Inspect your desktop hub for dust accumulation at least once every three months. Before inspecting your
hub, turn off the power and unplug the hub's power cord from the electrical outlet; then remove any dust
from vents and perforations in the bezel. If you notice external dust accumulation, then examine and remove
dust from the inside of the hub including heat sink inlet fins, power supply vents, and fans. Always turn off
and unplug the hub before opening the cover. If possible, avoid operating your hub within two feet of high-
traffic areas. If you must operate your hub in or near a high-traffic area, inspect and, if necessary, clean your
hub more frequently.
