If the access point will be connecting to a wired LAN, the access point must be
I
installed close enough to connect to the hub with an Ethernet cable.
Available AC power. See "Electrical Requirements".

The 3Com 11 Mbps Wireless LAN access point 6000 draws power over Category 5
Ethernet cabling using a power brick. Because erratic electrical power can lead to
serious transmission problems and loss of data, 3Com recommends using one of
the following power alternatives.
Preferred: Isolated ground circuit with online, uninterruptable power supply
I
(UPS) that also acts as filter and surge suppressor
Good: Isolated ground circuit with surge suppressor
I
Fair: Dedicated circuit with UPS
I
Acceptable: Dedicated circuit with surge suppressor
I
If you must use a nondedicated circuit, avoid using the following types of devices
on that circuit, because they can affect the reliability of the circuit:
Devices with components intended or known to produce heat (such as space
I
heaters, laser printers, heat guns, or soldering irons)
Single devices drawing more than 20% of the rated value of the circuit
I
Multiple devices drawing a total of more than 60% of the rated circuit value
I
The 3Com 11 Mbps Wireless LAN access point 6000 must be provided with
power 24 hours a day. 3Com recommends that you avoid providing power to the
access point from an energy management system.
Following is a summary of the basic procedure for setting up and running the site
survey tests. For details, see the topics indicated in the steps.
Set up the access point in the first trial location and set up a client in the first
I
work area.
See "Setting up Equipment" on page 23.
Launch the Site Survey tool, configure the site survey, and run the tests from
I
the first work area.
See "Launching the Tool" on page 23, "Configuring the Site Survey" on
page 23, and "Running the Tests" on page 24.
Move the client to the next work area and run the Site Survey tool again.
I
Repeat this step for each work area.
Set up the access point in the next trial location and run the Site Survey tool
I
again from each of the work areas.
Repeat this step for each trial location.
At the end of the testing, use the results from the Site Survey tool to help you
I
decide on the best location for the access point.
Based on the tests, the Site Survey tool lists the locations in descending order
from best to worst. For more information, see "Interpreting Test Results" on
page 24.
