Floor plan

Create a detailed project plan using the aforesaid information about devices, cables lengths, topology, junc-

tion boxes and Y-connectors.

Are the devices close to each other?

YES: plan the network with a passive junction box

NO: plan the network with Y-connectors

Rules:

▪ Connect all the accessories on the trunk line

▪ Connect the accessories directly to the device

– Use stub lines to connect the devices

– Avoid long stub line lengths

6.1.1

In a network with one passive junction box, all the cables will be viewed as stub lines since there is no trunk

line. Keep the stub lines as short as possible.
