch employs a high-speed switching fabric. This design
allows for simultaneous transport of multiple packets at low latency
on all ports. It also uses store-and-forward switching to ensure
maximum data integrity. In this mode, the entire packet must be
received into a port buffer and checked for validity before being
forwarded. This prevents errors from being propagated throughout
the network. This switch also features full-duplex capability on all
ports, which effectively doubles the bandwidth of each connection.
This TigerSwitch can be used in a standalone configuration, or can
be stacked up to four high to form a single logical switch with up to
104 ports. When stacked, the 4.8 Gbps stack backplane provides
enough bandwidth for the most demanding environment. Moreover,
you can use a 100 Mbps fiber module for connecting to a remote
site, or a Gigabit module for a high-speed backbone connection.

Management Options
This switch contains a comprehensive array of LEDs for
“at-a-glance” monitoring of network and port status. It also
includes a Network Management Module that allows the entire
stack to be managed in-band via SNMP or RMON (Groups 1, 2, 3
and 9) protocols, with a Web browser, or remotely via Telnet. The
switch also provides a serial port on the rear panel for out-of-band
management.
Note: Only one Network Management Module must be installed
in the stack for the current firmware release.
Description of Hardware
10BASE-T/100BASE-TX Ports (SMC6912M/SMC6924M)
These ports are dual-speed RJ-45 ports with built-in wiring
crossovers (MDI-X). Workstations and servers can be connected to
these ports with straight-through cable. When connecting to
another switch or a hub, you can use straight-through cable to
connect to a port on the attached device that does not have
built-in wiring crossovers (MDI), or use crossover cabling. (See
Appendix B for a pinout description of crossover cable.)
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.

Network Management Module
Figure 1-5. Network Management Module
This switch includes a Network Management Module on the rear
panel. This module can manage the switch and the attached stack.
It offers a variety of management options, including SNMP, RMON
and a Web-based interface. This module also includes an RS-232
port for out-of-band management. This is an RS-232 serial port
with a DB-9 connector. A PC may be connected to this port for
configuration and monitoring purposes out-of band via a fullhandshaking null modem cable. You can also make a remote
connection to this port via modems. This allows you to access the
out-of-band interface. (See Appendix B for a description of wiring
options.)
The Network Management Module provides a wide range of
advanced performance-enhancing features. Multicast filtering
provides support for real-time network applications. Port-based
and tagged VLANs, plus support for automatic GVRP VLAN
registration provide 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. And broadcast storm control prevents broadcast traffic
storms from engulfing the network.
Some of this switch’s advanced features are described below. For a
detailed description, refer to the Management Guide.
Spanning Tree Protocol
The TigerSwitch 10/100 supports IEEE 802.1D Spanning Tree
Protocol. This protocol adds a level of fault tolerance by allowing
two or more redundant connections to be created between a pair
of LAN segments. When there are multiple physical paths between
segments, this protocol will choose a single path and disable all
others to ensure that only one route exists between any two
stations on the network. This prevents the creation of network
loops. However, if the chosen path should fail for any reason, an
alternate path will be activated to maintain the connection.
The default setting for the Spanning Tree Protocol is “enabled.”
This protocol may be configured out-of-band via the serial console
port, or in-band via the Web interface, Telnet, or SNMP network
management software.
10/100
VLANs
The TigerSwitch 10/100 supports up to 256 VLANs. A Virtual LAN
is a collection of network nodes that share the same collision
domain regardless of their physical location or connection point in
the network. By segmenting your network into VLANs, you can:
• Eliminate broadcast storms which severely degrade
performance in a flat network.
• Simplify network management for node changes/moves by
remotely configuring VLAN membership for any port, rather
than having to manually change the node’s IP address.

• Provides data security by restricting all traffic to the originating
VLAN, except where a connection has been configured
between separate VLANs using a router or Layer 3 switch.
Multicast Switching
Specific multicast traffic can be assigned to its own VLAN to ensure
that it does not interfere with normal network traffic and to
guarantee real-time delivery by setting the required priority level
for the designated VLAN. The switch uses IGMP Snooping and
IGMP to manage multicast group registration.
Traffic Priority
This switch provides Quality of Service (QoS) by prioritizing each
packet based on the required level of service, using two distinct
categories with Weighted Fair Queuing. It uses IEEE 802.1p and
802.1Q tags to prioritize incoming traffic based on input from the
end-station application. These functions can be used to provide
independent priorities for delay-sensitive data and best-effort data.
Optional Media Extender Modules

Optional 100BASE-FX Module (SMC6900FSC)
Figure 1-6. 2-Port 100BASE-FX Fiber Module
Using fiber optic cable, the 100BASE-FX port can be connected to
a remote site up to 2 km (1.24 mi.) away. This port operates only
at 100 Mbps, full duplex. This module is fitted with an SC
connector, but you can attach an ST plug to the switch using the
optional SC-ST Converter (Part Number: 99-012034-091).

Optional 1000BASE-SX Module (SMC6900G)
Figure 1-7. Single-Port 1000BASE-SX Gigabit Module
Using fiber optic cable, the 1000BASE-SX port can be connected to
a remote site up to 550 m (1805 ft.) away. The 1000BASE-SX
Gigabit module operates at 1 Gbps, with support for
auto-negotiation of duplex mode and flow control. This module is
fitted with an SC connector, but you can attach an ST plug to the
switch using the SC-ST Converter (Part Number: 99-012034-091).
Optional Stack Module (SMC6900S)
Figure 1-8. Stack Module
10/100
The uplink and downlink stack ports operate at 2 Gbps. These
modules can be used to connect up to four switches to the
backplane. A stack cable is included with each module.
Optional Redundant Power Unit (SMCRPU150W)
SMC provides an optional Redundant Power Unit (RPU),
SMCRPU150W, that can supply power to the switch in the event of
failure of the internal power supply.

Power Supply Receptacles
There are two power receptacles on the rear panel of the switch.
The standard power receptacle is for the AC power cord. The
receptacle labeled “DC Input” is for the optional Redundant Power
Unit (RPU).
