Case Study: Water Enters an AP Because the AP Is Not Waterproofed
Symptom
Water or insects enter APs, corroding or damaging internal components.
Relevant Alarms and Logs
None
Cause Analysis
- No drip loop is made on network cables during AP installation. Water flows into APs along network cables, corroding or damaging the APs.
- During the installation of an outdoor AP, no rubber liner is installed on the network port of the AP, and the network port is not sealed. As a result, water enters the AP and the AP is damaged by insects.
Procedure
- Make drip loops by referring to the specifications in the hardware installation guide. For details, see Guide to Making Drip Loops.
- Take waterproof measures on the PG connector. For details, see Connecting Cables in WLAN Hardware Installation and Maintenance Guide.
Suggestion and Summary
Waterproof measures must be taken to prevent water from flowing into APs along network cables after condensation. For example, it is recommended that drip loops be made on the cables connected to the APs.
If a network port of an outdoor AP is not installed with a rubber liner, the waterproof performance of the network port will be poor and the AP may be corroded by water. To prevent this problem, install the AP by strictly following the Hardware Installation and Maintenance Guide.
