1. Introduction
Driven y recent advances in desktop computing technology, todays
network applications have increased in speed, power and the a ility to
process information. To meet the demands of these more powerful appli-
cations, two afforda le switch devices provides significant increase in
performance for your Ethernet or Fast Ethernet network. The switches
come with high num er of switched ports, each capa le of transferring
information simultaneously at full wire speed to control and allocate the
network andwidth.
The key features of the switch units are:
High Port-count and Bandwidth : Com ining large num er of 10/
100M ps- ased Fast Ethernet switched ports, the switches deliver
up to 3.2 G ps or 4.8 G ps aggregated network andwidth for your
Fast Ethernet network
Easy Migration : With 10BASE-T support on each port, the
switches provide a non-disruptive and smooth migration path from
Ethernet to Fast Ethernet network.
Fiber Connectivity : With two optional fi er ports, the switches
support fi er connections to 100BASE-FX devices.
Easy Installation : With the functions of auto-speed-sensing and
auto-negotiation on each port, the switches support plug-and-play
installation which eliminates configuration pro lems.

3. Making Network Connections
3.1 Network Switched Ports
16 switched ports and 24 switched ports are provided on these two
switch models respectively. Each port is equipped with one RJ-45 con-
nector at least. Both models provide one additional uplink RJ-45 connec-
tor on Port 16 and Port 24 respectively. Some switched ports are designed
with trunking function optionally.

 Switched Ports
Each switched port supports one connection to a LAN segments. Each
segment is an independent shared network in one collision-domain.
The connection can e to either a 10BASE-T or 100BASE-TX device.
 MDI-X RJ-45 Connectors
MDI-X jack is la eled [X] normally to indicate the jack is designed
with internal crossover function. It allows a connection to an end
station using straight-through UTP ca le.
 Uplink MDI RJ-45 connectors
One additional MDI RJ-45 connector of each switch is provided for
easy uplink via standard straight-through UTP to other device that
supports MDI-X RJ-45 connector.
 Fiber Slots
Two fi er slots are provided as fi er alternative connection for port 1
and port 3 respectively. Each can accommodate one fi er modules. A
variety of optional fi er modules is availa le for selection. Refer to
section 3.5 for more information.
 Trunking Ports
Some switched ports can e optionally used for supporting trunking
function. This option depends on the trunking configuration DIP SW
W1-W4 setting on rear panel. Refer to section 3.6 for more information.

UTP ca le, make sure MDI-X to MDI connection rule is followed. The
following figure illustrates the pin assignments of a straight-through
UTP and a crossover UTP ca le:
Straight-through and Crossover UTP Cable
It is suggested to use straight-through UTP ca les for all UTP connec-
tions. The maximum length and UTP ca le categories used for the con-
nections to a 10BASE-T device and 100BASE-TX device are:

Swisthed port 1 and port 3 supports two types of connections. One type
is UTP connection through Port 1X and 3X respectively. The other is
fi er connection through slot FX-1 and FX-2 respectively. Both types of
connections can not e used at the same time. Each fi er module pro-
vides optional jumpers to ena le or disa le fi er connection.

3.6 Operating Mode
All TP switched ports are designed as auto-negotiation capa le switched
ports. Each port can determine the speed and duplex type used automati-
cally through an auto-negotiation process with the remote connected
auto-negotiation capa le device. The auto-negotiation process is per-
formed upon the connection is made. When connecting to a non-auto-
negotiation device, each port also features the capa ility to auto-sense
the connection speed. The following ta le lists the operation mode used
for the switched port when it connects to different devices. The operat-
ing mode includes the connection speed and duplex type.
Device Connected Operation Mode Used
Auto-negotiation device Auto-negotiation *2
Non-auto*1 half-duplex device auto-speed-sensing *3, half-duplex
Non-auto full-duplex device Not supported
*1 Non-auto : non-auto-negotiation
*2 determined through auto-negotiation process
*3 speed is determined by auto-sensing function
Most of 10BASE-T hu s and 100BASE-TX hu s are non-auto-negotia-
tion devices and operate on half-duplex mode.
The 100Base-FX fi er module does not support auto-negotiation func-
tion. It operates on 100M ps either full duplex or half duplex type de-
pending on DIP SW W5 and W6 setting. The following ta le lists the
configuration DIP SW W5 W6 setting definitions:
DIP SW Position Definition
W5 Down Port 1X full duplex, FX-1 full duplex
W5 Up Port 1X auto-negotion, FX-1 half duplex
W6 Down Port 3X full duplex, FX-2 full duplex
W6 Up Port 3X auto-negotion, FX-2 half duplex

-15-
3.7 Trunking Support
Two switch units can e cascaded together through any regular switched
port on each unit when an expansion is required. However, the transfer
andwidth etween the two cascaded ports is limited to 200M ps full
duplex. To increase the andwidth for the connection etween two switch
units, a trunking function is implemented on the switch unit for this
purpose. Some ports can e configured optionally as trunking ports.
Two or more trunking ports composes one trunk. Two switch units can
e cascaded through one trunk. The aggregated andwidth of one trunk
can e up to 800M ps, if 4 trunking ports are used for one trunk.
The ports which are equipped with optional trunking function are:
Port 1, Port 2, Port 3, Port 4, Port 9, Port 10, Port 11, Port 12

-16-
The trunking configuration DIP SW W1-W4 is located on the rear panel
and the settings are:
W1 W2 # of Trunks Trunking setting
Down Down 1 4-port trunk Trunk : port 9, 10, 11, 12
Up Down 2 2-port trunks Trunk : port 9, 11, Trunk : port 10, 12
Down Up 1 2-port trunk Trunk : port 9, 11
Up Up No trunk Disable trunking
W3 W4 # of Trunks Trunking setting
Down Down 1 4-port trunk Trunk : port 1, 2, 3, 4
Up Down 2 2-port trunks Trunk : port 1, 3, Trunk : port 2, 4
Down Up 1 2-port trunk Trunk : port 1, 3
Up Up No trunk Disable trunking
Note: Port 1 means either 1X UTP or FX-1 Fiber.
Port 3 means either 3X UTP or FX-2 Fiber.
The following figure illustrates an example of 4-port trunk connection
etween two switches. The aggregated andwidth of the trunk is
800M ps.
