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.

Unpacking
Open the shipping cartons of DES-1200M and carefully
unpacks its contents. The carton should contain the
following items:

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
Power The red power indicator is illuminated when power is
provided to the switch and the switch is turned in the ON
position.
Link/Activity
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.
Full Duplex/Col
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.
100Mbps Green 100Mbps indicators are illuminated when the port is
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
