Network problems? Clean up your power first!

Now Spescom MeasureGraph offers a new way to see what is happening on your mains supply.
If you are experiencing intermittent network problems, do not automatically blame your system hardware. Many network faults are caused by irregularities in the mains power supply, like transients, sags, outages and frequency variations. And even if you have a UPS, these irregularities often pass through unfiltered to your system, where they can cause troublesome server failures, resets and system crashes.
So before you check out your system, it is worth taking a look at your mains power supply. And there is no more cost-effective way to do that than with Fluke's new VR101S voltage event recorder. The VR101S just plugs into a mains outlet and monitors the supply over time. While it is doing so, it can detect, log and time-stamp as many as 4000 voltage variations that fall outside preset limits.
Using the supplied EventView reporting software and optical interface cable, you can download a complete history of voltage events that occurred while the recorder was plugged into the mains supply. This gives you an overview of mains quality during that period, enabling you to pinpoint potentially troublesome events. Armed with that information, you can then decide on the right course of action to protect your network from future problems. The VR101S voltage event recorder is compact and easy to use at any point where you suspect power supply problems. All you have to do is plug it into the mains outlet. A flashing LED shows you if any out-of-limits events have occurred, so you can download them to your PC.
Your network is one of your organisation's most valuable resources. So do not leave power quality to chance.
