Example for Switching a Fit AP to the Fat Mode Using Uboot
Applicable Scope
It is recommended that the AP mode be switched using a method described in the preceding part. If the switching fails, consider switching the AP mode in Uboot mode.
Applicable version: versions earlier than V200R019C10
Applicable model: APs that support the Fit and Fat modes and have a console port
Networking Scenario
If the mode switching using the preceding methods fails, you can use the Uboot mode to switch the AP mode.
Connect the AP to a PC through an Ethernet cable in a proper mode, as shown in Figure 4-14.
If the AP supports DC power supply and works with a power adapter, connect the AP to a PC directly through an Ethernet cable. If the AP does not support DC power supply or no adapter is available, supply PoE power to the AP. In this case, connect the AP to the PC through a PoE device.
When the PC serves as a TFTP server, prepare the Fat AP software package for the AP to obtain through TFTP.
Quick Configuration
This section helps you quickly configure an AP, without the need to read the entire document. If you are not familiar with the product or operation, read the detailed guidance in the following sections.
