Underwriters Laboratories Compliance Statement
Important! Before making connections, make sure you have the correct cord set.
Check it (read the label on the cable) against the following:
The unit automatically matches the connected input voltage. Therefore, no additional
adjustments are necessary when connecting it to any input voltage within the range
marked on the rear panel.
When using a fiber optic port, never look at the transmit laser
while it is powered on. Also, never look directly at the fiber TX
port and fiber cable ends when they are powered on.
Ne regardez jamais le laser tant qu’il est sous tension. Ne
regardez jamais directement le port TX (Transmission) à fibres

Overview
SMC’s TigerSwitch™10/100 is a Fast Ethernet switch with 24
10BASE-T/100BASE-TX ports, plus two slots for optional slide-in
100BASE-FX or Gigabit 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.

Switch Architecture
The TigerSwitch is perfect for moving workgroups from
conventional 10 Mbps Ethernet to multiple-segment 100 Mbps Fast
Ethernet. This switch delivers dedicated 100 Mbps links to each
attached LAN segment (independent collision domain) or to any
PC attached directly to the switch, all with conventional cabling
and adapters. It completely eliminates the bottlenecks of shared
10 Mbps Ethernet networks by providing a wide bandwidth of up
to 8.8 Gbps. This makes it ideal for increasing the throughput of
interconnected Ethernet and Fast Ethernet hubs or server farms.
This switch includes two slots on the rear panel for optional
100BASE-FX or Gigabit modules. The 100BASE-FX module can be
used for backbone and remote connections. The Gigabit modules
can be used to uplink to a collapsed Gigabit backbone or for a
high-speed server 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 management agent that allows the switch 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 front panel for out-of-band
management.

Description of Hardware
Ethernet Ports
The base unit contains 24 10BASE-T / 100BASE-TX ports. It also
has two slots on the rear panel for optional 100BASE-FX or Gigabit
uplink modules. The 100BASE-FX modules have one single-mode
(SC-type) or multimode (SC-type) port. The Gigabit modules have
one 1000BASE-SX (SC-type), 1000BASE-LX (SC-type), or
1000BASE-T (RJ-45) port.
All RJ-45 ports on the base unit operate at 10 or 100 Mbps, and
support auto-negotiation of speed, duplex mode (i.e., half or full
duplex), and flow control. The RJ-45 ports also feature automatic
MDI/MDI-X operation, so you can use straight-through cables for
all connections. The 100BASE-FX modules operate at 100 Mbps,
full duplex. The 1000BASE-SX, 1000BASE-LX and 1000BASE-T
modules operate at 1 Gbps, full duplex. All modules support
auto-negotiation for flow control. Note that when using
auto-negotiation, the speed, transmission mode and flow control
can be automatically set if this feature is also supported by the
attached device. Otherwise, these items can be manually
configured for any connection.
The base unit also includes a display panel for key system and
port indications that simplify installation and network
troubleshooting.
