8.8 Design Practice No. 1: Wiring Plan for Ethernet Star Topology LAN 8.8.1 Overview Instructor Note The purpose of this target indicator and subsequent pages is to give the students more practice on some of the basic choices of network design: backbone cabling and the location of MDFs and IDFs. 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 120 m. x 112 m. The dimensions of both the east building and the west building are 120 m. x 68 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:location of the MDF location and number of IDFs identity of IDFs used as HCCs identity of IDFs used as ICCs location of all backbone cabling runs between MDF and IDFs location of any backbone cabling runs between IDFs 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.

They are marked on the plan of the second floor of the main building as G, H, I, J, and K. Location G uses incandescent lighting. The door opens into the room and is not secured with a lock. The light switch is to the left of the door upon entering. Interior water lines run through the dropped ceiling space along the right cinder block wall. Fire-retardant paint covers all walls. There are four electrical outlets in the room. Location H uses fluorescent lighting. The door opens out of the room and can be secured with a lock. The light switch is to the right of the door upon entering the room. The room does not have a dropped ceiling. The walls are of cinder block construction and are painted with a fire-retardant paint. There are five electrical outlets in the room. Location I uses incandescent lighting. The door opens out of the room and can be secured with a lock. The light switch is to the right of the door upon entering the room. The room does not have a dropped ceiling. The walls are of cinder block construction and are painted with a fire-retardant paint. There are six electrical outlets in the room. Location J uses fluorescent lighting. The door opens into the room and cannot be locked. The light switch for this room is outside the room on the opposite wall of the hallway. There is a dropped ceiling in the room. The walls are of cinder block construction and are covered with a fire-retardant paint. There are two electrical outlets in the room. Location K can only be reached by passing through Room 212. The room has incandescent lighting and is used to store toxic chemicals for experimental purposes. The door opens out of the room and can be secured with a lock. The light switch is to the left of the door upon entering the room. The room does not have a dropped ceiling. The walls are of cinder block construction and are covered with a fire-retardant paint. There is one electrical outlet in the room.

Its dimensions are 120 m. x 68 m. A preliminary survey of the building has been made. Three potential wiring closet locations have been identified for the first floor. They are marked on the floor plan as L, M, and N.Location L is near the front entry of the east building. The room uses incandescent lighting. The door opens out of the room and can be secured with a lock. The light switch is to the left of the door upon entering the room. There is no dropped ceiling in the room. The walls are of cinder block construction and are covered with a fire-retardant paint. There are three electrical outlets in the room. Location M is where the main water line enters the east building. The room uses fluorescent lighting. The door opens out of the room and cannot be locked. The light switch for this room is outside the room to the left of the door. There is no dropped ceiling in the room. The walls are of cinder block construction and are covered with a fire-retardant paint. There are two electrical outlets in the room. Location N is where the main power line enters the east building. The room uses incandescent lighting. The door opens out of the room and can be secured with a lock. The light switch is to the right of the door upon entering the room. There is no dropped ceiling in the room. The walls are of cinder block construction and are covered with a fire-retardant paint. There are four electrical outlets in the room.

Its dimensions are 120 m. x 68 m. A preliminary survey of the building has identified three potential locations for wiring closets on the first floor. They are marked on the floor plan as R, S, and T.Location R is where the main power line enters the building. The room uses incandescent lighting. The door opens out of the room and can be secured with a lock. The light switch is to the left of the door upon entering the room. The room does not have a dropped ceiling. The walls are of cinder block construction and are covered with a fire-retardant paint. There are four electrical outlets in the room. Location S is where the main water line enters the building. Water lines pass through the dropped ceiling space and lead to adjacent men's and women's restrooms. Like location R, this room uses incandescent lighting. The door opens out of the room and can be secured with a lock. The light switch for the room is just outside door and to the right. The walls are of cinder block construction and are covered with a fire-retardant paint. There are three electrical outlets in the room.

They are identified on the floor plan as U, V, and W.Location U uses fluorescent lighting. The door opens out of the room and can be secured with a lock. The light switch is to the left of the door upon entering the room. The room has a dropped ceiling. Walls are covered with an asbestos material. There are four electrical outlets in the room. Location V has interior water lines that pass through its dropped ceiling space and lead into adjacent men's and women's restrooms. The room uses incandescent lighting. The door opens out of the room and can be secured with a lock. The light switch is to the right of the door upon entering the room. The walls are covered with an asbestos material. There are four electrical outlets in the room. Location W is near the front of the building. The room uses incandescent lighting. The door opens out of the room and can be secured with a lock. The light switch is to the right of the door upon entering the room. The walls are covered in a fire-retardant paint. There are two electrical outlets in the room. Web Links Cabling Glossary
