Connecting to the Wired CUMC Network

To provide a secure environment, all computers used for CUMC purposes (whether institutionally or personally owned) must be registered with their IT Custodian, Certified IT Group, or other responsible person in their School, Department or business unit. Computers that are not registered may be blocked from accessing the network. Those that need access to the wired network (click here for Wireless information) must also complete a request for an IP (network) address as outlined below. Detailed policy information can be found on the Network Use page.

Registration simply means that current contact information and basic details about the system are provided. The information is used for emergency contact if it becomes infected with a virus or conducts suspicious activity (such as spamming or port scanning) on the network. Systems that move or change ownership must provide updated information as well.

Prior to Registering
In short any system connecting to the network must:

  1. Have received all critical updates and patches for their operating systems
  2. Have updated antivirus and antispyware programs running
  3. Be free of viruses, trojans, and other malicious programs

The network is regularly scanned for malicious activity and infected hosts; systems that pose a threat may be blocked or restricted from connecting. Additional requirements such as setting a password, auto-lock, and running regular backups can be found in the Registration and Protection of Endpoints policy.

Required System Information
When submitting a registration form you will need to include a few technical details:

  • The device and operating system type - see What OS does my computer use? for help
  • The MAC (Media Access Control) Address - a unique set of 12 characters that is hard coded on every network card. Instructions below can help you find this address; be sure to record and enter it carefully or the computer will not be able to connect.
  • The jack or data port label - the port where a network cable can be "plugged in" should be labeled, see below for help. Some ports may not be active or may be configured for specialized equipment; having the label information allows network staff to verify that it is ready to be used.

Finding a MAC (Network Card) Address
Be very careful to record and enter the address correctly. Each MAC address - also referred to as a Physical or Hardware Address - is unique world-wide, and is used to recognize the system on the network. For help select the appropriate link:

Windows 7 (or Vista)
Windows 8
Macintosh OS 10.9 through 10.6

For other types of systems please contact 5-Help or your department's own technical staff to get assistance with finding its MAC address. If you'd like to register a system that was recently purchased but has not yet arrived, the vendor may be able to supply the MAC address for you in advance.

Jack Port Finding a Jack Port Label
"Jack" or Data Ports are labeled within their wall plate, immediately adjacent to the port. This is where the system's network cable is plugged in. The wall plate may also include ports for a phone.

  • Jack ports for a computer will typically be red or orange, as shown in the picture to the right. Blue ports are NOT for data connections; these are phone connections only.
  • Valid jack port labels will start with a campus building abbreviation and end in "D1", "D2", etc., with the last two digits indicating the different data ports on the individual wall plate.
  • Please make sure you are submitting the correct, full string of characters for the individual data port that will be used; submitting incorrect information could delay the request. The characters on the labels are not case-sensitive.

Registration Forms
Select a link and login with your Columbia UNI and password to submit your request:

  • New IP Request - to register a computer or other system for the wired CUMC campus network.
  • Update IP Request - for already registered systems that are changing location, ownership/primary user, or getting a replacement network (NIC) card. Please also submit this if a computer will no longer be used on the network so we can accurately track available addresses and connectivity on campus.
  • Network Port Activation - to have an existing data port made active.
Other related requests include Computing Relocation (configuring computing equipment that is being moved within the CUMC campus) and Network Port Installation.

Once the form has been submitted you will see a request number, please record this for your records. Within a few business days of submitting the form you should receive email confirmation that your IP request was processed and your newly registered system will be able to connect shortly afterwards.

Be sure to read the email confirmation closely, as it will let you know whether the systems should remain dynamic, using DHCP to connect to the network (this is the default setting on most computers), or if it will require manual configuration of a network address. Most systems connecting to the CUMC network should be set for dynamic or DHCP configuration. The network automatically refreshes its list of approved MAC addresses throughout the day, so please realize it may take a few hours after receiving your confirmation email before your system can connect.

More information on the wired network can be found in faculty and staff and student FAQs.
