Chapter 3 Configuring the Access Point for the First Time
Obtaining and Assigning an IP Address
Obtaining and Assigning an IP Address
To browse to the access point’s Express Setup page, you must either obtain or assign the access point’s
IP address using one of the following methods:
• Connect to the access point console port and assign a static IP address. Follow the steps in the
“Connecting to the Access Point Locally” section on page 3-3 to connect to the console port.
• Use a DHCP server (if available) to automatically assign an IP address. You can find out the
DHCP-assigned IP address using one of the following methods:
– Connect to the access point console port and use the show ip interface brief command to
display the IP address. Follow the steps in the “Connecting to the Access Point Locally” section
on page 3-3 to connect to the console port.
– Provide your organization’s network administrator with your access point’s Media Access
Control (MAC) address. Your network administrator will query the DHCP server using the
MAC address to identify the IP address. The access point’s MAC address is on label attached to
the bottom of the access point.
– Use the Cisco IP Setup Utility (IPSU) to identify the assigned address. You can also use IPSU
to assign an IP address to the access point if it did not receive an IP address from the DHCP
server. IPSU runs on most Microsoft Windows operating systems: Windows 9x, 2000, Me, NT,
and XP.
For information on IPSU, refer to “Using the IP Setup Utility” section on page 3-9.
Connecting to the Access Point Locally
If you need to configure the access point locally (without connecting the access point to a wired LAN),
you can connect a PC to its console port using a DB-9 to RJ-45 serial cable. Follow these steps to open
the CLI by connecting to the access point console port:
Step 1 Connect a nine-pin, female DB-9 to RJ-45 serial cable to the RJ-45 serial port on the access point and
to the COM port on a computer. Figure 3-1 shows the serial port connection.
