UW-Madison College of Engineering CAE Hardware/Network Support Staff

 

COE Network FAQ :

1. I am a new faculty/staff member here, what do I need to do to connect my computer/printer to the COE network?

Contact your departmental support person, and they will innitiate the required steps to connect you to the network. Your support staff will want to know: your name, the physical address (MAC) of the computer/printer you wish to connect, your building room number, and your advisor.

2. I am an existing faculty/staff member here, and I need to connect my computer/printer to the network from a new location.

If there is not already an active datajack in the new location, email hardware@cae.wisc.edu and be sure to include: your name, the location you moved from, the location you are moving to, the designaiton of the datajack you wish to be activated (eg: 2532-D024), and who your advisor is.

3. What is the coverage area for the COE wireless network, and how can I connect to it?

The following site will answer all your COE wireless network questions: http://www.engr.wisc.edu/computing/wireless.html

4. What type of ethernet cable do I need to connect to a datajack in my area?

The ethernet cables that CAE Hardware provides now are all CAT5 twisted pair, however the wiremap and jack head required does vary with location and intended use. Some of the in-wall wiring in the COE is CAT3 twisted pair, while the newer in-wall wiring is CAT5 twisted pair. Standards and technology for ethernet wiring have changed greatly over the last few decades, and as these changes occur the COE adds new data lines to support them where needed. This leaves us with the unenviable task of supporting several different wiring schemes throughout the COE.

The two wiring standards used in the COE are USOC and T-568B. Older datajacks in the COE are wired USOC and require an RJ-11 connector to work properly. The newer datajacks are wired T-568B and require an RJ-45 connector to work properly. (see diagram below)

The following pictures show some of the different types of wall datajacks found throughout the COE. Generally, (but not always - consult the above table to be sure) the beige datajack boxes are USOC CAT3 connections. On the other hand, an orange datajack connector always designates a T-568B CAT5 connection.
