Troubleshooting
This chapter describes how to troubleshoot your ProCurve Wireless 
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. 
This chapter describes the following:
basic troubleshooting tips (page 5-1)
diagnosing with the LEDs (page 5-3)
proactive networking tools (page 5-6)
hardware diagnostic tests (page 5-7)
restoring customer and factory default configurations (page 5-9)

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.
