Verifying Access Point Settings

Cisco Wireless IP Phone 7920 Administration Guide for Cisco CallManager Release 4.0 and 4.1
OL-7104-01
Insert a new or fully charged battery in the Cisco Wireless IP Phone that
•
will not start up.
If you are using the battery, try plugging in the external power supply
•
instead.
If, after attempting these solutions, the phone still does not start up, contact a
Cisco technical support representative for additional assistance.
After the Greeting Message displays, if a phone continues to cycle through
messages displaying on the phone screen, the phone is not associating with the
access point properly. The phone cannot successfully start up unless it associates
and authenticates with an access point.
The Cisco Wireless IP Phone 7920 must first authenticate and associate with an
access point before it can obtain an IP address. The phone follows this start up
process with the access point:
Scans for an access point
•
Associates with an access point
•
Authenticates using LEAP
•
Obtains an IP address
•
Check the SSID settings on the access point and on the phone to be sure the SSID
matches.
Check the authentication type settings on the access point and on the phone to be
sure authentication/encryption settings match.
If the message, "No Service - IP Config Failed," DHCP failed because the
Note
encryption between the access point and phone do not match.
