1 Unmanaged Desktop Switch
Welcome
Thank you for choosing the Cisco SF 100D-05, SF 100D-08, SF 100D-16,
or SG 100D-08 Unmanaged Desktop Switch, a Cisco Small Business
network communications device.
Green Energy—Efficient Technology
The Cisco SG 100D-08 switch supports Green Energy-efficient
Technology. It can enter sleep mode, turn off unused ports, and adjust
power as needed. This increases energy efficiency to help businesses use
less power and save money.
Traffic Prioritization
Traffic Prioritization delivers Quality of Service (QoS); all received packets
are examined for QoS priority encoding. The switch reads the priority level
and forwards the packet based on that priority level. For example, during
heavy loads voice and video traffic are given priority over data traffic. The
switch is configured to comply with 802.1p tagged frames. This ensures
that time-sensitive traffic gets the highest level of service.
To prioritize voice or video traffic by using the QoS feature on the
unmanaged desktop switch, set flow control to off in the configurations of
the connected devices. Otherwise, flow control might send a pause frame
to the switch, blocking the high-priority QoS packets queued on the port.
On some devices, such as some IP phones and IP cameras, flow control
might not be configurable.
Jumbo Frame Support
The Cisco SG 100D-08 switch supports frames up to 9,000 bytes called
jumbo frames. Jumbo Frame support improves network throughput and
reduces CPU utilization during large file transfers, such as multimedia files,
by allowing larger payloads in each packet.

Mounting the Cisco
Unmanaged Desktop Switch
The unmanaged desktop switch can be placed on a flat surface or
mounted on a wall. Do not deploy the device in a location where any of the
following conditions exist:
High Ambient Temperature—The ambient temperature must not
exceed 104 degrees Fahrenheit (40 degrees Centigrade).
Reduced Air Flow—Both side panels must be unobstructed to prevent
overheating.
Mechanical Overloading—The device should be level, stable, and
secure to avoid it sliding or shifting out of position.
Circuit Overloading—Adding the device to the power outlet must not
overload that circuit.
Wall Mounting
If you plan to mount this switch to a wall, you need 2 wallboard screws to
mount the unmanaged desktop switch to the wall. We recommend using
screws with a minimum of 0.17 inches (4.3 mm) width at the head and at
least 0.55 inches (14.0 mm) long. Depending on your mounting surface, you
might require longer screws or drywall anchors with a minimum of 0.30
inches (7.6 mm) width at the head and at least 0.59 inches (15.0 mm) long.
WARNING Cisco is not responsible for damages incurred by insecure wall-
mounting.
To mount the unmanaged desktop switch to the wall:
STEP 1Determine where you want to mount the unmanaged desktop
switch. Verify that the surface is smooth, flat, dry, and sturdy.
STEP 2Drill two pilot holes into the wall surface. The distance between the
screws should be:
•Cisco SF 100D-05 = 1.70 in (43.0 mm)
•Cisco SF 100D-08, Cisco SF 100D-16, and
Cisco SG 100D-08 = 2.58 in (63.5 mm)

The wall-mount slots are two crisscross slots on the bottom panel
of the unmanaged desktop switch.
STEP 3Insert a screw into each hole, leaving a gap between the surface
and the base of the screw head of at least 0.1 inches (3 mm).
STEP 4Place the unmanaged desktop switch wall-mount slots over the
screws and slide the unmanaged desktop switch down until the
screws fit snugly into the wall-mount slots.
STEP 5Connect the unmanaged desktop switch to the other devices by
following the instructions in Connecting Network Devices.
For additional information, see Where to Go From Here.
Connecting Network Devices
The diagram is an example of a typical network configuration.
To connect network devices (such as gateways or other switches) to your
unmanaged desktop switch you need one suitable Twisted Pair (TP) cable
for each unit. We recommend Category 5 or better cable for Gigabit
connections.

Unmanaged Desktop Switch 4
NOTE If the uplink from one unmanaged, cascaded switch to another is
moved from one port to another port, it can take 30 to 60
seconds for full network operation to resume. This is normal and
expected behavior.
To connect the unmanaged desktop switch to a network device, such
as a printer or workstation:
STEP 1Connect the Ethernet cable (Cat5 or better recommended) to the
Ethernet port of a computer, printer, network storage, or other
network device.
STEP 2Connect the other end of the network Ethernet cable to one of the
numbered unmanaged desktop switch Ethernet ports.
The LED of the port lights if the device connected is active.
STEP 3Repeat Step 1 and Step 2 for each device you want to connect to
the unmanaged desktop switch.
STEP 4Connect the power adapter to the switch and to a power source,
and move the power switch to the on position.
CAUTION Make sure you use the power adapter included with the
switch. Using a different power adapter might damage the
switch.

Features of the Cisco
Unmanaged Desktop Switch
This section describes the features of the unmanaged desktop switch.
LEDs
The LEDs are located on the front panel of the switch.
System LED—(Green) This LED lights up and remains lit when the switch
is powered on. When the LED is off, nothing is cabled to the port. Or there
is a device connected to the port, but there is a problem with the cable or
the connected device.
LINK/ACT LEDs—(Green) Each LED lights up when a connection is made
through its corresponding port. The LED flashes when the corresponding
port is active. When the LED is off, nothing is cabled to the port. Or there is
a device connected to the port, but there is a problem with the cable or the
connected device.
Ports, Lock, and Power Switch
This section describes the ports, lock, and power switch on the
unmanaged desktop switches.

Unmanaged Desktop Switch 6
Ethernet Port—The unmanaged desktop switch is equipped with auto-
sensing, Ethernet (802.3), RJ-45 ports used for wired network
communications.
Power Port—attachment point for the power adapter.
Kensington Lock—a security slot where you can attach a Kensington lock
to protect the switch from theft.
Power Switch—cycles the unmanaged desktop switch on or off.
