Welcome

1

Thank you for choosing the Cisco Small Business 300 Series Managed
Switch, a Cisco Small Business network communications device. This
device is designed to be operational right out of the box as a standard
bridge. In the default configuration, it will forward packets between
connecting devices after power up.

Before you begin installing the switch, make sure you have all of the
package contents available, access to the

Series Managed Switch Administration Guide

browser for using web-based system management tools.

Mounting the Cisco Switch

There are three ways to physically install the switch:

• Set the switch on a flat surface.

• Mount the switch on a wall (8-port devices only).

• Mount the switch in a standard rack (1 rack unit high).

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).

2 300 Series Managed Switches

OTE Some switches have a higher temperature rating. The SG300-

N

10SFP, SG300-52P and SG300-52MP are rated at 113 degrees
Fahrenheit (45 degrees Centigrade), and the SG300-28MP, and SF300­24MP are rated at 122 degrees Fahrenheit (50 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 prevent it from sliding or shifting out of position.

Circuit Overloading—Adding the device to the power outlet must not
overload that circuit.

Rack-Mount Placement

STEP 1 Remove the four screws from each side near the front of the switch.

Retain the screws for re-installation. (Do not remove the four screws
from each side near the back of the switch.)

STEP 2 Place one of the supplied spacers on the side of the switch so the

four holes of the spacers align to the screw holes. Place a rack
mount bracket next to the spacer and reinstall the four screws
removed in Step 1.

NOTE If your screws are not long enough to reattach the bracket with

the spacer in place, attach the bracket directly to the case without the
spacer.

STEP 3 Repeat Step 2 for the other side of the switch.

STEP 4 After the mounting hardware has been securely attached, the

switch is now ready to be installed into a standard 19-inch rack.

CAUTION For stability, load the rack from the bottom to the top, with the

heaviest devices on the bottom. A top-heavy rack is likely to
be unstable and may tip over.

Wall Mounting

Only the 8-port models of the switch can be wall-mounted.

NOTE The switch should be mounted so that the ports face up or down.

Do not mount the switch with the ports to the side.

There is a wall-mount kit packed with your switch. The dimensions for the
mount kit are as follows:

1 8 mm/0.4 in 2 22.2 mm/0.9 in 3 6.8 mm/0.3 in 4 17.6 mm/0.7 in

Mount the managed switch to the wall by drilling two pilot holes

3.7 inches (95 mm) apart, attaching the provided anchors and screws to
the wall, then sliding the switch into position on the screws.

The switch should have a minimum of 5 inches (130 mm) of clearance on all
sides.

WARNING Insecure mounting may damage the device or cause injury.

Cisco is not responsible for damages incurred by insecure wall­mounting.

Connecting Network Devices

2

To connect the switch to the network:

STEP 1 Connect the Ethernet cable to the Ethernet port of a computer,

printer, network storage, or other network device.

STEP 2 Connect the other end of the network Ethernet cable to one of the

numbered managed switch Ethernet ports.

The Ethernet port light turns green when the connection is active.
Refer to Features of the Cisco Small Business 300 Series

Managed Switch, page12 for details about the different ports

and LEDs on each switch.

STEP 3 Repeat Step 1 and Step 2 for each device you want to connect to

the managed switch.

NOTE Cisco strongly recommends using Cat5 or better cable for Gigabit

connectivity. When you connect your network devices, do not exceed
the maximum cabling distance of 100 meters (328 feet). It can take up to
one minute for attached devices or the LAN to be operational after it is
connected. This is normal behavior.
