Overview
SMC’s TigerSwitch ™ , SMC6709L2, is an intelligent Layer-2 switch with
8 10/100 Mbps ports, 1 1000BASE-T port, plus two slots for slide-in
100BASE-FX or 1000BASE-X modules. 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.
This switch can easily
tame your network with full support for Spanning Tree
Protocol,
Multicast Switching, and Virtual LANs. It brings order to poorly
performing networks by segregating them into separate broadcast domains
with IEEE 802.1Q compliant VLANs, empowers multimedia applications
with multicast switching and QoS 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
This switch uses store-and-forward switching to ensure maximum data
integrity. In store-and-forward switching mode, 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.
This switch provides a wide range of advanced features. Port-based and
tagged VLANs, plus support for automatic GVRP VLAN registration that
provides 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, refer to the Management Guide.

Description of Hardware
10BASE-T/100BASE-TX Ports
There are eight fixed 10/100BASE-TX RJ-45 ports on the switch. Because
these ports 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.
Each of these ports support auto-negotiation, so the optimum
transmission mode (half or full duplex) and data rate (10/100 Mbps)
can be selected automatically. Each port also supports IEEE 802.3x
auto-negotiation of flow control, so the switch can automatically
prevent port buffers from becoming saturated.
Note: If a device connected to one of these ports does not support
auto-negotiation, the communication mode of that port can be
configured manually.
1000BASE-T Port
There is one fixed 1000BASE-T RJ-45 port on the switch’s front
panel. This port operates at 10, 100 or 1000 Mbps, and supports
auto-negotiation of speed, duplex mode (i.e., half or full duplex), and
flow control.
This port is shared with the Gigabit Module slot on the switch’s rear
panel. If a 1000BASE-X module is installed in the slot and has a
valid link on its port, the 1000BASE-T port is disabled.
Note: If an attached device does not support auto-negotiation, you will
have to manually configure the switch and the other device to
match the duplex mode and speed.

Module Slots
The switch provides two slots for optional media extender modules. The
slot on the front panel, labeled “M1,” supports fiber optic modules with
one 100BASE-FX port. The slot on the rear panel, labeled “M2,” supports
modules with one 1000BASE-X port.
See “Optional Media Extender Modules” on page 1-5 for more details on
the available modules.

Optional Media Extender Modules
Caution: The media expansion modules are not hot-swappable. Be sure
you power off the switch before installing any of these modules.
Optional 1000BASE-SX Module - SMC6709L2GSSC
Figure 1-2. Single-Port 1000BASE-SX Multimode Module
Using multimode 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 full-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).
