Ideally, the LWAPP access points are plug and play devices. Once you plug a LWAPP AP into a switchport, assuming all the other network config is in place (AP and WLC on same vlan, or AP is able to learn WLC via DHCP or DNS), it should register with the controller just fine.
"sh version" on the AP will have a "k9w8" in it instead of a "k9w7" which stands for autonomous.

Cisco IOS Software, C1130 Software (C1130-K9W8-M), Version 12.4(23c)JZ, RELEASE SOFTWARE (fc1) c1130-k9w8-mx.124-23c.JZ
Autonomous/IOS/Standalone image:

You cannot access the light weight AP via telnet, ssh or web directly. You can only make changes to it via the controller once it registers to it.
It is sometimes necessary to make config changes statically on the AP before it registers to the controller; e.g. assign static address, an ip gateway or tell it which controller to join to. This can be done with cli commands via the console port, which are unlike the IOS commands that we are used to.
1. To see all static config on the AP:
AP0022.9090.e859#sh capwap ip config
LWAPP Static IP Configuration
2. Static config -
AP0022.9090.e859#capwap ap ip address 192.168.1.2 255.255.255.0
AP0022.9090.e859#capwap ap ip default-gateway 192.168.1.1
Telling the AP the controller to join-
AP0022.9090.e859#capwap ap controller ip address 192.168.1.10
AP0022.9090.e859#sh capwap ip config
LWAPP Static IP Configuration

3. To clear the config-
AP0022.9090.e859#clear capwap ap ip address
AP0022.9090.e859#clear capwap ap ip default-gateway
AP0022.9090.e859#clear capwap ap hostname
AP0022.9090.e859#clear capwap ap controller ip address
To clear the AP private config-
AP0022.9090.e859#clear capwap private-config
AP0022.9090.e859#show capwap client config
4. Normally, if the AP cannot find a controller to join, it will automatically reboot.
To prevent it from rebooting,-
AP0022.9090.e859#debug capwap cli no-reload
5. Prior to configuring the AP:
Before the Access Point will allow configuration changes, it is first necessary to enter the following debug command:
AP0022.9090.e859#debug capwap console cli
This command is meant only for debugging/troubleshooting
Any configuration change may result in different
behavior from centralized configuration.
CAPWAP console CLI allow/disallow debugging is on
6.To upgrade the rcv image on the AP-
AP0022.9090.e859#debug capwap console cli
archive download-sw /overwrite /force-reload tftp://<TFTP SERVER>/<file name>
e.g- archive download-sw /overwrite /force-reload tftp://192.168.5.12/ap3g1-rcvk9w8-tar.124-23c.JA3.tar
default password: Cisco
The AP should boot up with the lightweight code; "sh version" on the AP will have a "k9w8" in it instead of a "k9w7" which stands for autonomous.
6. Debug commands to monitor the discovery process:
AP0022.9090.e859#debug ip udp
To view the AP detail (controller ip, operational state, software version):
AP0022.9090.e859#show capwap client rcb
