Network Operations Center (NOC) Guidelines

IP Phones

All IP Phones must be attached directly to a data jack. They should not be connected to hubs or switches. This is necessary to ensure proper voice quality and 911 services.


All user cables must remain within a room. Cables can not be extended through doorways, walls, ceilings, etc. This is important for several reasons. Cables leaving a room are most often a fire or safety violation. They also contribute to Ethernet loops, which can cause network outages.

All data jack to network device cables must be 14 feet or shorter. This is a network design requirement that, if ignored, can lead to intermittent or poor performance on some data jacks.

Network Devices

Wireless Access Points

Wireless Access Points should not be connected to the campus network. They interfere with campus wide wireless coverage provided by NCT, and they pose a security threat to the campus network.


Computer labs and server farms may be run with user supplied switches. NCT recommends a higher speed server connection for these instances.

NCT does not recommend hubs and switches for use in offices, however it understands departments may wish to do this in some situations. When hubs and switches are used:

NAT devices should not be used unless all machines behind the NAT device have been registered for use on the campus network via the ordering process.

DHCP Servers

Departments wishing to run a DHCP server must first contact the NOC. By default, all DHCP server traffic is blocked at the data jack level. This is to prevent a home network device that is improperly plugged into the data jack from bringing down the network. Note that DHCP client traffic from user machines is not blocked.
