Chapter 3 Troubleshooting 1250 Series Autonomous Access Points
Running the Carrier Busy Test
Step 5 If you are using a power injector with a Cisco switch, choose one of these Power setting options (see
Figure 3-3):
a. If your Cisco switch supports Intelligent Power Management negotiations, uncheck Installed on
Port with MAC address.
b. If your Cisco switch does not support Intelligent Power Management, check Installed on Port with
MAC address and ensure the MAC address for your switch port is displayed in the MAC address
field. The HHHH.HHHH.HHHH indicates the MAC address contains 12 hexadecimal digits.
Note The MAC address field is not case-sensitive.
Step 6 Click Apply and a message displays indicating that you should disable pop-up blockers before
proceeding.
Step 7 Click OK to continue. Your access point reboots and your power settings are configured in the access
point.
Note You might have to refresh your browser page to obtain the latest browser page that indicates your
radios are enabled.
Running the Carrier Busy Test
You can use the carrier busy test to determine the least congested channel for a radio interface (2.4-GHz
or 5-GHz radio module). You should typically run the test several times over several days to obtain the
best results and to avoid temporary activity spikes.
Note The carrier busy test is primarily used for single access points or bridge environments. For sites with
multiple access points, a site survey is typically performed to determine the best operation location and
operating frequency for the access points.
Note All associated clients on the selected radio will be deassociated during the 6 to 8 seconds needed for the
carrier busy test.
Follow these steps to activate the carrier busy test:
Step 1 Use your web browser to access the access point browser interface.
Step 2 At the prompt, enter the administrator username and password. The default username is Cisco and the
default password is Cisco. The username and password are case sensitive.
