A Big Move and Lots of Learning about Networking Fundamentals

I have been trying for a couple of months now to find good links and helpful information on what it takes to move a company, specifically the data center, as that is what I am responsible for.  As I move through this process though, I realize that I need to do a lot more than move some servers and routers. 

The past two days have been spent meeting with cabling companies trying to get a handle on what we need to get the the phones to ring and the computers connected to the internet and our servers.  It seems I need a cabling company to come and wire my building.  What they do is run all the wires from our server room to the rest of the building, but there is a bit more to it than that. 

There will be a demarcation point where the T1s will be dropped, I am most likely installing a T1 and a PRI, and the companies that drop those will only do that portion.  From there, I need to extend the demark to the MDF in our server room.  Because we are moving into a large warehouse, I also need to have them create an IDF and run fiber from the MDF to the IDF. 

While I am learning on the fly, I am finding it hard to find helpful articles on the web that explain this all.  Most sites focus on telephony or data networks but don’t explain how it all fits together.  If anyone out there knows of sites that explain all of this well I would love to see them.  I plan to share all I learn here, and hope that I expain it in a way that will make sense to me and others when I am done.

HP Laptop Trick

It has been too long since I posted, but I need to jot this little jewel down before all the learning I did today makes me forget this stupid, yet effective trick to bring a laptop back from what appeared to be a meldtdown.

My HP Pavilion laptop got stuck, so I powered down and tried to reboot, but I got all lights, but no display. Rebooted again, same thing, and I also noticed that my cd drive wound up but HD seemed to be out for the count in noise and in light indicator. Oh boy, figured my HD was toast and I would have to get a replacement. Went to HP support site where it said:

Test the AC adapter
Follow the steps below to determine whether the problem is related to the AC adapter or your notebook system board.

Remove the battery and disconnect all external devices from the computer.

Hold the Power button for several seconds, with all power sources removed. This drains residual power from the system, and may correct many problems.

Connect the AC adapter to a wall outlet and plug the other end into the computer.
Press the Power button to start the notebook PC.

Thanks HP! This worked like a champ and I am now happily blogging. Woohoo!
