Chapter 1 Product Introduction
This chapter describes the features of the SMCGS1601/SMCGS2401 Switch.
1.1 Product Overview
The SMCGS1601/SMCGS2401 Switch provides you with a high-performance,
low-cost, easy-to-use, seamless and standard upgrade to boost your old network to
1000Mbps. Increase the speed of your network server and backbone connections
make Gigabit a reality. Power users in the home, office, workgroup, or creative
production environment can now move large, bandwidth-intensive files faster.
Transfer graphics, CGI, CAD, or multimedia files and other applications that have
to move large files across the network almost instantly.
The SMC SMCGS1601/SMCGS2401 Switch features a non-blocking switching
architecture that forwards and filters packets at full wire-speed for maximum
throughput, MAC address auto-learning and auto-aging, IEEE802.3x flow control
for full-duplex mode and backpressure for half-duplex mode. It is compatible with
all 10,100 and 1000Mbps Ethernet devices because it is standard-based. It
protects your existing network investments while providing you with a
straightforward migration path to faster Gigabit speeds.
The SMCGS1601/SMCGS2401 Switch is plug-and-play and no configuration is
required. Auto MDI/MDI-X cable detection on all ports eliminate the need for
crossover cable or Uplink port. Each port can be used as general ports or Uplink
ports, and any port can be simply plugged into a server, a hub, a router or a switch,
using the straight cable or crossover cable. Diagnostic LEDs which display link
status and activity, allowing you to quickly detect and correct problems on the
network.

Chapter 2 Identifying External Components
This Chapter describes the front panel, rear panel and LED indicators of the Switch.
SMCGS1601 and SMCGS2401 just differ in the number of LED indicators and
ports and all figures in this guide are of SMCGS2401.
2.1 Front Panel
The front panel of SMCGS2401 consists of switch model, switch LED indicators,
and 24 10/100/1000Mbps RJ-45 ports.
Figure 2-1 SMCGS2401 Switch Front Panel sketch
The LED indicators include Power, Link/Act LED indicators, which are used for
monitoring and pre-troubleshooting of the Switch. The following section shows the
LED indicators of the Switch along with an explanation of each indicator.
¾POWER LED: This indicator will light solid green when the Switch powers up.
If the LED is not lit, please check the power supply and connection.
¾Link/Act LED: The LED indicates Link/Active status. The corresponding LED
indicator will light solid green when connected to a network device. It flashes
green when data is being transmitted or received on the working connection.
¾1000Mbps LED: The corresponding port LED indicator will light solid green
when it's working on 1000Mbps speed. Not lit indicates working on
10/100Mbps speed.
2.2 Rear Panel
The rear panel of SMCGS2401 features a power socket and a Grounding Terminal
(marked with ).
Figure 2-2 SMCGS2401 Switch Rear Panel sketch
¾Grounding Terminal: SMCGS2401 already comes with Lightning Protection
Mechanism. You can also ground the Switch through the PE (Protecting Earth)

4
cable of AC cord or with Ground Cable. For detail information, please refer to
section 3.3 Connect to Ground.
¾AC Power Socket: Connect the female connector of the power cord here, and
the male connector to the AC power outlet. Please make sure the voltage of the
power supply meets the requirement of the input voltage.
Chapter 3 Installation
3.1 Precautions
To ensure a long-term and stable performance of the Switch, please pay attention
to the following before the installation.
1) Safety Requirements
•Before cleaning the Switch, cut off the power supply. Do not clean it by the
waterish cloth, and never use any other liquid cleaning method.
•Take waterproof measures during storage, transportation and operation of
the equipment.
•Use only the power cord provided with the Switch.
•Make sure the voltage of the power supply meets the requirement of the
input voltage of the Switch.
•Do not push any objects into the openings of the Switch.
•Ensure the vent hole is well ventilated and unblocked.
•Do not open or remove the cover of the Switch.
2) Location Requirements
When you choose a location for the Switch, please follow these guidelines:
•Install the Switch on a flat and stable surface that can support the entire
weight of the Switch with all fittings.
•Locate the Switch far from strong electromagnetic field generators (such as
motors), vibration, dust, and direct exposure to sunlight.
•To ensure adequate air flow around the Switch. At least 10 cm (4 inches) of
space at the front and rear of the Switch is needed for ventilation.
•Make sure that the Switch will be accessible and that the cables can be
easily connected.
•Position the Switch away from water and moisture sources, be sure to
provide an acceptable temperature and humidity operating environment.
3.2 Installation
This Switch can be either installed on the standard 19-inch mountable rack or

5
located on the desktop.
Caution:
Please unplug the power cord before installing or removing the Switch.
3.2.1 Desktop Installation
To install the Switch on the desktop, please follow the steps:
1) Set the Switch on a flat surface strong enough to support the entire weight of
the Switch with all fittings.
2) Remove the adhesive backing papers from the rubber feet.
3) Turnover the Switch and attach the supplied rubber feet to the recessed areas
on the bottom at each corner of the Switch.
Figure 3-1 Attaching Rubber Feet
4) Upturn the Switch and connect it to the network devices while keep enough
ventilation space around.
5) Connect the Switch to power source with the provided power cord.
Caution:
Please avoid any heavy thing placed on the Switch.
3.2.2 Rack Installation
To install the Switch in an EIA standard-sized, 19-inch rack, follow the instructions
described below:

6
1) Secure the supplied rack-mounting brackets to each side of the Switch with
supplied screws, as illustrated in the following figure.
Figure 3-2 Attaching Brackets
2) After the brackets are attached to the Switch, use suitable screws (not provided)
to secure the brackets to the rack, as illustrated in the following figure.
Figure 3-3 Mounting Switch
3) Connect the Switch to network devices.
4) Supply power to the Switch with the provided power cord.
3.3 Connect to Ground
Connecting the Switch to ground is to quickly release the lightning over-voltage and

7
over-current of the Switch, which is also a necessary measure to protect the body
from electric shock.
In different environments, the Switch may be grounded differently. The following will
instruct you to connect the Switch to the ground in two ways, connecting to the
Grounding Bar or connecting to the Ground via the power cord. Please connect the
Switch to ground in the optimum way according to your specific operation
environment.
•Connecting to the Grounding Bar
If the Switch is installed in the Equipment Room, where a Grounding Bar is available,
you are recommended to connect the Switch to the Grounding Bar as shown in the
following figure.
Figure 3-4
Note:
The Grounding Bar and Ground Cable are not provided with our product.
•Connecting to the Ground via the power supply
If the Switch is installed in the normal environment, the Switch can be grounded via
the PE（Protecting Earth）cable of the AC power supply as shown in the following
figure.

8
Figure 3-5
* The figure is to illustrate the application and principle. The power plug you get from the package
and the socket in your situation will comply with the regulation in your country, so they may differ
from the figure above.
Note:
If you intend to connect the Switch to the ground via the PE (Protecting Earth)
cable of AC power cord, please make sure the PE (Protecting Earth) cable in the
electrical outlet is well grounded in advance.
3.4 Power on
The SMCGS1601/SMCGS2401 Switch is powered by an AC Power Supply.
Connect the Switch and power outlet by power cord. Powering on the Switch, it will
be automatically initialized and the LED indicators should respond as follows:
1) All of the LED indicators will flash momentarily for one second, which
represents a resetting of the system.
2) The Power LED indicator will light up.
