OVERVIEW
The SMCFS2601 switch provides 24 10/100 Mbps auto-negotiating RJ-45 ports
and 2 10/100/1000 Mbps auto-negotiating RJ-45 ports. Each port on the switch
supports auto MDI/MDI-X, which eliminates the need for crossover cables or
uplink ports. The switch is plug-and-play; any port can be connected to a server,
a hub, or a switch, using straight-through or crossover cable.
FEATURES
◆Complies with IEEE 802.3, IEEE 802.3u, IEEE 802.3ab standards
◆24 ports for 10/100BASE-TX full- and half-duplex connections.
◆2 ports for 10/100 Mbps full/half-duplex and 1000 Mbps full-duplex
connections.
◆Auto-MDI/MDIX on all ports.
◆Auto-negotiation on all ports.
◆Store-and-forward switching eliminates error packets.
◆MAC address learning.
◆Supports IEEE 802.3x flow control for full-duplex mode and back pressure
for half-duplex mode.

IEEE 802.1PQOS
The SMCFS2601 switch supports 802.1p priority queuing Quality of Service,
which is an implementation of the IEEE 802.1p standard. With the 802.1p QoS
function, you can reserve bandwidth for important functions that require a lot of
bandwidth or have a high priority, such as VoIP (Voice-over Internet Protocol),
web browsing applications, or video conferencing. The switch has separate
hardware queues on each physical port to which packets from various
applications are mapped and priorities assigned.
The illustration below shows how 802.1p priority queuing is implemented on the
switch.
Figure 1: Mapping QoS on the Switch
There are two priority queues labeled TC0 and TC1. The untagged packets and
the eight IEEE 802.1p priority values (defined by the standard) are mapped to
the two priority queues on the switch. TC1 has the highest priority of the two
priority queues, while TC0 has the lowest priority.
The SMCFS2601 switch uses Weighted Robin Round (WRR) for scheduling. The
WRR queue-scheduling algorithm schedules all the queues in turn with every
queue assured a certain service time. The default weight values of TC0 and TC1,
are 1:16

RJ-45 PORTS
The switch contains 24 10/100 Mbps RJ-45 ports and 2 10/100/1000 Mbps RJ-
45 ports. All ports support automatic MDI/MDI-X operation, so you can use
straight-through cables for all network connections to PCs or servers, or to other
switches or hubs.
Each of these ports support auto-negotiation, so the optimum transmission
mode (half or full duplex), and data rate (10, 100 or 1000 Mbps) is selected
automatically.
Each port also supports IEEE 802.3x auto-negotiation of flow control, so the
switch can automatically prevent port buffers from becoming saturated.
REAR PANEL
The rear panel of the switch features the AC power socket.

AC POWER SOCKET
Connect the female connector of the power cord to the socket on the switch, and
the male connector to the AC power outlet. Make sure the voltage of the power
supply meets the requirement of the input voltage.
1000M On Green The port is operating at 1000 Mbps.
Off The port is operating at 10 or 100 Mbps.

PRECAUTIONS
To ensure long-term and stable performance of the switch, pay attention to the
following before installation.
SAFETY REQUIREMENTS
◆Before cleaning the switch, disconnect the power supply. Do not clean the
switch using a wet cloth, and never use any other liquid for cleaning.
◆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 holes are well ventilated and unblocked.
◆Do not open or remove the cover of the switch.
LOCATION REQUIREMENTS
When you choose a location for the switch, 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 operating environment that is within the temperature and
humidity specifications.
INSTALLATION
This switch can be either installed in a standard 19-inch mountable rack or
located on a desktop.
DESKTOP INSTALLATION
To install the switch on the desktop, follow these 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. Turn the switch over and attach the supplied rubber feet to the recessed
areas on the bottom at each corner of the switch.
Figure 4: Attaching Rubber Feet
C AUTION : Please unplug the power cord before installing or removing
the switch.

4. Upturn the switch and set in the desired location, making sure there is
enough ventilation space on all sides for proper air flow
5. Connect the switch to a power source with the provided power cord. See
“Powering On” on page 19.
RACK INSTALLATION
To install the switch in an EIA standard-sized, 19-inch rack, follow the
instructions described below:
1. Secure the supplied rack-mounting brackets to each side of the switch with
supplied screws, as illustrated in the following figure.
Figure 5: Attaching Brackets
C AUTION : Avoid placing anything heavy on the switch.

2. Use suitable screws (not provided) to secure the brackets to the rack, as
illustrated in the following figure.
Figure 6: Mounting the Switch
3. Connect the switch to a power source with the provided power cord. See
“Powering On” on page 19.
POWERING ON
The SMCFS2601 switch is powered by connecting to an AC power supply using a
power cord. When powering on the switch, it automatically initializes and the
LED indicators respond as follows:
1. All of the LED indicators flash momentarily for one second, which represents
a resetting of the system.
2. The Power LED indicator turns on green.

C HAPTER 3 | Installing the Switch
Connecting Network Devices
– 20 –
CONNECTING NETWORK DEVICES
The switch is designed to be connected to network cards in PCs and servers, as
well as to other switches and hubs.
CABLING GUIDELINES
The RJ-45 ports on the switch support automatic MDI/MDI-X pinout
configuration, so you can use standard straight-through twisted-pair cables to
connect to any other network device (PCs, servers, switches, routers, or hubs).
Each device requires an unshielded twisted-pair (UTP) cable with RJ-45
connectors at both ends. Use Category 5, 5e or 6 cable for 1000BASE-T
connections, Category 5 or better for 100BASE-TX connections, and Category 3
or better for 10BASE-T connections.
CONNECTING TO PCS, SERVERS, HUBS AND SWITCHES
1. Attach one end of a twisted-pair cable segment to the device’s RJ-45
connector.
2. Attach the other end of the cable segment to an available port on the
switch.
Make sure each twisted pair cable does not exceed 100 meters (328 ft) in
length.
3. As each connection is made, the relevant port LED (on the switch)
corresponding to each port will turn on green to indicate that the connection
is valid.
