|  | 8.8 | Design Practice No. 1: Wiring Plan for Ethernet Star Topology LAN
| 8.8.1 | Overview

Develop a wiring plan for an Ethernet extended star topology LAN, that uses both fiber-optic and CAT 5 UTP cabling. The description of the network area is as follows:

- The campus has three buildings.
- Each building is two stories tall.
- The dimensions of the main building are 40 m. x 37 m.
- The dimensions of both the east building and the west building are 40 m. x 23 m.
- Each building has a different earth ground.
- Each building has only a single earth ground.
- All floors are covered with ceramic tile, unless otherwise specified.

On the floor plans, the following locations have been indicated:

- MR = men's restrooms
- WR = women's restrooms
- POP, in the main building
- power line entry into each building
- water line entry into each building

Provide a plan to network the computing devices, in all three buildings, in an Ethernet extended star topology. As you develop your networking plan, assume that two computing devices are located in each numbered room. Your plan should show each of the following:

1. location of the MDF
2. location and number of IDFs
3. identity of IDFs used as HCCs
4. identity of IDFs used as ICCs
5. location of all backbone cabling runs between MDF and IDFs
6. location of any backbone cabling runs between IDFs
7. location of all horizontal cabling runs from IDFs to work areas

Don't forget to indicate on your floor plan the location of any backbone cabling runs between floors, and between buildings. In addition, your plan should indicate what type of networking media you plan to use for the horizontal cabling, and for the backbone cabling.
