The School provides a uniform standard of ethernet support in all offices and labs in all three of its buildings. All network faceplates (called "Telecommunication Service Outlets" or "TSO"s) contain orange data jacks utilizing "category 5" wire to network closets. White jacks in the same TSOs are for telephone service only.
Active network data jacks (not all jacks are active) are connected to dual speed 10BaseT/100BaseT ethernet switching hubs. Gigabit ethernet is not supported in the School and there are no plans to do so. Individual research groups can get gigabit ethernet connections among their computers if they provide the funds to purchase the necessary switching equipment. Contact the School's network manager to arrange this.
The ethernet switches in the communications closets have high speed backplanes to support multiple simultaneous full bandwidth connections. These switches are connected to each other in simple hierarchical arrangements with either "trunked" 100BaseT links (effectively creating a 200 megabit per second link) or gigabit links. The master switch for each building connects to the campus backbone network via a fiber-optic cable link running at 100 megabits per second.
