4.1.6 Assigning a static IP address to the Wireless AP
Depending upon the network condition, you can assign a static IP address to the
Wireless AP using the HiPath Wireless Assistant (Controller’s GUI). Refer to
Section 4.4.6, “Setting up the Wireless AP using static configuration”, on page
165 for more information.
4.2 Discovery and registration overview
When the Wireless AP is powered on, it automatically begins a discovery process
to determine its own IP address and the IP address of the HiPath Wireless
Controller. When the discovery process is successful, the Wireless AP registers
with the HiPath Wireless Controller.
Warning: Only use power supplies that are recommended by Siemens. For
example, for the Wireless 802.11n AP use Siemens S30122-X8010-X13.
4.2.1 Wireless AP discovery
Wireless APs discover the IP address of a HiPath Wireless Controller using a
sequence of mechanisms that allow for the possible services available on the
enterprise network. The discovery process is successful when the Wireless AP
successfully locates a HiPath Wireless Controller to which it can register.
You must ensure that the appropriate services on your enterprise network are
prepared to support the discovery process. The following five steps summarize
the discovery process:
• Step 1 – Use the IP address of the last successful connection to a HiPath
Wireless Controller.
Once a Wireless AP has successfully registered with a HiPath Wireless
Controller, it recalls that controller's IP address, and uses that address on
subsequent reboots. The Wireless AP bypasses discovery and goes straight
to registration.
If this discovery method fails, it cycles through the remaining steps until
successful.
• Step 2 – Use the predefined static IP addresses for the HiPath Wireless
Controllers on the network (if configured).
