Wire closet at work. Avaya digital PBX system on right; Ethernet hubs at left; DSL/WiFi router at center; RAID NAS between the router and the PBX.. The PA system at upper left was blown out during a power surge last month. Luckily everything else was on an APC battery backup/surge protector.
The occasion for the photograph is that I replaced a hairball of different length patch cables with uniform two foot long cables. Makes everything a lot tidier.
This image shows the black & white coaxial cables landed on their modules. The colors are separated out to match the wallplates around the house. The white coax on the left becomes the left hand coax jack while the black coax is the right hand jack.
The coaxial cable is used to carry Cable TV, Satellite TV, Video Cameras, Nanny Cams and a variety of other signals around the home.
The 4 white coax on their own are wires that have been run to the roof for a future satellite or antenna connection.
If you notice at the top of the picture, the 4 roof coaxial wires are landed on top of a plate that runs left to right across the structured wiring can. This is called a Grid Lifting Wire Manager and allows us to run wire underneath carious modules instead of having it stack up on the side of the can and get in the way.
Here you can see the wire has been broken out/separated inside the wall and feed into the can. Notice how the CAT5e wire is routed down one side of the can - this keeps it out of the way of the Coaxial Cabling.
The 2 top wiring blocks show theCAT5e separated out by color/function. We use Blue for Data/LAN/Home Network and the White for Phone. Using these wiring punchdown blocks allows use flexibility - for example of we needed an extra data line, we can patch into an unused phone connection.
The block on the lower left distributes 4 phone lines to upwards to 12 different connections. Each patch cable run from this bock to a connection on a phone or data punchdown block gives a live phone jack somewhere in the house.
The module on the lower right is a combination Phone Line Surge Protector and DSL filter. Phone service comes in from outside the house and we run it into this module. From there we have connections for the main phone lines in the house, a DSL modem, a security panel hookup and a test/service connection.

Weekend work. Making sure that everything comes up properly after a major change. Exciting times!
Cory Hall 3rd floor network closet during the 1997 network upgrade project.
This is a completed CAT5e punchdown block. All wiring has been looped under the block in order to keep it out of the way of patch cables that will be connected to the block.
This picture shows multiple punchdown blocks, a phone line distribution module and a DSL filter
A contractor works in the Cory Hall 3rd floor network closet during the 1997 network upgrade project.
Switches were upgraded from old Cisco 2900 XL & 4000 series to Cisco 3750 Stack. New patch cables installed with clean routing.
I have a few pictures to post from the Henry Ford Museum trip I took with Joey, Patrick and John; but for some reason the machinery and cars on display didn't inspire me photographically all that much.
But somehow this little behind-the-curtains detail spoke to me. Someone had left the door to the wiring closet open while stringing new cables. This was the rack of audio gear that provides background music piped throughout the building.
the rack in the wiring closet. Mainly, I took this picture to show you the coke cans on the antena of the wireless access point. This little DIY fix added 10% to the signal of the AP.
Our little computers for our wireless labs have arrived! They just need their carts and to be imaged and we are ready to go!
Behind the AV wall in the Media Center. This houses our vcrs and dvds that are controlled by the telephones in our classroom.
