How can I connect to the network?
For any computer set up you should first communicate with your department's business office to verify that you are following all internal procedures. The Connecting to the Wired CUMC Network web site outlines general procedures on registering and connecting a computer or other device, most of which must be done by your Certified IT Group. All systems must be properly registered with CUMC/NYPH's CORE Resources prior to using the network.
How do we get IP (network) Addresses?
When staff in your Certified IT Group inventory and register a system they will use a form online to request an IP address. This requires the Hardware Address of the system that will be connecting (also known as a Physical, Ethernet or MAC address).
This Hardware Address is unique to the computer's network interface card, or NIC, world-wide, and is how the computer will be
recognized on the network.
What hardware does a computer need to connect to the wired network?
Devices plugging in to the wired network need an ethernet port and network cable (also known as Cat-5 or Category-5 cable). If your computer doesn't have a built-in ethernet port, you may be able to purchase an ethernet adapter to connect to the computer. A network cable is thicker than a phone cord and has connectors on the end that look similar to phone connectors but are slightly
How do we find the computer's hardware address?
Certified IT staff will be able to find this for you, or you can see instructions on our Find a Computer's Hardware Address page to look it up on the computer. The hardware address may also be included in any documentation, labels or ordering information from the vendor or manufacturing company.
Keep in mind that this a device's hardware address is unique world-wide and how it will be recognized on the network; be very careful to record it accurately.
Can I choose any IP Address?
No, you may not choose your own IP address. Picking an IP Address has the potential to cause more harm than good, see Network Addresses and Naming requirements for full information. CORE Resources considers this "stealing of network resources" and will render your
network card inoperable on the network. A Security Incident Report will be created and your computer will be found. A decision is
then made as to whether your connection can be reactivated or if further action is to be taken against you.
For further assistance:
- Columbia University staff and faculty should contact the Certified IT Group for their department. If you do not have one or if you are unsure if your department has an IT group, contact your business
- If you still have questions or if you are unable to get your computer connected to the network, you can contact the
Service Desk at extension 5-Help.
How long does it take to process my registration and connect?
It can take a few business days to process correctly submitted wired network registration. The IT custodian who submits the registration form will be notified and the computer will automatically receive its
"IP" address when plugged into the wired campus network. Most computers are able to connect soon after being approved; be sure to carefully review any information you receive regarding registration and approval to avoid possible issues or delay.
Should I request a manual IP address?
We recommend that you do not request a manual IP address (one that has to be manually configured within the computer's network
settings). A dynamic (not manual) address is generally much easier to use, and allows for roaming if using a laptop.
Can we use our laptops anywhere?
Registered laptops may be used anywhere on campus and remote sites. If you only have wireless capabilities, your coverage area
is much smaller. To find out the current locations of the CUMC Wireless Network, please see the list of
Where do we plug in?
Network cable data connection outlets should have an identifiable orange label on them. They are usually red or blue in color and
look similar to a telephone connection.
Connecting an Ethernet network card to a telephone outlet can cause severe and irreparable damage to the card and/or your
computer, please make sure you are putting the ethernet cable into the correct data port. A data port is slightly
larger than a telephone port, and most ethernet cables will not easily fit into a telephone outlet.
Who assigns the IP addresses?
The group that manages the network for the entire CUMC and NYP campus, CORE Resources,
assigns the IP addresses. Please remember that if you have any issues or questions regarding the campus network you must first
contact the CUMC IT Service Desk at extension 5-Help, option 5.
All requests for IP addresses must be submitted online in ServiceNow by staff in an approved CUMC Certified IT Group.
How can I transfer files over the network?
The above meet requirements for transferring all levels of data, including those classified as sensitive and confidential. Common file sharing services such as Google Drive and Dropbox are generally not approved depending on the type of data, please see Columbia's External Hosting and Data Classification policies for more details.
- If you have a CUMC email account (ending in @cumc.columbia.edu), please see this FAQ.
- If you need to share large files with others in your department there is typically a shared network drive that can be used.
- DatAnywhere can be used to transfer large files with others, without the need for VPN or a CUMC related account.
- CUMC's OneDrive for Business allows sharing files with others who have a CUMC email account.
