CHAPTER 1 INTRODUCTION
DES-1200M are multi-speed network devices combining
Ethernet, Fast Ethernet and Gigabit Ethernet capabilities
in a single compact, rack-mountable cabinet. Combining
10Mbps Ethernet, 100Mbps Fast Ethernet and Gigabit
Ethernet interfaces in one unit allows these switches to
unclog existing LANs and provide a path to efficient,
high-speed networking.
DES-1200M is a combination of a 4-slot host cabinet
which accepts more than 15 different media modules. A
maximum configuration of 32 x 10/100Base-TX switched
ports can be achieved using 4 X 8 port 10/100Base-TX
modules. In the same way, a maximum configuration of
32×10/100Base-TX or 8/16/32 ×100Base-FX ports, or 4
x 1000Base-SX/LX can be accommodated in the host
cabling. Any of the above modules can be integrated to
give up to many different configurations.

DEVICE DESCRIPTION, FEATURES AND CAPABILITIES
DES-1200M Front and Rear Panels
This section describes the features on the front and rear panels
of the DES-1200M unit.
Figure 1-2. Front Panel
Figure 1-3. Rear Panel
All LED status indicators are located on the FRONT panel of
the switches. They provide a real-time indication of system and
operational status. The ports for connections to other devices
and networks are also on the front panels, along with the
crossover switches. The following sections provide descriptions
of the LED indicators and ports.

LED Indicators Explanation
The red power indicator is illuminated when power is
Power
Link/Activity
Full Duplex/Col
provided to the switch and the switch is turned in the ON
position.
Green Link/Activity indicators are illuminated when the
switch detects a connection to that port. The indicator
blinks when data is transmitted over the network
connected to that port.
When a port is not connected, the indicator is off.
Red Full Duplex/Col indicators are illuminated when that
port is in full duplex mode. The indicator is off when that
port is in half duplex mode.
When a collision occurs on the network connected to a
port, that Full Duplex/Col indicator blinks.
Green 100Mbps indicators are illuminated when the port is
100Mbps
operating in 100Mbps mode. The indicator is off when the
port is operating in 10Mbps mode.
Power Port
The power port accepts the power plug.
Power Switch
The power switch, located on the rear panel, controls the power supply

DES-128 8 ports 10/100Base-TX Module
Figure 1-4. 8 port 10/100Base-TX Module
When installed into a DES-1200M, the DES-128 provides 8x
10/100Mbps Switch ports which can connect the DES-1200M to
a 10Mbps or 100Mbps hub or end station.
DES-128 8 Ports 10/100Base-TX Module Features
8x 10/100Base-TX N-Way Switch ports.
Conforms to IEEE 802.3 10Base-T and IEEE 802.3u
100Base-TX and IEEE 802.3x Ethernet Standards
Store and forward switch architecture for abnormal packet
filtering
Support for half and full duplex on all ports
Backplane up to 2.4Gbps
5M memory Buffer support
Automatic address learnin g with 4K address entry storage
Filtering and forwarding rate of 14,880~148,800 packets
per second
DIP Switch with Link Mode
The DES-128 8 port 10/100Base-TX module provides dip

If you adjust to auto-negotiation, then the DIP for 100Mbps and
10Mbps is not effective. If you adjust to Full duplex, then the
DIP for 100Mbps and 10Mbps is effective.

LED Indicators
The are 4 LED indicators for one RJ-45 connection port. If there
is no connection to a port, the corresponding LED indicators are
not lit.
LK1000 The LED indicator is green when the Port is linking
with 1000Mbps mode. When the port is operating in
10Mbps/100Mbps mode or not connected, the LED indicator
is not lit.

ACT This LED indicator blinks green when the port is
transmitting or receiving packets. When the device is not
attached, the LED indicator is not lit.
LK100 The LED indicator is green when the Port is linking
with 100Mbps mode. When the port is operating in 10Mbps
mode or not connected, the LED indicator is not lit.
FD The LED indicator is yellow when the port is operating
in Full-duplex mode. When the port is operating in Halfduplex mode, the LED indicator is not lit.

When installed into a DES-1200M , the DES-124F Module
provides 4 x 100Mbps Fast Ethernet fiber ports which can be
used to:
Connect the DES-1200M to the backbone of your network;
that is, to a basement switch, hub or router.
Connector the DES-1200M to a 100Mbps server or end
station.
An ST (or SC) connector provides the link to the multi-mode
fiber cabling and three LEDs show five status of the Module ata glance. A DIP-switch sets the operating mode to half duplex
or full duplex (default).
