8 AP Communication Troubleshooting
Before you leave the installation site, contact your network operations center (NOC) to verify
that the AP is online and successfully communicating. If remote communication with the AP is
not possible, perform the following steps:
24. Manually configure the following on a laptop:
 The IP address of the Ethernet port
 Netmask setting
 The Default Router setting
25. Unplug the backhaul connector from the data port of the PoE and connect the laptop to
that port.
26. Verify that you can locally log in to the AP as described in section 7.2.
 If you can successfully log in, further testing of the backhaul and its configuration is needed.
 If you cannot log in, check the IP setting of your laptop.
 If no problems are found, refer to the Chapter 9: Troubleshooting Guide.
The following figure illustrates a method for detailed on-site debugging of an AP installation.
The Ethernet hub allows the user to “sniff” Ethernet traffic between the backhaul port and the
AP to troubleshoot and resolve any issues.
