1.       Assume that your organization is planning to have an automated server room that functions without human assistance. Such a room is often called a light-out server room. Describe the fire control system(s) you would install in that room.

An automatic fire detection since there are no people present. And I think the air-aspirating detector system for the type of fire detection system would be suitable since the server room is a high-sensitive area with critical devices. This system works by filtering and moving the air through a chamber containing a laser beam. If the laser beam is diverted or refracted by smoke particles, the system is activated.  I would also consider what type of fire suppressor to implement based on the type of fire that could occur. Class C includes fires with energized electrical equipment or appliances; fires extinguished with nonconducting agents.  This is the type of fire that would occur in a server room, so attention should focus on a gaseous emission system that uses a clean chemical agent.  Clean agents don't leave any residue once dry and doesn’t interfere with the operation of electrical or electronic equipment.


2.       Assume that you have converted an area of general office space into a server room. Describe the factors you would consider for each of the following components:

a.       Walls and doors – Since it was a general office space, I would question what type of walls they are, standard or firewall. Most likely standard walls and this would need to be addressed. Also evaluate the doors, most likely they would need to be replaced by more secure ones.

b.       Access control - Know who has access to the room, consider upgrading the security by installing locks or some other secure means of granting access.

c.        Fire detection – Changing the type of fire detection to something more suitable for the equipment, like an air aspirating system.

d.        Fire suppression – Changing to a type more suitable for the type of fire and protecting the equipment, a gaseous emission system.

e.        Heating, ventilating, and air conditioning – Evaluate the reliability of each system to ensure temperature stays constant, humidity levels are maintained to eliminate the possibility of static electricity build up or condensation.

f.         Power quality and distribution – Consult with an electrician to ensure there is sufficient amperage for the equipment and for proper grounding.


3.       Assume you have been asked to review the power needs of a stand-alone computer system processes important but noncritical data. Although the system does not have to be online at all times, it stores valuable data that could be corrupted if the power system were suddenly interrupted. Which UPS features are most important to such a system?

Because the computer system does not need to be online constantly, I think a UPC featuring surge protection, power fluctuation leveling, data line protection, and a battery replacement indicator would be effective and efficient.


Which type of UPS do you recommend for it?

I would recommend a line-interactive UPS would be appropriate. It provides continuous power, even when utility power is gone, because it does not need a switch. The steady supply of power would keep the data safe from accidental loss.


4.       Define the required wattage for a UPS to be used with the following systems:

a.       Monitor: 2 amps; CPU: 3 amps; printer: 3 amps = 8*120=960VA

b.       Monitor: 3 amps; CPU: 4 amps; printer: 3 amps = 10*120=1200VA

c.       Monitor: 3 amps; CPU: 4 amps; printer: 4 amps = 11*120=1320VA


5.       Search the Web for a UPS that provides the wattage necessary to run the systems described in Exercise 4 for at least 15 minutes during a power outage.

a.       Eaton 5P 3000 Tower

b.       APC Smart-UPS 2200VA LCD 120V

c.       EnterprisePlus LCD E2000RTXL2U
