Cisco SG100D-08 Unmanaged Gigabit Switch Quick Start Guide 2

Welcome

Thank you for choosing the Cisco SG 100D-08 Unmanaged Switch, a

Cisco Small Business network communications device.

This guide will familiarize you with the layout of the unmanaged switch and

describe how to deploy the device in your network. For additional

information, see www.cisco.com/smb.

Network Speed and Auto MDI/MDI-X Detection

All ports support network speed auto-negotiation and auto MDI/MDI-X

crossover detection. Network speed auto-negotiation automatically

selects the best connection speed and mode (half- or full-duplex) for

communicating with attached devices. Auto MDI/MDI-X crossover

detection automatically adjusts for the cable type (straight-through or

crossover) used to connect the unmanaged switch to other devices.

Green Energy Savings Technology

Green Ethernet Technology saves energy by entering sleep mode on a

Cisco SG 100D-08 port while there is no connection or the device

connected to that switch port is turned off.

Traffic Prioritization

The Cisco SG 100D-08 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, VLAN tagged

frames.) This ensures that time-sensitive traffic gets the highest level of

service.

3 Cisco SG100D-08 Unmanaged Gigabit Switch Quick Start Guide

Before You Begin

Make sure that you have the following equipment:

•Tools for installing the hardware

•Network cables to connect computers, printers, network storage, IP

cameras, or other network devices.

Getting to Know the Cisco

SG 100D-08

This section describes the exterior of the unmanaged switch.

Front Panel 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.

LEDs 1-8—(Green) Each LED lights up when a connection is made through

its corresponding port. The LED flashes when the corresponding port is

active.

Back Panel Ports

The Ethernet ports and the power port are located on the back panel of

the unmanaged switch.

Ethernet Port—The unmanaged switch is equipped with auto-sensing,

Ethernet (802.3) ports used for wired network communications. Auto-

sensing technology enables each port to automatically detect the speed

and duplex settings of the device connected to it, and adjust its speed and

duplex settings to match the settings of the connected device. Each

Ethernet port accepts an RJ-45 connector.

Side Panels

The security slot is where you can attach a Kensington lock to protect the

switch from theft and is located on the right side of the unmanaged switch.

The power switch is located on the left side of the unmanaged switch.

5 Cisco SG100D-08 Unmanaged Gigabit Switch Quick Start Guide

Installing the Cisco

SG 100D-08

The unmanaged switch can be placed on a wall or a flat surface. 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 (40C).

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

Before you begin, you need 2 wallboard screws to mount the unmanaged

switch. We recommend using screws with a minimum of 0.16 inches (4mm)

width at the head and a shaft diameter of at least 0.06 inches (1.5mm).

WARNING Cisco is not responsible for damages incurred by insecure wall-

mounting.

To mount the unmanaged switch to the wall:

STEP 1Determine where you want to mount the unmanaged switch. Verify

that the surface is smooth, flat, dry, and sturdy.

STEP 2Drill two pilot holes into the wall surface.

Cisco SG 100D-08: The screws should be 2.5 in. (63.5 mm) apart.

The wall-mount slots are two crisscross slots on the bottom panel

of the unmanaged switch.

Cisco SG100D-08 Unmanaged Gigabit Switch Quick Start Guide 6

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 switch wall-mount slots over the screws and

slide the unmanaged switch down until the screws fit snugly into

the wall-mount slots.

STEP 5Connect the unmanaged switch to the other devices, as described

in the “Connecting the Equipment” section.

Flat Surface Installation

To deploy the device on a desktop or other flat surface:

STEP 1Place the unmanaged switch on a desktop near an AC power

source.

STEP 2Connect the unmanaged switch to the other devices, as described

in the “Connecting the Equipment” section.

7 Cisco SG100D-08 Unmanaged Gigabit Switch Quick Start Guide

Connecting the Equipment

This section describes the process for connecting the device to the

network.

STEP 1Power down all of the devices you want to connect to the switch.

STEP 2Connect the Ethernet cable to the Ethernet port of a PC, printer,

network storage, or other network device.

NOTE We recommend using Cat5e or better cable. Also, do not

exceed the maximum cabling distance of 328 feet (100 meters)

per segment.

STEP 3Connect the other end of the network Ethernet cable to one of the

numbered unmanaged switch Ethernet ports.

STEP 4Repeat Step 2 and Step 3 for each device you want to connect to

the unmanaged switch.

CAUTION Make sure you use the power adapter included with the

switch. Using a different power adapter might damage the

switch.

STEP 5Connect the power adapter to the power port on the back panel of

the unmanaged switch.

STEP 6Power up the devices connected to the switch. The LED of each

active port on the switch lights.

NOTE To prioritize voice or video traffic by using the QoS feature on the

Cisco SG 100D-08, 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.
