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)

3 Unmanaged Desktop Switch

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.
