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 andwidth-
intensive applications, this switch device provides significant increase
in performance for your Ethernet and Fast Ethernet network. The switch
comes with high num er of 10/100 Fast Ethernet switched ports, each
capa le of transferring information simultaneously at full wire speed to
control and allocate the network andwidth. It also provides two Gigabit
Ethernet slots for migration to Giga it network smoothly.
The key features of the switch units are:
High Port-count and High Bandwidth : Com ining large num er of 10/
100M ps- ased Fast Ethernet switched ports and two Giga it ports,
the switches deliver a tremendous aggregated andwidth for your net-
work.
Easy Migration : With 10BASE-T, 100BASE-T, 1000BASE-X support,
the switch provides a non-disruptive and smooth migration path from
Ethernet to Fast Ethernet, and even to Giga it Ethernet network.
Easy Installation : With the functions of auto-speed-sensing and
auto-negotiation on each port, the switches support plug-and-play
installation y default which eliminates configuration pro lems.
Network Management : With the uilt-in SNMP and we manage-
ment software agent, the switch provides network management func-
tion for advanced applications. It allows you to control and monitor
the switch remotely from anywhere in the network.

The following figure illustrates the switched ports provided on the front
panel. The switch comes with 24 10/100BASE-TX Fast Ethernet switched
ports and two Giga it Ethernet slots for Giga it Ethernet modules.
The following ta le lists the connectors provided on each network ports:

Gigabit slot1 1000BASE-FX Slot GIGABIT1
Gigabit slot2 1000BASE-FX Slot GIGABIT2

-14-
 10/100BASE-TX Fast Ethernet 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 a 100BASE-TX device.
 MDI-X and MDI 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. MDI RJ-45 connector is
provided for easy uplink via standard straight-through UTP to
other device that supports MDI-X RJ-45 connector. The following
ta le shows the pin assignments of MDI-X and MDI RJ-45
connector respectively:
PIN# MDI-X Jacks MDI Jack
1 Rx+ Tx+
2 Rx- Tx-
3 Tx+ Rx+
6 Tx- Rx-
4,5,7,8 NC NC
 Gigabit Ethernet Slots
Two Giga it Ethernet slots are provided for Giga it connections. Each
can accommodate one Giga it Ethernet module. A variety of optional
modules is availa le for selection. Refer to section 3.3 for more infor-
mation.

-15-
3.2 10/100BASE-TX Fast Ethernet Ports
The switch can support connections to the following devices:
• 10BASE-T or 10/100BASE-TX network cards
• 10BASE-T hub ports
• 100BASE-TX hub ports
• 10/100BASE-TX dual speed hub ports
• 10/100BASE-TX switch ports
Auto-negotiation Ca able
The ports support auto-negotiation function when esta lishing a link
connection with any auto-negotiation capa le device. The connection
speed and duplex mode are determined through the negotiation process
with the connected device.
Auto-s eed-sensing
When connecting to a non-auto-negotiation device, half duplex mode is
used. However, the ports can auto-detect the connection speed.
Manual Configuration
The ports are configured to e ena led for auto-negotiation as factory
default. However, it also can e changed and stick to one of the follow-
ing configurations through network management operation:
10M Half-duplex
10M Full-duplex
100M Half-duplex
100M Full-duplex
Trunking Function
The ports are configured as normal data ports instead of trunking ports
as factory default. In order to support trunking function, any port can e
configured as a trunking port manually through network management
operation. As configured, it is no longer a data port. For more details
a out trunking, refer to section 3.4.

-16-
Flow Control
Half-duplex mode uses ack pressure flow control to prevent the receiv-
ing uffer from eing overrun y data from a source node. Full-duplex
mode uses the 802.3X flow control standard to prevent fast Physical
Ports data traffic from overrunning slow data traffic.
UTP Cable Connections
When making a connection to another device using straight-through
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:
CONNECTEDDEVICE UTP CABLE USED & MAXIMUM LENGTH
10BASE-T device Cat. 3, 4, 5 UTP (100 meters)
100BASE-TX device Cat. 5 UTP (100 meters)

3.3 Gigabit Ethernet Slots
Each Giga it Ethernet slot can accommodate one optional Giga it Ether-
net module for your Giga it connection. The following modules are avail-
a le for selection:
Module Wavelength Connector type Fiber cable
2240-SX 850nm SC Multimode fiber
2240-SXJM 850nm MT-RJ Multimode fiber
Module Fiber cable used Maximum length
2240-SX 50/125µm 500 meters

2240-SXJM 50/125µm 500 meters
2240-SXJM 62.5/125µm 220 meters
Module Outline
The following figure illustrates two examples of Giga it modules. Differ-
ent types of modules are mounted with different fi er connectors.
Gigabit Ethernet Modules (To view)
Auto-negotiation function

-18-
The Giga it Ethernet module supports auto-negotiation although it
only operates on 1000M full-duplex mode. This function makes sure
the system operates with maximum performance when it is connected
to an auto-negotiation capa le Giga it Ethernet device.
Du lex Mode Full duplex
Fiber cable MM 50/125mm, 62.5/125mm recommended
Module Installation
1. Turn off the power to the switch unit.
2. Open the cover of Giga it slot.
3. Insert the module into slot until it is seated properly.
4. Screw the module onto the chassis securely.

-19-
3.4 Making Trunk Connections
Two switch units can e cascaded together through any regular switched
data port on each unit when a port 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. Normal data ports can e configured optionally as trunking
ports through the network management operation.
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 1.6G ps, if 8 trunking ports are used for one trunk.
Refer to the software operation manuals in the supplied CD-ROM for
more information a out how to configure a data port as a trunking port.
The following figure illustrates an example of 4-port trunk connection
etween switch A and switch B. The Port 3, 4, 5 and 6 of switch A are
configured as trunking ports and compose one trunk. The Port 5, 6, 7, and
8 of switch B are configured as trunking ports and compose one trunk.
The aggregated andwidth of the trunk is 800M ps.

-20-
Rules :
1. One switch can e configured to have up to 4 trunks and each trunk
can e composed of up to 8 trunking ports. All port mem ers of one
trunk must locate in same group, either in group [port 1-port 12] or in
group [port 13 - port 24].
2. One trunking port can only elong to one trunk.
3. Only one trunk can exist etween two switch units.
4. Crossover UTP ca les should e used at the same time for one trunk
connection. The length of each ca le can e up to 100 meters.
5. When the switched data ports are ena led as trunking ports, they
can only serve trunking function, ut no other data function.
6. Since the trunking is proprietary, the switches do not support trunk
connection to other rands switches.
The following figure illustrates a typical example of trunk connections
etween more than two switch units. Each trunk is a 2-port trunk.
There are four trunks existing in this example. Each has 400M ps and-
width. The top switch is configured to have four trunks and is cascaded
to four lower switch units.
