Typical Network Configuration for the SLM2048

When you connect your network devices, make sure you

do not exceed the maximum cabling distances, which are

listed in the following table:

A hub refers to any type of 100 Mbps hub. A 10 Mbps hub connected

to another 10 Mbps hub can span up to 100 meters (328 feet).

Pre-Installation Considerations

Fast Ethernet Considerations

If you are using the Switch for Fast Ethernet (100 Mbps)

applications, you must observe the following guidelines:

Full-Duplex Considerations

The Switch provides full-duplex support for its RJ-45

ports. Full-duplex operation allows data to be sent and

received simultaneously, doubling a port’s potential data

throughput. If you will be using the Switch in full-duplex

mode, the maximum cable length using Category 5 cable

is 328 feet (100 meters).

1000BASE-T Cable Requirements

All Category 5 UTP cables that are used for 100BASE-TX

connections should also work for 1000BASE-T, providing

that all four wire pairs are connected. However, it is

recommended that for all critical connections, or any

new cable installations, Category 5e (enhanced Category

5) or Category 6 cable should be used. The Category

5e specification includes test parameters that are only

recommendations for Category 5. Therefore, the first

step in preparing existing Category 5 cabling for running

1000BASE-T is a simple test of the cable installation to be

sure that it complies with the IEEE 802.3ab standards.

Positioning the Switch

Before you choose a location for the Switch, observe the

following guidelines:

Make sure that the Switch is accessible and that the

cables can be connected easily.
Keep cabling away from sources of electrical noise,

power lines, and fluorescent lighting fixtures.
Position the Switch away from water and moisture

sources.
To ensure adequate air flow around the Switch, be

sure to provide a minimum clearance of two inches

(50 mm).
Do not stack free-standing Switches more than four

units high.

Placement Options

There are two ways to physically install the Switch, either

set the Switch on its four rubber feet for desktop placement

or mount the switch in a standard-sized, 19-inch wide, 1U-

high rack for rack-mount placement.
