DPS clients sometimes struggle with rack space in small cabinets where the revenue-generating equipment already takes up a lot of space. If you have a small site, it might be that you don't have any rack space left at all.
In these situations, you need to know how to maximize the space you already have. After all, not having monitoring equipment is not an option.
This is the most common option to mount monitoring equipment. Racks can be either 19 inches or 23 inches in width. Rack-mounted equipment needs rack ears to attach to the rack.
DIN Rail Mount
This is also another common way to mount your RTU. A DIN rail can be mounted to a wall or attached to a standard rack, either way, you will need extra hardware. This extra hardware will be special brackets that will mount devices to the DIN rail (imagine books on a shelf).
DIN mounting is more space-efficient than a simple rack mounting. DIN mounting will require more space to start with, but you can place more than one device across it.
You can also wall mount your devices. In this option, you will use special brackets as well, but they allow you to mount your gear to virtually any flat surface that accepts screws. If you don't have any rack space left, wall mounting will allow you to place your gear inside of a cabinet door. Also, you can mount the device to any wall.
Another advantage of this method is that wall-mounted electronic equipment makes it easier to access wires in both front and back ports. After wall-mounted, front and back ports become top and bottom ports - this is why they are easy to reach.
In some cases, large rooms that were once necessary for a big physical piece of gear, such as a telephone switch, can be replaced with just a small software box. This results in having plenty of rack space available for remote monitoring equipment and other gear.
Auxiliary equipment, like PDUs, can be available in 0RU models that mount to the side of the rack or otherwise stay out of the way and don't use rack space.
Other than struggling with rack space in small cabinets, many of our clients have ventilation as an issue. To solve this issue, we recommend that you try to leave space open for air to flow. So, don't completely fill up your rack space.
Cable management is also important for the organization and airflow. Different wire termination is more secure (wire wrap) than others (flip-lock terminals). Protecting wires and connectors from someone accidentally brushing against them and pulling out wires is important. Use physical protectors when possible.
Good remote monitoring using NC (Normally Closed) configuration will "self-monitor" and know when wires have been disconnected.
1U is the height unit of measure of rack-mountable equipment. One U equals 1.75 inches, which is also the standard for measuring the height of rack-mounted gear. The number that comes before U is simply the count of rack units that a specific device will require to be mounted to the rack.
A typical full rack measures 42U or just about 6 feet worth of equipment. The RU helps techs to plan the distribution of equipment across racks in data centers.
One of the most important rack space best practices is to make sure you are getting an RTU with the most capabilities possible in only 1U. This will ensure that you don't waste space on other equipment now or later on. Some main examples of RTUs that follow this best practice are:
The NetGuardian 864A maximizes rack space by supporting 64 discrete points, 8 analog inputs, and 8 control relays into only 1U of space.
This power distribution unit (PDU) also has remote telemetry functionality. It only takes 1U and allows you to control power to equipment while still providing 16 discrete alarms, 4 controls, and 2 analog inputs.
The TempDefender takes only 1U half-rack worth of space. It supports 16 analog sensors, so this is the best solution for you if you need maximum analog coverage. Placing 2 TempDefenders next to each other for 32 analog inputs only takes 1U space.
Maximizing your rack space is very important to keep your network efficiency. So, when looking for an RTU make sure it gives you the most alarms and features possible per 1U rack space.
