Gigabit Uplink Unmanaged Switch
■
When cabling indoors, keep a certain distance away from the devices that may cause
high-frequency interferences, such as down-conductor cable, powerline, power
transformer and electromotor.

The two diagrams below demonstrate parallel net length and parallel-overlapping net
height.
Note: The above minimum net length/height is required when metal raceway is not
used. If any requirements cannot be met, you can add a steel tube or metal raceway
for shielding.

Requirements for Cabling Indoors
The main cable should be paved in the metal raceway of the access shaft. When
cabling, keep the loop area formed by the cable itself as small as possible.
Requirements for the distance between Ethernet cable and other pipelines are
shown in the table.
Requirements for the distance between Ethernet cable and high-power electric
devices are in following tables.
