Choose the right rack cabinet

At PH-EL & Sikring we can offer all kinds of Rack cabinets, from a large selection of manufacturers.

Before choosing a rack cabinet, it is important to assess the size of the cabinet before placing an order.

  • What is the current need?
  • What need could there be in the future, minimum 25% expansion?
  • How are the physical conditions relative to the size of the closet?
  • Should it be a wall-hung rack cabinet?
  • Should it be a floor rack?
  • How to access the installation, removable pages
  • How should data be secured?

If the network is to be spread over several floors, each floor should have its own rack. The rack cabinets should be positioned in such a way that they are above / below each other.

Position the cabinet so that the total cable length of the distribution network becomes as short as possible. Make sure that you have sufficient ground potential and that both racks and panels are grounded.

Choose a rack cabinet that is large enough and has room for possible future extensions. A rule of thumb is that there should be at least 25% free space when the installation is complete. Keep in mind that introverted components usually fill more and more towards the rear edge and therefore the cabinet must be similarly deep.

Ventilation in rack cabinet

It is important that there is plenty of room for cooling / ventilation around the active components to be cooled.

Maintenance of a rack cabinet

Choose a rack cabinet where it is easy to get to ventilation and perform service, e.g. a cabinet with removable side panels. Make sure that there is enough space around the cabinet and that the cabling is properly sized.

Decide which components the rack cabinet should be fitted with:

  • Retractable patch panels provide increased flexibility.
  • Smaller patch panels are easier to handle than large ones.
  • Separate data and telepath panels to reduce the risk of confusion.
  • Selection number of power panels (power outlet)
  • Should the Rack Cabinet be Emergency (UPS)
  • The temperature must be monitored
  • Active or passive ventilation
