♦ Power Indicator

This LED lights green when the Switch is receiving power; otherwise, it

♦ 100M Indicator

This LED lights green when the port is operating at 100Mbps. If the

port is operating at 10Mbps, the speed indicator remains dark.

♦ Link/Act Indicator

This LED lights green when the port is connected to a powered-on

Ethernet/Fast Ethernet station. It blinks off briefly when information
is transmitted or received on the port. Please note that when the BNC
module is connected, the Link LED is not lit.

♦ FDX/Col Indicator

This LED lights green when the port is operating in 10/100BASE-T
full-duplex mode. When the Switch is not in full-duplex mode, the
indicator remains dark. If there is data collision on the segment
connected to the respective port, the indicator briefly blinks amber.
Packet collisions are not uncommon, and occur when two or more
devices attempt to transmit data simultaneously on a network. When a
collision occurs, devices pause then re-transmit after a somewhat
random wait period. Because wait periods vary among devices,
successive collisions become increasingly improbable.

If the port connects to another switch or hub, collision indicators of
these devices would indicate the same collision, since collisions span an
entire local area network.

The BNC port module also provides an additional LED indicator for
reporting on the status of the ports. For information about these
indicators, see Appendix C,

Port Module Installation

The Switch supports various slide-in port modules which can be installed
into the slots to provide interface to different network media like twisted­pair, thin coaxial cable, and fiber-optic cable. Four slide-in port modules are
available for use with the Switch: DES-108FL, DES-108FX, DES-108TX,
and DES-108C providing ST, SC, RJ-45, and BNC connectors, respectively.
Each module comes with two switched ports, thus allowing maximum port
configuration of eight switched ports.

Follow these steps to install a module,

Turn off the system (if already on), and unplug it from the power

outlet.
Choose a slot to install the module. When choosing a slot, take into

2.

consideration the nodes you intend to connect to the module’s ports.
Remove the coverplate or module (if there is one installed) from the

3.

selected slot. Use the provided hex screwdriver to loosen and remove
the screws. Set aside these screws.

Align the module with the railings on the slot, and then push the

4.

module all the way in until it locks into place.
Secure the module on the slot with t he screws you re move d in step 3.

5.

Use the same screwdriver to tighten the screws.

Connecting Power

The Switch features a power supply unit that automatically adjusts to the
level of the input voltage. Supported voltage levels range from 100V to
240V AC at 50 to 60 Hz. Your local voltage level should fall within this
range.

14 Installation

DES-1008M User’s Guide

To turn on the Switch, plug in the provided AC power cord into the power
connector at the rear of the system, then slide the rocker power switch to the
“ 1” position. After turning on the power, the Power indicator on the front
panel turns on.

It is not necessary to turn off the system when connecting or disconnecting
cables; this applies to all types of connections. However, when installing,
removing, or replacing system components, the power must be shut off.

Replacing the Fuse

A 1.5A fuse protects the system’s power supply unit from power surges. In
case of power surge, the system fuse will be blown out, thus cutting off the
connection and preventing high voltages from reaching the power supply or
the other sensitive parts of the device. The fuse, plus a spare one, are
contained in a fuse case located just beneath the AC power connector.
When replacement becomes necessary, pry open this case with a small flat­bladed screwdriver and replace the damaged fuse. You may also purchase a
new 1.5A fuse, which is readily available in most local stores.

Network Design Notes

When adding a Switch into your network, take into consideration the
information provided in this section.

Node Connections

There are some Ethernet switches that only support a single dedicated
station per port. This prevents network designers from interconnecting
shared-media hubs using this type of switches. The Switch supports
connections to various types of nodes including workstations, repeaters, and
switches, providing network designers a vast range of comprehensive and
scaleable switched networking solution.

Cable Limitations

When connecting network devices to the Switch, you must observe some
rules on the allowable segment length and cable type to maintain networks
within the set specifications. The table below lists the allowable segment

Making Twisted-Pair
Attachments

You can make twisted-pair attachments to the Switch by first installing
DES-108TX modules. The system can be configured to have a maximum of
eight switched twisted-pair ports. Each of these ports support N-Way or
100Mbps full-duplex force mode.

Depending on the node you are connecting to a twisted-pair port, you will
need either a straight or crossover twisted-pair cable. For connection to a
hub, you will need a crossover twisted-pair cable; for connection to other
network devices such as servers and switches, you will need a crossover
cable. A crossover cable is almost the same as an ordinary twisted-pair
cable only that the pin configuration of a crossover cable is crossed over.
Maximum cable length is 100 meters.

For information on cable pin configuration, see Appendix B,

Making Thin Coaxial
Attachments

You can make BNC attachments to the Switch by first installing DES-108C
modules. The system can be configured to have a maximum of eight
switched BNC ports. You will need a T-connector and thin coaxial cable to
make a BNC link; a 50-ohm BNC terminator is not necessary since each
BNC port can be terminated via the on-board DIP switches. Maximum total
cable length is 185 meters.

NOTES:

You do not need to turn off the Switch when
making network connections; just plug in the
cables into the ports .

When terminating a port, use either the on­board termination or a 50-ohm BNC
terminator. DO NOT use both as this will
cause network error s .

Making Fiber Attachments

If the node you intend to connect is located at a remote area, you may use
fiber optics to link this device to the Switch. Fiber attachment to the system
is available through both the DES-108FL and DES-108FX modules. These
modules come with two switched fiber-optic ports, providing fiber links to
remote nodes.

Each fiber-optic port on these two modules comes with two connectors; one
for reception (Rx) and the other for transmission (Tx). They come with
protective covers to protect the lens inside the connectors from dust, which
could alter the intensity of light coming in and out of the port. Do not
remove these protective covers unless you are ready to connect the port.

You will need a 62.5/125 µm
cable can be up to 2 km l ong.

DES-108C

This module provides two switched BNC ports for connection to thin
coaxial segments. Each port can be terminated without the use of an
external 50-ohm BNC terminator, via the on-board DIP switches. To enable
the port’s termination, slide its respective DIP switch to the ON position.

This module also provides LED indicators for displaying the termination
status for the ports. This indicator turns on when the port’s termination is
enabled; otherwise, it i s off.

DES-108FL

This Fiber-Optic Inter-Repeater Link (FOIRL) module provides two
switched fiber-optic ports for creating fiber-optic links. Each of these ports
has two connectors; one for reception (Rx) and another for transmission
(Tx). When creating a link, ensure that the Rx connectors connect to the Tx
connectors, and vice versa.

Each connector comes with a protective cover to prevent dust from
accumulating inside the connector. Do not remove this cover unless you are
ready to connect the port--too much dust may alter the intensity of light
coming in and out of the port, which could lead to data interpretation errors.

DES-108FX

This module provides two switched fiber-optic ports for creating fiber-optic
links. Each of these ports has two-in-one connectors. Set the module to full­duplex or half-duplex mode by the jumpers on the back panel (see
instructions and diagram on t he next pa ge).

Slide-in Port Modules 33

DES-1008M User’s Guide

To set a port to full- or half-duplex mode, first power down the device. For
half-duplex mode on port 1, use a minijumper to interconnect pins 1 and 4
of jumper pad JP1 (this is the factory default setting). For half-duplex mode
on port 2, use a minijumper to interconnect pins 2 and 3 of JP1.

For full-duplex mode on port 1, disconnect the minijumper from pins 1 and
4 of JP1, and for full-duplex mode on port 2, disconnect the minijumper
from pins 2 and 3 of JP1.

Each connector comes with a protective cover to prevent dust from
accumulating inside the connector. Do not remove this cover unless you are
ready to connect the port. Note that too much dust may alter the intensity of
light coming in and out of the port, which could lead to data interpretation
errors.
