The PC is in the top part of the cabinet, the UPS is the box on the left. Mounted in the blue front panel are some power switches, a clock that meters the runtime of the system and a modem (light device with the green LEDs in the upper part). The free storage room in the bottom of the cabinet holds the manual, the keyboard and a cordless phone. Notice, there is no monitor or other display in the system. Should it be necessary for maintenance purposes, the back of the cabinet must be removed (4 screws) and the monitor connected to the PC. But after the installation was finished there was no need up to now (March 1998).
