Add a Computer to the Network

• An Ethernet wall jack
  Not all Ethernet jacks are active. If you wish, please let us know your jack number in the form below and we will verify that the jack is active.
• An Ethernet cable
  10 feet or less in length. You can obtain a cable from us by stopping by 333 or 332 Morrill Hall. There are currently three different wiring types in use, so please don't use your own cables.
• Knowledge of the Life Sciences and UIUC computing policies
• A locally-assigned IP address for your system

Please read the info below and submit the following form to request a life.illinois.edu IP address for your system. We will then assign an IP address and respond shortly.

Policies

There are restrictions on the use of the network. Policies regarding the use of the illinois.edu network can be found at http://www.cio.illinois.edu/policies.html.

UIUC Life Sciences also has the following policies to ensure the overall health of the network:

• Microsoft Windows systems must have up-to-date anti-virus software installed.
• Security patches must be kept up to date.
• Each system must connect directly to a wall jack. Systems may not be used as, or connected to, a router, switch or hub.
• The maximum cable length from wall jack to system is 10 feet. Cables should be as short as is practical for best performance.
• Cables must have a clear path from wall jack to system. For instance, they may not pass through doorways, across ceilings or floors, or come near devices that generate electrical interference.
• IP address assignments will be retired when the system has not been attached to the network for six months.

IP Address

For a computer to communicate on the life.illinois.edu network, a local IP (Internet Protocol) address must be assigned to your system. All modern devices come pre-configured to obtain an address from a server using the Dynamic Host Configuration Protocol (DHCP). Your system will automatically ask for an address each time it is attached to the life.illinois.edu network and our DHCP server will provide the same address on each occasion. This is called "static addressing via DHCP".

Every Ethernet device is assigned a unique adderess when it is created, and we use this address to associate the life.illinois.edu IP address with your computer.

Security & Backup

Our web page, http://www.life.illinois.edu/help/faq/security.php, gives an overview of steps to secure your computer. Please evaluate these steps as soon as possible.

If you wish, we can backup your computer when it is attached to the life.illinois.edu network. For more information, see http://www.life.illinois.edu/help/backups/.
