How to Protect Your Computer Server Room From Threats

How much money do you have invested in your server room? What would it cost you if you were to lose all its functions due to environmental conditions your gear couldn't handle? The answer to both of these questions is likely, "a lot."

Being unaware of the status of your server room will cost you a fortune in the long run. Too many people try to save money now by leaving their gear unmonitored - only to end up with massive costs the instant they suffer a network outage.

The TempDefender remote telemetry unit can monitor your server room by communicating with smoke detectors, temperature sensors, interior motion sensors, humidty sensors, door sensors, and floor water sensor.
Using a remote telemetry unit (RTU), you can protect your computer and server room from environmental conditions.

The Key to Protecting Your Equipment and Infrastructure

The good news is the answer to monitoring your gear is simple. By using a remote terminal unit (RTU), you can monitor all of the factors that could damage your gear. Here are the six key threats you need to protect your computer server room gear from.


Computer equipment generates a lot of heat and, if the temperature of your server room gets too high, your gear will likely shut down due to overheating, bringing your entire network to a crippling halt. By using live analog sensors, you can monitor the precise temperature at all times - so you're always aware if there's a problem in your air-conditioned data center.


While humidity threats are much more unexpected than temperature threats, that doesn't mean they're any better. If the humidity levels are too high, you run the risk of water build-up on the components of your gear - which could lead to rust and gear failure. Humidity levels that are too low are also dangerous. Low humidity leaves your gear susceptible to static electricity, which could seriously damage your gear.


If a power outage happens to your server room, you need to know as soon as possible, so you can either restore power or get your backup generators going. You can't afford to lose power to your key networking equipment and find out later from your customers calling in and complaining. Don't leave yourself in the dark - monitor the power sources that are keeping your revenue-generating gear online.

Water Damage

If you rarely go into your server room then a slow water leak could steadily build up and cause severe damage. A few drops of water in the wrong place could short circuit several pieces of mission-critical gear, leading to network downtime and lost revenue. Using water detectors can give you an early warning when water is threatening your network.

Air Flow Disruptions

One of the simplest, least expensive, and more effective ways to control the temperature of your server room is to use airflow management. By properly managing air circulation in your computer server room, you can regulate the temperature in a cost-effective way.

However, if there is a disruption to this flow, or one of your cooling units goes down, it won't be long before your servers execute thermal shutdowns. By using airflow sensors, you can be notified the instant the air in your server room isn't being properly circulated.


Your server gear is valuable, so it's absolutely key that you put in place physical security as well. This is especially important if you have gear located at a remote site that's away from your central office. With access controls, you'll be able to know the instant you have an unwanted visitor, avoiding damaging vandalism or theft.

By monitoring these six key threats, you'll be protected from preventable network emergencies that could have caused an outage - halting service to your customers and costing you tons of revenue.

Where to Find the Technology to Remotely Monitor These Conditions?

Now you know how these threats can cost you a fortune in the long-run, and you're ready to do something about it. The good news is protecting your network doesn't have to be a hassle, and it doesn't have to break your budget. Using a combination of Remote Telemetry Units (RTUs), Master stations and sensors can give you the visibility you need to protect your server room and your mission-critical gear.

The Ultimate Protection for Your Server Room and Gear

To monitor various spots in the server room from a single device, DPS Telecom makes the TempDefender. The TempDefender is a small, rack-mountable remote telemetry unit (RTU) that can handle up to 16 analog sensors reporting on all of the environmental factors in your server room.

Sensors for the TempDefender may be daisy-chained together, so you don't have to run a mess of cabling back to the TempDefender. You can also string sensors up to 600 feet away from the RTU, allowing you to run sensors to the most extreme spots in your server room from a centrally located device without worrying about connectivity issues.

Be careful if you measure your server room cooling system this way. Be sure to run sensors to spots likely to be hot. These include above equipment, hot aisles, and near your hottest racks.

You should also place sensors where air flow is most necessary. This can include hot air aisles on both sides of your cold aisles. This will ensure even cold air distribution.

You want to ensure that air, both cold and hot, is being effectively moved through the system. Losses and inefficiencies result in hotter server rooms and more energy expended in the cooling process - it's not as bad as a complete meltdown, but still not optimal.

The Best RTU for Environmental Monitoring

If you're looking for a rack-to-rack solution, you should consider something like DPS Telecom's NetGuardian 216 G3 remote. The unit has four analog inputs, with which to measure the environment within the rack (or string sensors across a few racks) and 16 discrete alarm inputs so you can directly monitor your servers and other equipment.

The NetGuardian 216 provides a total solution with which you can monitor environmental sensors and the dry contacts coming directly from your servers, so whether your problem is environmental or otherwise, you'll know about it.

Picture how much easier your job would be with this kind of protection. Imagine - you'll never be the last to know about a threat to your gear. Having the ability to prevent many network outages doesn't have to be a dream - you can make it a reality.

The first step to protecting yourself against damage is to make sure you have the right info. Too many monitoring systems don't see the big picture and leave out vital features that can mean the difference between an outage and network up-time.
