Note
If you purchased a 1242G access point, this quick start guide refers
occasionally to an 802.11a radio. However, your 1242G access point
does not contain an 802.11a radio; it only contains an 802.11b or
802.11g radio. Please disregard the sections in your quick start guide
that refer specifically to an 802.11a radio.
You should review this table and the instructions for opening the top cover.
The table contains important information that you need to know so that you
can successfully configure your access point.

    Note If your access point is connected to inline power, do not connect the power module to the access point. Using two power sources on the access point might cause the access point to shut down to protect internal components and might cause the switch to shut down the port to which the access point is connected.

  • Page 19: Connecting To The Access Point Locally

    – Connect to the access point console port and use a Cisco IOS command to display the IP address, such as show interface bvi1. – Provide your organization’s network administrator with your access point MAC address. Your network administrator will query the DHCP server using the MAC address to identify the IP address.
