All LAN cables entering or exiting a gland must have a 7.62 cm (3-in.) minimum drip loop. After the cables have been connected to the AP and the connections have been weatherproofed, gather each cable below the AP and form a drip loop.
Note
The drip loop prevents water from entering the AP by channeling water down and away from the connection points. Drip loops are required to ensure the proper operation of the AP.
