Data Center Cooling - The Do's and Don'ts of Network Equipment

Data Center Cooling

When working in an environment that operates with a high-density server, it can be an issue to make sure temperatures are safe for the equipment. This can become an even bigger issue when the equipment starts with a small amount of racks and then spreads into larger amounts. This is often seen within datacenters. The first thing that needs to be addressed is taking on the issue of cooling the rack individually. Information about this is in the do's and don'ts of network equipment.

Being able to cool a rack as it should starts with which rack you choose. You need to ensure that you have a rack that allows the necessary ventilation from front to rear. You will want to have a rack that either does not have doors or has perforated doors. You do not want a rack with doors that are solid glass or steel. You can also find racks that have a fan mounted in the top of it.

Once you have chosen the right rack for you, you will need to place the equipment properly inside it. Knowing the various do's and don'ts of network equipment can help with this. The best way to do this is by placing the largest equipment at the bottom and work your way up to the smallest equipment on the top. By doing this, you can be sure the air can circulate around the entire rack without having warm air trapped at the top. You should then make sure your equipment is set up properly with the pattern of airflow moving from front to back. This can be a problem with systems that are put together by users that use individual components, but is typically not an issue with systems that are manufactured commercially. There are some pieces of equipment that are designed to have the airflow move the opposite way, from back to front. With the equipment that has this type of airflow, it is important to ensure that you position them backwards when putting them in the rack. All of these details are why it is important that you know your network equipment.

If you find that your equipment is still running too hot after you have taken these steps from the list of do's and don'ts of network equipment, there are two potential solutions. First you will want to determine where the heated equipment is located. If it is the equipment near the top of the rack, you could purchase and install an exhaust fan that would be mounted on the top. This would help to circulate and pull out the warm air helping to cool the equipment.

The second thing to consider is whether or not there is space within the rack that is not being used. When there is space that is unused between servers it can sometimes allow for the hot air that is coming from the back of the rack to circulate around to the front of the rack making the equipment run hotter than it should. Within the list of do's and don'ts of network equipment, you will find that you should try to use blank rack plates in these cases. It will help to reduce the hot air from circulating this way and help to cool the equipment.

It is important to be sure the cabling of your used Cisco equipment does not block the airflow allowing the equipment to heat up more than it should. It is best to route the cables from the back of the equipment to the side of the rack and then vertically along the side.

Following the list of do's and don'ts of network equipment and ensuring that it is kept cool will help to make sure your equipment remains reliable and running properly for you.
