The night chest is a wooden box for children. It will be available in three sets : for girls, boys and a special limited Christmas edition.

During the night it can be used as a night light and as a toy storage box during the day. It can also be used to organise your affairs.

The target public is young children and adults. It will be realized in collaboration with cabinet making students.

This project is executed by Albane, Mathias, Chloé, Thomas & Yvan.

• Respect the EIA568A  and EIA568B standards
• Choose a straight or crossover cable

When wiring up a 10/100 Mbit/s

The only data cables used to share data are pins 2, 3 and 6

When wiring up a 1000 Mbit/s (16 bit/s) pin 8 is used.

When we plug a workstation to a hub or a switch a straight cable is used.

When we need to plug 2 workstations at the same time a crossover cable is used.

In a crossover cable the helpful pair is reversed, it  means that the emission pin pair 1-2 is connected on one side and the reception pin pair 3-6 is connected on the other side.
