new products within 30 days of purchase from SMC or its Authorized Reseller. Registration
can be accomplished via the enclosed product registration card or online via the SMC web
site. Failure to register will not affect the standard limited warranty. The Limited Lifetime
warranty covers a product during the Life of that Product, which is defined as the period of
time during which the product is an “Active” SMC product. A product is considered to be
“Active” while it is listed on the current SMC price list. As new technologies emerge, older
technologies become obsolete and SMC will, at its discretion, replace an older product in its
product line with one that incorporates these newer technologies. At that point, the obsolete

FCC - Class A
This equipment generates, uses, and can radiate radio frequency energy and, if not installed
and used in accordance with the instruction manual, may cause interference to radio
communications. It has been tested and found to comply with the limits for a Class A
computing device pursuant to Subpart B of Part 15 of FCC Rules, which are designed to
provide reasonable protection against such interference when operated in a commercial
environment. Operation of this equipment in a residential area is likely to cause interference,
in which case the user, at his own expense, will be required to take whatever measures may be
required to correct the interference. You are cautioned that changes or modifications not
expressly approved by the party responsible for compliance could void your authority to
operate the equipment.
You may use unshielded twisted-pair (UTP) cable for RJ-45 connections—Category 3 or
greater for 10 Mbps connections, Category 5 for 100 Mbps connections and Category 5 or 5e
for 1000 Mbps connections. Use 50/125 or 62.5/125 micron multimode fiber optic cable, or
9/125 micron single-mode cable, for SFP transceiver connections.
Warnings: 1. Wear an anti-static wrist strap or take other suitable measures to prevent
electrostatic discharge when handling this equipment.
2. When connecting this switch to a power outlet, connect the field ground
lead on the tri-pole power plug to a valid earth ground line to prevent elec-
trical hazards.

T IGER S WITCH 10/100
Overview
SMC’s TigerSwitch™ 10/100 is an intelligent Fast Ethernet switch with 48
10BASE-T/100BASE-TX ports and two 10/100/1000BASE-T combo
ports that operate in combination with 2 Small Form Factor Pluggable
(SFP) transceiver slots. This switch can easily tame your network with full
support for Spanning Tree Protocol, Multicast Switching, Virtual LANs,
and Layer 2/3/4 CoS services.

Switch Architecture
The TigerSwitch 10/100 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.
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. The switch 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 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. 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.

O VERVIEW

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, the 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.
VLANs
The TigerSwitch 10/100 supports up to 255 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.
• Provide data security by restricting all traffic to the originating VLAN,
except where a connection is explicitly defined via the switch’s routing
service.

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 Class of Service (CoS) by prioritizing each packet
based on the required level of service, using four distinct queues with
Weighted Round Robin queuing for each port. It uses IEEE 802.1p and
802.1Q tags to prioritize incoming traffic based on input from the
end-station application. Also, the switch provides Layer 3/4 priority
mapping of IP Precedence/DSCP values or IP TCP/UDP port numbers
to the IEEE 802.1p priority tag of each frame. These functions can be
used to provide independent priorities for different types of traffic, such as
delay-sensitive data and best-effort data.
