This is "The Server Closet."
The server closet is the upper part of the closet in my office that has been converted from a bedroom. On the right is a "telecommunications" rack in which I installed a patch panel (at the bottom) for all the telephone outlets in the house. Above it is the patch panel whose jacks are wired to the incoming voice phone line (the DSL Splitter on the back wall to the left splits the voice and DSL). Above it is the patch panel for all the ethernet outlets in the house. Above that is a Gigabit ethernet switch. On the top shelf my DSL router sits on the left and my DSL modem sits on the right. Out of sight on the back wall to the left is the DSL splitter that separates the telephone and DSL signals on the incoming phone line.

On the far left is the server. The server is an old 2008 Power Mac Prothat I bought on eBay. To its right are Two external hard disk RAID enclosures. Above them is a fan that keeps all the equipment cool. I used a foam panel to divide the closet, so that the heat from the computer, hard drives and other equipment is exhausted into the room. Without the fan the temperature in the closet exceded 95 degrees. After a router failed I mounted the fan. The router went from too hot to touch to comfortably warm.

The server runs the latest version of Apple's Mac OS X Server, that serves up this web site and e-mail. It also provides file services to other computers in the home and serves as the repository for all my mp3 and movie files. It serves up a database for the Hibiscuus Park Crime Watch and Neighborhood Association. Both of the external hard disk enclosures are four disk Raid 5 arrays that provide backup storage for the server and two other Macs in the house. The server runs without a keyboard, mouse or monitor and is controled from another computer by Apple Remote Desktop software. It runs Xtension, a program for controlling X10 devices (lights and alarms). Connected to it is a powerline interface that transmits signals from the computer through the electrical wiring to light switches and alarms. Also connected is a device (a W800) which receives wireless signals from security switches mounted on exterior doors and from motion detectors mounted inside and outside the house.

This whole project was invoked by my asking Fort Pierce Utilities to install a whole house surge protector. See The Saga Of The Surge Protector
