Typical Network Configuration
When you connect your network devices, make sure you
don't exceed the maximum cabling distance of 100 meters
(328 feet).

Pre-Installation Considerations
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
(50mm).
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 high rack
for rack-mount placement.
