3. Network Racks: Network racks are very similar to Server and Telco racks, but are not so deep. The standard depth is 600 mm. Network racks typically contain cable connection and routing equipment. The equipment can be mounted further back from the front of the rack to allow for cables to pass and the equipment itself is not so deep, therefore the 600 mm depth is more than enough for cable management in the rear of the rack.
4. Open Racks: These racks are specifically designed for cable management. They do not have tops, sides or doors, so security is not a concern. These racks must have various cable management accessories and are very simple in construction. These are used in communication centers, laboratories, schools and many small offices where cost is a prime concern. Open racks will normally follow the standards for equipment mounting and universal spacing.
5. Industrial Racks: Factory automation and control equipment as well as purpose built electronics will normally be housed in a somewhat customized rack. These may be based on the particular manufacturers requirements or come from the rack manufacturer. They differ from 19” racks in they are not necessarily following the international standards and may also include many other features not found on standard racks. Frequently these racks will be sealed to prevent dust, moisture and sometimes electro-magnetic radiation (EMI) from entering. These racks are used in industrial settings, factories, refineries etc. They would not normally be found in an office or datacenter environment.
4.Rack Selection
How do we know what type of rack and options to use?
The type and size of rack we need to use is defined by what is going inside the rack and where the rack is located.We start by defining what the rack will be housing. We can refer back to category III, to give us some guidelines. Once we have identified what the rack will contain, we need to evaluate the location the rack will be installed. As we stated in the beginning, racks are designed to maximize the efficiency of space utilization, so we want to put the most efficient configuration rack into the space allocated.
At this point we must introduce some new concepts into the planning. Virtually no one buys just one rack. Even if one rack is bought today, within a year or so, the chances are high that additional racks must be added to the site.
Baying: When we have multiple racks assembled at the same site they are frequently “ganged” or “bayed” together. This means the racks are physically joined to each other by some type of baying kit or hardware.
