IntroductionIntroduction This project required us to obtain a network drawing and This project required us to obtain a network drawing and

determine the type of equipment used in the network. We were to determine the type of equipment used in the network. We were to determine, as well as possible, if the installation meets the determine, as well as possible, if the installation meets the National Electric Code Standards. National Electric Code Standards.

The network diagram used in this project was done by Garry The network diagram used in this project was done by Garry Meadows from the layout of his office. The network is a Meadows from the layout of his office. The network is a 10/100Mbps 802.3 Ethernet system used for sharing, accessing 10/100Mbps 802.3 Ethernet system used for sharing, accessing and storing data for use by office employees. All equipment is AC and storing data for use by office employees. All equipment is AC powered and connected to common 120VAC wall adapters; thus powered and connected to common 120VAC wall adapters; thus making it difficult to determine whether internal power regulations making it difficult to determine whether internal power regulations are met. All hardware, not desktop related, is rack mounted in a are met. All hardware, not desktop related, is rack mounted in a gray 23” steel, welded equipment rack. gray 23” steel, welded equipment rack.

The internal network connections were run through the false The internal network connections were run through the false ceiling to which Garry did not have easy access. Therefore, we will ceiling to which Garry did not have easy access. Therefore, we will use information we were able to obtain to complete this project to use information we were able to obtain to complete this project to the best of our abilities.the best of our abilities.
