1. Pre-Preparation for upgrade LAP1142 :
because LAP1142 cannot obtain an IP address, the console line is connected to the AP , and an error is reported, the log is as follows :
*mar 1 00:00:44.491:%cdp_pd-2-power_low:all radios disabled-negotiatedws-c2960s-48lps-l (34bd.c8bc.5401)
*mar 1 00:00:50.422:%capwap-3-errorlog:not sending discovery request apdoes not having an Ip!!
*mar 1 00:01:00.422:%capwap-3-errorlog:not sending discovery request apdoes not having an Ip!!
2. determine If the AP itself has a problem, not the network cause the address cannot be obtained
2.1 specific practices are as follows :
find it first . Gateway and VLAN of the AP, looking all the way upstream switch connected to the AP to see if the DHCP configuration is correct (gateway, address range,VLAN and option 43 ) and other information
2.2 determine the network configuration is correct, put a PC into the VLAN of the AP, can correctly obtain the IP address of the VLAN where the corresponding AP resides
3.1 laps of the image file :
you can find the latest or most recent version from the official, note is the light system Image of the AP, it is best to find the official system version of the AP and WLC table to ensure compatibility

3.2. ready to operate the documentation, as this is a local upgrade, the IP address of the PC needs to be configured to transmit the image files of the AP.
3.3 upgrade starts,the IP address in AP recovery mode is 10.0.0.1/8, and the local IP is 10.0.0.2/8.
placed in an address segment or a VLAN and shut down the local computer's computer firewall.
Open in The TFTP server is opened on the PC and the image file is placed in the TFTP specified directory
here is the C1140-k9w8-tar.124-23c.ja4.tar:
C1140-k9w8-tar.124-23c.ja4.tar----> C1140-k9w8-tar.default
