One of the basic parts of your network infrastructure is, of course, your power supply. It's as basic as you can get, but you can't afford not to understand how your systems are powered and what kinds of problems to look out for. American Power Conversion (APC) has provided a very detailed white paper on the seven kinds of power problems as defined by the IEEE:
3. Sag / Undervoltage
4. Swell / Overvoltage
5. Waveform distortion
6. Voltage fluctuations
7. Frequency variations
According to the executive summary, here is what you'll find:"Many of the mysteries of equipment failure, downtime, software and data corruption are often the result of a problematic supply of power. There is also a common problem with describing power problems in a standard way. This white paper will describe the most common types of power disturbances, what can cause them, what they can do to your critical equipment, and how to safeguard your equipment, using the IEEE standards for describing power quality problems."If you need some remedial work in power supplies, check out the download.
