When you connect your network devices, make sure you
don't exceed the maximum cabling distances, which are
listed in the following table:

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

Pre-Installation Considerations

Fast Ethernet Considerations

If you are using the Switch for Fast Ethernet (100Mbps)
applications, you must observe the following guidelines:

Connecting the Switch

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 .
