2. Installing the Switch
2.1 Unpacking
Check to see that you have everything efore you start the installation.
 Installation guide
 The switch unit
 One AC power adapter for the unit
2.2 Checking AC Power
Before you egin the installation, check the AC voltage of your area. The
AC power adapter which is used to supply the DC power for the unit should
have the AC voltage matching the commercial power voltage in your area.
The specifications of the AC power adapter are:
 AC input power: AC power voltage of your area
 DC output power: +5V VDC 1.2A min.
 DC plug type:

The DC power socket for the AC power adapter is located on the rear of
the switch as shown elow:
2.3 Installing the Switch
1. Install the switch with the AC power adapter provided.
2. Connect the power adapter ca le to the switch efore connecting
the adapter to the AC outlet.

3. Making Network Connections
3.1 Network Switched Ports
There are five ports on the switch for connection to five LAN segments.
Each segment is an independent shared network in one collision-domain.
 Four 10/100BASE-TX switched ports
Each port consists of one RJ-45 connector and is used for connection to
either a 10BASE-T or 100BASE-TX device. The RJ-45 connectors are fixed
MDI-X jacks which are designed with internal crossover function. It allows
a connection to an end station using straight-through UTP ca le.
 One 100BASE-FX fiber switched port
This fi er port comes with one fi er connector. For ST and SC
connectors, the contact la eled TX is used for transmission and
the other one la eled RX is used for reception. One duplex mode
selector is located on the rear panel. Either full duplex or half duplex
mode can e selected (factory default: full-duplex).

The following figure illustrates the front panels with different fi er connectors:
3.2 UTP Cable
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:
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:

3.5 Operating Mode
Four TP ports are designed as auto-negotiation capa le switched ports.
Each port can determine the speed and duplex type used automatically
through an auto-negotiation process with the remote connected auto-ne-
gotiation device. The auto-negotiation process is performed when the con-
nection is made. When connecting to a non-auto-negotiation device, each
TP 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 operating mode includes the
connection speed and duplex type.
Connected Device Operation Mode Used
10BASE-T hub 10Mbps, half-duplex
100BASE-TX hub 100Mbps, half-duplex
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 operating mode of the fi er port is determined y the setting of
duplex mode selector located on rear panel. The following ta le lists the
maximum MM fi er ca le length connecting to different devices:
Connected Device Duplex Mode Distance(MM cable)
Network card Half-duplex 400 m
Network card Full-duplex 2 Km
Class I hub Half-duplex 160 m
2 Class II hubs Half-duplex 112m
Switched fiber port Half-duplex 400 m
Switched fiber port Full-duplex 2Km
