Overview
The SR42UBG SmartRack 42U Standard-Depth Rack Enclosure Cabinet is ideal for storing EIA-standard 19-inch rack equipment in network closets, server rooms, data centers and other areas with limited floor space where you need equipment to be secure and organized. Constructed from heavy-duty steel with a durable black powder-coated finish, the cabinet has a maximum stationary load capacity of 3000 lbs (1360.8 kgs).
The front door features a full-length shatter-resistant clear acrylic window that lets you monitor equipment without unlocking the enclosure. Not only does the window help prevent equipment tampering and reduce acoustic noise, but it also adds visual flair to your IT installation.
To ensure your valuable equipment stays secure, the removable side panels, split rear door and reversible front door lock. The rear door and removable top panel are vented, which allows air to flow freely through the cabinet to keep equipment cool. Convenient top ports and an open bottom allow easy cable routing through the cabinet.
The SR42UBG comes partially assembled and ready to deploy with preinstalled casters that let you easily maneuver it into position, where it can be secured by adjusting the removable levelers. Square mounting holes and numbered rack spaces make equipment installation easy. The vertical mounting rails adjust in 1/4-inch increments to accommodate equipment up to 37 inches deep, such as servers and networking switches.

Questions & Answers
It's important to ensure that the server rack is properly cooled, and cold airflow is sufficient to prevent overheating and equipment failure. If you plan on buying a portable or in-rack air conditioner, and need to know how much cooling power you need, here are some helpful tips.
The amount of heat that a server rack produces depends on the type of equipment in the rack, the number of devices installed, and the workload of the equipment. As a general rule, a fully loaded server rack can produce anywhere between 4 and 20 kilowatts of heat.
Further Reading: Server Racks Explained
You can approximate the heat produced by a server rack (and therefore its cooling needs) by calculating the total heat output of all the devices in the rack. Almost all the power consumed by IT devices is converted into heat, so a server that consumes 300W will have a thermal output of approximately 300W (multiply by 3.41 to convert watts to BTU/h).
If your rack includes a UPS, it's even easier. Use the power capacity of the UPS to estimate the cooling load. For example, if the UPS has an output capacity for 1,800 watts, assume the thermal output is 1,800 watts also.
