			<content:encoded><![CDATA[<p>Whenever we buy anything for the company, I always ask if it can be connected to the network and monitored with SNMP.  For example, when a new HVAC system was installed in our building, I asked if it was going to be SNMP manageable.  The contractor looked at me like I was speaking Greek.  Out of curiosity, I decided to search on the idea and found this company called <a title="SNMP gateway" href="http://www.chipkin.com/snmp-data-conversion">Chipkin</a> that makes an SNMP gateway, as does the <a title="SNMP-OPC Gateway" href="http://www.thes4group.com/Products/SNMP-OPC-Gateway.aspx">s4group</a>.</p>
<p><strong>Why do I care about SNMP?</strong><br />
<a href="http://en.wikipedia.org/wiki/Trojan_Room_coffee_pot"><img class="alignright" style="border: 0pt none;" title="Trojan Room coffee pot" src="http://upload.wikimedia.org/wikipedia/commons/b/b8/Trojan_Room_coffee_pot_xcoffee.png" alt="" width="142" height="159" /></a>I care about SNMP because I want to manage everything from a central location.  We use <a title="network traffic analysis" href="http://www.plixer.com/blog/scrutinizer/network-traffic-monitoring-with-a-performance-dashboard/">MyView in Scrutinizer</a>. From a central location, we can monitor the network, the call center and, if we wanted to, the coffee pot.</p>
<p>BTW:  Fugoo is considering a marketing plan for their <a title="Fugoo Web-Enabled Coffee maker" href="http://www.tomsguide.com/us/pictures-story/54-3-CES-cases-cooling.html">network connected coffee maker</a>, however, it lacks support for SNMP and the <a title="RFC 2324" href="http://tools.ietf.org/html/rfc2324">Hyper Text Coffee Pot Control Protocol</a>.</p>
<p><span id="more-827"></span></p>
<p>Come to find out, the best idea for <a title="Trojan Room coffee pot" href="http://en.wikipedia.org/wiki/Trojan_Room_coffee_pot">coffee pot monitoring</a> is a simple web camera.</p>
<p><strong>SNMP Temperature Monitoring</strong><br />
We <a title="temperature monitoring solutions" href="http://www.ravica.com/products/is_humid.php">monitor temperature</a> in our data rooms, call center, conference rooms and offices, and we do it all with our temperature sensors. We even put an <a title="airflow sensor" href="http://www.ravica.com/products/is_airflow.php">airflow sensor</a> in our HVAC air intake to monitor when the blower came on.  I then polled for the SNMP information with <a title="SNMP performance trender" href="http://www.plixer.com/products/denika.php">Denika</a> and produced historical trends with the data.</p>
<p style="text-align: center;"><a href="http://www.ravica.com/"><img class="alignnone size-full wp-image-828" style="border: 0pt none;" title="bs2 hvac" src="http://www.ravica.com/blog/wp-content/uploads/2010/02/bs2-hvac.jpg" alt="bs2 hvac" width="300" height="225" /></a></p>
<p><strong>Summary</strong><br />
When we’re looking at hardware, equipment that supports SNMP generally makes it to our short list. All of our equipment supports <a title="SNMP monitoring" href="http://www.ravica.com/blog/tag/snmp/">SNMP</a>.</p>

Making sure that the investment your company has made into its networking hardware is well protected is paramount. However, normal temperature fluctuations are not the only potential danger to data room equipment. Power outages are another potentially hazardous event.</p>
<p>You&#8217;ve probably already placed <a title="battery back-up systems" href="http://en.wikipedia.org/wiki/Uninterruptible_power_supply">UPS devices</a> at the appropriate positions within the data center; which is the first step to protecting your investment. But if the power fails in the middle of the night and your UPS kicks in to keep your vital equipment running, how long will the battery backup keep your servers up and running, or better yet, your air conditioners and <a title="climate control systems" href="http://en.wikipedia.org/wiki/HVAC">HVAC systems</a>?</p>
<p>With the Ravica <a title="Voltage detectors can detect the presence or the absence of line voltage" href="http://www.ravica.com/products/is_acvs.php">AC Voltage Detector</a>, you can receive alerts when your systems switch to battery backup. Knowing immediately when your equipment is no longer running on line voltage can mean having the extra time to get a generator up and running or the core power issue resolved before batteries run out of juice and other systems begin to fail.</p>
<p>Temperature can even come back to bite us in this scenario. If your data room isn&#8217;t getting the proper cooling and ventilation, because the air conditioners or HVAC systems are no longer operational, you are now not only contending with power failures, but data center hot spots and equipment overheating as well.</p>
<p>The AC Voltage Detector is a simple sensor that works with any of the <a title="SensorProbe monitoring systems" href="http://www.ravica.com/products/index.php">Ravica SensorProbe models</a>. It detects voltage at 50 VAC to 250 VAC and runs on a open/closed contact switch system. You simply plug the cable into your UPS, like you would with any other piece of hardware. When the sensor detects the presence of line voltage, it reports a NORMAL status. When the power fails and the UPS switches itself on, the sensor automatically detects the change and reports an ALARM status.</p>
<p>Perhaps not every scenario calls for that extra line of defense, but when you consider the cost of data room equipment and the potential cost of that equipment&#8217;s failure, some extra measures to ensure its stability just make sense.</p>
