Network Information

Jefferson Lab's Network

The network at Jefferson Lab is based on a high speed 10/100/1000 Mbps Ethernet model with dedicated bandwidth to every built in wall outlet, i.e. all switched. This model provides a robust and reliable solution to meet the demands of scientific applications that will require large amounts of bandwidth. Most buildings on site are wired with enhanced category 5 (CAT5e) cable, and the rest with high performance category 6 (CAT6) cable. From the office to the nearest closet switch, the link can be either 10 Mbps or 100 Mbps based on the network card available in the computer. Some groups on site have requested 1000 Mbps connections to the desktop and those can be filled on a case by case evaluation. From there the connection is moved, in most cases, over a high speed redundant gigabit (1Gbps or 1000 Mbps) backbone to various places on site including the central services such as scientific computing, email, web services, etc... Other mediums that a user can utilize for accessing the network can come from either dial-in services, modem connections from home, or local wireless ethernet connections, 802.11b. Various places around site, are equipped with multiple wireless access points to provide coverage in a certain area. These areas can be accessed any time as long as the user has obtained a correct SSID and WEP key from our wireless help pages.

When requesting a network connection for your machine, please make sure that the machine is assembled and located in its final location. The machine owner is responsible for moving and setting up the machine. This includes removing the machine from its box and making the keyboard, mouse, and monitor connections.

The Network Group will make the network connection from the wall plate to the machine only.
