Access Point 530. Note that this document describes troubleshooting mostly
from a hardware perspective. You can perform more in-depth troubleshooting
on the Access Point 530 using the software tools available with the access
point, including the full-featured console interface and the built-in Web
browser interface.

Basic Troubleshooting Tips
Most problems are caused by the following situations. Check for these items
first when starting your troubleshooting:
■ Connecting to devices that have a fixed full-duplex configuration.
By default, the RJ-45 port uses auto-negotiation to determine the duplex
mode. That is, when connecting to attached devices, the access point will
operate in one of two ways to determine the link speed and the commu-
nication mode (half duplex or full duplex):
• If the connected device is also configured to use auto-negotiation, the
access point will automatically negotiate both link speed and commu-
nication mode.
• If the connected device has a fixed configuration, for example
100 Mbps, at half or full duplex, the access point will automatically
sense the link speed, but will default to a communication mode of half
duplex.
