Exercises

1. Assume that your organization is planning to have a server room that functions without human beings---In other words, the functions are automated (such as a room is often called a lights-out server room). Describe the fire control system you would install in that room.

I would place a rate-of-rise system in the room to sense the ambient temperature inside of the room. If there were a fire to break out it would sense the change in the temperature and set off an alarm or other fire control device. I would also install a photoelectric sensor as this room is not controlled or accessed by humans the only cause could be smoke or flame triggering the alarm to go off. There would be a firewall in place to limit the spread of damage by fire if the fire originated outside of the server room. There would be four fire extinguishers in each corner of the server room rated for electrical fires. These would most likely be Halon or dry chemical extinguishers. The last fire suppression system I would install for use is the Gaseous Emission System. These are often found protecting electrical processing areas, as well as facilities that house computing systems.

2. Assume that you have been asked to review the power needs for a standalone computer system which processes important but noncritical data and does not have to be online at all times, and which stores valuable data that could be corrupted if the power to the system were suddenly interrupted.

Which UPS features are most important to such a system?

Standby or offline UPS systems- They are offline battery backup that detects the interruption of power to the power equipment. When the power quits flowing to the equipment, the UPS activates a transfer switch that then provides power from batteries, through a DC to AC converter.

Ferroresonant standby UPS- This is...
