One AC power adapter for the unit
2.2 Checking AC Power
Before you begin 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:

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
eithera10BASE-Tor100BASE-TXdevice. TheRJ-45connectors arefixed
MDI-X jacks which are designed with internal crossover function. It allows
a connection to an end station using straight-through UTP cable.
One 100BASE-FX fiber switched port
This fiber port comes with one fiber connector. For ST and SC
connectors, the contact labeled TX is used for transmission and
the other one labeled RX is used for reception. One duplex mode
selector is located on the rear panel. Either full duplex or half duplex
mode can be selected (factory default: full-duplex).

3.2 UTP Cable
When making a connection to another device using straight-through
UTP cable, 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 cable:
It is suggested to use straight-through UTP cables for all UTP connec-
tions. The maximum length and UTP cable 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 capable 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 capability to auto-sense the connection speed.
The following table 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.

*3 speed is determined by auto-sensing function
Most of 10BASE-T hubs and 100BASE-TX hubs are non-auto-negotia-
tion devices and operate on half-duplex mode.
The operating mode of the fiber port is determined by the setting of
duplex mode selector located on rear panel. The following table lists the
maximum MM fiber cable length connecting to different devices:
