Before You Start
Before starting maintenance of AC and Fit AP products, you are advised to:
- Collect the network plan and data of the entire network, make a topology diagram and a data table (including ports, IP addresses, service and management VLANs, and SSIDs), and attach them in a position easy for you to check the topology and data.

Data backup helps you quickly locate and recover faults. After a network is set up and operates normally, you should back up important data as soon as possible.
Important data includes:
